Support rspack

[singh-jay]

If the feature solves a problem you have, specify it here.

I'm trying to migrate our webpack project to rspack, everything is working except the svg-sprites, as this project is in active development, I hope you will consider support for rspack as well.

Describe the proposed feature.

Getting error -
/node_modules/svg-chunk-webpack-plugin/lib/loader.js:20
this._module.factoryMeta = this._module.factoryMeta || {};
^

TypeError: Cannot read properties of undefined (reading 'factoryMeta')

Describe alternatives you've considered

Hello @singh-jay, thanks for your feedback.

I'm not opposed to compatibility with rspack, but it seems complicated to me because there are differences in the API.

On investigating, I can already see 2 points that pose a problem:

1. From the loader, this._module is not available with rspack and this is used to mark SVGs for the plugin (see Nested dependencies are different between development mode and production mode webpack/webpack#12202 (comment))
2. From the plugin, entry.chunks doesn't return anything. The getSvgsDependenciesByEntrypoint function allows you to search for SVG dependencies associated with an entrypoint.

@alexander-akait (Hi) What do you think?

We can add check if (this._module) {}, it prevent from crash, but I am not sure it will work correctly, need to test, also maybe we need to more API... will be great to dicussion about it with rspack team

Sorry for the delay, this line is important because it marks the svgs for the plugin. If it's not marked, the plugin will ignore the svg and won't work properly.

@alexander-akait Do you have contact with the rspack team? Or do you know how we could solve this problem? Thanks
