Gulp-npm-run NPM

gulp-npm-run

Creates gulp tasks for your npm scripts. Notifies if a task fails, using node-notifier via childish-process. Notifications can be customized.

Use

As simple as it gets:

var gulp = require('gulp-npm-run')(require('gulp'));

Configure

It can take configuration options, here are a few of them:

var gulp = require('gulp-npm-run')(require('gulp'), {
  exclude: ['test'], // the test script is excluded
  include: {'necessary': 'a must-have task, because...'} // just a helpful description
  require: ['necessary'], // maybe because other tasks depend it
  requireStrict: false,
  npmRun: false // rather than `npm run script` gulp runs the script's value / command(s)
});

By require we insist there must be corresponding scripts in package.json - it's a declaration of assumptions or dependencies to insist on being satisfied. Use requireStrict: true to make sure require is actually satisfied - gulp will not run any tasks until all the scripts are found, with this option. There will be a warning in either case. Require is a separate concern with regards to exclude, a script can be both required and excluded -- i.e. if it's expected in package.json without corresponding task created, for whatever reason.

The test script / task is good to exclude in favor of gulp-npm-test, which does the same, only better. Or, perhaps because you'd like to implement your very own test task. In any case, excluding scripts isn't strictly required to gulp-implement them, as one can simply call gulp.task to replace any pre-existing task code. Anyway, there may be npm scripts for which you do not want to have gulp tasks. Exclude enables that.

Include / Help

The counterpart of exclude is include, which could be an Array whitelist. Its more useful form is an Object, the keys corresponding to npm scripts, the values as help for gulp-help. In accordance with its gulp.task api this help can be a message String, or false in which case the script's gulp task doesn't show with gulp help. All tasks created by gulp-npm-run will have help messages by default - these basically show what the script (i.e. command) being npm run is, exactly. Use the new task api to describe tasks subsequently added, if more complete documentation is desired.

gulp help

However, please note that in order to enable help, you'd either have to either:

use beverage for this and other reasons,
or setup gulp-help on your own:

var gulp = require('gulp-npm-run')(require('gulp-help')(require('gulp')));

Help is entirely optional, gulp-npm-run does not modify gulp's api for you.

Further

See datomiki for a practical, somewhat more advanced usage example.
