Working with Packages

As we are using yarn for managing packages, here are some helpful tips for whenever you need to work with them.

Install packages

To ensure you have the right version of dependencies, run this command after cloning or switching branches.

> yarn

This will restore the versions stored in the lock file to the node_modules folder.

Add new packages

Rather than updating the package.json explicitly, you can install new dependencies via the yarn command line:

# adds the package to the dependencies list
> yarn add [package-name]
# adds the package to the devDependencies list
> yarn add [package-name] --dev

Updating packages

To see which packages have newer versions available:

> yarn outdated

To upgrade a package:

> yarn upgrade [package-name]@[version]

You don't need to specify the version here, but this ensures the change is reflected in the package.json file.

Removing packages

To remove any packages that are no longer needed:

> yarn remove [package-name]
