Установка yarn в Ubuntu
В наши дни платформа Node.js набирает всё большей популярности. Кроме пакетного менеджера по умолчанию под названием npm для этой платформы существует другой улучшенный пакетный менеджер под названием yarn. Он позволяет устанавливать, удалять и обновлять пакеты.
Yarn полностью совместим с npm, поэтому этот пакетный менеджер можно использовать вместе с npm. Тут используется тот же файл конфигурации package.json. В сегодняшней статье мы рассмотрим как выполняется установка Yarn Ubuntu на примере версии дистрибутива 20.04.
Установка yarn в Ubuntu
Установить программу в Ubuntu достаточно просто. Правда её нет в официальных репозиториях, поэтому вам придется добавить репозиторий разработчиков. Для этого вам понадобится утилита curl. Установите её, если она ещё не установлена:
sudo apt install curl
Теперь можно импортировать GPG ключ репозитория. Для этого выполните:
После добавления ключа добавьте репозиторий в файл /etc/apt/sources.list.d/yarn.list. Это можно сделать вручную или с помощью такой команды:
echo «deb https://dl.yarnpkg.com/debian/ stable main» | sudo tee /etc/apt/sources.list.d/yarn.list
Затем обновите списки пакетов:
sudo apt update
И останется только установить yarn:
sudo apt install yarn
Посмотреть версию установленной программы можно такой командой:
Чтобы создать новый проект перейдите в папку с проектом и выполните такую команду:
yarn init имя_проекта
Во время создания проекта пакетный менеджер сгенерирует package.json и для его генерации вам надо будет ответить на ряд вопросов. Хотя можно оставить все значения по умолчанию. Для установки какого-либо пакета следует использовать команду add. Синтаксис у неё такой:
$ yarn add имя_пакета @ версия
Например, для установки пакета vue выполните команду:
yarn add vue@latest
Когда пакет будет установлен, вы можете его использовать. Можете посмотреть содержимое файла package.json:
Для удаления пакетов используйте команду remove:
$ yarn remove имя_пакета
Чтобы обновить все установленные зависимости используйте команду upgrade:
Если вы скачали уже готовый проект, для установки всех его зависимостей, прописанных в package.json используйте такую команду:
Теперь вы знаете как выполняется установка Yarn Ubuntu, что из себя представляет этот пакетный менеджер, а также как с помощью него управлять пакетами.

Why is Yarn faster than NPM?
There is no doubt that Yarn works much more efficiently during installation. The NPM first tracks all branches of dependencies and then receives the required packages. But Yarn doesn’t. It first searches for dependencies in the registry. It then receives the downloaded packages from the cache directory. If it finds a dependency, it uses it, if not, it downloads it as tar. Finally, it copies all packets from the global cache to the node_modules directory.
All these operations are performed in parallel to increase the installation speed. Using a global cache is much faster than downloading all the packages every time we need them. Yarn also has an added advantage: it allows Yarn to work offline!
Conclusion

Yarn is a tool for managing, updating, and sharing your Java code. Yarn works through node.js helping to track libraries, dependencies, and even enables you to share solutions with other developers.
In this tutorial learn how to install Yarn on Ubuntu 18.04.
Option 1: Install Yarn Using Ubuntu Repositories
Yarn developers maintain a repository for installing directly to Ubuntu that simplifies the installation process. For detailed inustrctions, follow the steps below.
Step 1: Configure the Yarn Repository
Open a terminal window, and add the GPG key:
The GPG key ensures that you’re installing authentic software. Next, add the Yarn repository:
This adds the Yarn repository to your master repository list.
Now, your standard package manager can access and manage Yarn.
Step 2: Install Yarn
Update your local repository listings:
This command installs Yarn on your system. If you don’t already have node.js installed, your package manager will install it for you.
To verify a successful installation, display the Yarn version:
Option 2: Install Yarn Using NPM
Npm stands for Node Package Manager. It’s commonly used to develop and share javascript code.
1. Start by listing the version to check if NPM in installed:
If you don’t have npm, install it by running the following command:
2. To install Yarn with npm:
Upon installing, the output should notify you which version of Yarn has been installed. In the example above, it is version 1.17.3.
In many ways, Yarn is very similar to npm. Yarn adds a yarn.lock file, which restricts packages to a specific version. This is especially helpful for maintaining a consistent development environment.
Note: If you want to learn what are the differences between Yarn and NPM, check our article yarn vs. npm.
How to Upgrade Yarn Version
To upgrade Yarn to the latest version, run the following command from the terminal:
The system will download the Yarn tarball and install the latest version. The image below displays the output you can expect.
Basic Yarn Usage
Now that you have Yarn installed, the sections below dive into how to use basic Yarn commands.
Create a New Yarn Project
To create a new project, enter the following:
The system will launch a script that will ask questions about the project. Press enter to use the default for each entry.
Add a Dependency to Your Project
A package (sometimes called a module) is a self-contained piece of code. It holds all the components needed to run or work on the code. A package may rely on other packages. These are called dependencies, because the package needs them to function.
To Install a dependency, enter the following:
The command above adds the latest version of the named package.
To install a specific version, enter the following:
If the package has a tag, simply substitute [version] for [tag]:
This process automatically updates the package.json file. It also updates the yarn.lock file. This ensures that everyone using the package is working with the same software.
Upgrade a Yarn Dependency
To upgrade a dependency, use the command:
Like the add command, Yarn can be upgraded by version or tag:
Remove a Yarn Dependency
Remove a dependency by entering the command:
Install Additional Dependencies
Yarn works through the package.json configuration file. This file keeps a record of all the packages required for your project. When you’re working on a code project, you may add a package that has additional dependencies.
To install these dependencies, enter the following:
This will update and load all the dependencies for your project configuration.
Yarn is set up to allow multiple users, and to control versions. In some cases, a different developer may add a package to the master package.json file. If that’s the case, you should run the yarn install command as soon as possible. This will update your version of the project, and ensure that you’re working in the same environment.
Note: If you need to use Yarn on Windows, refer to our installation guide How to Install Yarn on Windows
You should now have a good understanding of how to install Yarn on an Ubuntu system. We also covered basic commands for working with Yarn projects.
