3+ Ways to Add Bootstrap 4 to Angular 10/9 With Example & Tutorial

In this post we will give you information about 3+ Ways to Add Bootstrap 4 to Angular 10/9 With Example & Tutorial. Hear we will give you detail about 3+ Ways to Add Bootstrap 4 to Angular 10/9 With Example & TutorialAnd how to use it also give you demo for it if it is necessary.

Throughout this tutorial, we’ll learn how to use bootstrap 4 with Angular 10 (and any previous versions such as Angular 9) to make your Angular app responsive.

We’ll learn how to install (and uninstall) bootstrap in Angular from npm, cdn or using the ng add schematic, and add bootstrap to the styles/scripts arrays of the angular.json file. Next, we’ll learn how to build user interfaces with various components such as navigation bars, grid, date and time pickers, tooltips, carousels, modals, tabs, dropdowns, and forms.

We’ll also see the advantages of Angular implementations for Bootstrap  —  ng-bootstrap vs ngx-bootstrap vs mdbootstrap. And see some popular Angular Bootstrap templates that you can use with Angular to quickly create your layouts.

3+ Ways to Add Bootstrap 4 to Angular

In this section, we will see ways to integrate Angular and Bootstrap to style apps built.

We’ll see how to integrate Angular with Bootstrap, in various ways including using ng-bootstrap and ngx-bootstrap packages.

We’ll be using Angular CLI 10 for generating a brand new project.

These are the steps of our tutorial:

  • Step 1 — Installing Angular CLI v10
  • Step 2 — Installing Bootstrap 4 in Your Angular 10 Project
  • Step 3 (Method 1) — Adding Bootstrap 4 to Angular 10 Usingangular.json

What is Bootstrap

Bootstrap is the most popular HTML and CSS framework for building responsive layouts with ease and without having a deep knowledge of CSS (Still custom CSS is required to customize your design and make it different from the other Bootstrap-styled websites unless you are using a BS theme developed specifically for your requirements.

Bootstrap 4 is the latest version of Bootstrap which brings many new and powerful features to the framework most importantly Flexbox which is now the default display system for the Bootstrap grid layout (one of the most important features of Bootstrap).

3+ Ways to Include Bootstrap 4 In Your Angular Project

You can include Bootstrap in your Angular project in multiple ways:

  • Including the Bootstrap CSS and JavaScript files in the <head> section of the index.html file of your Angular project with a <link> and <script> tags,
  • Importing the Bootstrap CSS file in the global styles.css file of your Angular project with an @import keyword.
  • Adding the Bootstrap CSS and JavaScript files in the styles and scripts arrays of the angular.json file of your project

Step 1 — Installing Angular CLI v10

Let’s get started by installing Angular CLI v10 if it is not yet installed on your machine.

Head over to a new command-line interface and run the following command to install the latest version of the Angular CLI:

$ npm install -g @angular/cli

Note: This will install the Angular 10 CLI globally on your system so depending on your npm configuration you may need to add sudo (for superuser access) in macOS and Linux or use a command prompt with admin access in Windows.

After the installation, you’ll have at your disposal the ng utility. Let’s use it to generate a new Angular 10 project as follows:

$ ng new angular-bootstrap-examples

You will be prompted for a couple of questions:

? Would you like to add Angular routing? Yes? Which stylesheet format would you like to use? (Use arrow keys)> CSS  SCSS   [ https://sass-lang.com/documentation/syntax #scss                ]  Sass   [ https://sass-lang.com/documentation/syntax#the-indented-syntax ]  Less   [ http://lesscss.org                                             ]  Stylus [ http://stylus-lang.com                                         ]

Most importantly, choose CSS as the stylesheet format because we’ll use the CSS version of Bootstrap in our tutorial.

The command will generate the directory structure and necessary files for the project and will install the required dependencies.

Next, navigate inside the root folder of your project:

$ cd angular-bootstrap-examples

You can then serve your Angular 10 application using the ng serve command as follows:

$ ng serve

Your app will be served from http://localhost:4200/

Step 2 — Installing Bootstrap 4 in Your Angular 10 Project

In this step, we’ll proceed to add Bootstrap 4 to our Angular 10 application.

There are various ways that you can use to install Bootstrap in your project:

  • Installing Bootstrap from npm using the npm install command,
  • Downloading Bootstrap files and adding them to the src/assets folder of your Angular project,
  • Using Bootstrap from a CDN.

Let’s proceed with the first method. Go back to your command-line interface and install Bootstrap 4 via npm as follows:

$ npm install bootstrap

This will also add the bootstrap package to package.json. At the time of writing this tutorial, bootstrap v4.3.1 will be installed.

The Bootstrap 4 assets will be installed in the node_modules/bootstrap folder. You’ll need to tell Angular where to look for them.

Next, you also need to install jQuery using the following command:

$ npm install jquery

At the time of this tutorial jquery v3.4.1 will be installed.

Step 3 (Method 1) — Adding Bootstrap 4 to Angular 10 Using angular.json

Open the angular.json file of your project and include:

  • node_modules/bootstrap/dist/css/bootstrap.css in the projects->architect->build->styles array,
  • node_modules/bootstrap/dist/js/bootstrap.js in the projects->architect->build->scripts array,
  • node_modules/bootstrap/dist/js/bootstrap.js in the projects->architect->build->scripts array,

As follows:

{"$schema":"./node_modules/@angular/cli/lib/config/schema.json","version":1,"newProjectRoot":"projects","projects":{"angular-bootstrap-examples":{"projectType":"application","schematics":{},"root":"","sourceRoot":"src","prefix":"app","architect":{"build":{"builder":"@angular-devkit/build-angular:browser","options":{"outputPath":"dist/angular-bootstrap-examples","index":"src/index.html","main":"src/main.ts","polyfills":"src/polyfills.ts","tsConfig":"tsconfig.app.json","aot":true,"assets":["src/favicon.ico","src/assets"],"styles":["./node_modules/bootstrap/dist/css/bootstrap.css","src/styles.css"],"scripts":["./node_modules/jquery/dist/jquery.js","./node_modules/bootstrap/dist/js/bootstrap.js"]},

Note: You also need to add the jQuery JavaScript library file.

