What are the best practices to get SSG website with Next-Intl?

[SandraDbn]

Hello,

Our website has been slow for months.
 I did everything NextJS recommended to have SSG / ISR working correctly.
But then, after adding export const dynamic = "error"; I received multiple errors coming from Next-Intl.

One of them was:

Error: Route /[locale]/file/things `dynamic = "error"` couldn't be rendered statically because it used `headers`. See more info here: https://nextjs.org/docs/app/building-your-application/rendering/static-and-dynamic#dynamic-rendering
    at requestLocale (src/i18n/request.ts:5:40)
    at Module.generateMetadata (src/app/[locale]/file/things/page.tsx:40:34)
  3 | import { hasLocale } from 'next-intl';
  4 |
> 5 | export default getRequestConfig(async ({requestLocale}) => {
    |                                        ^
  6 |   // Validate that the incoming `locale` parameter is valid
  7 |   const requested = await requestLocale;
  8 |   let locale = hasLocale(routing.locales, requested) {
  code: 'NEXT_STATIC_GEN_BAILOUT',
  digest: '2705271876'
}

Is there any way to make it work without "requestLocale"?

Thank you very much for your help!

You're probably looking for this: Static rendering.

It's currently unfortunately a bit more cumbersome to set up than I'd like, but a simpler solution should be available in the near future—I hope to have more to share on this soon!

I followed this page:
https://next-intl.dev/docs/getting-started/app-router/with-i18n-routing#static-rendering
After multiple edits (even though the errors are unclear), checking each page one by one, and comparing them to the documentation, it finally works. 🥳

This page on NextJS is also very helpful: https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config
And const export dynamic="error" is essential.

Thanks @amannn for you help, we answered at the same time!
And thank you for Next-Intl 🙌

Great to hear that you got it working! 🙌

Yeah, it's really more cumbersome than I'd hope for currently, should be easier soon 🤞
