For RSC server layer so far we bundle all dependencies, ESM format is the better one rather than CJS to analyze and tree-shake out the unused parts. This PR changes pick the condition names that are in ESM format first for server layer.
Also fixes the misorder of condition names of edge runtime, `conditionNames` should only contain either ESM or CJS, previously the main fields are mixed with conditon names which is not expected for webpack, we separate them now.
Since we're picking ESM instead CJS now, the error of require `exports * from` doesn't exist anymore, but if you're using a CJS dependency which require a ESM package, it will error. This is the existing behavior for our webpack configuration but could happen on server layer bundling
Other related changes:
* Imports are hoisted in ESM, so migrate`enhanceGlobals` to a imported module
* Use `...` to pick the proper imports by import expression, and prefer the `react-server` / `edge-light` condition names for corresponding cases
* Remove edge SSR duplicated `middleware` export checking
This makes sure that if `revalidateTag` is called in a Server Action, the client router cache and prefetch cache are invalidated correctly so following navigations won't reuse the cache that might hold stale data.
Similar case for `revalidatePath`. I left a TODO where we can't just invalidate the subtree under the revalidate paths because of current implementation limitations. To ensure correctness, we just do the same as `revalidateTag`.
When twitter metadata is not provided but opengraph metadata is, fill the opengraph basic information for twitter metadata.
Twitter card can't be displayed if there's no information from twitter meta tags, at least the `twitter:card`. We fill the `title` `description` and `images` these 3 overlapped properties from opengraph image so they can be displayed properly
Closes NEXT-1111
This starts the process of moving the rendering logic for pages into the
bundle. The `render` method on the module now provides the same
capability as the underlying `renderHTML` method available on the
`NextNodeServer`. In the next few change sets, more layers of the
rendering pipeline will shift into the bundled code, removing them from
the main boot path.

## What?
Anytime you open a Next.js application that doesn't have a `favicon.ico`
you'll notice `/_error` is being compiled because the browser requests
`favicon.ico`. This PR ensures the 404 page is not compiled in
development for that request. It helps a little with compilation speed.

Updates to not throw the dynamic server error inside of the patched
fetch as it's typical for fetch errors to be caught and handled and this
error is not meant to be caught by users. This instead throws it during
rendering so we can ensure we catch it instead of users.

## What?
Recently I've been using these hello-world tests quite often to get the baseline traces out for `pages` and `app`.
Adding them to the repo so that I don't have to recreate / stash them all the time.
This field is no longer needed. Although removing it might cause
unnecessary styles being included that could be tree-shaken potentially,
it solves a more critical issue of missing CSS resources: since now CSS
import can be "hoisted" to its parent entry (e.g. a layout), we can't
simply get all used CSS resources from the "leaf entry" (e.g. a page).

This PR fixes a couple of categories of CSS issues in App Router, that
come from the same root cause.
### 1. Duplicated styles being loaded in different layers
This issue has been described in
https://github.com/vanilla-extract-css/vanilla-extract/issues/1088#issuecomment-1563931144.
If a CSS module (or a global CSS) is referenced in multiple layers (e.g.
a layout and a page), it will be bundled into multiple CSS assets
because each layer is considered as a separate entry.
<img width="1141" alt="CleanShot-2023-05-26-GoB9Rhcs@2x"
src="https://github.com/vercel/next.js/assets/3676859/8e0f5346-ee64-4553-950a-7fb44f769efc">
As explained in that issue, we have to bundle all CSS modules into one
chunk to avoid a big number of requests.
### 2. CSS ordering issues (conflicts)
This is likely causing https://github.com/vercel/next.js/issues/48120.
When the layer-based bundling and ordering logic applies to CSS, it can
potentially cause non-deterministic order. In this example, button A in
the layout should be in blue. However when button B is imported by the
page, button A becomes red. This is an inconsistent experience and can
be hard to debug and fix.