Step 3 (Method 2) — Adding Bootstrap 4 to Angular 10 Using index.html

You can also include Bootstrap files from node_modules/bootstrap using the index.html file.

Open the src/index.html file and add the following tags:

  • A <link> tag for adding the bootstrap.css file in the <head> section,
  • A <script> tag for adding the jquery.js file before the closing </body> tag,
  • A <script> tag for adding the bootstrap.js file before the </body> tag.

This is an example:

<!doctype html><htmllang="en"><head><metacharset="utf-8"><title>Angular Bootstrap 4 Examples</title><basehref="/"><metaname="viewport"content="width=device-width, initial-scale=1"><linkrel="icon"type="image/x-icon"href="favicon.ico"><linkrel="stylesheet"href="../node_modules/bootstrap/dist/css/bootstrap.css"></head><body><app-root></app-root><script src="../node_modules/jquery/dist/jquery.js"></script><script src="../node_modules/bootstrap/dist/js/bootstrap.js"></script></body></html>

Step 3 (Method 3) — Adding Bootstrap 4 to Angular 10 Using styles.css

We can also use the styles.css file to add the CSS file of Bootstrap to our project.

Open the src/styles.css file of your Angular project and import the bootstrap.css file as follows:

@import"~bootstrap/dist/css/bootstrap.css"

This replaces the previous method(s), so you don’t need to add the file to the styles array of the angular.json file or to the index.html file.

Note: The JavaScript file(s) can be added using the scripts array or the <script> tag like the previous methods.

Alternative Step — Adding Bootstrap 4 Using ng-bootstrap and ngx-bootstrap

Bootstrap depends on the jQuery and popper.js libraries, and if you don’t include them in your project, any Bootstrap components that rely on JavaScript will not work.

Why not include those libs? For Angular, it’s better to avoid using libraries that make direct manipulation of the DOM (like jQuery) and let Angular handle that.

Now, what if you need the complete features of Bootstrap 4 without the JavaScript libraries?

A better way is to use component libraries created for the sake of making Bootstrap work seamlessly with Angular such as ng-bootstrap andngx-bootstrap

Should I add bootstrap.js or bootstrap.min.js to my project? No, the goal of ng-bootstrap is to completely replace JavaScript implementation for components. Nor should you include other dependencies like jQuery or popper.js. It is not necessary and might interfere with ng-bootstrap code Source

So first you’ll need to install the library from npm using the following command:

$ npm install @ng-bootstrap/ng-bootstrap

Once you finish the installation, you’ll need to import the main module:

import{NgbModule}from'@ng-bootstrap/ng-bootstrap';

Next, you’ll need to add the module you imported in your app root module as follows:

import{NgbModule}from'@ng-bootstrap/ng-bootstrap';@NgModule({declarations:[/*...*/],imports:[/*...*/,NgbModule.forRoot()],/*...*/})exportclassAppModule{}

Please note that ng-bootstrap requires the Bootstrap 4 CSS file to be present.

You can add it in the styles array of the angular.json file as follows:

"styles":["styles.css","../node_modules/bootstrap/dist/css/bootstrap.css"],

Now, you can use Bootstrap 4 in your Angular application.

You can find all the available components via this link.

You can also use the ngx-bootstrap library. Simply head back to your terminal, make sure you are inside your Angular project then run the following command to install ngx-bootstrap:

$ npm install ngx-bootstrap

You also need the Bootstrap 4 CSS files. Add the following line in the <head> of your Angular app which includes Bootstrap from a CDN:

<linkhref="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"rel="stylesheet">

You can also install bootstrap from npm and use the previous way to include the CSS file (via the styles array in the angular-cli.json file):

"styles":["../node_modules/bootstrap/dist/css/bootstrap.min.css","styles.css"],

Next, open the src/app/app.module.ts file and update is as follows:

import{BsDropdownModule}from'ngx-bootstrap/dropdown';import{AlertModule}from'ngx-bootstrap';/*...*/@NgModule({/*...*/imports:[BsDropdownModule.forRoot(),AlertModule.forRoot(),/*...*/],/*...*/})

This an example of importing two components BsDropdownModule and AlertModule.

You need to import the module for each component you want to use in the same way.

ngx-bootstrap provides each Bootstrap component in each own module so you only import the components you need. In this way, your app will be smaller since it bundles only the components you are actually using.

You can find all the available components that you can use from the docs.

Adding Bootstrap 4 to Angular 10 Using Schematics

Thanks to the new ng add command added on Angular 7+, you have a new simpler and easier way to add Bootstrap without using the npm install command for installing the required dependencies or adding any configurations.

You can simply run the following command to add ng-bootstrap:

$ ng add @ng-bootstrap/schematics

That’s it. You now have support for Bootstrap components and styles without any extra configurations. You also don’t need jQuery since we are using ng-bootstrap.

Summary

In this section, we’ve seen different ways of including Bootstrap 4 in Angular 10 apps, such as:

  • Using original Bootstrap 4 assets from npm,
  • Using the ng-bootstrap library,
  • And finally using the ngx-bootstrap

The most important difference between ng-bootstrap vs. ngx-bootstrapis that ngx-bootstrap uses separate modules for components to reduce the final app size.

Styling an Angular 10 Example App with Bootstrap 4 Navbar, Jumbotron, Tables, Forms, and Cards

In this section, we’ll learn how to integrate and use bootstrap 4 with Angular 10 by building an example application step by step.

We’ll see how to initialize an Angular 10 project and integrate it with Bootstrap 4. Next, we’ll use the various Bootstrap 4 CSS utilities to create a responsive layout with navbars, tables, forms, buttons, cards, and jumbotrons.

Bootstrap is a free and open-source CSS framework for creating responsive layouts, it’s mobile-first and contains ready CSS utilities for typography, forms, buttons, and navigation, etc.

This tutorial works with all recent versions of Angular i.e version 7, 8, 9 and 10.

