使用requirejs加载一个包含多个类的文件(grunt-concat)

标签: javascript node.js requirejs typescript gruntjs

我对grunt concat和requirejs(和typescript)有点问题。 问题很简单,当我为每个类生成一个文件并且我单独加载每个文件时,我没有问题。 (但浏览器速度较慢) 例如:

  • A.js
  • Message.js
  • ValidatorMessage.js(扩展Message并具有依赖关系)

loader.ts:

require.config({
    paths: {
        'A': '../generated/shared/A.min',
        'Message': '../generated/shared/Message.min',
        'ValidatorMessage': '../generated/shared/ValidatorMessage.min', }//more

那是有效的。我可以在浏览器中要求()每个文件,然后我就可以了。 但如果这样做:

require.config({
        paths: {
            'shared': '../generated/shared.min',

这不起作用。

shared.min.js

我不明白是不是因为在同一个文件或其他内容中有多次调用。你呢?

修改 我忘了说在这个例子中,A类将是可用的浏览器端(和工作),但不是以下。如果我删除A到shared.min.js然后类消息将工作,但不是下一个,所以我只是加载了第一个类加载好了!

EDIT2: 我也忘了说在A不存在的情况下,浏览器中的var消息存在并且正常工作(正如我在 Edit1 中所说的那样)但是也存在var ValidatorMessage!除了它未定义,我的意思是我从浏览器获得自动完成但内部没有任何内容。看起来只有第一个define()将对象设置为全局。

您应该使用r.js optimizer in production,而不是手动将文件连接在一起;否则你将失去模块化代码的好处(每个文件一个类)。让优化器完成确定依赖图的艰苦工作,不要试图重新发明轮子!

这有一个grunt task available
