## Background
Currently route handlers will be attempted to statically generate the
same as normal pages in app router. If a route handler accessed dynamic
data such as `cookies()`, `headers()`, `req.url`, or similar we would
bail from this static generation but this didn't handle the case where
you would do data fetching via a non-fetch based library e.g. `redis` or
even using `Date.now()` or `Math.random()` so users would expect these
to be run every request like normal API endpoints but they would be
static so wouldn't be executed again after a build.
## New Behavior
As discussed this disable the default static generation handling for
route handlers as we've seen this confuse our users since in most cases
when creating a route handler you are handling dynamic workloads. This
doesn't remove the ability to static generate route handlers though as
you can still manually specify:
If you specify `export const revalidate = 1` we will still bail if
dynamic data is accessed to prevent accidental `revalidate` configuring
but this can be avoided via `force-static` being used as well.
```js
export const dynamic = 'force-static'
// or
export const dynamic = 'error'
// or
export const revalidate = false
// or
export const revalidate = 1 // value great than 0
// or
export const generateStaticParams() {}
```

## What?
This test currently causes others to fail. Trying adding a skip for this
to see if other issues come up before porting it to be isolated:
```
● Test suite failed to run\n\n The name `source-map` was looked up in the Haste module map. It cannot be resolved, because there exists several different files, or packages, that provide a module for that particular name and platform. The platform is generic (no extension). You must delete or exclude files until there remains only one of these:\n\n * `/root/actions-runner/_work/next.js/next.js/packages/next/src/compiled/source-map/package.json` (package)\n * `/root/actions-runner/_work/next.js/next.js/test/integration/app-dir-export/output/standalone/packages/next/dist/compiled/source-map/package.json` (package)\n\n at ModuleMap._assertNoDuplicates (../node_modules/.pnpm/jest-haste-map@29.7.0/node_modules/jest-haste-map/build/ModuleMap.js:189:11)\n

Closes NEXT-2955
### What
Supports partial `get-page-static-info` in turbopack. Since turbopack
doesn't have equivalent place to webpack's ondemandhandler, it uses
turbopack's build time transform rule instead.
As noted, this is partial implementation to pagestatic info as it does
not have existing js side evaluations. Assertions will be added
gradually to ensure regressions, for now having 1 assertion for
getstaticparams.
Closes PACK-2849
## 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.

Closes NEXT-2915
## 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`

This ensures we don't normalize the `distDir` in the webpack config in
dev mode as it won't be moved to the right location like it is during
build.
Fixes: https://github.com/vercel/next.js/issues/61105
Closes NEXT-2495
formalizes the concept of dynamic APIs inside Next to allow for varying
semantics beyond just staticGenerationBailout.
### Dynamic APIs
#### `markCurrentScopeAsDynamic`
useful to bail out of default caching semantics but does not imply a
Request specific data source was read. critically, this semantic is
ignored if you are inside a cache scope
#### `trackDynamicDataAccessed`
Must be called before reading any data source that is derived from
Request specific data. Currently this is `cookies()`, `headers()`, and
`searchParams`. This kind of data access inside a cache scope is
forbidden (it always should have been, but now it will error).
#### `trackDynamicFetch`
This one is unideal but the complexity of patch-fetch's current
implementation necessitates it for now. Essentially it will postpone if
we are prerendering. Long term this should be eliminated with a refactor
of patch fetch.
### Other Improvements
Also removes the `staticGenerationBailout` implementation as it has been
replaced with more specific logic in the places it was previously being
used.
One area that has also been enhanced is the proxy for app-route modules.
Previously we proxied the Request every time however when we are doing
non-static generation executions we generally don't want the overhead of
wrapping the request. In the refactor here I also improved the runtime
performance by using static proxy handlers and I believe I also fixed a
few bugs related to `clone` and `url`
In general there has been a bit of refactoring to clarify how we should
handle various render/execution states and a reduction in implicit side
effects for proper execution.
Another callout to notice is that app-route modules do not attempt a
static generation if they are force-dynamic regardless of the PPR
setting. Previously the PPR setting would opt them into this code path
which is not necessary because PPR itself does not work for routes, only
pages.
Closes NEXT-2099
Fixes#57038
# What?
Added an error message when `generateStaticParams` returns an empty
array with `output:export`.
# Why?
To provide developers with clear feedback when `generateStaticParams` is
not used correctly.
# How?
Modified the condition checks around the use of `generateStaticParams`
to include a check for an empty array and added a corresponding error
message.

BREAKING CHANGE
Since `next export` has been printing a deprecation warning since https://github.com/vercel/next.js/pull/47376, its safe to remove in semver-major.
The upgrade path is to simply add `output: 'export'` in `next.config.js` - everything will continue to work the same.
This config greatly improves the `next dev` experience today. And in the future, it will improve performance of `next build` because we no longer need to do two passes (build then export).
Skips additional production-only tests.
Follow-up to #56089.
In this PR I went through all of `test/integration` looking for `nextBuild(` and added the skipping logic.
### What?
This PR enables basic support for next.config.js's `distDir` config. PR have two main pieces, one for honoring distDir and construct output path other than `.next`, and secondly assign `process.env.__NEXT_DIST_DIR` to client / edge. The latter increased size of PR bit as had to downstream to the compile_define calls.
Corresponding tests are enabled to verify its behavior.
Closes WEB-1610
We already have a warning when using `next export` with `output: export` because the `next export` is effectively a no-op (the exported output was already generated during `next build`).
However, this PR ensures that `next export -o <dir>` throws an error when `output: export` is defined because the files were already emitted to the `distDir` in the `next build` step and we can't safely no-op at this point.
We also guide the user to the correct solution which is to use `output: export` along with `distDir: <dir>` in your next.config.js (instead of mixing legacy behavior with the new behavior).
fix#48207
fix NEXT-980
## What?
Removes `experimental.appDir` this was leftover from when I flipped the
switch.
Kept the config file as in the future we might add future flags and
such. It also helps that it has the types comment included so you always
get types.

fix NEXT-885 ([link](https://linear.app/vercel/issue/NEXT-885))
This PR ensures the correct output is emitted during `next build` and
deprecates `next export`.
The `output: export` configuration tells it to emit exported html and
the `distDir: out` configures the output directory.

module.exports = {
output: 'export',
distDir: 'out',

The `exportPathMap` feature has been unofficially deprecated for a long time since introducing `getStaticPaths()`.
For the `app` dir, the same can be accomplished with `generateStaticParams()`.
This PR adds a pretty error when using `exportPathMap` with `app` and updates documentation to reflect the current status.
fix NEXT-836 ([link](https://linear.app/vercel/issue/NEXT-836))
In the case when the user configured `output: export` and used an API Route Handler that cannot be converted to static, Next.js must throw an error.
fix NEXT-823 ([link](https://linear.app/vercel/issue/NEXT-823))
Previously when we move to metadata images to custom app routes, when the image files get imported, it matches the `next-image-loader` rule which accidentally generate a static file into media.
This PR appends the metadata reource query to the imported rerource, and then skip in the `next-metadata-route-loader` so they won't get applied by image loader or emit any unexpected assets
