HMR

With how wuchale works, a single catalog is often shared between multiple components. That presented a challenge because now updating the catalog to add a single word means invalidating all of the files that use the catalog. This was how wuchale initially worked. While it was fast, it became annoying on a non trivial application because the whole state of the application was lost due to a change in a small component.

Now wuchale integrates with Vite on a deeper level using Vite’s awesome HMR API and it combines it with the reactivity of the framework in use (e.g. Svelte). This way, it delivers granular updates to the specific place where the message was changed. This makes it as if wuchale was never there, while it does its job of extracting and keeping the catalogs up to date. And also live translating using Gemini!

This is only done during development though. No HMR related manipulation is done during production builds or extraction using the CLI.
