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. In addition, it is open source and it has the protection of a giant like Facebook what guarantees us solidity and robustness of the project. Some of its characteristics are the following:

• Fast: Yarn caches every package it has downloaded.
• Reliable: Using a detailed but concise lockfile format and a deterministic algorithm for install operations.
• Secure: Yarn uses checksums to verify the integrity of every installed package before its code is executed.

There are also other features such as its efficiency in the use of the network as well as offline mode. All this can be found on the Github site of Yarn.

Install Yarn on OpenSUSE 15.2

Unfortunately, Yarn is not present in the official distribution repositories. You can check this by running the following command

sudo zypper search yarn

You will get an output screen like the following:

Loading repository data...
Reading installed packages...
No matching items found.

So we have to use another method to perform the installation.

The easiest and recommended method is to use the compiled Linux binary that we can download via the curl command.

So, install the curl tool by running the following command:

sudo zypper in curl

After that, download and install Yarn

curl -o- -L https://yarnpkg.com/install.sh | bash

And to make Yarn available from any prompt location, run the following command:

source ~/.bashrc

Now you can use Yarn for whatever you want, for example, to check the installed version of Yarn

yarn -v
1.22.5

So, enjoy it.

Conclusion

Yarn is a great alternative to NPM to manage the dependencies of our web projects. So it becomes essential if we are web developers or we are learning in it.

• Adding Yarn Repository
• Installing Yarn with NPM
• Script installation of Yarn

We’ll see all these methods you can choose your desired one for installation purposes.

Step 1: Update Your System

First of all update your system to the latest one before going to install any package on your system. Type the below command in your terminal.

sudo apt udpate

Step 2: Install Yarn with Repository on Ubuntu 20.04

To install the Yarn with the repository on your system you have to add the repository first provided by the Yarn for Linux systems. Run the following command to import the GPG key for verification of Yarn package.

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

Then type the given command to enable the Yarn repository.

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

Now, update the system and install yarn with the given command. And press Y when prompted.

sudo apt update 
sudo apt install yarn

Output:

You’ll see the similar output.

So, let us start.

Install Yarn on FreeBSD 12

For this tutorial, you must have sudo enabled, so this is the first step.

How to enable sudo on FreeBSD 12?

After you can use sudo, you can continue.

The FreeBSD 12 repositories are quite large, so we will first look for yarn in them.

Open a terminal and run the following:

:~$ sudo pkg search yarn
yarn-1.19.1                    Package manager for node, alternative to npm
yarn-node10-1.19.1             Package manager for node, alternative to npm
yarn-node12-1.19.1             Package manager for node, alternative to npm
yarn-node8-1.19.1              Package manager for node, alternative to npm

As you can see in the picture, yarn is in the official repositories. And also, they have several versions according to the version of NodeJS we have installed.

However, to install it, just use the following command:

:~$ sudo pkg install yarn
Updating FreeBSD repository catalogue...
FreeBSD repository is up to date.
All repositories are up to date.
The following 6 package(s) will be affected (of 0 checked):

New packages to be INSTALLED:
	yarn: 1.19.1
	node: 13.3.0
	libnghttp2: 1.40.0
	c-ares: 1.15.0_1
	libuv: 1.34.0
	icu: 65.1,1

Number of packages to be installed: 6

The process will require 92 MiB more space.
19 MiB to be downloaded.

Proceed with this action? [y/N]:

Once it is installed, you can check the installed version.

:~$ yarn --version

This indicates that yarn is ready for action.

Basic use of Yarn

Now we will look at some basic steps in the use of yarn. I’m going to create a sample project, and for that I’ll first create a new dedicated folder.

:~$ mkdir project

Now I’ll access it:

cd project/

And within it, I initiate the yarn project. This will make me ask some questions about the configuration of the project. Nothing complicated.

:~$ yarn init
yarn init v1.19.1
question name (project): Example
question version (1.0.0): 
question description: This is an example
question entry point (index.js): 
question repository url: https://www.osradar.com/
question author: Angelo
question license (MIT): 
question private: no
success Saved package.json
Done in 34.27s.

If you want to add a new dependency, just use the following command:

:~$ yarn add [name]

Or to eliminate it:

:~$ yarn remove [name]

And from the project folder, we can install the rooms:

:~$ yarn

And so we can continue with the installation.

Conclusion

Yarn is a fantastic tool for Javascript developers and thus makes it easier to create functional web applications. Now you know how to install it on FreeBSD 12.

Install Yarn on Debian 10

The installation of Yarn becomes quite easy, thanks to the fact that we have been given a package repository for Debian. This not only makes the installation easy but also allows us to keep it updated.

However, there are some necessary packages to be installed:

:~$ sudo apt install curl gpg

As you can see, I’m using sudo. If you don’t have it enabled you can do it with the following tutorial:

How to enable sudo on Debian 10?

Now we can execute the following command to add the GPG key to the repository:

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

And then, it’s time to add the Yarn repository for Debian 10.

:~$ 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

After the repository and its GPG key have been correctly added, the APT cache must be refreshed:

:~$ sudo apt update

And finally, install Yarn on Debian 10 with the following command:

:~$ sudo apt install yarn 

As you can see in the picture, one dependency of Yarn is NodeJS and NPM. In case you already have it installed, you can install yarn with the following command:

:~$ sudo apt-get install --no-install-recommends yarn

Finally, you can check that everything went well, by showing Yarn’s version.

:~$ yarn -v

And that’s it, Yarn is ready for the job.

Conclusion

Yarn is a great alternative to NPM to manage the dependencies of our web projects. So it becomes essential if we are web developers or we are learning in it.

Yarn is a new JavaScript package installer and dependency manager released by Facebook. Other companies such as Google have also collaborated. With yarn, the problems of library dependencies that a web project requires are solved. Normally, it’s done manually but it’s not optimal, that’s why Yarn solves this problem.

Yarn’s performance is quite similar to that of NPM which is its direct competitor. However, the performance is somewhat superior at Yarn. Some of Yarn’s key features are security and dependency resolution speed.

Install Yarn on OpenSUSE 15.1

Yarn requires NodeJS to work. So the first step is to install it. So I recommend you to read our post about NodeJS on OpenSUSE.

How to install NodeJS on OpenSUSE 15.1?

If we use zypper to search for the yarn package, we will notice that it is not in the official repositories.

:~$ sudo zypper search yarn

However, we can use a script to install the latest available version of Yarn.

First, make sure you have curl installed.

:~$ sudo zypper in curl

Then, run this command which will download and install the latest available version of yarn.

:~$ curl -o- -L https://yarnpkg.com/install.sh | bash

As you can see at the end of the screen output, you just have to open a new terminal session so you can use yarn without problems.

Once you’ve done that, you can show the installed version and you can use it:

:~$ yarn -v

So, enjoy it.

Conclusion

If you are a web developer you need to know and use many tools to do so. That’s why it’s yarn to excel in the management of dependencies and their security. So today you have learned how to install it on OpenSUSE 15.1.
