webpack plugin for gulp

var gulp = require('gulp');
var webpack = require('gulp-webpack');
gulp.task('default', function() {
  return gulp.src('src/entry.js')
    .pipe(webpack())
    .pipe(gulp.dest('dist/'));
});

The above will compile src/entry.js into assets with webpack into dist/ with the output filename of [hash].js (webpack generated hash of the build).

You can pass webpack options in with the first argument, including watch which will greatly increase compilation times:

return gulp.src('src/entry.js')
  .pipe(webpack({
    watch: true,
    module: {
      loaders: [
        { test: /\.css$/, loader: 'style!css' },
      ],
    },
  }))
  .pipe(gulp.dest('dist/'));

Or just pass in your webpack.config.js:

return gulp.src('src/entry.js')
  .pipe(webpack( require('./webpack.config.js') ))
  .pipe(gulp.dest('dist/'));

If you would like to use a different version of webpack than the one this plugin uses, pass in an optional 2nd argument:

var gulp = require('gulp');
var webpack = require('webpack');
var gulpWebpack = require('gulp-webpack');
gulp.task('default', function() {
  return gulp.src('src/entry.js')
    .pipe(gulpWebpack({}, webpack))
    .pipe(gulp.dest('dist/'));
});

Pass in 3rd argument if you want to access the stats outputted from webpack when the compilation is done:

var gulp = require('gulp');
var webpack = require('gulp-webpack');
gulp.task('default', function() {
  return gulp.src('src/entry.js')
    .pipe(webpack({
      /* config */
    }, null, function(err, stats) {
      /* Use stats to do more things if needed */
    }))
    .pipe(gulp.dest('dist/'));
});

A common request is how to handle multiple entry points. You can continue to pass in an entry option in your typical webpack config like so:

var gulp = require('gulp');
var webpack = require('gulp-webpack');
gulp.task('default', function() {
  return gulp.src('src/entry.js')
    .pipe(webpack({
      entry: {
        app: 'src/app.js',
        test: 'test/test.js',
      },
      output: {
        filename: '[name].js',
      },
    }))
    .pipe(gulp.dest('dist/'));
});

Or pipe files through a stream that names the chunks. A convenient library for this is vinyl-named:

var gulp = require('gulp');
var webpack = require('gulp-webpack');
var named = require('vinyl-named');
gulp.task('default', function() {
  return gulp.src(['src/app.js', 'test/test.js'])
    .pipe(named())
    .pipe(webpack())
    .pipe(gulp.dest('dist/'));
});

The above named() stream will add a .named property to the vinyl files passing through. The webpack() stream will read those as entry points and even group entry points with common names together.
