wiredep - respect child dependencies' bower overrides

wiredep_overrides_fix.js

/* 
this hack fixes the following issues:
https://github.com/taptapship/wiredep/issues/149
https://github.com/taptapship/wiredep/issues/183

be aware that:
- this will take overrides from everything in your BOWER_PATH, 
  even packages that you might not depend on
- overrides in your bower.json win

packages this requires:
var glob = require('glob');
var _ = require('underscore');
var wiredep = require('wiredep').stream;
var gulp = require('gulp');
*/

var BOWER_PATH = './bower_components';
var COMPILE_PATH = './compiled';

gulp.task("wiredep", function() {
  return gulp.src(COMPILE_PATH + "/index.html").pipe(wiredep({
    directory: BOWER_PATH,
    overrides: (function() {
        var configs = glob.sync(BOWER_PATH + "/**/bower.json");
        var overrides = {};
        _.each(configs, function(cpath) {
            return _.extend(overrides, require(cpath).overrides || {});
        });
        _.extend(overrides, require(path.join(__dirname, "bower.json")).overrides || {});
        return overrides;
    }())
  })).pipe(gulp.dest(COMPILE_PATH));
