This bumps the babel cache key since we modified the `react-loadable` babel plugin and we don't want any cached versions used since the module names generated in previous cached version won't match the newly expected values.

This ensures we don't attempt prepending the `basePath` for external (http://) `getStaticProps`/`getServerSideProps` redirects. Additional tests to cover this case have been added in the `gssp-redirect` test suites to prevent regression.

This adds support for returning an object from `rewrites` in `next.config.js` with `beforeFiles`, `afterFiles`, and `fallback` to allow specifying rewrites at different stages of routing. The existing support for returning an array for rewrites is still supported and behaves the same way. The documentation has been updated to include information on these new stages that can be rewritten and removes the outdated note of rewrites not being able to override pages.

This adds support for a `has` field to `rewrites`, `redirects`, and `headers` to allow matching against `header`, `cookie`, and `query` values. Documentation and additional tests for the feature is also added in this PR.
Closes: https://github.com/vercel/next.js/issues/22345
A number of changes here. I recommend viewing the diff with the <a href="?w=1">whitespace flag enabled</a>.
- OpenTelemetry is replaced with a custom and lightweight tracing solution.
- Three trace targets are currently supported: console, Zipkin, and NextJS.
- Tracing is now governed by environment variables rather than `--require instrument.js`.
+ `TRACE_TARGET`: one of `CONSOLE`, `ZIPKIN`, or `TELEMETRY`; defaults to `TELEMETRY` if unset or invalid.
+ `TRACE_ID`: an 8-byte hex-encoded value used as the Zipkin trace ID; if not provided, this value will be randomly generated and passed down to subprocesses.
Other sundry:
- I'm missing something, probably a setup step, with the Zipkin target. Traces are captured successfully, but you have to manually enter the Trace ID in order to view the trace - it doesn't show up in queries.
- I'm generally unhappy with [this commit](235cedcb3e). It is... untidy to provide a telemetry object via `setGlobal`, but I don't have a ready alternative. Is `distDir` strictly required when creating a new Telemetry object? I didn't dig too deep here.
As noted, there are a lot of changes, so it'd be great if a reviewer could:
- [ ] pull down the branch and try to break it
- [ ] check the Zipkin traces and identify possible regressions in the functionality
Closes#22570Fixes#22574
This ensures we load `_document` then `_app` and then the page's component in all cases which matches behavior between the serverless target and the default server target. Additional tests to ensure this order is followed has been added to prevent regression.

i confirmed in a personal test repo that this solves the issue of infinite 307s on root level non-default locales :) let me know what else this needs if anything! thanks for the time/help @ijjk ❤️
This picks up on the inlining work in https://github.com/vercel/next.js/pull/20598 to also include webpack loader inlining optimizations.
This includes:
* The dependencies of sass-loader
* resolve-url-loader
And for added benefit:
* babel-plugin-transform-define
* babel-plugin-transform-react-remove-prop-types
style-loader and css-loader didn't inline easily. Perhaps we can come back to these ones.
This ensures we detect domain specific locales and redirect them client-side. Tests have been added in the `i18n` suite to ensure the domain redirect is applied correctly during a client-side navigation
Fixes: https://github.com/vercel/next.js/issues/19174
There's currently two bugs with the font optimization, but we'd really like to ship a stable version.
To unblock the stable release, we're **temporarily** reflagging this. It'll be unflagged on canary again!
This PR removes the modern mode experiment because:
- It does not yield meaningful bundle size wins when compared to other initiatives we've taken
- It's not compatible with webpack 5 (which we're upgrading to)
- It's currently broken and causes most apps to malfunction
- There's no champion currently owning the experiment
We can re-introduce this in the future when we'd like to make it a default for all Next.js apps.
Note: **Next.js still supports Differential Loading (`nomodule`) and does it by default.** This PR strictly removes the experimental modern _syntax_, and does not disable our existing modern/legacy polyfilling.

