miniCssExtractPlugin breaks karma-webpack. Since i dont require styles one way or the other for my unit tests I just remove it from the webpack entry of karma.config as a workarround.

MiniCssExtractPlugin = require 'mini-css-extract-plugin'
webpackConfig = require './webpack.config'

removeMiniCssExtract = (conf) ->
    for rule in conf.module.rules
        if rule.use
            rule.use = rule.use.filter( (u) -> u != MiniCssExtractPlugin.loader)
    return conf

# ...
 webpack: removeMiniCssExtract(webpackConfig)

@bdirito tried it but it didn't work... Karma-webpack is still receiving multiple entry points. What syntax is that code by the way?

Besides the mini CSS extract plugin, enabling source maps also results in multiple entry points being passed (.js and .js.map), but maybe I'm doing something wrong here...

alabbas-ali · 2018-10-11T09:58:52Z

I can't see the need to have such work workarround. if merging this branch will solve the problem. I test it also with MiniCssExtractPlugin and it is working fine.

bdirito · 2018-10-11T16:47:45Z

@mario-d-s MiniCssExtractPlugin is only one example of a webpack plugin that produces this issue. Various other plugins can and will also trigger this issue so it will not work in cases where you are using those. Depending on what those plugins do it may or may not be possible to remove them in the same manner, I can only do this because css is irrelevant for my unit testing. The syntax is coffeescript.

@alabbas-ali I would prefer to have a fix merged in to webpack-karma but in the absence of that happening (why is review taking so long for an 'urgent regression'?) I wanted something that didnt require building before use. Ideally this issue would be fixed and any such workarounds can be removed.

(why is review taking so long for an 'urgent regression'?)

I'd also like to know. Can this please be merged and released?

Any updates on this? Would be really great to have this merged so that I can go forward with upgrading to Webpack 4.

@michael-ciniawsky any updates?

thijstriemstra · 2018-11-07T13:05:32Z

Why is this not merged...

43081j · 2018-11-08T11:05:31Z

I'm seeing a lot of issues in both 3.x and 4.x around sourcemaps and such too.

3.x has a fix in place for multiple outputs but it introduces more issues than it resolves. It means things like sourcemaps are lost/broken as their outputs are thrown away.

This may resolve the issue. If it does, it needs to be added to 3.x too if thats still being maintained.

neemski · 2018-11-15T23:26:11Z

@rynclark @michael-ciniawsky any updates on this? As many have pointed out, we are blocked from upgrading to Webpack 4 until this is merged/released

edmorley · 2018-11-20T10:42:13Z

Please can we review/merge this?

At this point just switching wholesale to Jest is seeming very appealing.
The Karma ecosystem seems to be in decline.

alexander-akait · 2018-11-20T10:53:08Z

We need contributor for this loader, there is no one here right now, so if you can and have time for this ping me in gitter (https://gitter.im/webpack/webpack)

matthieu-foucault · 2018-11-20T16:32:31Z

I just got collaborator access. Bear with me as I am trying to get this merged. Currently, I cannot do that as the TravisCI build is pending (and will stay that way). It seems that this check has been ignored since #344 (at least) and that admin rights have been used to merge PRs.

If an admin sees this, can you please disable the required check?

alexander-akait · 2018-11-20T17:21:14Z

@matthieu-foucault temporary disable, need fix

matthieu-foucault · 2018-11-20T17:41:21Z

Well, I still can't merge this. Looks like only an admin can merge to master.

ryanclark · 2018-11-20T17:43:09Z

Yeah, that's why I didn't merge - we need @michael-ciniawsky as far as I'm aware

matthieu-foucault · 2018-11-20T17:46:48Z

@evilebottnawi seems to be able to change these things. Can you add @rynclark (my help isn't needed if Ryan is available) to the list of contributors allowed to push to master?

ryanclark · 2018-11-20T17:47:59Z

Thanks @matthieu-foucault. I'm also not able to publish to npm, though. // @evilebottnawi
