Replace `url.parse` and `url.resolve` logic with whatwg `URL`, Bring in a customized `format` function to handle the node url objects that can be passed to router methods. This eliminates the need for `url` (and thus `native-url`) in core. Looks like it shaves off about 2.5Kb, according to the `size-limits` integration tests.
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.

Removed Option to enable `ReactProductionProfiling` from configuration and added a CLI switch for the same.
Users can now do `next build --profile` to enable react production profiling.
Also added a warning to notify users about the performance impact
Fixes: #14688
This adds additional checks against the routeKeys used to build the named regexes for dynamic routes to ensure they follow PCRE rules for named capture groups

Discovered while working on https://github.com/vercel/next.js/pull/14848
when asPath is the same but href is different it should use `replaceState` instead of `pushState`, so that browser back/forward behavior is preserved. Currently it's comparing a path that includes basepath with one that excludes it, so `pushState` is always used. This makes sure the behavior is the same as when running next.js without a basepath
Currently following links are broken when using `basePath`:
```jsx
// pages/hello.js
<Link href="#hashlink">
<a id="hashlink">Hash Link</a>
</Link>
```
with `basePath: '/docs'`, this will navigate to `/docs/docs/hello#hashlink` instead of `/docs/hello#hashlink`
I have a further optimization that builds on this branch that removes `url.parse` and `url.resolve` in favor for `new URL()` in router and link. Will PR when this gets merged.
This updates the scroll position saving to occur as the scroll position changes instead of trying to do it when the navigation is changing since the `popState` event doesn't allow us to update the leaving history state once the `popState` has occurred.
The order of events that was previously attempted to save scroll position on a `popState` event (back/forward navigation)
1. history.state is already updated with state from `popState`
2. we replace state with the currently rendered page adding scroll info
3. we replace state again with the `popState` event state overriding scroll info
Using this approach the above event order is no longer in conflict since we don't attempt to populate the state with scroll position while it's leaving the state and instead do it while it is still the active state in history
This approach resembles existing solutions:

Since the no-op rewrite is a valid rewrite used to check pages/assets before adding a 404-rewrite this makes sure we don't show the rewriting to auto-export dynamic pages warning from it
Closes: https://github.com/vercel/next.js/issues/14736
This makes sure to base64 encode the `.env*` file contents before passing them in the URL for the serverless-loader since `!` is a special character in this case which can cause webpack to fail to build
Closes: https://github.com/vercel/next.js/issues/14749
Avoid trailing slashes on urls that look like files. The redirect for `trailingSlash: true` will now look like:
```
Redirects
┌ source: /:path*/:file.:ext/
├ destination: /:path*/:file.:ext
└ permanent: true
┌ source: /:path*/:notfile([^/.]+)
├ destination: /:path*/:notfile/
└ permanent: true
```
The default still looks like:
```
Redirects
┌ source: /:path+/
├ destination: /:path+
└ permanent: true
```
After this gets merged, I have a few optimizations planned on the normalization code that should reduce the client bundle a little and that consolidates the `trailingSlash` and `exportTrailingSlash` options
This updates `fetchNextData` to re-use the `getDataHref` function from `page-loader` which has more verbose handling to ensure the correct `/_next/data` URL is built. Re-using this logic ensures the `/_next/data` URL can still be built even when a mismatching `href` and `as` value is provided to `next/link`.
This also fixes a case in `getDataHref` where optional values that weren't provided would fail to build the data href since the check requiring the param be present while interpolating the route values hasn't been updated to allow missing params for optional values.
An additional test case has been added to the prerender suite to ensure the `/_next/data` URL is built correctly when mismatching `href` and `as` values are provided

