## What?
Follow-up to #63665.
Ensures development tests are skipped during the production build run
for Turbopack (i.e. used to create the turbopack-build-tests-manifest).
Adds `pnpm test-dev-turbo` and `pnpm test-start-turbo` (and their
`testonly` equivalent) for running tests.

### What?
Now that @phanect added support for ESM PostCSS config files in PR
#63109 (original issue #34448), PostCSS can use ESM config by default.
It needs to use an `.mjs` extension by default because `create-next-app`
scaffolds CommonJS apps by default.
This will also work with ESM projects which have added `"type":
"module"` in their `package.json`
### Why?
1. To convert one more file to ESM
2. To use the modern format
3. To follow other similar migrations that have taken place in the
Next.js codebase (eg. `next.config.mjs`)
### How?
- Change file extensions from `.cjs` to `.mjs` (change similar to PR
#58380)
- Change module format from CommonJS to ESM
- Add type for the config, for users who enable `checkJs: true` in
`tsconfig.json`
Co-authored-by: Sam Ko <sam@vercel.com>
### What
This is stopgap substitution to webpack's wellknownerrorsplugin. When
webpack compilation hits known errors kind it emits compilation errors
into cli (and dev overlay both) while turbopack currently only emits
into error overlay. PR simply detects if given issue is well known, and
then logs into std.
Probably a long term there should be proper wiring instead; but for now
this allows to make few things work out of the box.

Instead change the require of postcss.config.js in /path/to/my/repo/components/node_modules/next/dist/lib/find-config.js to a dynamic import() which is available in all CommonJS modules.

Even though PostCSS itself [supports ESM and TypeScript configuration

Next.js itself does not (because of `next/lib/find-config`):

#62980 migrated `examples/basic-css` to use app router. A handful of our
create-next-app tests use this example when asserting the correct
project files are created, so we were asserting on a pages file existing
rather than an app dir page. This PR updates those tests.

### What?
* upgrades turbopack for `getResolve` in webpack loaders
* add missing resolve-url-loader to turbopack for full sass support
Closes PACK-2634
## Description
Refactor the [Next.js
CLI](https://nextjs.org/docs/app/api-reference/next-cli) to use
[commander](https://github.com/tj/commander.js) instead of
[arg](https://github.com/vercel/arg).
## Why?
- Auto-generated, properly formatted help command + output. With `arg`,
much of the help commands were manually added via a single
`console.log`, causing deviations over time.
- Ergonomic, ease of adding new subcommands and rules
## Breaking Changes
- Update the experimental `next experimental-compile` and `next
experimental-generate` build commands in favor of `next build
--experimental-build-mode=compile/generate`

## What?
Migrates the Sass support tests from `test/integration` (legacy test
suite) to `test/e2e`, this way all these tests run against both
development and production, whereas previously most of them would only
run against production.
This is helpful as it ensures the tests are running against Turbopack
too, which is highlighting some missing features in Sass support for
Turbopack.
I've had to rewrite most of the tests to check against the actual
rendered output in the browser instead of CSS output in the `.next`
folder, the majority of these now run regardless of implementation
details.

This ensures our dynamic routes that have the same specificity as
`_next/static/:path*` don't get matched unexpectedly when the
`_next/static` asset doesn't exist. We were holding off on making this
change explicit due to compatibility concerns but these are no longer a
concern and the unexpected matching is more of a concern.

## What?
Groups together the scss tests. I'm working on refactoring these to use
`test/e2e` instead as many tests currently only run during builds and we
want to make sure these Sass tests run for Turbopack (which is dev only
currently) to catch bugs.

### What?
The [create-next-app
documentation](https://nextjs.org/docs/app/api-reference/create-next-app#non-interactive)
under API reference says that;
> Further, you can negate default options by prefixing them with --no-
(e.g., --no-eslint).
When I tried to use --no-import-alias, I thought that it would
automatically use the default alias (@/*), but it does not.
### Why?
Each option has --no prefix control but import-alias has no --no prefix
control to give default value to program.
In an [Interactive](https://nextjs.org/#interactive) approach, the user
can select a prompt; `Would you like to customize the default import
alias (@/*)? No / Yes.` If the user selects no, then the default alias
is applied with @/*.
### How?
Implementing a condition solve the problem for general purpose. If
arguments includes `--no-import-alias` then the importAlias section
automatically apply the default value.

### Why?
I really dislike the way `.chain` works right now, it shouldn't mutate
the `BrowserInterface`, this PR changes it so it's just a pure chain
without weird side effects.
One example with the current version (before this PR):
```
const el = browser.elementByCss('#version-2')
await el.text()
// throws
await el.text()
```
### Additional Changes
- removes selenium (which is completely unused)
- updates playwright
- makes the playwright tracing not error all the time
Previously, this error was confusing because it made it sound like the
`sizes` prop was missing. This was because the default value of `sizes`
is `100vw` so the previous code couldn't tell the different between
implicit vs explicit `100vw`.
This PR changes the code to read the input value from the `sizes` prop
and prints a better warning.
Fixes NEXT-2441
To ensure that we properly cache data for routes that change based on `Next-URL` (which is used for route interception), this adjusts how we set the `Vary` header to conditionally include `Next-URL`.
The `Next-URL` request header only impacts the response for routes that are intercepted. When we detect that path we're handling could be intercepted, we add `Next-URL` to the vary. This signals in #61235 to prefix these cache entries with `nextUrl` if the response might vary based on it.
Closes NEXT-2398
### Why
The `process/browser` lib was imported and being transformed, but
`process.browser = true` turns to `true = true` that causes the
compilation error, we need to exclude them from certain compilation
layers

## History
Previously, we added support for `squoosh` because it was a wasm
implementation that "just worked" on all platforms when running `next
dev` for the first time. However, it was slow so we always recommended
manually installing `sharp` for production use cases running `next
build` and `next start`.
Now that [`sharp` supports
webassembly](https://sharp.pixelplumbing.com/install#webassembly), we no
longer need to maintain `squoosh`, so it can be removed. We also don't
need to make the user install sharp manually because it can be installed
under `optionalDependencies`. I left it optional in case there was some
platform that still needed to manually install the wasm variant with
`npm install --cpu=wasm32 sharp` such as codesandbox/stackblitz (I don't
believe sharp has any fallback built in yet).
Since we can guarantee `sharp`, we can also remove `get-orientation` dep
and upgrade `image-size` dep.
I also moved an [existing `sharp`
test](https://github.com/vercel/next.js/pull/56674) into its own fixture
since it was unrelated to image optimization.
