Follow-up to https://github.com/vercel/next.js/pull/17370 this adds mapping of locales to domains and handles default locales for specific domains also allowing specifying which locales can be visited for each domain.
This PR also updates to output all statically generated pages under the locale prefix to make it easier to locate/lookup and to not redirect to the default locale prefixed path when no `accept-language` header is provided.
Follow-up PR to #17370 this adds generating auto-export, non-dynamic SSG, and fallback pages with all locales. Dynamic SSG pages still control which locales the pages are generated with using `getStaticPaths`. To further control which locales non-dynamic SSG pages will be prerendered with a follow-up PR adding handling for 404 behavior from `getStaticProps` will be needed.

This is a follow-up to https://github.com/vercel/next.js/pull/16973 which adds handling for the breaking change in the latest version of css-loader that causes unresolved file references in `url` or `import` to cause the build to fail. This fixes it by adding our own resolve checking and when it fails disabling the `css-loader`'s handling of it.
Fixes: https://github.com/vercel/next.js/issues/17701
Follow-up PR to https://github.com/vercel/next.js/pull/17370 when the path is not prefixed with a locale and the default locale is the detected locale it doesn't redirect to locale prefixed variant. If the default locale path is visited and the default locale is visited this also redirects to the root removing the un-necessary locale in the URL.
This also exposes the `defaultLocale` on the router since the RFC mentions `Setting a defaultLocale is required in every i18n library so it'd be useful for Next.js to provide it to the application.` although doesn't explicitly spec where we want to expose it. If we want to expose it differently this can be updated.
This adds the initial changes outlined in the [i18n routing RFC](https://github.com/vercel/next.js/discussions/17078). This currently treats the locale prefix on routes similar to how the basePath is treated in that the config doesn't require any changes to your pages directory and is automatically stripped/added based on the detected locale that should be used.
Currently redirecting occurs on the `/` route if a locale is detected regardless of if an optional catch-all route would match the `/` route or not we may want to investigate whether we want to disable this redirection automatically if an `/index.js` file isn't present at root of the pages directory.
TODO:
- [x] ensure locale detection/populating works in serverless mode correctly
- [x] add tests for locale handling in different modes, fallback/getStaticProps/getServerSideProps
To be continued in fall-up PRs
- [ ] add tests for revalidate, auto-export, basePath + i18n
- [ ] add mapping of domains with locales
- [ ] investigate detecting locale against non-index routes and populating the locale in a cookie

This makes sure we have the correct `asPath` value to prevent breaking hydration for `getServerSideProps` pages and doesn't re-use the `resolvedUrl` value for the `asPath` and instead creates a separate `resolvedAsPath` value that only removes the `_next/data` prefix from the path. Additional tests have been added in the `getServerSideProps` suite to ensure correct `asPath` with rewrites.
Fixes: https://github.com/vercel/next.js/issues/17113
This continues off of https://github.com/vercel/next.js/pull/17081 and provides this normalized `asPath` value in the context provided to `getServerSideProps` to provide the consistent value since the request URL can vary between direct visit and client transition and the alternative requires building the URL each time manually.
Kept this change separate from https://github.com/vercel/next.js/pull/17081 since this is addressing a separate issue and allows discussion separately.
Closes: https://github.com/vercel/next.js/issues/16407
This normalizes the `asPath` for `getServerSideProps` and `getStaticProps` pages to ensure it matches the value that would show on the client instead of a) the output pathname when revalidating or generating a fallback or b) the `_next/data` URL on client transition.
Fixes: https://github.com/vercel/next.js/issues/16542
To prevent FOUC, discussed in #10557 i need to store information about css file dependencies for chunk. Right now current implementation just throws away everything but js.
Can there be more than one css file in chunk? If no - code will be simplified.
closes#10557
This fixes a client-side file not being transpiled correctly when rewrites are used. The cross browser tests have been updated to make sure there are rewrites so the related code is included and not dead-code eliminated'
Closes: https://github.com/vercel/next.js/issues/16440
This corrects the case where `/index` is used during revalidation for an optional catch-all route and `index` is passed as a param even though it should be undefined. This also adds test cases to make sure the params are normalized correctly
Fixes: https://github.com/vercel/next.js/issues/16366
This interpolates the dynamic values and rebuilds the request URL for fallback SSG pages since the proxy uses the output path for non-prerendered pages on Vercel which can cause inconsistent request URL/`asPath` values for SSG pages. This also adds tests to ensure the `asPath` is correctly updated
Fixes: https://github.com/vercel/next.js/issues/16269
This updates to not automatically append params to the query for rewrites if one or more of the params are already used in the destination's path. No other behavior is being changed and if the user still wants the params in the query after using them in the destination's path they can manually add them like with redirects.
Closes: https://github.com/vercel/next.js/issues/15626
This pull request edits the `BuildManifest` that is sent to `/_document` instead of modifying a single input array to decouple its implementation details.
Optimally, we'd eliminate the `files` key all together.

Since we now use query parameters to pass dynamic route params while routing on Vercel, this makes sure we normalize the request URL before populating the `asPath`
Fixes: https://github.com/vercel/next.js/issues/15879
- Using `namedChunks` where possible, this will also allow for faster access to the chunks as we no longer have to look them up like we did before using `find`
- Using the new asset hooks introduced in the latest webpack beta
- Using the new externals function signature
This updates collecting dynamic route params on Vercel to make sure that missing optional dynamic routes are undefined. Additional tests for this mode have also been added to ensure the params are being collected properly
Closes: https://github.com/vercel/next.js/issues/15579
This adds handling for custom-routes with `basePath` to automatically add the `basePath` for custom-routes `source` and `destination` unless `basePath: false` is set for the route.
