yarn init my_project

This command will ask you some questions. Press enter to accept the defaults or fill them with your answers.

This command will create a basic package.json file that contains the information you have provided.

You can modify this file any time you want.

Also, you can initiate a Yarn project in an existing directory on AlmaLinux 9. To do this, switch to the directory and run the following command:

yarn init

Add a Package with Yarn

To add a package as a dependency to your project you can use the following command:

yarn add [package_name]

With this command, you can install the package and any packages that it depends on. Also, it will update the project’s package.json and yarn.lock files.

If you use only the package name in the command, Yarn will install it in the latest version.

To install a specific version or tag, use the following command:

yarn add [package_name]@[version_or_tag]

Upgrade a Package with Yarn

Also, you can upgrade the packages with the following commands:

$ yarn upgrade
$ yarn upgrade [package_name]
$ yarn upgrade [package_name]@[version_or_tag]

If no package name is given, the command will update the project dependencies to their latest version according to the version range specified in the package.json file. Otherwise, only the specified packages are updated.