### What?
This test case was never passing and accidentally enabled for Turbopack.
We could disable the whole test suite, but since only one test case is
affected we can also disable only that one.
## What?
Currently we use the initial compile to add entrypoints that we know are
going to be used in the application. For example the Next.js runtime,
`react`, `react-dom`, and such. While this was the right default when
Next.js only had `pages`, it's no longer true when both `pages` and
`app` exist. E.g. when you're working on a page using App Router we'd
still compile `pages/_app`, `pages/_document`, and `pages/_error` even
though those would not be used. In case of larger applications (e.g.
Vercel's application) this would mean thousands of extra modules being
compiled even though you don't need them for the page you're looking at.
Similarly we'd compile the Next.js runtime for App Router even when
you're only using `pages`.
This PR changes the handling to only compile the entries that are needed
for the current set of visited pages (on-demand-entries). If that set
only includes `app` entrypoints then the `pages` related files will be
excluded. If the set contains both `app` and `pages` both will be
included. Similarly for `amp`, if you don't use `amp: true` / `amp:
hybrid` the development runtime will not be compiled.
📔 Note: This is specifically for webpack, Turbopack already compiles
everything needed lazily so it didn't have this limitation.
#### Before
```
- event compiled client and server successfully in 1079 ms (306 modules)
- event compiled client and server successfully in 155 ms (306 modules)
```
With opening `/`:
```
- event compiled client and server successfully in 1118 ms (306 modules)
- event compiled client and server successfully in 157 ms (306 modules)
- event compiled client and server successfully in 599 ms (486 modules)
```
Total: 1.874ms (Note: This number is much higher when `pages/_app`
imports many modules).
#### After
```
- event compiled client and server successfully in 118 ms (20 modules)
- event compiled client and server successfully in 65 ms (20 modules)
```
📔 Note: opening the page then causes the Next.js / React runtime to be
compiled ofcourse
```
- event compiled client and server successfully in 115 ms (20 modules)
- event compiled client and server successfully in 57 ms (20 modules)
- event compiled client and server successfully in 1137 ms (361 modules)
```
Total: 1.309ms (Note: This number is not affected by`pages/_app`
importing many modules).
## How?
We can only apply this optimization after we've looped over the list of
on-demand entries, as that has the required metadata. Hence why I went
with deleting the keys for each respective type of entrypoint (`pages`,
`app`, `amp`).

This breaks up some of our longest running tests which allows more
parallelizing of the tests. This also moves turbopack tests filtering
back to an allow list as it is running a lot of unrelated tests
currently which isn't ideal. We should only be running against tests
that are explicitly testing turbopack e.g. build tests should not be
duplicated in the turbopack group.

## Problem
Relative hash/query handling in `next/link` (e.g. `<Link
href="#hello">`) is broken in App Router, especially if you're on a
nested route.
This wasn't a problem in `/pages` because the href always get fully
resolved in `<NextLink>`; i.e. if you have `<Link href="#hash" />` on
`/hello`, it'll resolve the href to `/hello#hash` and use that
everywhere.
However, in App Router, `<Link>` no longer uses the current location to
resolve the href:
5451564f36/packages/next/src/client/link.tsx (L450-L457)
Therefore navigating with `new URL(href, location.origin)` will skip the
current path and always apply the relative hash/query to the _root_
route:
5451564f36/packages/next/src/client/components/app-router.tsx (L208-L215)
## Solution
Not 100% sure if this is the best solution, but since `app-router` is
already reading `window.location`, I'm using `location.href` as the base
URL to resolve the href.
I grep'd for `location.origin` and checked other callsites; seems like
only `app-router` deals with user specified hrefs.

## Test Plan

```

This adds new `build and test` and `build and deploy` workflows in favor
of the existing massive `build, test, and deploy` workflow. Since the
new workflows will use `pull_request_target` this waits to remove the
existing workflow until the new one is tested.
While testing this new workflow flakey behavior in tests have also been
addressed. Along with the new workflow we will also be leveraging new
runners which allow us to run tests against the production binary of
`next-swc` so this avoids slight differences in tests we've seen due to
running against the dev binary.
Furthermore we will have a new flow for allowing workflow runs on PRs
from external forks which will either require a comment be checking a
box approving the run after each change or a label added by the team.
The new flow also no longer relies on `actions/cache` or similar which
have proven to be pretty unreliable.
Tests runs with the new workflow can be seen here

This exports the named exports from the user's page route file and
exports a new `routeModule` stub. This stub will be the new rendering
mechanism used for pages within `pages/` and will serve to allow us to
deprecate large chunks of the server code to instead live within the
pages entrypoints.
TLDR;
- Route Modules now accept a `definition` so that they have their full
route definition
- Exports are now hoisted from the userland module by name to prevent
name collisions
- A new `PagesRouteModule` stub was added that will in the future
contain all the pages rendering logic

**eslint[@next/next/no-before-interactive-script-outside-document](https://nextjs.org/docs/messages/no-before-interactive-script-outside-document)**
> `next/script`'s `beforeInteractive` strategy should not be used outside of `pages/_document.js`.
## How?
- Possibility of pathname starts with "/" on OS X and Linux, so added condition to check file path starting with "/"

Since the static metadata routes should always be static that can be
optimized, they should be marked as default runtime (or basically no
runtime). This PR change the runtime detection, if it's a static
metadata route file, its runtime will be erased.
So that it won't be picked up by `edge-app-route-loader` and then by
`next-image-loader` which emits the unexpected static file
Fixes NEXT-1238
If using Server Actions on the client layer without enabling the
`serverActions` feature, the build should error. Add a test case to
ensure #50199 works.
Since there is no longer a limitation that requires us to static analyze
`process.env`, this PR removes it from the build process and updates the
corresponding documentation.
