browserify-assets

finds and transforms the assets (currently just stylesheets) in your browserify-based app

THIS PROJECT IS NO LONGER MAINTAINED

:warning: If you are interested in taking over maintainership, please file an issue

example

assuming you have a project consisiting of one or more commonjs modules (app) and you want to build js and css bundles from those modules to serve up (public/bundle.js, public/bundle.css):

project/
├── app
│   ├── index.js
│   ├── package.json
│   └── style
│       └── test.less
└── public

app/package.json

{
  "name": "app",
  "version": "0.0.1",
  "main": "index.js",
  "style" : "style/*.less",
  "transforms" : ["less-css-stream"],
  "dependencies": {
    "less-css-stream": "^0.1.2"
  }
}

For each package, specify a "style" property with a glob path to find stylesheets.

Specify a "transforms" property with an array of transforms to be applied to assets (eg. to compile less to css). Transforms can be parcelify transforms or any function having the same signature a browserify transform. Writing your own transforms is easy, see the relevant browserify handbook section for more information.

building via CLI

$ browserify-assets -v --bundlename ./public/bundle ./app
> finished writing public/bundle.css
> finished writing public/bundle.js

CLI usage

browserify-assets --bundlename public/bundle ./app
# outputs public/bundle.js, public/bundle.css
# equivalent
browserify-assets --outfile public/bundle.js --cssfile public/bundle.css ./app
# or
browserify-assets --cssfile public/bundle.css ./app > public/bundle.js

supported opts

The following options are available in addition to the standard browserify opts:

• -o or --outfile: the filepath which js will be output to (otherwise js is output to stdout)
• --cssfile: the filepath which css will be output to
• --bundlename: if you specify bundlename (instead of outfile and cssfile), then js will be output to [bundlename].js and css will be output to [bundlename].css.
• -v or --verbose: log when finished writing each output file
• --cachefile: where the incremental build cache will be stored. Defaults to browserify-cache.json in current working directory.

API usage

var b = browserifyAssets(opts);

// or, provide your own browserify instance
// note: you must include the args:
// { cache: {}, packageCache: {}, fullPaths: true }
// which can be copied from browserifyAssets.args
var b = browserify(xtend(browserifyAssets.args, {
  // your opts
}));
browserifyAssets(b);

supported opts

The following constructor opts are available in addition to the standard browserify opts:

• cacheFile: where the incremental build cache will be stored. If not specified, only in-memory caching will be used.

example

var fs = require('fs');
var browserifyAssets = require('browserify-assets');

// specifying a cacheFile will allow for super fast rebuilds
// even from a cold start (eg. across multiple runs of the executable)
var opts = {cacheFile: __dirname+'/tmp/cache.json'};

var b = browserifyAssets(opts);

b.add(__dirname + '/app');

function build(done) {
  b.on('allBundlesComplete', done);
  b.on('assetStream', function(assetStream) {
    assetStream.on('error', done);
    // output css here
    assetStream.pipe(fs.createWriteStream(__dirname+'/public/bundle.css'));
  });
  var bundleStream = b.bundle();
  bundleStream.on('error', done);
  // output js here
  bundleStream.pipe(fs.createWriteStream(__dirname+'/public/bundle.js'));
}

build(function(err) {
  if (!err) {
    // you now have a js bundle and a css bundle
  } else {
    console.error(err);
  }
});
