gulp

Usage With Gulp

Using webpack with gulp is as easy as using the node.js API.

Using webpack-stream

var gulp = require('gulp');
var webpack = require('webpack-stream');
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 (a webpack-generated hash of the build).

Or just pass in your webpack.config.js:

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

See webpack-stream for more options and details.

Without webpack-stream

var gulp = require("gulp");
var gutil = require("gulp-util");
var webpack = require("webpack");
var WebpackDevServer = require("webpack-dev-server");

Normal compilation

gulp.task("webpack", function(callback) {
    // run webpack
    webpack({
        // configuration
    }, function(err, stats) {
        if(err) throw new gutil.PluginError("webpack", err);
        gutil.log("[webpack]", stats.toString({
            // output options
        }));
        callback();
    });
});

webpack-dev-server

Don’t be too lazy to integrate the webpack-dev-server into your development process. It’s an important tool for productivity.

gulp.task("webpack-dev-server", function(callback) {
    // Start a webpack-dev-server
    var compiler = webpack({
        // configuration
    });

    new WebpackDevServer(compiler, {
        // server and middleware options
    }).listen(8080, "localhost", function(err) {
        if(err) throw new gutil.PluginError("webpack-dev-server", err);
        // Server listening
        gutil.log("[webpack-dev-server]", "http://localhost:8080/webpack-dev-server/index.html");

        // keep the server alive or continue?
        // callback();
    });
});

Example

Take a look at an example gulpfile. It covers three modes:

• webpack-dev-server
• build - watch cycle
• production build
