Webpack Ignore Plugin not working?

[YanDevDe]

Hello everyone,

I tried the following method:

new webpack.IgnorePlugin(/^\.\/wordlists\/(?!english)/, /bip39\/src$/)

But for some reason this is not working and I'm still able to get wordlist from other languages. I also tried the old method back in times from #118 which is obviously not working too.

Ignoring other package is working fine at my side, as example for "moment"

new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/)

Was wondering if you could reproduce the issue too?

I'm using Webpack 4.41.5

Could you try with an old version of webpack?

Maybe look on their repo to see which version was latests when I merged that PR. Try that version, and if it works, then try asking webpack devs.

According to the webpack website, perhaps it needs to be this instead?

new webpack.IgnorePlugin({
        resourceRegExp: /^\.\/(?!english)/, 
        contextRegExp: /bip39\/src\/wordlists$/
    })

I ran into this issue today, and decided to log the arguments passed to checkResource (some results excluded):

[Arguments] {
  '0': './_wordlists',
  '1': 'D:\\...\\node_modules\\bip39\\src'
}
[Arguments] {
  '0': './wordlists/chinese_simplified.json',
  '1': 'D:\\...\\node_modules\\bip39\\src'
}
[Arguments] {
  '0': './wordlists/english.json',
  '1': 'D:\\...\\node_modules\\bip39\\src'
}

What I didn't expect was to see the wordlists substring in the first argument, rather than the second. As such, I was able to apply the following change to the config file to exclude non-English lists:

module.exports = {
    plugins: [
        new webpack.IgnorePlugin(/^\.\/wordlists\/(?!english)/)
    ]
}

If you're on Windows, you should use backslash (\) for the context :

new webpack.IgnorePlugin(/^\.\/wordlists\/(?!english)/, /bip39\\src$/)                               ^