There are various ways of integrating Angular with Bootstrap that we have seen in the previous section. Let’s see a possible solution by example. These are the steps of this section:

  • Step 1 — Installing Angular CLI 10
  • Step 2 — Initializing your Angular 10 Project
  • Step 3 — Installing Bootstrap 4
  • Step 4 — Creating Angular Components and Setting up Routing
  • Step 5 — Adding a Bootstrap 4 Jumbotron
  • Step 6 — Creating an Angular Bootstrap 4 Table
  • Step 7 — Adding a Bootstrap 4 Form Component

Step 1 — Installing Angular CLI 10

Let’s start by installing the latest version of Angular CLI. In your terminal, run the following command:

$ npm install -g @angular/cli

Step 2 — Initializing your Angular 10 Project

After installing Angular CLI, let’s initialize an Angular 10 project by running the following command:

$ ng new angular10bootstrapexample

The CLI will then ask you:

Would you like to add Angular routing?

Press Y.

Next, it will ask you:

Which stylesheet format would you like to use?

Choose “CSS”.

Next, we need to set up Angular 10 forms.

Go to the src/app/app.module.ts file, import FormsModule from @angular/forms, and include it in the imports array as follows:

import{BrowserModule}from'@angular/platform-browser';import{NgModule}from'@angular/core';import{AppRoutingModule}from'./app-routing.module';import{FormsModule}from'@angular/forms';@NgModule({declarations:[/* ... */],imports:[BrowserModule,AppRoutingModule,FormsModule],providers:[],bootstrap:[AppComponent]})exportclassAppModule{}

Step 3 — Installing Bootstrap 4

After initializing your Angular 10 project, let’s proceed to install Bootstrap 4 and integrate it with Angular.

Go to your project’s folder:

$ cd angular10bootstrapexample

Next, install Bootstrap 4 and jQuery from npm using the following command:

$ npm install bootstrap jquery

Next, go the angular.json file and add the paths of Bootstrap CSS and JavaScript files as well as jQuery to the styles and scripts arrays under the build target as follows:

"architect":{"build":{[...],"styles":["src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"],"scripts":["node_modules/jquery/dist/jquery.min.js","node_modules/bootstrap/dist/js/bootstrap.min.js"]},

Step 4 — Creating Angular Components and Setting up Routing

After installing and integrating Bootstrap 4 with your Angular 10 project, let’s create some components to test various Bootstrap styles.

Go to your command-line interface and run the following commands:

$ ng generate component jumbotron$ ng generate component bootstrap-form$ ng generate component bootstrap-table

Next, we need to include these components in the routing module to enable multiple views.

Go to the src/app/app-routing.module.ts file and update it as follows:

import{NgModule}from'@angular/core';import{Routes,RouterModule}from'@angular/router';import{BootstrapTableComponent}from'./bootstrap-table/bootstrap-table.component';import{BootstrapFormComponent}from'./bootstrap-form/bootstrap-form.component';import{JumbotronComponent}from'./jumbotron/jumbotron.component';constroutes:Routes=[{path:"",pathMatch:"full",redirectTo:"home"},{path:"jumbotron",component:JumbotronComponent},{path:"bootstrap-form",component:BootstrapFormComponent},{path:"bootstrap-table",component:BootstrapTableComponent}];@NgModule({imports:[RouterModule.forRoot(routes)],exports:[RouterModule]})exportclassAppRoutingModule{}

Step 5 — Adding A Bootstrap 4 Jumbotron

A Bootstrap Jumbotron is a lightweight, flexible component that can optionally extend the entire viewport to showcase key marketing messages on your site

Let’s add a Bootstrap Jumbotron component to our jumbotron page.

Head to the src/app/jumbotron/jumbotron.component.html file and add the following HTML markup:

<divclass="jumbotron"style="height: calc(95vh);"><h1>Angular 10 Bootstrap 4 Demo</h1><pclass="lead">    This tutorial teaches you how to integrate Bootstrap 4 with Angular 10    </p></div>

We use the built-in .jumbotron class to create a Bootstrap Jumbotron.

Step 6 — Creating an Angular 10 and Bootstrap 4 Table

Let’s now see how to use a Bootstrap 4 table to display tabular data.

Go the src/app/bootstrap-table/bootstrap-table.component.ts file and add some data that we can display:

import{Component,OnInit}from'@angular/core';@Component({selector:'app-bootstrap-table',templateUrl:'./bootstrap-table.component.html',styleUrls:['./bootstrap-table.component.css']})exportclassBootstrapTableComponentimplementsOnInit{employees=[{id:1,name:"E 001",description:"E 001 des",email:"e001@email.com"},{id:2,name:"E 002",description:"E 002 des",email:"e002@email.com"},{id:3,name:"E 003",description:"E 003 des",email:"e003@email.com"},{id:4,name:"E 004",description:"E 004 des",email:"e004@email.com"}];selectedEmployee;constructor(){}ngOnInit(){}publiccreateEmployee(e:{id,name,description,email}){this.employees.push(e);}publicselectEmployee(e){this.selectedEmployee=e;}}

We simply defined two variables employees and selectedEmployee for holding the set of employees and the selected employee. And a selectEmployee() method which assigns the selected employee to the selectedEmployee variable.

Next, go to the src/app/bootstrap-table/bootstrap-table.component.html file and update it as follows:

<divclass="container"style="margin-top: 70px;"><tableclass="table table-hover"><thead><tr><th>#</th><th>Name</th><th>Email</th><th>Actions</th></tr></thead><tbody><tr*ngFor="let employee of employees"><td></td><td></td><td></td><td><buttonclass="btn btn-primary"(click)="selectEmployee(employee)"> Select</button></td></tr></tbody></table><divclass="card text-center"*ngIf="selectedEmployee"><divclass="card-header">        #       </div><divclass="card-block"><h4class="card-title"></h4><pclass="card-text"></p></div></div></div>

A Bootstrap 4 Card is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. If you’re familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.

We use the built-in .table and .table-hover classes to create Bootstrap tables, the .card, .card-block, .card-title and .card-text classes to create cards.

