Show HN: Wuchale: Protobuf-like internationalization from plain code

1 K1DV5 0 8/27/2025, 3:06:59 PM wuchale.dev ↗

If you, like me, are put off by the huge effort required to add i18n to your web app (Svelte/React/SolidJS), let alone make it performant, then this is for you. I worked on this exact issue over the summer. Where it mainly differs is two things:

1. It lets you keep your code as-is: <p>Hello</p> stays like that.

2. It adds almost zero bundle overhead by just putting the messages in arrays: ['Hello']. Accessed by indices, like Protobuf, no keys, and no function-for-each-message.

Bonus: it can optionally auto-translate with Gemini + HMR in different languages during dev!

Feedback always welcome!
