requirejs-promised

RequireJS plugin to get decorated require that returns a promise

Use

Instead of usual

require(["require", ...], function (require, ...) {
  // ...
  require(["module/id", "module/id2"],
    function (module1, module2) {...}/*, errback*/
  );
  // ...
});

you can use

require(["promised!require", ...], function (require, ...) {
  // ...
  require(["module/id", "module/id2"])
    .then(function (moduleArray) {...})
    // .catch(errback)
    ;
  // ...
});

or, in ES2015,

require(["promised!require", ...], function (require, ...) {
  // ...
  require(["module/id", "module/id2"])
    .then(([module1, module2]) => {...})
    // .catch(errback)
    ;
  // ...
});

With all the niceties of promises, like later attachment of handler, etc.

The global Promise must be present. It's your responsibility to polyfill it if needed (require('es6-promise').polyfill(); is an easy way).

In other words, promised!require works just like plain require for sync case require("module/id"), but in case of async call, it returns a Promise which resolves to array of modules if succeeded, or it rejects with an error if failed.
