pnpm link

Алиасы: ln

Делает текущий локальный пакет доступным для всей системы или в другом расположении.

pnpm link <название или путь к папке>
pnpm link --global
pnpm link --global <название-пакета>

Опции

--dir <название или путь до папки>, -C

  • По умолчанию: Текущая рабочая папка
  • Тип: Путь в виде строки

Изменяет расположение ссылки на <название или путь до папки>.

Связывает пакет из папки <dir> с node_modules пакета, из которого вы выполняете эту команду или указываете с помощью параметра --dir.

For example, if you are inside ~/projects/foo and you execute pnpm link --dir ../bar, then foo will be linked to bar/node_modules/foo.

Links package from location where this command was executed or specified via --dir option to global node_modules, so it can be referred from another package with pnpm link --global <pkg>. Also if the package has a bin field, then the package's binaries become available system-wide.

Связывает указанный пакет (<pkg>) из глобальных node_modules с node_modules пакета, из которого эта команда была выполнена или указана с помощью опции --dir.

pnpm link <dir> links the package from <dir> to the node_modules of the package where the command was executed. pnpm link --dir <dir> links the package from the current working directory to <dir>.

# The current directory is foo
pnpm link ../bar

- foo
- node_modules
- bar -> ../../bar
- bar

# The current directory is bar
pnpm link --dir ../foo

- foo
- node_modules
- bar -> ../../bar
- bar

Use Cases

Replace an installed package with a local version of it

Let's say you have a project that uses foo package. You want to make changes to foo and test them in your project. In this scenario, you can use pnpm link to link the local version of foo to your project, while the package.json won't be modified.

cd ~/projects/foo
pnpm install # install dependencies of foo
pnpm link --global # link foo globally
cd ~/projects/my-project
pnpm link --global foo # link foo to my-project

You can also link a package from a directory to another directory, without using the global node_modules folder:

cd ~/projects/foo
pnpm install # install dependencies of foo
cd ~/projects/my-project
pnpm link ~/projects/foo # link foo to my-project

Add a binary globally

If you are developing a package that has a binary, for example, a CLI tool, you can use pnpm link --global to make the binary available system-wide. This is the same as using pnpm install -g foo, but it will use the local version of foo instead of downloading it from the registry.

Remember that the binary will be available only if the package has a bin field in its package.json.

cd ~/projects/foo
pnpm install # install dependencies of foo
pnpm link --global # link foo globally

When you use pnpm link, the linked package is symlinked from the source code. You can modify the source code of the linked package, and the changes will be reflected in your project. With this method pnpm will not install the dependencies of the linked package, you will have to install them manually in the source code. This may be usefull when you have to use a specific package manager for the linked package, for example, if you want to use npm for the linked package, but pnpm for your project.

When you use the file: protocol in dependencies, the linked package is hard-linked to your project node_modules, you can modify the source code of the linked package, and the changes will be reflected in your project. With this method pnpm will also install the dependencies of the linked package, overriding the node_modules of the linked package.

инфо

When dealing with peer dependencies it is recommended to use the file: protocol. It better resolves the peer dependencies from the project dependencies, ensuring that the linked dependency correctly uses the versions of the dependencies specified in your main project, leading to more consistent and expected behaviors.
