fix scroll restoration bug
changed key from index to random string, to be inconsistent with session storage when reloading
Co-authored-by: JJ Kasper <jj@jjsweb.site>
Hello! Thanks for making next.js so great.
## Bug
Right now, these types give false confidence. These `key`s are treated as though [a value is defined for _every_ string](https://dev.to/sarioglu/avoiding-unintended-undefined-values-while-using-typescript-record-4igo). However, given an arbitrary request, a particular cookie or query param could be `undefined`.
For example, when building an `/api` endpoint, the code might look like this:
```ts
import type { NextApiRequest, NextApiResponse } from "next"
export default function handler(req: NextApiRequest, res: NextApiResponse) {
// According to the old types, `value` is a string
const value = req.cookies.value
// Type-checking passes but leads to a runtime error when no `value` cookie is provided in the request
// Uncaught TypeError: Cannot read property 'toLowerCase' of undefined
value.toLowerCause()
// ...
}
```
By using `Partial`, TypeScript now knows that these objects don't have values defined for every `key` and accessing a given `key` might resolve to `undefined`.
---
The only obvious error this caused within this repo was on line 333 of the same file. For better or worse, I ended up casting that cookie value to a `string`. There's a series of `if` statements before it that, I guess, are guaranteeing that it's truly a string. Potentially, that stretch could be refactored such that TypeScript _knows_ it's a string.
Also, I tried to follow the contributing guidelines. However, running `yarn types` kicked out a bunch of errors about overwriting files:
```
$ yarn types
yarn run v1.22.10
$ lerna run types --stream
lerna notice cli v4.0.0
lerna info Executing command in 2 packages: "yarn run types"
@next/env: $ tsc index.ts --declaration --emitDeclarationOnly --declarationDir types --esModuleInterop

next: error TS5055: Cannot write file '/Users/mbrandly/code/next.js/packages/next/dist/build/index.d.ts' because it would overwrite input file.
next: error TS5055: Cannot write file '/Users/mbrandly/code/next.js/packages/next/dist/build/webpack/plugins/build-manifest-plugin.d.ts' because it would overwrite input file.
...
...
...
```
Let me know if there's anything I can improve here! Thanks again.
Adds the `hmr/hotModuleReplacement.js` file to the compiled output
that is used in
`packages/next/build/webpack/plugins/mini-css-extract-plugin.ts`.

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).

## 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.

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.

This PR deprecates declaring a middleware under `pages` in favour of the project root naming it after `middleware` instead of `_middleware`. This is in the context of having a simpler execution model for middleware and also ships some refactor work. There is a ton of a code to be simplified after this deprecation but I think it is best to do it progressively.
With this PR, when in development, we will **fail** whenever we find a nested middleware but we do **not** include it in the compiler so if the project is using it, it will no longer work. For production we will **fail** too so it will not be possible to build and deploy a deprecated middleware. The error points to a page that should also be reviewed as part of **documentation**.
Aside from the deprecation, this migrates all middleware tests to work with a single middleware. It also splits tests into multiple folders to make them easier to isolate and work with. Finally it ships some small code refactor and simplifications.
Hello,
This is an iteration after first work at https://github.com/vercel/next.js/pull/36478.
What that PR missed is a way to just get a cookie value. Well, this PR adds two new things:
`cookies.get` returns the cookie value that could be `string | undefined`:
```js
const response = new NextResponse()
response.cookies.set('foo', 'bar', { path: '/test' })
const value = response.cookies.get('foo')
console.log(value) // => 'bar'
```
Additionally, if you want to know all the cookie details, you can use `cookies.getWithOptions`:
```js
const response = new NextResponse()
response.cookies.set('foo', 'bar', { path: '/test' })
const { value, options } response.cookies.getWithOptions('foo')
console.log(value) // => 'bar'
console.log(options) // => { Path: '/test' }
```
This PR changes the experimental `layout=raw` images to use the native lazy loading behavior (as opposed to the IntersectionObserver).
This will (eventually) lead to smaller client bundles and faster image loading since there is no JS needed to load the image.
However, we'll lose the `lazyRoot` and `lazyBoundary` behavior since those are specific to the IntersectionObserver implementation.
This fixes the interop default from https://github.com/vercel/next.js/pull/36877 on the jest `object-proxy` as it currently causes the below error when running tests in our `with-jest` example:
```sh
TypeError: 'get' on proxy: property '__esModule' is a read-only and non-configurable data property on the proxy target but the proxy did not return its actual value (expected 'true' but got 'false')
```

