Details

When rslib is set to output in bundleless mode (bundle: false), any registered rspack plugins do not call the normalModuleFactory.hooks.resolve hook on import declarations in the source files.

When rslib is set to output in bundleless mode (bundle: false), a rspack plugin provided to the rslib configuration (tools.rspack.plugins) will not call the normalModuleFactory.hooks.resolve hook for imports in the source files. It will call it on the result of the source.entry glob, but it does not loop through the imports of each source file, calling the hook, as I would expect.

I would expect this especially because it does call the beforeResolve hook on these imports, but then does not call resolve.

This is needed for my use case, as I am using a plugin that, combined with a component library, generates CSS files at build time. It will add the imports to the source files as needed, and then it waits for the the resolve to be called on the path, in order to write out the corresponding CSS file. Because resolve is not being called, the plugin is failing to write out the CSS files.

Reproduce Steps

Described in the reproduction repo readme

Start with the reproduction repository and its README, then inspect how bundleless mode processes the source.entry glob and imports when tools.rspack.plugins are configured. Compare the beforeResolve and resolve hook behavior for import declarations. Done means the normalModuleFactory.hooks.resolve hook runs for those imports so the plugin can generate its CSS files.
