multibundle-mapper

Writable stream that accepts r.js config objects and writes mapping/bundling meta data into provided file of specified format (json, js, html).

Example

var multibundle = require('multibundle')
  , Mapper      = require('multibundle-mapper')
  , options     = require('./options/bundles.js')
  , config      = require('./options/config.js')
  ;
 
// optimize
var bundler = multibundle(config, options);
var bundleMapper = Mapper.json('config/local.json', {prefix: config.prefix});
 
bundler.pipe(bundleMapper);
