How to Install Yarn in Ubuntu 18 04

Linux

Install yarn on ubuntu 18.04

Yarn is a Javascript dependency manager that stands out for being fast, secure and reliable. It is presented to us as the most solid alternative to NPM.Like npm, Yarn provides you a way to automate the process of installing, updating, configuring and removing packages retrieved from a global registry.It is an opensouce and  alternative that any other Nodejs package manager’s.

The advantage of Yarn is that it is faster as it caches every package it downloads so it doesn’t need to download it again. It also parallelizes operations to maximize resource utilization.

Step 1: Add yarn repo

First we will login the server with root user o any other user with sudo privileges.

Then open the terminal and add below GPG key.

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

Now add Yarn repository to source list

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sample output:

root@ubuntu18:~# curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
OK
root@ubuntu18:~# echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
deb https://dl.yarnpkg.com/debian/ stable main

Step 2: Install yarn

once repository is added then update apt cache

root@ubuntu18:~# apt update

If you are currently using Nodejs and NPM, then you can install yarn using below command.

root@ubuntu18:~# apt install --no-install-recommends yarn

if you are not using any nodejs and NPM then install with following command.

root@ubuntu18:~# apt install yarn

root@ubuntu18:~# apt install yarn
