Using Limit() With Mongoose Queries

Using limit() with Mongoose Queries

In this post, we will give you information about Using limit() with Mongoose Queries. Here we will give you detail about Using limit() with Mongoose Queries And how to use it also give you a demo for it if it is necessary.

Mongoose’s limit option allows you to limit the amount of results from the query. The easiest way to set the limit option is using the limit() method as follows.

const mongoose = require('mongoose');

const testSchema = new mongoose.Schema({
  name: String
});

const Test = mongoose.model('Test', testSchema);

async function run() {
  await mongoose.connect('mongodb://localhost:27017');
  for (let i = 0; i < 10; i++) {
    await Test.create({
      name: 'Test' + i
    });
  }
  console.log(await Test.find().limit(2)); // returns a maximum of two documents
}
run();

Sorting forUsing limit() with Mongoose Queries

We recommend always using limit() with sort().
If you don’t specify sort(), the MongoDB server doesn’t guarantee you’ll get the results back in any particular order.
The MongoDB server applies sortbeforelimit, so MongoDB will sort the full result set and give you the first limit results in order.

await Test.find().limit(5); // returns a maximum of 5 documents, could be in any order
await Test.find().sort({ createdAt: -1 }).limit(5); // returns the first 5 documents created

Using callbacks for Using limit() with Mongoose Queries

If you are using callbacks, make sure to call limit()before passing in a callback. Failure to do so will result in the query executing without a limit as seen here.

A mongoose is a small, carnivorous mammal that is found in Africa, Asia, and southern Europe. They are known for their ability to kill venomous snakes, and they have been used for centuries to control snake populations. Mongooses are also popular pets, but they can be difficult to care for and are not recommended for everyone.
