simple and quick module definition library in web application.
Only considering that all resources has loaded in html file.
<!doctype html>
<!-- import define -->
<script type="text/javascript" src="./lib/define.js"></script>
<!-- load your libraries -->
<script type="text/javascript" src="./scripts/app.js"></script>
<script type="text/javascript" src="./scripts/c.js"></script>
<script type="text/javascript" src="./scripts/a.js"></script>
<script type="text/javascript" src="./scripts/b.js"></script>a.js is depending on b.js, and it's loading before b.js. And use return to define a module.
define('module.a', [], function (exports) {
return {
value: 'a'
};
});b.js is a standalone module. And use exports.property to extend module.
define('module.b', ['module.a'], function (exports, a) {
exports.value = a.value + 'b';
});c.js is a asynchronous module. And use callback to init.
define('module.c', ['module.a', 'module.b'], function (exports, a, b, callback) {
setTimeout(function () {
callback({ value: a.value + b.value + 'c' });
}, 1000);
});but in app.js, it's depending on the container module (not explicitly define in file).
use(['module'], function (module) {
console.log(module.a.value);
console.log(module.b.value);
console.log(module.c.value);
});
// output
// a
// ab
// aabcCopyright (c) 2013 Wang Qiu (winsonwq@gmail.com)
