javascript - ES6 async modules using multiple baseurls -

the es6 module system seems proper fit unifying commonjs / amd syntaxes. requirejs/amd-user i'd convert es6 modules (using babel.js now).

there seems 1 problem though; reading through docs , tutorials, there doesn't seem possible load module packages dependendent on more 1 baseurl. using requirejs solvable using context field:

// async dependencies loaded http://path/to/domain var contextedrequire1 = require.config({   baseurl: 'http://path/to/domain/js',   context: 'maincontext' });      // async dependencies located on http://path/to/otherdomain var contextrequire2 = require.config({   baseurl: 'http://path/to/otherdomain/js',   context: 'plugincontext' });  contextedrequire1(['main.js'], function(main){   // loaded using http://path/to/domain/js/main.js   contextedrequire2(['plugin-lazyloading-deps.js'], function(plugin){     plugin.init();   }); }); 

in main.js

define(['main-deps'], function(maindeps){   // loaded using http://path/to/domain/js/main-deps.js }) 

in plugin-lazyloading-deps.js

define(['require'], function(require){   // loaded using http://path/to/otherdomain/js/plugin-lazyloading-deps.js   if(modernizr.touch) {     require(['hammer'], function(){       // loaded using http://path/to/otherdomain/js/hammer.js       hammer.init();     })   } }) 

in es6 async module imports isn't possible, since system singleton

system.baseurl = "http://path/to/domain/js"; system.import("main").then(function(main){   // loaded using http://path/to/domain/js/main.js    // potentially break when main.js tries load hammer.js http://path/to/domain/js   system.baseurl = "http://path/to/otherdomain/js";   system.import("plugin-lazyloading-deps").then(function(){ /** code **/ }); }); 

my question is: there in docs i've missed (possible subclass system able config several baseurls), or in works future module extensions?

at least current version of systemjs, can provide wildcard paths. https://github.com/systemjs/systemjs/wiki/configuration-options#paths-unstable

i haven't used myself, case, seems you'd do

system.baseurl = 'http://path/to/domain/js'; system.paths['plugin-*'] = 'http://path/to/otherdomain/js/plugin-*';
