Incorrect filename temlate generation behavior

[RAX7]

Bug report

When using .svg files with squooshMinify or sharpMinify (which do not support the svg format), an invalid filename is generated from the filename option.

webpack config:

export default {
  mode: 'production',

  entry: {
    main: path.resolve(__dirname, '../src/scripts/index.js'),
  },

  output: {
    path: path.join(__dirname, '../build'),
    filename: 'js/[name].js',
    clean: true,
  },

  optimization: {
    minimizer: [
      new ImageMinimizerPlugin({
        minimizer: {
          filename: 'minified-xxx-[name]-yyy[ext]',
          implementation: ImageMinimizerPlugin.squooshMinify,
          options: {},
        },
      }),
    ],
  }
};

Actual Behavior

create file:
build/minified-xxx-minified-xxx-minified-xxx-minified-xxx-minified-xxx-minified-xxx-minified-xxx-minified-xxx-svg-file-yyy-c8e115cf-yyy-yyy-yyy-yyy-yyy-yyy-yyy.svg

Expected Behavior

create file:
build/assets/minified-xxx-svg-file-yyy-c8e115cf.svg

How Do We Reproduce?

import svg from './svg-file.svg';

Sounds like you apply the loader multiple times... Can you provide a full configuration, because I can't reproduce, thank you

Try to remove filename: 'minified-xxx-[name]-yyy[ext]', from minified, I don't think you need rename file after minication, assets modules already rename file as you want, this option for exotic cases

[alexander-akait]

If it will not help, can you create reproducible github repo, hard to use code from comments, thank you

[RAX7]

Here is repo with bug

Try to remove filename

No, this does not affect. I have added an option exclude: /\.svg$/i to avoid this behavor, but I still think this a bug.

[alexander-akait]

I see, if you don't do something with files/assets you should exclude them from a plugin, i.e. use /\.(jpe?g|png|gif|tif|webp|avif|jxl)$/i (no svg there), otherwise you will spend build time on nothing (we can't know all possible extensions and different tools support different extensions). Or use exclude as you written above.

But even if we skip them you still will have renamed file, because you set filename (I think you are not expecting this).

[alexander-akait]

@RAX7 So I don't have a strong opinion that we have to do something here, although we can update docs and exclude the svg extension for sharp and squoosh

But I see the DX problem here

[alexander-akait]

Please try https://github.com/webpack-contrib/image-minimizer-webpack-plugin/releases/tag/v3.3.1, anyway I strong recommend to exclude svg for better perf

[RAX7]

@alexander-akait I've tried v3.3.1 and it's works fine for me. Thank you!

So I don't have a strong opinion that we have to do something here

In my opinion, we have only two options: skip the file or throw an error. But in this way, I think there will be a problem with multiple minimizers option. For example: it should be possible to mix the sharp or squoosh minimizer for bitmaps formats and imagemin-svgo for svg. And if first minimizer mark file as unsupported (original.info.original = true) then second one will also skip this file.

Maybe better fix will be move normalizeProcessedResult function outside loop to normalize whole batch result. But I not sure.

[alexander-akait]

@RAX7 Yeah, feel free to send a PR if you have more ideas, currently I jsut skip any actions when file was no changed
