Uninstall a Package with npm – onlinecode
In this post, we will give you information about Uninstall a Package with npm – onlinecode. Here we will give you detail about Uninstall a Package with npm – onlinecode And how to use it also give you a demo for it if it is necessary.
npm makes it easy to uninstall packages. Running
npm uninstall <package>
uninstalls the given package. For example, when you run npm uninstall mongoose
from the onlinecode GitHub repo, npm prints the
below output:
$ npm uninstall mongoose
removed 22 packages and audited 1204 packages in 3.311s
found 0 vulnerabilities
$
After running npm uninstall mongoose
, the node_modules
directory no longer contains Mongoose, and calling
require('mongoose')
will fail.
$ ls -l node_modules/ | grep "mongoose$"
$
$ node -e "require('mongoose')"
internal/modules/cjs/loader.js:800
throw err;
^
Error: Cannot find module 'mongoose'
$
What Does npm uninstall Do?
npm uninstall
does a little more than just rm -rf ./node_modules/mongoose
. Although deleting the node_modules/mongoose
directory works, it leaves Mongoose’s dependencies in node_modules
.
Notice that the output of npm uninstall
says it removed 22 packages:
$ npm uninstall mongoose
removed 22 packages and audited 1204 packages in 3.311s
found 0 vulnerabilities
$
Those are packages that Mongoose depends on, but no other package depends on, so they’re safe to remove.
The --no-save
Flag
npm uninstall
also removes the package from your package.json
, which means subsequent
npm install
won’t install that package. This is a convenience that saves you an extra step when you want to
permanently remove a package from a JavaScript project.
However, there are cases when you may want to uninstall a package without modifying package.json
. For example,
you may want to test that your app still works even if a certain package is missing. In that case, you can use
npm uninstall --no-save
:
$ npm uninstall mongoose --no-save
removed 22 packages and audited 1204 packages in 3.311s
found 0 vulnerabilities
$
$ cat package.json | grep "mongoose"
"mongoose": "5.x",
"mongoose-beautiful-unique-validation": "7.x",
$
