How to Install Yarn on MacOS

Yarn is a package manager for for node.js applications. It allows you to create new packages (peace of code to do specific task) and share with the community.

It provides a command line interface to easy to install, update and manage packages for a Node application. This tutorial will help you to install yarn on macOS systems.

Install Yarn on macOS

Choose one of the below given methods to install Yarn on macOS system. All the methods are secure and easy to follow.

Method 1 – Using Homebrew

You can install Yarn using the Homebrew package manager on macOS system. Homebrew is an package manager for macOS operating system provides easier way to install and manage packages on your system.

To install Yarn on macOS, open a terminal and type:

Make sure you have installed Homebrew on your macOS system.

Method 2 – Using Shell Script

Another way to easily install Yarn pon macOS. This is a shell script provided officially for installing Yarn on different Unix/Linux operating systems.

You can install Yarn by running the following code in your terminal:

The script will verify the GPG signature first before the installation. So it is also secure way to install Yarn on macOS systems.

Check Yarn Version

Once the Yarn installation completed, execute the following command to verify yarn version.

Using Yarn

As of now, your have successfully install Yarn on macOS system. Let’s explore some basic uses of Yarn command line.

1. Starting a new project

Use yarn init under a empty folder to create new project.

The command will go through an interactive session asking few questions. Input the required values and press Enter. This will generate a package.json file in current directory.

2. Adding a dependency

Use yarn add command to install new dependency to your existing application. You need to specify package name to add. It will also make a entry in package.json as dependency.

Also you can specify package version or tag to select correct package version instead of latest version.

3. Upgrading a dependency

Use yarn upgrade command to upgrade already installed packages in your application.

You can also specify version or tag name to upgrade to specific versions.

4. Removing a dependency

If any of package is not more required, remove it from your application.

5. Installing dependencies

This will install all the packages dependencies defined in package.json file.

yarn install is the default action of yarn command without passing any subcommand.

Conclusion

This tutorial explained you to installing yarn on macOS system. Also explored the details to work with yarn package manager.

2 — Installation

Migrating from Yarn 1

We’ve been compiling helpful advice when porting over from Yarn 1 on the following Migration Guide. Give it a look and contribute to it if you see things that aren’t covered yet! Make sure to consult the PnP Compatibility Table and enable the node-modules plugin if required!

About global installs

Using a single package manager across your system has always been a problem. To be stable, installs need to be run with the same package manager version across environments, otherwise there’s a risk we introduce accidental breaking changes between versions — after all, that’s why the concept of lockfile was introduced in the first place! And with Yarn being in a sense your very first project dependency, it should make sense to «lock it» as well.

For this reason, Yarn 2 and later are meant to be managed on a by-project basis. Don’t worry, little will change! Just make sure to first install the global Yarn binary that we will use to spawn the local ones:

Once you’ve followed the instructions (running yarn —version from your home directory should yield something like 1.22.0 ), go to the next section to see how to actually enable Yarn 2 on your project.

You’ve probably remarked the global Yarn is from the «Classic» line (1.x). This is expected! One extra perk of this system is that projects configured for Yarn 1 will keep using it instead of suddenly having to migrate to the 2.x configuration format. We wouldn’t have had to do this if Yarn had been «project locked» from the beginning, but hindsight is 20/20 😉

1. Install the Yarn global binary to its latest version:

«Berry» is the codename for all versions of Yarn from 2 onwards: 2.x, 3.x, etc. It’s also the name of our repository!

Updating to the latest versions

Should you later want to update Yarn to the latest version, just run:

Yarn will then download the most recent binary from our website, and install it in your projects. Don’t forget to run a new install to update your artifacts, and to commit the results!

