Browserify - multiple entry points

Question

I am using Browserify within gulp. I am trying to compile down my tests to a single file as well. But unlike my main app, which I have working just fine, I am having trouble getting the tests to compile. The major difference is the tests have multiple entry points, there isn't one single entry point like that app. But I am getting errors fro Browserify that it can't find the entry point.

browserify   = require 'browserify'
gulp         = require 'gulp'
source       = require 'vinyl-source-stream'

gulp.task 'tests', ->
    browserify
        entries: ['./app/js/**/*Spec.coffee']
        extensions: ['.coffee']
    .bundle 
        debug: true
    .pipe source('specs.js') 
    .pipe gulp.dest('./specs/')

Answer 1

Below is a task I was able to build that seems to solve the problem. Basically I use an outside library to gather the files names as an array. And then pass that array as the entry points

'use strict;'

var config = require('../config');
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})
    .pipe(source('app.js'))
    .pipe(plumber())
    .pipe(gulp.dest(config.dest.development));
});

Here's an alternate recipe that fits more with the gulp paradigm using gulp.src()

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

gulp.task('browserify', function () {

  // use `vinyl-transform` to wrap around the regular ReadableStream returned by b.bundle();
  // so that we can use it down a vinyl pipeline as a vinyl file object.
  // `vinyl-transform` takes care of creating both streaming and buffered vinyl file objects.
  var browserified = transform(function(filename) {
    var b = browserify(filename, {
      debug: true,
      extensions: ['.coffee']
    });
    // you can now further configure/manipulate your bundle
    // you can perform transforms, for e.g.: 'coffeeify'
    // b.transform('coffeeify');
    // or even use browserify plugins, for e.g. 'minifyiy'
    // b.plugins('minifyify');
    // consult browserify documentation at: https://github.com/substack/node-browserify#methods for more available APIs
    return b.bundle();
  });

  return gulp.src(['./app/js/**/*Spec.coffee'])
    .pipe(browserified)/
    .pipe(concat('spec.js'))
    .pipe(gulp.dest('./specs'));
});

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