~⚠️ I lazily created this PR from Github directly as I don't have a local build of next.js on my current machine.
If ever linting does not pass, I will update this later today (sorry for the noise).
EDIT: it does not, I will update this PR shortly.~
Came across this [Slack thread](https://vercel.slack.com/archives/C02F56A54LU/p1642206518128400). Update the docs about adding `locale` string in `getStaticPaths` docs.

* Merge multiple log statements
It is inefficient to use multiple console.log satements, and if something is logged to the console in the middle of execution, it will be in the center of the text, making it hard to read.
This pull request merges multiple console.logs into one.
In addition, it reduces the bundle size.

In order to turn the API Routes docs more clear about the file extensions when using `pageExtensions`.
I know that it was already explained [here](https://nextjs.org/docs/api-reference/next.config.js/custom-page-extensions).
But just think about the DX: If a developer have a trouble with an API endpoint not working properly should it check it on custom-page-extensions page or api-routes page itself??

Fixes#36823Closes#33084
The issue is caused by the `isLocalURL` function only checks if a URL starts with `/`, `#` or `?`. So a URL that starts with `.` will not be considered a "local URL". The PR fixes that by introducing a new util function `isAbsoluteUrl` that is fully compliant with [RFC3986](https://tools.ietf.org/html/rfc3986#section-4.3).
This PR removes the not-very-helpful stack trace when sass is being used but the npm package is not installed. Fixes#13975
- Fix behavior to show the modified error message if either node-sass OR sass is missing
- dispose of stack trace if the condition above passes
- update the error link to [err.sh](https://err.sh/next.js/install-sass) equivalent
- update the relevant test to verify the stack trace is omitted and to account for the new link

## Documentation
The purpose of this PR is to enable Trusted Types compatibility in Webpack. When the app is run in development mode, Webpack is currently set to use an [eval-source-map](5a16b1a26f/packages/next/build/webpack/config/blocks/base.ts (L33)). This source map involves passing raw strings to `eval()` calls, which raise Trusted Types violations. The solution to this problem is to set `webpack5Config.output.trustedTypes` in the Webpack config. As shown in the documentation [here](https://webpack.js.org/configuration/output/#outputtrustedtypes), setting this value to a string will create a Trusted Types policy with the specified name. By creating a policy within Webpack, the raw strings passed to the `eval()` calls will be promoted to be of type `TrustedScript`. The issue where this was addressed in Webpack can be found [here](https://github.com/webpack/webpack/issues/14075).
### Note:
The policy name that is set in the Webpack config is currently `nextjs#bundler`. Once it is released to the public and application developers begin using it, it may be harder to change the value since any application developers with a custom policy name allowlist would now need to update their next.config.js headers to allow this new name. Thus, a good name should ideally be determined before this pull request is merged. The reason that `nextjs#bundler` is preferred over `nextjs#webpack` is in case Next.js moves to a different bundler in the future. Having a generic name would allow for application developers to keep their next.config.js file the same after the bundler switch has occurred. If a different name is preferred, feel free to comment what that would be.
The code was tested in a sample application to ensure it behaved as expected.

Hi, this signature confused me a bit when I was porting it in typescript. Turns out there's dead code: there's no Error object passed to this function. Details of this signature are in this answer: https://stackoverflow.com/a/56291567/2123547, and in `@types/express-server-static-core` it is `listen(port: number, callback?: () => void): http.Server;`.

We added custom _app as server component support in #33149, but we found it's pretty confusing on usage like support it both server component pages and regular pages at the same time for having similar layout purpose.
When using the _app.server and _app at the same time, applying them into proper places become more confusing.
In that case, we decide to make _app.js can't be a server component, and you can still keep all the existing thing there. And also you don't need to think of the corresponding APIs of custom _app in RSC

_Hello Next.js team! First PR here, I hope I've followed the right practices._
### What's in there?
It has been decided to only support the following uses cases in Next.js' middleware:
- rewrite the URL (`x-middleware-rewrite` response header)
- redirect to another URL (`Location` response header)
- pass on to the next piece in the request pipeline (`x-middleware-next` response header)
1. during development, a warning on console tells developers when they are returning a response (either with `Response` or `NextResponse`).
2. at build time, this warning becomes an error.
3. at run time, returning a response body will trigger a 500 HTTP error with a JSON payload containing the detailed error.
All returned/thrown errors contain a link to the documentation.
This is a breaking feature compared to the _beta_ middleware implementation, and also removes `NextResponse.json()` which makes no sense any more.
### How to try it?
- runtime behavior: `HEADLESS=true yarn jest test/integration/middleware/core`
- build behavior : `yarn jest test/integration/middleware/build-errors`
- development behavior: `HEADLESS=true yarn jest test/development/middleware-warnings`
### Notes to reviewers
The limitation happens in next's web adapter. ~The initial implementation was to check `response.body` existence, but it turns out [`Response.redirect()`](https://github.com/vercel/next.js/blob/canary/packages/next/server/web/spec-compliant/response.ts#L42-L53) may set the response body (https://github.com/vercel/next.js/pull/31886). Hence why the proposed implementation specifically looks at response headers.~
`Response.redirect()` and `NextResponse.redirect()` do not need to include the final location in their body: it is handled by next server https://github.com/vercel/next.js/blob/canary/packages/next/server/next-server.ts#L1142
Because this is a breaking change, I had to adjust several tests cases, previously returning JSON/stream/text bodies. When relevant, these middlewares are returning data using response headers.
About DevEx: relying on AST analysis to detect forbidden use cases is not as good as running the code.
Such cases are easy to detect:
```js
new Response('a text value')
new Response(JSON.stringify({ /* whatever */ })
```
But these are false-positive cases:
```js
function returnNull() { return null }
new Response(returnNull())
function doesNothing() {}
new Response(doesNothing())
```
However, I see no good reasons to let users ship middleware such as the one above, hence why the build will fail, even if _technically speaking_, they are not setting the response body.