Step 7 — Adding A Bootstrap 4 Form Component to your Angular 10 App

Let’s proceed by adding a Bootstrap-styled form to the bootstrap-form component.

Next, go to the src/app/bootstrap-form/bootstrap-form.component.ts file and update it as follows:

import{Component,OnInit}from'@angular/core';@Component({selector:'bootstrap-form/-create',templateUrl:'./bootstrap-form/.component.html',styleUrls:['./bootstrap-form/.component.css']})exportclassBootstrapForm/ComponentimplementsOnInit{employee:{id,name,description,email}={id:null,name:"",description:"",email:""};constructor(){}ngOnInit(){}createEmployee(){console.log("Employee created: ",this.employee);this.employee={id:null,name:"",description:"",email:""};}}

Next, go to the src/app/bootstrap-form/bootstrap-form.component.html file and update it as follows:

<div  style="margin-top: 70px;">  <div >    <div >      <div>        <form>          <div >            <label for="id">ID</label>            <input [(ngModel)]="employee.id" type="text" name="id"  id="id" aria-describedby="idHelp" placeholder="Employee ID">            <small id="idHelp" >Enter your employee’s ID</small>            <label for="name">Employee Name</label>            <input [(ngModel)]="employee.name" type="text" name="name"  id="name" aria-describedby="nameHelp" placeholder="Enter your employee name">            <small id="nameHelp" >Enter your employee’s name</small>            <label for="email">Employee Email</label>            <input [(ngModel)]="contact.email" type="text" name="email"  id="email" aria-describedby="emailHelp"              placeholder="Enter your employee email">            <small id="nameHelp" >Enter your employee’s email</small>            <label for="description">Employee Description</label>            <pre [(ngModel)]="employee.description" name="description"  id="description" aria-describedby="descHelp">                      </pre>            <small id="descHelp" >Enter your employee’s description</small>          </div>        </form>        <button  (click)="createEmployee()">Create employee</button>      </div>    </div>  </div></div>

We make use of the .form-group and .form-control classes to create a Bootstrap form.

Step 8 — Serving your Angular 10 Application

Head over to your command-line interface, and run the following command from the folder of your project:

$ ng serve

A development server will be started at the http://localhost:4200 address.

Summary

As a recap, we have seen how to initialize an Angular 10 project and integrate it with Bootstrap 4. Next, we used various Bootstrap CSS utilities to create a responsive layout with tables, forms, buttons, cards and jumbotrons.

Angular 10 Carousel Example with Bootstrap 4

In this tutorial, we’ll learn how to create a carousel with the latest Angular 10 version and Bootstrap 4.

The carousel is a slideshow for cycling through a series of content, built with CSS 3D transforms and a bit of JavaScript. It works with a series of images, text, or custom markup. It also includes support for previous/next controls and indicators. Source

Before getting started you need a few prerequisites:

  • Basic knowledge of TypeScript. Particularly the familiarity with Object Oriented concepts such as TypeScript classes and decorators.
  • A local development machine with Node 10+, together with NPM 6+ installed. Node is required by the Angular CLI like the most frontend tools nowadays. You can simply go to the downloads page of the official website and download the binaries for your operating system. You can also refer to your specific system instructions for how to install Node using a package manager. The recommended way though is using NVM — Node Version Manager — a POSIX-compliant bash script to manage multiple active Node.js versions.

Note: If you don’t want to install a local environment for Angular development but still want to try the code in this tutorial, you can use Stackblitz, an online IDE for frontend development that you can use to create an Angular project compatible with Angular CLI.

Step 1 — Installing Angular CLI 10

Let’s start by installing the latest Angular CLI 10 version.

Angular CLI is the official tool for initializing and working with Angular projects. Head over to a new command-line interface and run the following command:

$ npm install -g @angular/cli

At the time of writing this tutorial, angular/cli v10 will be installed on your system.

Step 2 — Creating a New Angular 10 App

In the second step, let’s create our project. Head back to your command-line interface and run the following commands:

$ cd ~$ ng new angular10carousel

The CLI will ask you a couple of questions — If Would you like to add Angular routing? Type y for Yes and Which stylesheet format would you like to use? Choose CSS.

Next, navigate to you project’s folder and run the local development server using the following commands:

$ cd angular10carousel$ ng serve    

Open your web browser and navigate to the http://localhost:4200/ address to see your app running.

Step 3 — Installing Ng-Bootstrap

Next, we need to install ng-bootstrap using the following command:

$ ng add @ng-bootstrap/ng-bootstrap

This library provides an Angular implementation for Bootstrap 4 so you don’t need to use jQuery.

Open the src/app/app.component.ts file and update it as follows:

import{Component}from'@angular/core';import{NgbCarouselConfig}from'@ng-bootstrap/ng-bootstrap';@Component({selector:'my-app',templateUrl:'./app.component.html',styleUrls:['./app.component.css'],providers:[NgbCarouselConfig]// add NgbCarouselConfig to the component providers})exportclassAppComponent{images=[700,800,807].map((n)=>'https://picsum.photos/id/${n}/900/500');constructor(config:NgbCarouselConfig){// config.interval=2000;config.keyboard=true;config.pauseOnHover=true;}}

We import NgbCarouselConfig and add it to the providers array of the component, next we inject it via the constructor and use it to customize default values of carousels used by this component and its children. We set the interval between slides to two seconds, enabled the keyboard to move slides, and pause on hover on each slide.

We also defined an array of images to use for slides.

Next, open the src/app/app.component.html file and update it as follows:

<divclass="container-fluid"><h1>Angular 10 Carousel Example</h1><h2>Full tutorial in Techiediaries</h2><ngb-carousel*ngIf="images"><ng-templatengbSlide><divclass="wrapper"><img[src]="images[]"alt="Random first slide"></div><divclass="carousel-caption"><h3>First Slide</h3> Angular 10 Carousel Example </p></div></ng-template><ng-templatengbSlide><divclass="wrapper"><img[src]="images[1]"alt="Random second slide"></div><divclass="carousel-caption"><h3>Second Slide</h3> Check out Techiediaries</p></div></ng-template><ng-templatengbSlide><divclass="wrapper"><img[src]="images[2]"alt="Random third slide"></div><divclass="carousel-caption"><h3>Third Slide</h3>for full tutorial...</p></div></ng-template></ngb-carousel></div>

We use ng-template with the ngbSlide directive for add a carousel slide and we use HTML to define the content for the slide.

