How to automatic run gulp tasks via npm

0 votes

I usually run gulp via npm, e.g. in my package.json

"scripts": {
    "test": "gulp test",
    "minify": "gulp minify"
}

Then I can run command such as

npm run minify

Which is okay, but every time I've new tasks in my gulpfile, I need to add them to the package.json under the scripts section, is there any better way to do so?

I only install npm globally to my path so all other modules will not pollute my path, so I need to run them via npm scripts

Hello @kartik,

Here is the code:

  var file = fs.readFileSync(config.path || 'package.json', 'utf-8');
  var pkg = JSON.parse(file);
  var tasks = gulp.tasks;

  pkg.scripts = pkg.scripts || {};

  Object.keys(tasks).forEach(function (t) {
    pkg.scripts[t] = 'gulp '+tasks[t].name;
  });

So use: npm install --save-dev gulp-npm-script-sync

Stick this in your gulpfile:

var gulp = require('gulp');
var sync = require('gulp-npm-script-sync');

// your gulpfile contents

sync(gulp);

Every time you update your gulpfile with a new task it will update your package.json.

You can even throw it inside a gulp task:

gulp.task('sync', function () {
  sync(gulp);
}
