npm-run-script

NPM-RUN-SCRIPT(1)														 NPM-RUN-SCRIPT(1)

NAME

       npm-run-script - Run arbitrary package scripts

SYNOPSIS

	 npm run-script <command> [--silent] [-- <args>...]

	 alias: npm run

DESCRIPTION

       This  runs  an  arbitrary  command  from  a  package's  "scripts" object.  If no "command" is provided, it will list the available scripts.
       run[-script] is used by the test, start, restart, and stop commands, but can be called directly, as well. When the scripts in  the  package
       are printed out, they're separated into lifecycle (test, start, restart) and directly-run scripts.

       As  of  `  https://blog.npmjs.org/post/98131109725/npm-2-0-0, you can use custom arguments when executing scripts. The special option -- is
       used by getopt https://goo.gl/KxMmtG to delimit the end of the options. npm will pass all the arguments	after  the  --	directly  to  your
       script:

	 npm run test -- --grep="pattern"

       The arguments will only be passed to the script specified after npm run and not to any pre or post script.

       The  env  script  is a special built-in command that can be used to list environment variables that will be available to the script at run-
       time. If an "env" command is defined in your package, it will take precedence over the built-in.

       In addition to the shell's pre-existing PATH, npm run adds node_modules/.bin to the PATH provided to  scripts.  Any  binaries  provided	by
       locally-installed  dependencies	can  be used without the node_modules/.bin prefix. For example, if there is a devDependency on tap in your
       package, you should write:

	 "scripts": {"test": "tap test/*.js"}

       instead of

	 "scripts": {"test": "node_modules/.bin/tap test/*.js"}

       to run your tests.

       The actual shell your script is run within is platform dependent. By default, on Unix-like systems it is the /bin/sh command, on Windows it
       is    the    cmd.exe.	 The	actual	  shell    referred    to    by    /bin/sh    also    depends	 on   the   system.    As   of	 `
       https://github.com/npm/npm/releases/tag/v5.1.0 you can customize the shell with the script-shell configuration.

       Scripts are run from the root of the module, regardless of what your current working directory is when you call npm run. If you	want  your
       script  to use different behavior based on what subdirectory you're in, you can use the INIT_CWD environment variable, which holds the full
       path you were in when you ran npm run.

       npm run sets the NODE environment variable to the node executable with which npm is executed. Also, if the  --scripts-prepend-node-path	is
       passed,	the  directory	within	which node resides is added to the PATH. If --scripts-prepend-node-path=auto is passed (which has been the
       default in npm v3), this is only performed when that node executable is not found in the PATH.

       If you try to run a script without having a node_modules directory and it fails, you will be given a warning to run npm	install,  just	in
       case you've forgotten.

       You can use the --silent flag to prevent showing npm ERR! output on error.

       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.
