What is the current behavior?

The local scripts are still remained if the CDN provider is not local. However, they will have never been used.

What is the new behavior?

Remove local scripts if minify is true and the CDN provider is not local.

How to use?

In NexT _config.yml:

minify: true
vendors:
   internal: jsdelivr  # or unpkg, cdnjs

(The current implement is a bit silly. Does some one have a better implement?)

🤔 You yourself have a better implement in #241 (comment) . Like:

hexo.route.list().forEach(path => {
  if (path.startsWith('js/')) hexo.route.remove(path);
});

I am worried that this will break the plugins that add routes into the js directory (I am not sure if such the plugin exists).

[njzjz]

Here is my solution:

Object.keys(hexo.theme._processingFiles).forEach(path => {
  if (path.startsWith('source/js/')) hexo.route.remove(path.slice(7));
});

Tracing how _processingFiles is generated, I found using addProcessor would be a better choice.

// ...

const localScripts = [];

hexo.theme.addProcessor('js/*', (file) => {
  localScripts.push(file.params[0]);
});

hexo.extend.filter.register('after_generate', () => {
  // ...

  if (theme.vendors.internal !== 'local') {
    localScripts.forEach(path => {
      hexo.route.remove(path);
    });
    return;
  }

  // ...
});

works fine.

Nice! It works on my blog.