Next, open the src/app/app.component.html file and add the following styles:

ngb-carousel.wrapper{position:relative;height:;padding-top:55%;/* Keep ratio for 900x500 images */}ngb-carousel.wrapper>img{position:absolute;top:;left:;bottom:;right:;}

You can play with this example from https://stackblitz.com/edit/angular-10-carousel-example

Summary

In this tutorial, we’ve seen how to create a carousel with rich slides in Angular 10 using ng-bootstrap.

Angular 10 Rating Example With Ng-Bootstrap

In this section, we’ll see by example how to create a rating component with Bootstrap 4, HTML Select and Angular 10 Forms. We’ll be using the ngb-rating component from ng-bootstrap. We’ll also see how to use the HTML select control with the ngFor directive inside a reactive form. How to bind select element to a TypeScript object or string literal using [ngValue] and value properties respectively, and how to assign a default value to select from an array of elements.

NgBoostrap is the Angular adapted version of Bootstrap UI components. Using ng-bootstrap we can easily integrate bootstrap library to our Angular project and use it’s awesome UI components very easily. Bootstrap is tried and tested and fully responsive for multiple platforms and screen sizes. Moreover, it is now an industrial standard adopted almost everywhere.

HTML forms are necessary in most web applications. Selects in forms can be used when you have multiple options and want users to select one of them before submitting the form. In Angular, you can use objects for option values and not only strings.

This is an example of a component template with the select control:

<form[formGroup]="myForm"><selectformControlName="myControl"><option[value]="city"*ngFor="let city of cities"></option></select></form>

In our Angular component, we need to have a cities array with some cities.

We use the value property to bind the city to select but you can also use ngValue instead. The value property is used with string literals only, whereas ngValue can be used with objects. We’ll see next another example of using select with objects instead of strings.

This comes handy if we have a drop-down where we need to show the names of the objects from a TypeScript array. But when selecting the element from the drop-down you need to select the id of the array element for querying the database for example. In this case, we need to use ngValue as it works with TypeScript objects and not just strings.

In the previous tutorial, you’ve seen how you can install Angular 10 CLI from npm, so let’s start by creating a new project.

Creating a New Angular 10 Project

Let’s get started by creating a new Angular 10 project using the following command:

$ ng new AngularRatingExample? Would you like to add Angular routing? Yes? Which stylesheet format would you like to use? CSS

Adding Ng-Bootstrap

We’ll see how to set up Bootstrap in our project for styling our UI using ng-bootstrap. For that purpose, we’ll first need to add bootstrap and ng-bootstrap from npm in our project using the following command:

$ cd AngularRatingExample$ ng add @ng-bootstrap/ng-bootstrap

This will install ng-bootstrap for the default application specified in your angular.json file.

Since ng-bootstrap has a dependency on i18n, we’ll also need add the package to our project using the following command:

$ ng add @angular/localize

Next, open the src/app/app.module.ts file and add NgbModule and ReactiveFormsModule in the imports array of AppModule as follows:

// [...]import{ReactiveFormsModule}from'@angular/forms';import{NgbModule}from'@ng-bootstrap/ng-bootstrap';@NgModule({imports:[// [...]ReactiveFormsModule,NgbModule],})

Next, open the src/app/app.component.html file and update it as follows:

<divclass="container"><divclass="row"><divclass="col-12"><router-outlet></router-outlet></div></div></div>

We simply wrap the router outlet with some HTML markup styled with Bootstrap 4.

Creating an Angular 10 Rating Component

Next, let’s create an Angular 10 component that will encapsulate our form. Head back to your terminal and run the following command:

$ ng generate component rating

Using the HTML Select Control with the ngFor Directive with a Reactive Form

Next, open the src/app/rating/rating.component.html file and add the following form:

<form[formGroup]="form"(ngSubmit)="submit()"><divclass="form-group"><label>Book</label><selectformControlName="book"><option*ngFor="let book of books"[ngValue]="book"></option></select></div><divclass="form-group"><ngb-rating[max]="5"formControlName="rating"></ngb-rating></div><button[disabled]="form.invalid||form.disabled"class="btn btn-primary">Rate the book!</button></form>

We used the HTML select element with ngValue, and the ngFor directive inside our reactive form.

*ngFor is the Angular repeater directive. It simply repeats the host element for each element in a list.

The syntax in this example is as follows:

  • <option> is the host element.
  • books holds the books list from the RatingComponent class.
  • book holds the current book object for each iteration through the list.

Next, update the src/app/rating/rating.component.ts file as follows:

// [...]exportclassRatingComponentimplementsOnInit{books=[{name:'Book 1'},{name:'Book 2'},{name:'Book 3'},{name:'Book 4'},{name:'Book 5'}];form=newFormGroup({book:newFormControl(this.books[],Validators.required),rating:newFormControl('',Validators.required),});submit(){console.log(JSON.stringify(this.form.value));this.form.reset();}}

We also provided a default value from the array books for select using book: new FormControl(this.books[0], Validators.required). The first parameter is the default value.

Next, we need to add our rating component to the router configuration. Open the src/app/app-routing.module.ts file and update it as follows:

import{NgModule}from'@angular/core';import{Routes,RouterModule}from'@angular/router';import{RatingComponent}from'../rating/rating.component.ts';constroutes:Routes=[{path:'',component:RatingComponent}];@NgModule({imports:[RouterModule.forRoot(routes)],exports:[RouterModule]})exportclassAppRoutingModule{}

Finally, you can start your development server using the following command:

$ ng serve

Summary

In this Angular 10 tutorial, we’ve covered building a basic form with a rating component based on the ngb-rating component from ng-bootstrap. We have seen how to use the HTML select control with the ngFor directive inside a reactive form. How to bind select to a TypeScript object instead of string and how to assign a default value to select.

