Next react compiler incompatibility

[laem]

Hi, Lingui's docs say :

caution

If you're using React Compiler with SWC, the @lingui/swc-plugin must run before the React Compiler plugin. This is necessary because Lingui macros need to be expanded before the React Compiler processes your code.

However, in Next.js, the React Compiler is enabled via a simple boolean flag (reactCompiler: true) in next.config.js, and there's currently no way to control plugin ordering. As a result, Lingui may not work correctly with the React Compiler in SWC-based setups like Next.js.

Where can we find more information about this ? Is this a bug that has been acknowledged by the Next team ? Will it get fixed ? I could not find any information.

I don't know about this. You can create an issue in the Next repository. The current state of Lingui + NextJS + React Compiler => they don't work together, you should choose only 2 of them.

Well in my experience, they do work together but only if you don't wrap html tags in the components.

But yes, it's a large limitation. It's problematic, since Nextjs is the most popular React framework and the compiler is now a standard react feature.
