捆绑，RequireJS和CDN-他们互相取消了吗？-Bundling,RequireJS,andCDNs-Dotheycanceleachotherout?

Whereas RequireJS is used so that files can be loaded dynamically and asynchronously, as they're needed.

而使用RequireJS,以便可以根据需要动态和异步地加载文件。

Many developers use RequireJS to have a clean way to separate concerns without the need for loading modules dynamically. I have a few applications and libraries developed with RequireJS. One of them is a library that does not use the dynamic loading capabilities at all and would not benefit from using them. In almost all use-case scenarios for this library, it should be loaded as a single bundle, and not as a collection of modules, one-by-one.

许多开发人员使用RequireJS来分离关注点,而无需动态加载模块。我有一些使用RequireJS开发的应用程序和库。其中之一是一个根本不使用动态加载功能的库,并且不会从使用它们中受益。在这个库的几乎所有用例场景中,它应该作为单个包加载,而不是作为模块的集合一个接一个地加载。

This brings me to another thing: the decision is not between bundling or RequireJS. You can use r.js (RequireJS' optimizer) to bundle your RequireJS modules into a single file for production. This could include 3rd party modules if you want. Or you could leave them out to be served from a CDN. An application can be optimized to a single bundle, or a series of bundles. As any other optimization question, what should be done depends on the architecture of the specific application being considered.

这让我想到了另一件事:决定不是在捆绑或RequireJS之间。您可以使用r.js(RequireJS'优化器)将RequireJS模块捆绑到单个文件中进行生产。如果您愿意,这可能包括第三方模块。或者你可以把它们留在CDN服务。应用程序可以针对单个捆绑包或一系列捆绑包进行优化。与任何其他优化问题一样,应该做什么取决于所考虑的特定应用程序的体系结构。

The rest of your question is wholly opinion-based. I've seen detailed arguments supported by statistics that you should use a CDN, that you should not use a CDN, and everything in between. It is an optimization question, which, again, depends on the specifics of the application being considered.

你的其余部分完全基于意见。我已经看到统计数据支持的详细论据,你应该使用CDN,你不应该使用CDN,以及介于两者之间的所有内容。这是一个优化问题,它同样取决于所考虑的应用程序的细节。

So if we bundle all our JS files into 1, is RequireJS even needed?

因此,如果我们将所有JS文件捆绑为1,甚至需要RequireJS吗?

Not all of it. You might be interested in almond.

不是全部。您可能对杏仁感兴趣。

A replacement AMD loader for RequireJS. It provides a minimal AMD API footprint that includes loader plugin support. Only useful for built/bundled AMD modules, does not do dynamic loading.

RequireJS的替代AMD加载程序。它提供了最小的AMD API占用空间,包括加载程序插件支持。仅对构建/捆绑的AMD模块有用,不进行动态加载。
