Yarn - remove package best practices

If you run yarn remove [package] it will remove the package from node_modules and also from the yarn.lock file.

If you manually delete from package.json and then run yarn install, the deleted package is not installed and the yarn.lock file is not updated.

When you remove with Yarn by running the first approach (#1).

yarn remove [package]

Both your entries from lockfile and package.json are removed. Look out for this message in the terminal.

$ yarn remove x2js
yarn remove v0.27.5
[1/2] Removing module x2js...
[2/2] Regenerating lockfile and installing missing dependencies...
success Uninstalled packages.
Done in 2.34s.

The new file won't have the package.

If you follow the second (#2) approach and delete it from package.json and run:

yarn install

There will we no effect on your lockfile.

So it is better to remove packages using the first approach (#1).

If you have deleted some package(s) directly from package.json and don't know what was there then your lockfile is not up to date.

I would suggest you delete the yarn.lock file . and then run yarn install. This way, you will get an updated yarn.lock file.
