I tried to load the Google APIs Client Library for JavaScript with requirejs and the async plugin:
require.config({
TL;DR; change the !callback to !onload that should fix the timeout.
define('gapi', ['async!https://apis.google.com/js/client.js!onload'],
function(){
console.log('gapi loaded');
return gapi.client;
}
);
The value after the ! is used as the argument name for the async callback, in this case the URI loaded will be something like https://apis.google.com/js/client.js?onload=__async_req_3__ where __async_req_3__ is a global variable (callback function) triggered as soon as the Google API is loaded (notifies the plugin that all dependencies are met).
