The request of a dependency is an expression [webpack]

[moshfeu]

Disclaimer: Maybe it's non issue.

I'm using this library (part of youtube-mp3-downloader) with webpack@4.21.0 and I get the warning below.

As much as I understand, webpack doesn't "like" dynamically require. You can get more info here.

Version information

• fluent-ffmpeg version: 2.1.2
• ffmpeg version: irelevant
• OS: macos

Expected results

This library will not cause webpack to warn

Observed results

Webpack does warn about:

/node_modules/fluent-ffmpeg/lib/options/misc.js 27:21-40
Critical dependency: the request of a dependency isan expression

Checklist

• I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place) - Irelevant
• I have included full stderr/stdout output from ffmpeg - Irelevant

Thanks!

Yes, this is known and is a side effect of the way our coverage testing is implemented.

If anyone comes up with a better solution, I'd be glad to merge it 😉

hey @moshfeu i found a way to fix it. check the MR #1077 while waiting for it to be merged and (maybe 😃 ) release

temporary solution with webpack externals:

 const IGNORES = ['fluent-ffmpeg']
 return function (context, request, callback) {
        if (IGNORES.includes(request)) {
            return callback(null, `require('${request}')`)
        }
       return callback()
 }
