    Run an npm script in each package that contains that script

    Install lerna for access to the lerna CLI.


    $ lerna run <script> -- [..args] # runs npm run my-script in all packages that have it 
    $ lerna run test
    $ lerna run build
    # watch all packages and transpile on change, streaming prefixed output 
    $ lerna run --parallel watch

    Run an npm script in each package that contains that script. A double-dash (--) is necessary to pass dashed arguments to the script execution.


    lerna run respects the --concurrency, --scope, and --ignore flags (see Filter Flags).

    $ lerna run --scope my-component test

    --npm-client <client>

    Must be an executable that knows how to run npm lifecycle scripts. The default --npm-client is npm.

    $ lerna run build --npm-client=yarn

    May also be configured in lerna.json:

      "command": {
        "run": {
          "npmClient": "yarn"


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

    $ lerna run watch --stream


    Similar to --stream, but completely disregards concurrency and topological sorting, running a given command or script immediately in all matching packages with prefixed streaming output. This is the preferred flag for long-running processes such as npm run watch run over many packages.

    $ lerna run watch --parallel

    Note: It is advised to constrain the scope of this command when using the --parallel flag, as spawning dozens of subprocesses may be harmful to your shell's equanimity (or maximum file descriptor limit, for example). YMMV


    # Run an npm script in all packages that contain it, ignoring non-zero (error) exit codes 
    $ lerna run --no-bail test

    By default, lerna run will exit with an error if any script run returns a non-zero exit code. Pass --no-bail to disable this behavior, running the script in all packages that contain it regardless of exit code.


    Disable package name prefixing when output is streaming (--stream or --parallel). This option can be useful when piping results to other processes, such as editor plugins.