Angular 10 Star Rating Example

In this section, we’ll build a star rating component with the latest Angular 10 version and Bootstrap.

Star rating is a common feature in product recommendation and eCommerce websites

We commonly rate something between zero and five stars.

Before getting started you need a few prerequisites:

  • Basic knowledge of TypeScript. Particularly the familiarity with Object Oriented concepts such as TypeScript classes and decorators.
  • A local development machine with Node 10+, together with NPM 6+ installed. Node is required by the Angular CLI like the most frontend tools nowadays. You can simply go to the downloads page of the official website and download the binaries for your operating system. You can also refer to your specific system instructions for how to install Node using a package manager. The recommended way though is using NVM — Node Version Manager — a POSIX-compliant bash script to manage multiple active Node.js versions.

Note: If you don’t want to install a local environment for Angular development but still want to try the code in this tutorial, you can use Stackblitz, an online IDE for frontend development that you can use to create an Angular project compatible with Angular CLI.

Step 1 — Installing Angular CLI 10

Let’s begin by installing the latest Angular CLI 10 version (at the time of writing this tutorial).

Angular CLI is the official tool for initializing and working with Angular projects. To install it, open a new command-line interface and run the following command:

$ npm install -g @angular/cli

At the time of writing this tutorial, angular/cli v10 will be installed on your system.

Step 2 — Creating a New Angular 10 App

In the second step, let’s create our project. Head back to your command-line interface and run the following commands:

$ cd ~$ ng new angular10star-rating

The CLI will ask you a couple of questions — If Would you like to add Angular routing? Type y for Yes and Which stylesheet format would you like to use? Choose CSS.

Next, navigate to you project’s folder and run the local development server using the following commands:

$ cd angular10star-rating$ ng serve    

Open your web browser and navigate to the http://localhost:4200/ address to see your app running.

Step 3 — Installing Ng-Bootstrap

Next, we need to install ng-bootstrap using the following command:

$ ng add @ng-bootstrap/ng-bootstrap

This library provides an Angular implementation for Bootstrap 4 and also provides some useful components such as NgbRating — a directive that allows you to display star rating bar.

Open the src/app/app.component.ts file and update it as follows:

import{Component}from'@angular/core';@Component({selector:'app-root',templateUrl:'./app.component.html',styleUrls:['./app.component.css']})exportclassAppComponent{currentRate=;}

Next, open the src/app/app.component.html file and update it as follows:

<h1class="text-primary">Angular 10 Start Rating Example</h1><ngb-rating[max]="5"[(rate)]="currentRate"[readonly]="false"></ngb-rating>Rate: </p>

Next, open the src/app/app.component.css file and add the following CSS styles:

ngb-rating{font-size:100px;color:brown;background:rgba(23,221,16,0.815);}

You can find this example in https://stackblitz.com/edit/angular-10-star-rating-example

Summary

In this short article, we’ve seen how to create a star rating component with Angular 10 and ng-bootstrap. Read the official docs for more details.

Creating an Angular Calendar with ngx-bootstrap Datepicker

In this tutorial, we’ll see how to create an Angular 9 calendar UI with the datepicker component available from ngx-bootstrap.

We’ll learn to build a calendar component using bootstrap and ngx-bootstrap datepicker component.

Date pickers are commonly used in web apps for choosing dates.

Dates can be selected by navigating between various dates using UI.

The ngx-bootstrap library provides a datepicker component with many configuration options that you can use to customize the calendar view in your Angular 9 web app.

Throughout this tutorial, we will learn with steps to build a calendar component.

Let’s start bu initializing a new Angular 9 app for our calendar example using Angular CLI.

We need to have the following prerequisites:

  • Node.js and NPM installed on your development machine,
  • Angular CLI v9 installed on your machine.

Generating your Angular Project

Open a new command-line interface and run the following command:

ng new angular-calendar-example

Navigate to your project’s folder using:

cd angular-calendar-example

Adding Bootstrap to Angular

Next, we need to integrate bootstrap and ngx-bootstrap with your Angular 9 project.

First, run the following command to install bootstrap 4 from npm:

npm install bootstrap 

Next, install the ngx-bootstrap package:

$ npm install ngx-bootstrap --save

Importing and Configuring the Datepicker Component

Open the angular.json file and add the following styling:

"styles":["node_modules/bootstrap/dist/css/bootstrap.min.css","node_modules/ngx-bootstrap/datepicker/bs-datepicker.css","src/styles.css"]

Next, we need to import the date picker component. Open src/app/app.module.ts file and update it as follows:

import{BrowserModule}from'@angular/platform-browser';import{NgModule}from'@angular/core';import{AppComponent}from'./app.component';import{BrowserAnimationsModule}from'@angular/platform-browser/animations';import{BsDatepickerModule}from'ngx-bootstrap/datepicker';@NgModule({declarations:[AppComponent],imports:[BrowserModule,BrowserAnimationsModule,BsDatepickerModule.forRoot()],providers:[],bootstrap:[AppComponent]})exportclassAppModule{}

Adding a Calendar UI in your Angular 9 Template

Next, let’s add a calendar component. Open the src/app/app.component.html file and add the following HTML code:

<div >  <div >    <div >      <input type="text"            placeholder="Choose date"                        bsDatepicker>    </div>    <div >      <input        type="text"        placeholder="Choose date"                bsDatepicker        bsDaterangepicker        [bsConfig]="{ isAnimated: true }">    </div>  </div></div>

That’s it, save your file and run the following command in your terminal:

ng serve

Summary

In this tutorial, we have a simple example of a calendar with the datepicker component of ngx-bootstrap.

Appendix 1: Bootstrap 4 Card Explained

In this section, we’ll learn about the new Card component introduced in Bootstrap 4 which replaces many old components in Bootstrap 3, and can be used to build modern style web layouts without re-inventing the well or being a CSS designer with deep CSS knowledge. Now and thanks to Bootstrap 4 you can, as a developer with small CSS knowledge, build modern and professional card-based layouts.