Add tests and fix for when the url contains query parameters.
`router` now uses the same method for formatting url+as pair as `Link`, will be able to share code after https://github.com/vercel/next.js/pull/14633 is merged
We've been meaning to change this code for a while 👍
- Changed the name from spr to incremental
- Changed the code to be a class instead of using module scope variables
Closes [13709](https://github.com/vercel/next.js/issues/13709).
The solution works, **(tested and confirmed with true and false flags with the latest next version)** though I am quite sure this is not the most elegant and proper way to implement it. I have spent the good part of yesterday and today's morning in order to make it more generic but since it's my first time working with anything related to webpack I have struggled miserably. Last, but not least I'm unsure if this is the most proper naming for the flag.
Please, let me know what you want me to change and I'll get it done asap.
Noticed while trying to get https://github.com/vercel/next.js/pull/14442 tests to pass. The backslash needs to be double escaped in snapshots. Forward slashes aren't escaped, maybe that was the assumption when this test was written?
* Avoid adding basePath when it's not needed
When using the `basePath` setting, on pages with params it will fire a router change. This will pass the url pathname in the `as` param using the `getUrl()` function. This means the `as` path will be sent through already including the `basePath`, leading to `/basePath/basePath/path` which will cause the router to throw an error.
* lint
* Add test case and ensure removal
* Make sure to re-add before changeState

Warn users and revert their `devtool` when they manually change the `devtool` in development mode. For this addition, I check to ensure the `devtool` is custom (i.e. different than what is set by Next) and has a value (`false` is fine as a custom `devtool`!).
As described in [this issue (13963)](https://github.com/vercel/next.js/issues/13963), changing the `devtool` in development mode can cause issues with performance.
Fixes#13963
This fixes the `basePath` not being used when making requests for the `react-dev-overlay`. We might want to pass down the `basePath` to the overlay instead of relying on the `process.env` injection although may be fine this way, will defer to @Timer for preferred way to pass this value to the dev-overlay

Noticed this while reviewing https://github.com/vercel/next.js/pull/14376. After having done https://github.com/vercel/next.js/pull/13699, this code didn't feel right to me:
```js
function prepareRoute(path: string) {
path = delBasePath(path || '')
// this /index rewrite is problematic, it makes pages/index.js
// and pages/index/index.js point to the same thing:
return toRoute(!path || path === '/' ? '/index' : path)
}
```
Added a nested index page to the prerender tests and found it was rendering the `/` route on navigation. This uncovered 2 more places around the dataroute where the index path was not translated correctly.
**edit:**
Just to note that there was nothing wrong with https://github.com/vercel/next.js/pull/14376, the issue was already there, I just noticed it while reading that PR
Noticed while working on https://github.com/vercel/next.js/pull/14400 that the optional catch-all handling was missing in `namedRegex`.
This whole file also seemed quite regex heavy so I took a look at the overall logic and changed a few things. It worked by regex escaping the whole route then unescape the dynamic parts. I changed it to only regex escape the static parts, this eliminates unnecessary back and forth escaping. It also makes the dynamic parts handling more readable. The whole logic is less reliant on regexes and just uses simple string manipulation to translate the route into a regex, I didn't measure anything but as an effect this should make it more performant.
Updates the way filenames are generated for browser compilation.
Notably:
- All entry bundles now have hashes in production, this includes pages (previously pages used a buildId in the path)
- The AmpFiles no longer depends on hardcoded bundle names, it uses the buildManifest instead (internals)
- All cases where we match the page name from the chunk/entrypoint name now use the same function `getRouteFromEntrypoint` (internals)
- In development we no longer include the "faked" `buildId` set to `development` for page files, instead we just use the `/_next/static/pages` path (was `/_next/static/development/pages`). This was changed as it caused unneeded complexity and makes generating the bundles easier (internals)
- Updated tons of tests to be more resilient to these changes by relying on the buildManifest instead of hardcoded paths (internals)

This corrects the `/_next/data` path generated when using `basePath` with `getStaticProps` in a `pages/index.js` file which was previously stripping the `basePath` without checking if `/index` needed to be appended after stripping. This also adds additional checks to the `basePath` test suite to prevent regressing
