So much amazing feedback on this already. I'm thinking about writing up an RFC to collect all of it and break this down in more detail. Many thanks to everyone who has already shared their opinions!.

@AmirAnvarov I'm actively brainstorming the API for inline messages, but one that I like so far would be an additional useExtracted hook that compiles down to useTranslations. Some benefits:.- No need to manage JSON files.- AI can reason locally within a single module.- No need for naming

With the next-intl course released, I have some time to develop features for the library now. The main topics on the roadmap are:.- Tree-shaking of messages.- AOT compilation of messages.- Inline messages with extraction. Is there something you're particularly excited about?.

Related to this, I added some minor cleanup around this feature in v4.3.5.

A notable feature of this release is the introduction of `next typegen`. If you already use type-safe arguments with 🌐 next-intl, we can now piggyback on the typegen command as another option to programmatically create a declaration file.

@nextjs @tailwindcss @supabase @vercel @codehike_ @resend @lmsqueezy @github @Vimeo I almost went with an off-the-shelf platform so I could focus purely on course content … but none of them felt quite right. Then, on a long train ride back in January, I decided to do a small hackathon to see how far I could get in a few hours, heavily utilizing @cursor_ai.

When I started building 🌐 next-intl, I thought it could solve i18n in Next.js. But I realized it’s a toolkit, not the full stack. That’s why in the course I’ve partnered with:.→ @sanity_io, to manage and localize content.→ @crowdin, to translate & automate with AI. 👇.
