pnpm run

Aliases: run-script

Runs a script defined in the package's manifest file.

Examples

Let's say you have a watch script configured in your package.json, like so:

"scripts": {
"watch": "webpack --watch"
}

You can now run that script by using pnpm run watch! Simple, right? Otra cosa a tener en cuenta para aquellos a los que les gusta ahorrar pulsaciones de teclas y tiempo es que todos los scripts tienen un alias como comandos pnpm, por lo que, en 煤ltima instancia, pnpm watch es solo una abreviatura de pnpm run watch (S脫LO para scripts que no comparten el mismo nombre que los comandos pnpm ya existentes).

Detalles

Adem谩s del PATH preexistente del shell, pnpm run incluye node_modules/.bin en el PATH proporcionado a scripts. Esto significa que siempre que tenga un paquete instalado, puede usarlo en un script como un comando normal. Por ejemplo, si tiene instalado eslint, puede escribir un script as铆:

"lint": "eslint src --fix"

And even though eslint is not installed globally in your shell, it will run.

For workspaces, <workspace root>/node_modules/.bin is also added to the PATH, so if a tool is installed in the workspace root, it may be called in any workspace package's scripts.

Differences with npm run

By default, pnpm doesn't run arbitrary pre and post hooks for user-defined scripts (such as prestart). This behavior, inherited from npm, caused scripts to be implicit rather than explicit, obfuscating the execution flow. It also led to surprising executions with pnpm serve also running pnpm preserve.

If for some reason you need the pre/post scripts behavior of npm, use the enable-pre-post-scripts option.

Environment

There are some environment variables that pnpm automatically creates for the executed scripts. These environment variables may be used to get contextual information about the running process.

These are the environment variables created by pnpm:

  • npm_command - contains the name of the executed command. If the executed command is pnpm run, then the value of this variable will be "run-script".

Options

Any options for the run command should be listed before the script's name. Options listed after the script's name are passed to the executed script.

All these will run pnpm CLI with the --silent option:

pnpm run --silent watch
pnpm --silent run watch
pnpm --silent watch

Any arguments after the command's name are added to the executed script. So if watch runs webpack --watch, then this command:

pnpm run watch --no-color

will run:

webpack --watch --no-color

script-shell

  • Default: null
  • Type: path

The shell to use for scripts run with the pnpm run command.

For instance, to force usage of Git Bash on Windows:

pnpm config set script-shell "C:\\Program Files\\git\\bin\\bash.exe"

shell-emulator

  • Default: false
  • Type: Boolean

When true, pnpm will use a JavaScript implementation of a bash-like shell to execute scripts.

This option simplifies cross-platform scripting. For instance, by default, the next script will fail on non-POSIX-compliant systems:

"scripts": {
"test": "NODE_ENV=test node test.js"
}

But if the shell-emulator setting is set to true, it will work on all platforms.

--recursive, -r

This runs an arbitrary command from each package's "scripts" object. If a package doesn't have the command, it is skipped. If none of the packages have the command, the command fails.

--if-present

You can use the --if-present flag to avoid exiting with a non-zero exit code when the script is undefined. This lets you run potentially undefined scripts without breaking the execution chain.

--parallel

Completely disregard concurrency and topological sorting, running a given script immediately in all matching packages with prefixed streaming output. This is the preferred flag for long-running processes over many packages, for instance, a lengthy build process.

--stream

Stream output from child processes immediately, prefixed with the originating package directory. This allows output from different packages to be interleaved.

--aggregate-output

Aggregate output from child processes that are run in parallel, and only print output when the child process is finished. It makes reading large logs after running pnpm -r <command> with --parallel or with --workspace-concurrency=<number> much easier (especially on CI). Only --reporter=append-only is supported.

enable-pre-post-scripts

  • Default: false
  • Type: Boolean

When true, pnpm will run any pre/post scripts automatically. So running pnpm foo will be like running pnpm prefoo && pnpm foo && pnpm postfoo.

--resume-from <package_name>

Added in: v7.22.0

Resume execution from a particular project. This can be useful if you are working with a large workspace and you want to restart a build at a particular project without running through all of the projects that precede it in the build order.

--filter <package_selector>
