webpack4 splitChunks: 'all' support

[wangzuo]

For the following config in webpack4,

  optimization: {
    splitChunks: {
      chunks: 'all'
    },
    runtimeChunk: true
  }

In the webpack output stats, there is a list of files needed for each entrypoint like

Entrypoint about = runtime~about-b126ba8d5183247aa513.js vendors~about~home-bf6fa999743882049ea0.js about-f2320ebef52984b8b8a2.js
Entrypoint home = runtime~home-6b634e8923dcf64c8687.js vendors~about~home-bf6fa999743882049ea0.js static/css/home.3a775e54.chunk.css home-3a775e546f2420ba6807.js static/css/home.3a775e54.chunk.css.map

I am wondering is there any way to support this format in manifest plugin output?

[mastilver]

Can you give us the actual and expected manifest?

I would think we support that, if not then that's an issue

[wangzuo]

I would expect a manifest file with entrypoint support like

"about.js": ["/packs/runtime~about-b126ba8d5183247aa513.js", "/packs/vendors~about~home-bf6fa999743882049ea0.js", "/packs/about-f2320ebef52984b8b8a2.js"],

instead of

{
  "runtime~about.js": "/packs/runtime~about-b126ba8d5183247aa513.js",
  "vendors~about~home.js": "/packs/vendors~about~home-bf6fa999743882049ea0.js",
  "about.js": "/packs/about-f2320ebef52984b8b8a2.js"
}

Oh, I see. I'm afraid it's the correct behaviour

Did you try using https://github.com/danethurber/webpack-manifest-plugin#hooks-options ?

[wangzuo]

Thanks, guess thats what i want

[mastilver]

Let me know if you think a new options should be added to make that job easier

[wangzuo]

I dont think its possible with current implementation, the entrypoints available in new compilation.chunkGroups. The following is my implementation to add an extra entrypoints field in the manifest file, wondering someone find a better way for this feature.

    manifest.entrypoints = compilation.chunkGroups.reduce((result, group) => {
      const files = new Set();
      group.chunks.forEach(chunk => {
        chunk.files.forEach(file => {
          files.add(`${chunk.name}${extname(file)}`);
        });
      });
      result[group.name] = Array.from(files);
      return result;
    }, {});

I will try to have a look when I have time, a failing test would help a lot

Has this issue been resolved? @wangzuo could you share an example how you fixed it?

[wangzuo]

@bf webpack-assets-manifest works

Thank you. In the meantime I have adapted WebpackSplittingManifestPlugin to work with webpack 4 and our specific AggressiveSplittingPlugin use case.

[FranklinWhale]

Is there any update on this issue? I think this plugin should support entrypoints like webpack-assets-manifest.

please fix
