$ sudo apt update
$ sudo apt install curl
$ curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add –
Now addition to the repository requires the following command:
$ echo “deb https://dl.yarnpkg.com/debian/ stable main” |
sudo tee /etc/apt/sources.list.d/yarn.list

$ sudo apt update && upgrade
$ sudo apt install yarn
Step 3: Verification
In order to verify that the version is recent one, the command below is utilized:
$ yarn –version
This command prints the version present in the system and thus depicts the number and the install is verified.

Queries about different features of the project will be displayed on the screen which can be specified by you or default values can be used instead.
The package.json file thus created for the project will give you a start for the project.
Addition and Up gradation of Dependencies
Firstly an npm package must be adjoined to the file created.
The Yarn add command is of value in order to add npm package to project dependencies as under:
$ yarn add [package_name]
Thus package.json file is updated. By default, the latest version is installed by Yarn if package name is added only. Updating to a version of your interest requires the command below:
$ yarn add [package_name]@[version_or_tag]
Erasing a Dependency
A certain dependency can be omitted using the following command:
$ yarn remove [package_name]
This will automatically update package.json and yarn.lock files of the project also.

$ yarn install
