The recommended code for `_middleware.ts` does not work in prod, but does work locally. You need to use `request.nextUrl.pathname` to properly redirect from what I can tell. You also need to have a quick helper function to strip off the `/default` locale at the start of the pathname as we are providing `/en` as a fallback locale.
FWIW - I am pretty new to NextJS. Someone with more experience should probably review this suggestion before merging it. What I can tell you however is that the code as it is in `_middleware.ts` works locally but breaks in prod. To test this out use the code and navigate to `https//www.mysite.com` - it will work as expected on the root url, as this matches `nextUrl.href`. Now try navigating to `https//www.mysite.com/about` and you will be redirected to `https://www.mysite.com/en/https://www.mysite.com/about`.

* Add `async` to middleware docs.
I was reading the docs and got nervous. It looked like middleware didn't support async/await. After digging into the examples I found out it is possible.
Not 100% sure if this is the docs change yahs want, but I thought I'd open a PR just incase.

* Fix ambiguous flags in Dockerfile example
At least with Docker xx this Dockerfile fails to both `adduser` and `addgroup` commands due to ambiguous flags. The error message for example for `addgroup` is:
```
#5 0.292 Option g is ambiguous (gecos, gid, group)
#5 0.292 Option s is ambiguous (shell, system)
```
This PR switches both commands to use the long-format flags. I think they are also more understandable for the readers of the Dockerfile.

In #33968, a warning was added for script tags inserted through the
next/head component. This change unintentionally included
application/ld+json scripts, which shouldn't be triggering the
warnings (as they were originally intended to catch scripts where
loading order or timing could be important). This change adds an
exception for application/ld+json scripts, so they do not log the
warning if they are included through next/head.
We need to make some quick fixes to the Form guide. The PR changes title and meta description.

## Context
Having 3 environments:
- Development: for doing testing
- Staging: for doing UAT testing
- Production: for users
In each environment, the Next.js application makes API calls to the corresponding API gateway:
- Development: https://api-development.com
- Staging: https://api-staging.com
- Production: https://api-production.com
Using `NEXT_PUBLIC_API_URL` for the `baseUrl` of [axios](https://axios-http.com/docs/intro).
Since the `NEXT_PUBLIC_API_URL` is replaced during _build time_, we have to manage to provide the corresponding `.env.production` files for Docker at _build time_ for each environment.
## Solution
Since we are using CI services for dockerization, we could setup the CI to inject the correct `.env.production` file into the cloned source code, (this is actually what we did). Doing that would require us to touch the CI settings.
Another way is using multiple Dockerfile (the former only need to use one Dockerfile), and the trick is copying the corresponding `env*.sample` and rename it to `.env.production` then putting it into the Docker context. Doing this way, everything is managed in the source code.
```
> Dockerfile
# Development environment
COPY .env.development.sample .env.production
# Staging environment
COPY .env.staging.sample .env.production
# Production environment
COPY .env.production.sample .env.production
```
Testing these images locally is also simple, by issuing the corresponding Makefile commands we can simulate exactly how the image will be built in the CI environment.
## How to use
For development environment:
```
make build-development
make start-development
```
For staging environment:
```
make build-staging
make start-staging
```
For production environment:
```
make build-production
make start-production
```
## Conclusion
This example shows one way to solve the three-environment model in software development when building a Next.js application. There might be another better way and I would love to know about them as well.
I'm making this example because I can't find any example about this kind of problem.

I'm getting this warning when running `yarn lint` on the local:
After a quick check, it is caused by the `tailwindConfig` option in the `prettier.config.js` file, added in PR #33614
I guess the reason is because the workspace does not install that plugin.
We can safely remove that option in the example, because it's already [the default location](https://github.com/tailwindlabs/prettier-plugin-tailwindcss):
> By default the plugin will look for this file in the same directory as your Prettier configuration file. However, if your Tailwind configuration is somewhere else, you can specify this using the tailwindConfig option in your Prettier configuration.
The warning is gone after removing that option.
Since the variable name is called `data`, I believe checking `profileData` will always be `undefined`.

Since we're always using `ReadableStream`, we should just get rid of `ResultPiper`.
This also lets us replace things like `bufferedReadFromReadableStream` with a `TransformStream` that does the same thing, so that it's `TransformStream`s all the way down.
Finally, we can get rid of the one-off call to `renderToReadableStream` and just use `renderToStream` whenever we're rendering a concurrent tree.
This commit adds a development mode warning in the console
if you try to include <link rel="stylesheet"> tags in
next/head, e.g.
```
<Head>
<link ref="stylesheet" href="..." />
</Head>
```
The warning message explains that this pattern will not
work well with Suspense/streaming and recommends using a
custom Document component instead.

Instead of branching rendering based on Node.js and browser/web runtimes, we should just use the web version for now, which can run as-is on versions >=16.5.0 of Node.js, polyfilling `ReadableStream` on older versions when necessary.
There are a few potential downsides to this, as React is less able to optimize flushing and execution. We can revisit that in the future though if desired.
This ensures we always transpile optional chaining and nullish coalescing with swc the same as we do [with babel](4812e22992/packages/next/build/babel/preset.ts (L97-L98)) since it can cause issues with webpack even when the node target supports these features.
The specific case this seems to cause issues with webpack is when a value is imported and optional chaining is used on the import value webpack is stripping the optional chaining cc @sokra

Updates all CMS updates to use:
- Tailwind 3 (and the corresponding `tailwind.config.js` and PostCSS changes)
- `remark@14` and `remark-html@15` (and the corresponding ESM breaking changes)
- `date-fns` minor bump
Ensured all CMS examples were:
- Using `next/image`
- Not using `as` for `next/link` (no longer needed)

To help prepare for React 18, I've found myself sharing the updated code snippet of `_document` linked in the [React 18 docs](https://nextjs.org/docs/advanced-features/react-18#react-server-components), which uses a function instead of a class.
This PR updates the Custom Document docs to help prepare for this change, by encourage readers to use the new version, and listing more tangible examples of why you would override `_document` (`lang` on `html`, className on `body`). It also reorganizes some of the caveats and warnings related to `getInitialProps` usage to only be in the single section that applies to it.
These overrides and ejections (`getInitialProps` and `renderPage`) only apply to a subset of the people looking to change document.

Fixes#33536
I was thinking to make `body` optional here instead:
2c6bd1ed1b/packages/next/shared/lib/utils.ts (L262)
But that might result in more errors when not setting the status code correctly. So it's the easiest for us to just recommend `.end()` which `.send()` uses when there is no argument.