## What's in there?
Partially fixes https://github.com/vercel/edge-functions/issues/82
Relates to #36715
Our webpack plugin for middleware leverages static analysis to detect Dyanamic code evaluation in user `_middleware.js` file (and depedencies). Since edge function runtime do not allow them, the build is aborted.
The use of `Function.bind` is considered invalid, while it is legit. A customer using `@aws-sdk/client-s3` reported it.
This PR fixes it.
Please note that this check is too strict: some dynamic code may be in the bundle (despite treeshaking), but may never be used (because of code branches). Since this point is under discussion, this PR adds tests covering some false positives (`@apollo/react-hook`, `qs` and `has`), but does not change the behavior (consider them as errors).
## Notes to reviewer
I looked for test facilities allowing to download the required 3rd party modules. `createNext()` in production context made my day, but showed two issues:
- `cliOutput` is not cleaned in between tests. While clearance during `stop()` would be annoying, I hope that clearance during `start()` is better.
- if `start()` fails while building, the created instance can never be stopped. This is because we don't clear `childProcess` after `build`.

Implements the first part of #33227
- Applies browserslist to JS transforms when `experimental.browsersListForSwc` is enabled.
- You don't have to use browserslist, there's also `legacyBrowsers: false` which will be the new default in Next.js 13. See #33227 for which browsers and why. `legacyBrowsers` requires `browsersListForSwc: true` to function until it is the default.
```js
module.exports = {
experimental: {
legacyBrowsers: false,
browsersListForSwc: true,
}
}
```
I only implemented the JS part of the RFC, the CSS part should be handled in a follow-up PR.

Currently, if you try the following code while developing with Next.js inside Middleware:
```ts
const url = new URL(MY_URL)
const res = await fetch(url)
```
The app will work as expected, and so will the dom types for TS 4.5+. However when running `next build` or `tsc` typescript fails with:
<img width="837" alt="image" src="https://user-images.githubusercontent.com/4278345/168647502-06b8b223-e0cf-4e8b-9a82-cdac51748789.png">
The types for `node-fetch` have been updated to include `URL` so this PR updates the dependency to fix it.

This new cookies API uses [Map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map) interface, and it's available for `NextRequest` and `NextResponse`.
Additionally, you can pass a specific cookies option as a third argument in `set` method:
```js
response.cookies.set('foo', 'bar', {
path: '/',
maxAge: 60 * 60 * 24 * 7,
httpOnly: true,
sameSite: 'strict',
domain: 'example.com'
}
```
**Note**: `maxAge` it's in seconds rather than milliseconds.
Any cookie manipulation will be reflected over the `set-cookie` header, transparently.

Back in 2019, React released the first version of `use-subscription` (https://github.com/facebook/react/pull/15022). At the time, we only has limited information about concurrent rendering, and #9026 add the initial concurrent mode support.
In 2020, React provides a first-party official API `useMutableSource` (https://github.com/reactjs/rfcs/pull/147, https://github.com/facebook/react/pull/18000):
> ... enables React components to safely and efficiently read from a mutable external source in Concurrent Mode.
React 18 introduces `useMutableSource`'s replacement `useSyncExternalStore` (see details here: https://github.com/reactwg/react-18/discussions/86), and React changes `use-subscription` implementation to use `useSyncExternalStore` directly: https://github.com/facebook/react/pull/24289
> In React 18, `React.useSyncExternalStore` is a built-in replacement for `useSubscription`.
>
> This PR makes `useSubscription` simply use `React.useSyncExternalStore` when available. For pre-18, it uses a `use-sync-external-store` shim which is very similar in `use-subscription` but fixes some flaws with concurrent rendering.
And according to `use-subscription`:
> You may now migrate to [`use-sync-external-store`](https://www.npmjs.com/package/use-sync-external-store) directly instead, which has the same API as `React.useSyncExternalStore`. The `use-subscription` package is now a thin wrapper over `use-sync-external-store` and will not be updated further.
The PR does exactly that:
- Removes the precompiled `use-subscription` introduced in #35746
- Adds the `use-sync-external-store` to the dependencies.
- The `use-sync-external-store` package enables compatibility with React 16 and React 17.
- Do not pre-compile `use-sync-external-store` since it is also the dependency of some popular React state management libraries like `react-redux`, `zustand`, `valtio`, `@xstate/react` and `@apollo/client`, etc. By install
- Replace `useSubscription` usage with `useSyncExternalStore`

