rspack does not properly resolve tsconfig paths.

[RoyalHunt]

Current Behavior

tsconfig.json file:

{ "compilerOptions": { "paths": { "@app/themes/*": ["libs/themes/src/muiThemes/*"] } }, }

it resolves in rspack config as:
resolve: { alias: { '@app/themes/*': 'C:\\Users\\admin\\webApps\\libs\\themes\\src\\muiThemes\\*', }, },

Expected Behavior

tsconfig.json file:
{ "compilerOptions": { "paths": { "@app/themes/*": ["libs/themes/src/muiThemes/*"] } }, }

it should resolve in rspack config as:
{ resolve: { alias: { '@app/themes': 'C:\\Users\\admin\\webApps\\libs\\themes\\src\\muiThemes', }, }, }

I'm struggling with this....

My "workaround" was to update rspack config to use this:

https://rspack.dev/config/resolve#resolvetsconfigconfigfile

So, you point to you app/lib tsconfig file.

I solved it with this workaround in rspack.config.ts:

export default composePlugins(
  withNx(),
  withReact(),
  withModuleFederation(config, { dts: false }),
  (config: any) => {
 
    // Fix to set correct configuration for alias
    const newAlias: Record<string, string> = {};
    for (const key in config.resolve.alias) {
      const newKey = key.replace(/\/\*/g, "");
      const newValue = config.resolve.alias[key].replace(/\\\*/g, "");
      newAlias[newKey] = newValue;
    }
    config.resolve.alias = newAlias;

    return config;
  },
);
