Rebuild css modules with defined order

[Diokuz]

Hi there)

I wrote a-webpack-plugin which makes it possible to generate super short css classNames, like .a .b... .zz ...
My plugin works with ExtractTextPlugin, and it doesn't with mini-css-extract-plugin (

The problem is that when I rebuild css modules in a proper order, mini-css-extract-plugin
just drops all css files → no css output at all.

https://github.com/Diokuz/a-webpack-plugin/blob/master/index.js#L158

Any suggestions how to fix that?

My plugin's algorythm is very simple:

1. Wait till all css modules are loaded by webpack
2. Find them and sort
3. Rebuild all css modules in a defined order, so build is deterministic (chunkhash and content is constant for particular git commit).

As I understood from your source, you use childCompiler in loader, which is reused in plugin part. But I still dont get it, why compilation.rebuildModule not working...

Thanks in advance)

mini-css-extract-plugin no longer uses rebuildMoulde internal, but this shouldn't a problem.

Technically your solution should also work with the mini-css-extract-plugin. I don't know why it doesn't work.

Does a very simple plugin works that just calls rebuildModule work? If not you can build a test case for the mini-css-extract-plugin from this and PR it. That would help.

Thanks! Will do that.

Here we are: No css file with mini-css-extract-plugin demo

It works with ExtractTextPlugin@4 (ETP4 demo), but I cannot use it because of webpack-contrib/extract-text-webpack-plugin#767

[Diokuz]

Actually webpack-contrib/extract-text-webpack-plugin#767 has the same symptoms

Any suggestions so far?)
Is it a bug, or should I use something else?

@Diokuz need fix this bug and send PR

[Diokuz]

Cool! So, it is a confirmed webpack4 bug and it will be fixed in near future?

@evilebottnawi @sokra any news on this issue?)

[alexander-akait]

@Diokuz PR welcome

[Diokuz]

@evilebottnawi unfortunately I have no time to explore webpack code to find out why compilation.rebuildModule doesnt works properly in 4th version :(
No hope to fix that without me?