`preact/compat` doesn't have `/server.browser` exports, to make it work with latest of next.js:
* use `react-dom/server` to detect if it could opt-in streaming rendering by checking react 18 `renderToPipeableStream` API in short time fix. In long term `preact/compat`should support `/server.browser` that same with react 17.
* Also filed a PR to `next-plugin-preact` to skip chunk-prepending to pages in edge compiler

## Description
This PR implements a new configuration object in `next.config.js` called `experimental.images.remotePatterns`.
This will eventually deprecate `images.domains` because it covers the same use cases and more by allowing wildcard pattern matching on `hostname` and `pathname` and also allows restricting `protocol` and `port`.

## Documentation
There are three Trusted Types violations that are fixed in this PR:
### 1. ban-element-innerhtml-assignments: maintain--tab-focus.ts
The innerHTML assignment here is unsafe as a string is being used that could contain an XSS attack. The solution chosen was to replace the string containing HTML with programmatically-created DOM elements. This removes the Trusted Types violation as there is no longer a string passed in that can contain an XSS attack.
Notes on solution:
- The `<svg>` tag is omitted completely since the original snippet returns fragment.firstChild.firstChild. The first firstChild omits the `<div>`, and the second firstChild omits the `<svg>`, so to remove unnecessary code the created elements start at the foreignObject level.
- The reason createElementNS is used instead of createElement is because the ‘foreignObject’ element is a separate namespace from the default HTML elements. The documentation for this command is found [here](https://developer.mozilla.org/en-US/docs/Web/API/Document/createElementNS).
The code was tested to be equivalent by rendering both the original code and the re-written code in a browser to see if they evaluate to the same thing in the DOM. The DOM elements styles were then compared to ensure that they were identical.
### 2. ban-window-stringfunctiondef: packages/next/lib/recursive-delete.ts
The setTimeout function caused a Trusted Types violation because if a string is passed in as the callback, XSS can occur. The solution to this problem is to ensure that only function callbacks can be passed to setTimeout. There is only one call to the sleep function and it does not involve a string callback, so this can be enforced without breaking the application logic. In the process of doing this, promisify has been removed and the promise has been created explicitly.
The code was tested in a sample application to ensure it behaved as expected.
### 3. ban-window-stringfunctiondef: packages/next/client/dev/fouc.ts
This file also uses setTimeout, so the call was wrapped in a `safeSetTimeout` call that specifies that the callback argument is not a string.

## Documentation
There is one tsec violation that is fixed in this PR:
### 1. ban-script-src-assignment: route-loader.ts
XSS can occur with the line script.src = src in appendScript(src, script) if src can be controlled by a malicious user. From tracing through the code, it was determined that src comes from the function `getFilesForRoute(route)`. The behaviour of this function differs depending on the environment (development vs. production), but in both cases the function will construct strings that lead to valid file paths. These strings depend on two variables: `assetPrefix` and `route`, but due to the nature of the constructed strings it was determined that the scripts here are safe to use. Thus, the solution was to promote these strings to `TrustedScriptURL`s. This is the Trusted Types way of declaring that the script URL passed to the DOM sink is safe from DOM XSS attacks.
To create a `TrustedScriptURL`, a policy needs to be created. This policy was put in its own file: `client/trusted-types.ts`. This policy has the name `nextjs`. If this name should be changed to something else, feel free to change it now. However, 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.
The code was tested in a sample application to ensure it behaved as expected.
Fixes#36643

Follow-up to https://github.com/vercel/next.js/pull/36527 this adds falling back to the wasm swc build when loading the native bindings fails so that we don't block the build on the native dependency being available.
This continues off of https://github.com/vercel/next.js/pull/33496 but does not add a postinstall script yet and only downloads the fallback when the native dependency fails to load.
* Use flushed effects to generate styled-jsx styles insted of gIP by default
* ensure styles are flushed inside the default getInitialProps

- improve the message for importing node builtin module on edge runtime
- fix to show the message on overlay of error browser with `next dev`
- fix https://github.com/vercel/next.js/issues/36237
The message is NOT shown when using edge runtime (not middleware) since I cannot find a way to detect a webpack compilation is for edge runtime.
