A experimental module loader with the same APIs of SeaJS(https://seajs.org).
Define a module.
define('foo.js', [ 'bar.js' ], function (require, exports, module) {
var bar = require('bar.js');
require.async('baz.js', function (baz) {
// ...
});
// ...
});
Use modules by id. 'callback' is executed when all modules ready.
seajs.use('foo', function (foo) {
// ...
});
seajs.use([ 'bar', 'baz' ], function (bar, baz) {
// ...
});
Deep-merge configuration in option object with existing ones.
seajs.config({
alias: {
'foo': 'https://foo.com',
},
base: 'https://bar.com/',
charset: 'utf-8'
});
Add an AOP handler before an internal method.
seajs.before('load', function (uris) {
return [ combo(uris) ];
});
Add an AOP handler after an internal method.
seajs.after('resolve', function (uri) {
return map(uri);
});
Module ID is a unique full URI assigned with a module. Module ID could write in partial or alias form but will be resolved to full URI finally.
Full URI is used as it is.
seajs.use('https://foo.com/bar.js');
Partial URI could be a relative pathname or a absolute pathname. In HTML page, relative pathname is resolved based on page URI. In a module, relative pathname is resolved based on module ID. And absolute pathname is always resolved based on seajs base configuration.
# in https://foo.com/index.html
seajs.use('./bar.js') // equals => seajs.use('https://foo.com/bar.js')
# in https://foo.com/bar.js
require('./baz.js') // equals => require('https://foo.com/baz.js')
# base is configured to 'https://foo.com/bar/'
require('baz.js') // equals => require('https://foo.com/bar/baz.js')
If module ID is writen in absolute pathname, the first part could be an alias.
# define alias: 'bar': 'https://foo.com/bar'
require('bar/baz.js') // equals => require('https://foo/bar/baz.js')
Prepend # to ID can prevent alias parsing.
# define alias: 'bar': 'https://foo.com/bar'
# base is configured to 'https://foo.com/bar/'
require('#bar/baz.js') // equals => require('https://foo/bar/bar/baz.js')
If a URI does not have an extname, or not contain ?, .js is appended to URI by default.
# in https://foo.com/bar.js
require('./baz') // equals => require('https://foo.com/baz.js')
Append '#' to ID can prevent default extname appending.
# in https://foo.com/bar.js
require('./baz#') // equals => require('https://foo.com/baz')