This fixes a few things related to optional catch-all routes and i18n. The first thing is it ensures the correct data route is generated on the client so that the locale isn't duplicated for an optional catch-all route, the next is it ensures the browser history is updated correctly when only a locale change is occurring, and then it also ensures we handle the locales and normalizing for fallback optional catch-all pages correctly.
Tests have been added to ensure these cases are covered properly and we don't regress on them, these changes were also tested on Vercel [here](https://next-js-bug-i18n-root-params-nybg44l0b.vercel.app/)
Fixes: https://github.com/vercel/next.js/issues/18633
Fixes: https://github.com/vercel/next.js/issues/19059
This ensures we use the `defaultLocale` for a locale domain when rendering non-static pages. Static pages will initially contain the global `defaultLocale` and then be updated on the client since we don't currently prerender a version of the pages for each locale domain.
Closes: https://github.com/vercel/next.js/issues/18970
This upgrades to ncc@0.25.0 and fixes the previous bugs including:
* ncc not referenced correctly in build
* Babel type errors
* node-fetch, etag, chalk and raw-body dependencies not building with ncc - these have been "un-ncc'd" for now. As they are relatively small dependencies, this doesn't seem too much of an issue and we can follow up in the tracking ncc issue at https://github.com/vercel/ncc/issues/612.
* `yarn dev` issues
Took a lot of bisecting, but the overall diff isn't too bad here in the end.
This adds inlining for Babel and the Babel plugins used in next.
This is based to the PR at https://github.com/vercel/next.js/pull/18823.
The approach is to make one large bundle and then separate out the individual packages from that in order to avoid duplications.
In the first attempt the Babel bundle size was 10MB... using "resolutions" in the Yarn workspace to reduce the duplicated packages this was brought down to a 2.8MB bundle for Babel and all the used plugins which is exactly the expected file size here.
This will thus add a 2.8MB download size to the next package, but save downloading any babel dependencies separately, removing a large number of package dependencies from the overall install.
When visiting a non-locale prefixed path (`/hello` instead of `/fr/hello`) we don't trigger locale redirects currently so if another locale is matched we need to ensure this is reset to the `defaultLocale` for rendering to prevent a mis-match on the client and the server.
This also fixes hydration errors from occurring with `asPath` for `getServerSideProps` pages due to `normalizeLocalePath` expecting only a pathname and `asPath` containing `hash` and `query values also.

Fixes: https://github.com/vercel/next.js/issues/18510
This makes sure we don't use invalid `x-now-route-matches` which can occur when `i18n` default locale is visited and a prerendered page is matched. To correct this we first check if we are able to derive the correct params from the URL and then bail on parsing `x-now-route-matches` if we are. Additional test cases are being added in the builder to ensure we don't regress on this

This ensures we provide the current `locale`, `locales`, and `defaultLocale` in the context when rendering the 404 for a blocking SSG page
Fixes: https://github.com/vercel/next.js/issues/18505
This ensures that when using a `pages/404` file with `getStaticProps` that we call `getStaticProps` in `fallback: 'blocking'` mode
Fixes: https://github.com/vercel/next.js/issues/18293
This updates the fallback 404 handling to render the correct 404 page on the client when a 404 is returned from fetching the data route on a fallback page on the client. This prevents us from having to rely on a cache to be updated by the time we reload the page to prevent non-stop reloading.
This also adds handling in serverless mode to ensure the correct 404 page is rendered when leveraging fallback: 'blocking' mode.
Additional tests for the fallback: 'blocking' 404 handling will be added in a follow-up where returning notFound from `getServerSideProps` is also added.
This makes sure the `locales` are passed to `getStaticPaths` and also disables the removing the default locale from the path when the default locale is the preferred header. It also updates tests to ensure the domain redirects are working as expected.
x-ref: https://github.com/vercel/next.js/pull/17370
This makes sure that we detect the correct default locale for domain specific locales since a domain can have a different default locale residing at the root and we need to check this on the client for prerendered/auto-static pages. This also makes sure we disable the built-in redirect handling when on Vercel since it's handled already.
Tests for this are tricky since we need to load the browser with a custom domain which requires editing the host file. Existing tests should ensure this doesn't break non-domain specific locale behavior though. This was also tested manually while testing https://github.com/vercel/vercel/pull/5298
x-ref: https://github.com/vercel/next.js/pull/17370
This makes sure the correct `initialRevalidateSeconds` field is populated in the `prerender-manifest` for non-dynamic SSG pages since they will be inserted into the `initialPageRevalidationMap` under their locale prefixed variant with `i18n` enabled
