How to Install Yarn on Ubuntu
Installing Yarn onto your Ubuntu system isn't a complex undertaking. All it entails is allowing the official Yarn repository, importing the repository GPG key, and downloading the package. The stable repository is constantly being maintained and boasts the latest edition.
You can enable the Yarn APT repository on your system and import the repository's GPG key by executing these commands:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.listCopyCopy
After enabling the repository, proceed by updating the list of packages and installing Yarn.
sudo apt updatesudo apt install yarnCopyCopy
To avoid installing Node.js after installing it through nvm, skip the installation by not using the aforementioned command.
sudo apt install --no-install-recommends yarnCopy
To confirm that Yarn has been installed successfully, print out the version of Yarn once the installation process is finished.
The end result will look similar to this:
The one displayed above may not match the version that is currently installed on your system.
With Yarn now installed on your Ubuntu device, you can begin utilizing it. Congrats on a successful installation!
Using Yarn on Ubuntu
Pondering that Yarn has been set up on your Ubuntu operating system, why not delve into a few of the frequently used Yarn codes?
Creating a new project
Begin by creating a folder specifically for your application and open the folder:
mkdir ~/my_project && cd ~/my_projectCopy
Make a new project by executing the command yarn init.
yarn init my_projectCopy
Answer a series of questions the command poses or agree with the defaults.
Yarn init v1.22.4 question name (vagrant): Linuxize question version (1.0.0): 0.0.1 question description: Testing Yarn question entry point (index.js): question repository URL: question author: Linuxize question license (MIT): question private: success Saved package.json Done in 20.18s. Copy
Upon finishing, the script produces a basic package.json file containing the data given. This file is accessible for modification whenever desired.
When adding an NPM package to your project dependencies, type in the package name following the command of yarn add.
yarn add [package_name]Copy
The above command will trigger an update to the files package.json and yarn.lock.
To install a particular version or tag of a package, you must use a different syntax instead of just providing the package name. The default behaviour of Yarn is to install the latest version when only the package name is given.
yarn add [package_name]@[version_or_tag]Copy
To update the packages, execute any of the subsequent instructions:
yarn upgradeyarn upgrade [package_name]yarn upgrade [package_name]@[version_or_tag]CopyCopyCopy
Without a package name, the command will alter the project's dependencies to their most recent version, as mentioned in the package.json file's version range. Alternatively, only the designated packages will be refreshed.
Employ the 'yarn remove' command and subsequently enter the package name to eliminate dependency.
yarn remove [package_name]Copy
To update both the project's package.json and yarn.lock files, execute the command that removes the package.
Installing all project dependencies
Execute the command to equip all requisite project dependencies mentioned in the package.json file:
Advantages of Using Yarn
Yarn is a popular package and dependency management tool developers use to build and manage their projects. It is compatible with various operating systems, including Ubuntu, a widely used Linux distribution. Here are some of the advantages of using yarn on Ubuntu:
Faster Installation: Yarn has a faster installation process than other package managers like NPM. It uses a caching mechanism that saves packages and dependencies locally, resulting in quicker installations and updates.
Enhanced Security: Yarn checks for package integrity by verifying the checksum of each package and its dependencies, ensuring that the packages are not tampered with or compromised.
Better Performance: Yarn parallelizes operations to optimize installation processes, making it faster than other package managers. It also reduces the number of network requests compared to NPM, resulting in faster builds and better performance.
Easy to Use: Yarn has a simple and easy-to-use interface that helps developers manage packages and dependencies efficiently. It also offers features like workspaces that allow developers to manage multiple projects simultaneously, making navigating and working in complex environments easy.
Compatibility: Yarn is compatible with NPM, meaning developers can use it alongside NPM to manage their projects, ensuring they are compatible with other developers' projects.
