gulp-js-inheritance

Rebuild a js file with other files that have extended or included those file

Based on gulp-sass-inheritance

Uses js-graph-imports for the heavy lifting.

Suport _partials.js and nested imports. Import in js:

//import("bar.js")

Install

npm install gulp-js-inheritance --save

Usage

You can use gulp-js-inheritance with gulp-changed to only process the files that have changed but also recompile files that import the one that changed.

'use strict';
var gulp = require('gulp');
var jsInheritance = require('gulp-js-inheritance');
var cached = require('gulp-cached');
var gulpif = require('gulp-if');
var gulpif = require('gulp-uglify');
var filter = require('gulp-filter');

gulp.task('js', function() {
    return gulp.src('src/scripts/**/*.js')

      //filter out unchanged scss files, only works when watching
      .pipe(gulpif(global.isWatching, cached('js')))

      //find files that depend on the files that have changed
      .pipe(jsInheritance({dir: 'src/scripts/'}))

      //filter out internal imports (folders and files starting with "_" )
      .pipe(filter(function (file) {
        return !/\/_/.test(file.path) || !/^_/.test(file.relative);
      }))

      //process js files
      .pipe(uglify())

      //save all the files
      .pipe(gulp.dest('dist'));
});
gulp.task('setWatch', function() {
    global.isWatching = true;
});
gulp.task('watch', ['setWatch', 'js'], function() {
    //your watch functions...
});
