Handling Multiple Entry Points with Browserify in Gulp

Handling Multiple Entry Points with Browserify in Gulp

21 May 2024 Stephan Petzl Leave a comment Tech-Help

When working with Browserify and Gulp, you may encounter challenges, especially if your project requires multiple entry points. This is particularly common when compiling tests, which often lack a single entry point. This guide provides a clear solution to manage multiple entry points effectively.

Understanding the Problem

Typically, Browserify is straightforward when dealing with a single entry point. However, complications arise when you need to compile tests with multiple entry points, leading to errors stating that Browserify can’t find the entry point. Here’s an effective way to handle this scenario.

Solution Overview

The primary approach involves using an external library to gather filenames into an array and passing that array as the entry points for Browserify. Below is a task that demonstrates this solution.

Step-by-Step Implementation

Follow these steps to set up your Gulp task to handle multiple entry points:

1. Set Up Your Dependencies

Ensure you have the required packages installed:

npm install gulp browserify vinyl-source-stream glob gulp-plumber

2. Define Your Gulp Task

Create a task in your gulpfile.js to handle multiple entry points:

'use strict';

var gulp = require('gulp');
var plumber = require('gulp-plumber');
var glob = require('glob');
var browserify = require('browserify');
var source = require('vinyl-source-stream');

gulp.task('tests', function(){
  var testFiles = glob.sync('./spec/**/*.js');
  return browserify({
      entries: testFiles,
      extensions: ['.jsx']
    .bundle({debug: true})

3. Running the Task

Run your Gulp task using the command:

gulp tests

Alternative Method

If you prefer a method more aligned with the Gulp paradigm, using gulp.src and vinyl-transform can be an effective alternative:

var gulp = require('gulp');
var browserify = require('browserify');
var transform = require('vinyl-transform');
var concat = require('gulp-concat');

gulp.task('browserify', function () {
  var browserified = transform(function(filename) {
    var b = browserify(filename, {
      debug: true,
      extensions: ['.coffee']
    return b.bundle();

  return gulp.src(['./app/js/**/*Spec.coffee'])

gulp.task('default', ['browserify']);


Handling multiple entry points in Browserify can be efficiently managed with the right setup in Gulp. By following the steps outlined above, you can compile your tests into a single file without errors.