Installing the latest build fresh from master

From time to time even the most recent releases aren’t enough, and you then will want to try out the very latest master to check if a bug has been fixed. This has become very simple with Yarn 2! Just run the following command:

Similarly, specific PRs can be installed using the —branch flag:

Yarn 2 — Устанавливаем и разбираемся

Знакомство

Yarn 2 (Berry) — это новый выпуск революционного и хорошо зарекомендовавшего себя менеджера пакетов Yarn, включающий в себя такие особенности, как: Plug’n’Play, возможность расширения модульного API, оффлайн-кэш и улучшенную поддержку рабочих пространств.

Plug’n’Play

Yarn PnP — это новая функция, которая по умолчанию включена в Yarn 2. PnP избавляет проекты от папки node_modules в пользу файла .pnp.js.

Файл .pnp.js сопоставляет все пакеты, установленные в проекте, с тем местом, где Yarn разместил их на вашем диске. Это избавляет от большого количества операций ввода-вывода при генерации node_modules, обеспечивая более быструю и надёжную установку.

В новой документации Yarn подробно рассказывается о недостатках node_modules, как структуры папок, и объясняется, почему необходим новый взгляд на управление зависимостями.

Монорепозитории

Не зависимо от того, являетесь бы поклонником монорепозиториев или нет, чтобы обеспечить качественное управление большими проектами и сложными рабочими процессами, потребуется хороший набор инструментов.

Популярным рецептом настойки JavaScript монорепозитория является комбинация рабочих пространств Yarn и использование Lerna в качестве менеджера проектов.

Хорошая новость заключается в том, что теперь Yarn может одновременно выполнять функции как менеджера пакетов, так и менеджера проектов, пытаясь обеспечить положительный опыт работы в этом аспекте.

Модульная архитектура, плагины

Сделав важный шаг вперед, Yarn 2 был переработан в пользу нового модульного API, расширяемого при помощью плагинов. В настоящее время большинство функций уже реализовано с их помощью — даже yarn add и yarn install являются предустановленными плагинами!

Вы можете сами написать плагин для Yarn, а чтобы дать вам представление об этом процессе, разработчики Yarn создали плагин TypeScript, который будет автоматически добавлять соответствующие @types/packages каждый раз, когда вы запускаете yarn add .

Как начать работу?

Установка

Yarn придерживается стратегии глобальной установки первой версии, а уже затем переключения на вторую для конкретного проекта.

Сначала установим глобальный Yarn, который мы будем использовать для создания локальных экземпляров:

Выполнив данную инструкцию (запуск yarn —version должен вывести что-то вроде 1.22.x ), перейдём к созданию каталога для запуска нового проекта:

“Berry” — кодовое имя релизной ветки Yarn 2.
Изменим версию Yarn конкретно для каталога my-app :

После выполнения данной команды установка будет завершена, и можно переходить к установке зависимостей!

Добавление зависимостей

Общие команды управления остались теми же, что и в предыдущих версиях:

yarn init — инициализация проекта

[—dev] — добавление пакета

Также, вы можете увидеть некоторые изменения консольного интерфейса в новой версии Yarn:

каждый набор связанных задач, выполняемых в процессе установки, сгруппирован;

почти все сообщения имеют собственные коды ошибок, которые можно найти в документации;

цвета теперь используются только для обозначения важных частей каждого сообщения.

Установка React.js с Yarn-плагином TypeScript

Далеко не все пакеты поставляются с собственными определениями типов, но уже нет поводов для волнения, ведь там, где их нет, Yarn возьмёт работу на себя.

Перед выполнением операцией ниже, следует установить Yarn Berry для рабочей директории и убрать детей от экрана.

Инициализируем package.json и установим плагин TypeScript:

Проведем установку библиотеки React:

Зависимости @types/ были успешно установлены!

package.json

Что в итоге

Ветка Yarn 1.x (Classic) уже официально перешла в статус поддержки, предполагающей только исправление уязвимостей.

Все новые функции будут разрабатываться исключительно для Yarn 2, версия которого будет распространяться через yarn set version .

Для React Native всё таки придётся подключать node modules.

Если Yarn не подружится с вашей IDE, нужно будет кое-что установить. Не скучайте!