Bootstrap cards provide flexible containers for displaying a mix of content (text, images, links, etc.) in a grouped way. They can be created by only adding a bunch of CSS classes to HTML markup and they can be easily styled and customized to present a new and distinguished look.

Cards are used to create advanced layouts such as Masonry. You’ll find cards in many big web platforms such as e-commerce websites, analytics dashboards, and blogs etc.

For Bootstrap users, Cards are a replacement for the popular components : panels, thumbnails and wells (all these can now be created with cards)

Before we start seeing how to create different card types. These are a summary of information about Bootstrap 4 Cards

  • Cards are used to present a mix of content in an elegant and compact way
  • Cards are built on top of Flexbox
  • Cards have no margin by default
  • Cards can be easily organized in groups, decks or Masonry columns
  • Cards have a header, footer, and one or more bodies
  • Cards can be easily aligned and well mixed with the other Bootstrap components etc.

In this tutorial you will get introduced to the new card component then you will see different elements of a card and finally you will build a Masonry-like layout using Cards and Card Columns

First, start by creating an HTML file andcopy the following starter template from the Bootstrap docs in the new file:

<!doctype html><htmllang="en"><head><!-- Required meta tags --><metacharset="utf-8"><metaname="viewport"content="width=device-width, initial-scale=1, shrink-to-fit=no"><!-- Bootstrap CSS --><linkrel="stylesheet"href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm"crossorigin="anonymous"><title>Bootstrap 4 Card Example</title></head><body><divclass="container"><!-- Our Simple Card Goes Here --></div><!-- Optional JavaScript --><!-- jQuery first, then Popper.js, then Bootstrap JS --><script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN"crossorigin="anonymous"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js"integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q"crossorigin="anonymous"></script><script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl"crossorigin="anonymous"></script></body></html>

Now let’s start by creating a basic card. Add a <div> with the class .card to create the outer container of your card component.

Next inside the outer container, add a header, card body, and footer.

You can add a header by either creating a <div> or <h*> heading element then add the .card-header class.

You can create a card body by adding a .card-body class to a <div>.

For the footer, you need to add a <div> with the class .card-footer:

<divclass="card"><divclass="card-header">        Card Header        </div><divclass="card-body">        Card Body    </div><divclass="card-footer">        Card Footer    </div></div>

Please note that you can add one or many card bodies to your card and you can also wrap the content inside the body in other tags such as :

<div >            You can also add a second body    </p></div>

Use a card body when you want to create a padded section within a card.

  • Using .card-img-top and card-img-bottom you can create image caps which are images that exist on the top and bottom of the card body/bodies
<imgclass="card-img-top"src="https://source.unsplash.com/daily"alt="Card image top"><divclass="card-body"></div><imgclass="card-img-bottom"src="https://source.unsplash.com/daily"alt="Card image bottom">

You can see that the card component is taking the whole width of its container division but you can control the width with different means:

  • using the width and max-width CSS properties
<divclass="card"style="width:20rem;">...</div>
  • using the Bootstrap 4 Grid

You can also set the height but in most cases the height needs to fit the vertical alignment of the card content so you’ll rarely need to set it.

For adding content inside the card body you also have a bunch of classes (.card-title, .card-subtitle, .card-text) that make it easy to style different content types such as the card title, subtitle and text.

You can use standard HTML tags to style text within .card-text class

<divclass="card-body"><h3class="card-title">Card title</h3><h4class="card-subtitle">Card subtitle</h4><pclass="card-text">This is a card body 1</p></div>

Want to use the cap image as an overlay? you can simply switch the .card-body class with the .card-img-overlay class

<divclass="card"><imgclass="card-img-top"src="https://source.unsplash.com/daily?nature"alt="Card image top"><divclass="card-img-overlay"><h3class="card-title">Card 2 title</h3><h4class="card-subtitle">Card 2 subtitle</h4><pclass="card-text">This is a card 2 body </p></div></div>

You can add navigation tabs and pills to the header of your card using nav, nav-tabs|nav-pills, card-header-tabs| card-header-pill classes with <ul> tags

<divclass="card-header"><ulclass="nav nav-tabs card-header-tabs"><liclass="nav-item"><aclass="nav-link active"href="#">Tab 1</a></li><liclass="nav-item"><aclass="nav-link"href="#">Tab 2</a></li></ul></div>

You can add links to card content using the .card-link class with an <a> element

<divclass="card"><imgclass="card-img-top"src="https://source.unsplash.com/daily?rock"alt="Card image top"><divclass="card-img-overlay white"><h3class="card-title">Card title</h3><h4class="card-subtitle">Card  subtitle</h4><pclass="card-text">You can add links to card body</p><ahref="#"class="card-link">Link 1</a><ahref="#"class="card-link">Link 2</a></div></div>

You can use list as body content. For example this is how you can create two stylish lists without any extra custom CSS

<divclass="card text-primary border-primary"><ulclass="list-group"><liclass="list-group-item">Item 1</li><liclass="list-group-item">Item 2</li><liclass="list-group-item">Item 3</li></ul></div><br><divclass="card text-primary border-primary"><divclass="card-body"><h2class="card-title"> My List</h2><ulclass="list-group list-group-flush"><liclass="list-group-item">Item 1</li><liclass="list-group-item">Item 2</li><liclass="list-group-item">Item 3</li></ul></div>

How to Create Complex Card Based Layouts?

Singe cards are great way to display a mix of content but usually you need to display a collection of cards to build complex layouts such as Masonry like layouts.

Bootstrap Card Groups

You can create a single unit of multiple cards using Cards. The columns of the unit will take the same width and height (this is achieved using Flexbox).

This is an example of a group of 3 cards

Bootstrap Card Decks

Card Decks are similar to Card Groups except that individual cards inside a deck are not attached

Bootstrap Card Columns

Cards Columns provides a grouping that organizes cards into a masonry like (Pinterest style) layout. You don’t need to provide extra CSS or JavaScript/jQuery code just wrap your cards inside a <div> with .card-columns and Bootstrap 4 will present you with a Masonry layout. But keep in mind this is just CSS not JavaScript code involved so the masonry layout is simple, cards are ordered from top-left, bottom-right and there is no easy way to chage this behavior unless you are using to a Mosonry plugin.

See the following pen for an example

Summary

In this section, we’ve introduced the Card component.

Thanks to Bootstrap 4 you will no more be intimidated when you want to create modern style and card-based layouts even if you are just starting with HTML and CSS or you are a developer with no extensive knowledge of CSS.

Appendix 2: Bootstrap 4 Grid/Flexbox Explained

In this section, we’ll learn about the Grid layout based on Flexbox in Bootstrap 4.

This section is an introduction of the Bootstrap Grid system with taking Flexbox into consideration as Bootstrap 4 is now using Flexbox as the default display system for the grid layout that brings many new and powerful features to how you can build your website layouts using the Bootstrap 4 grid.

Flexbox is a CSS 3 display system that aims to make it easy and straightforward to create layouts for dynamic or unknown screen sizes by allowing the container to have more control over the size of elements and then adapt to different viewports.

Without further introductions let’s create and decipher a simple page layout using Bootstrap 4 grid system.

First, you need to create an HTML page and link the Bootstrap 4 assets. You can simply use this template from the official Bootstrap 4 docs

<!doctype html><htmllang="en"><head><!-- Required meta tags --><metacharset="utf-8"><metaname="viewport"content="width=device-width, initial-scale=1, shrink-to-fit=no"><!-- Bootstrap CSS --><linkrel="stylesheet"href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm"crossorigin="anonymous"><title>BS 4 Flexbox Examples</title></head><body>    Add Content Here    <!-- Optional JavaScript --><!-- jQuery first, then Popper.js, then Bootstrap JS --><script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN"crossorigin="anonymous"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js"integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q"crossorigin="anonymous"></script><script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"integrity="sha384-JZR6Spejh4U02d8jOt6vLEHfe/JQGiRRSQQxSfFWpi1MquVdAyjUar5+76PVCmYl"crossorigin="anonymous"></script></body></html>

In order to create a grid, you’ll have to use some predefined BootStrap classes (.container, .row, col-*-*)

The grid should have a container, rows and columns.

The container is simply a <div> with the .container or .container-fluid classes. Why do you need a container and what is the difference between those two classes?

The container simply provides a width or a maximal width for all the other elements of the grid. For the difference .container allows you to create fixed-width container and .container-fluid allows you to create a full 100% container.

Rows provide home for columns. The number of rows can theoretically be unlimited.

Columns are what make the cells for the grid system. Each row can only take up to 12 columns (each column spans 1/12 of the available width). Practically a column spans more than one unit but there is one important rule ALL COLUMNS SHOULD ADD UP TO 12

To create a column you simply use a <div> with the the class(es) col-*-*

The first star for the screen breakpoint (xs, sm, md, lg, xl) and the second star for column size (1 .. 12).

<divclass="row"><divclass="col-sm-1 first-column">.col-sm-1</p></div>    ...    <divclass="col-sm-1 second-column">.col-sm-1</p></div></div>

See this code pen

Now let’s create a second row with two columns

<divclass="row"><divclass="col-sm-6 first-column">.col-sm-6</p></div><divclass="col-sm-6 second-column">.col-sm-6</p></div></div>

Note that .col-sm-6 + .col-sm-6 === .col-sm-12

Also note that you don’t need to explicitly add upper breakpoint classes i.e col-md-6 to col-xl-6 because .col-sm-6 means the size of the column should be 6 units from the small breakpoint and up

Next let’s add a third row with three columns

The first column spans two units, the second spans three units and the third spans the remaining 7 units. All colmuns sized add up to 12

.col-sm-2 + .col-sm-3 + .col-sm-7 === .col-sm-12

If you have previously used Bootstrap before version 4 you should have be familiar with all these concepts so what the new features Bootstrap 4 bring?

If you need to create a layout with automatic width columns you simply need to use .col-* or just .col without specifying the size and Bootstrap will take care of equally dividing the available width among those columns

<divclass="row"><divclass="col first-column"></div><divclass="col second-column"></div><divclass="col first-column"></div></div>

Now if you add a bunch of text to each column in order to chaine their heights you are going to get something like

As can be seen, unlike Bootstrap 3 all columns have the same height disregarding their contents which gives a better sense of a grid system.

Bootstrap 4 Flex Utilities

Bootstrap 4 by default uses Flexbox but it also provides a set of class utilities that allow you to work with Flexbox without resorting to custom CSS.

If you want to make a div element a flex container you can simply add the .d-flex class to a <div>

<div >This is now a flex container</div>

Or you can instead use d-inline-flex to create a inline flex container.

These two classes have also responsive versions i.e you can use d-d-*-flex and d-*-inline-flex where the start can be one of these breakpoints values xs, sm, md, lg and xl.

One important aspect of Flexbox is the ability to easily set the direction of items inside a flex container.

By default the direction is horizontal from left to right but can be set to be horizontal but from right to left with .flex-row-reverse or set it to be from left to right again with .flex-row (the default).

You can also use the .flex-column class to set a vertical direction from top to bottom, or the .flex-column-reverse class to change the vertical direction from bottom to top.

See the other available classes to control flex properties from the docs.

Bootstrap 4 Display Utilities

Bootstrap 4 provides a set of utilities that make it easy to set the display property of elements responsively i.e you can change the display property for specific breakpoints or screen sizes. See the docs for more details

Quickly and responsively toggle the display value of components and more with our display utilities. Includes support for some of the more common values, as well as some extras for controlling display when printing.

Simply use .d-{type} for the xs breakpoint or .d-{breakpoint}-{type} for sm, md, lg, and xl where type can be one of these display types

  • none
  • inline
  • inline-block
  • block
  • table
  • table-cell
  • table-row
  • flex
  • inline-flex

Summary

In this section, we’ve seen the grid layout in Bootstrap 4. Bootstrap has always been a powerful CSS framework for developers building their websites without a CSS designer in the team and now with the new features such as the default support for Flexbox you have great tools to build responsive layouts without being a CSS expert.
