Because there is a TS error when is set just a string:
`TS2322: Type '() => string' is not assignable to type '(loadingProps: DynamicOptionsLoadingProps) => Element | null'. Type 'string' is not assignable to type 'Element'.`
## Background
In the early days, `next export` was created when Next.js was SSR-only in order to statically export your pages for self hosting where no server was available. However, around the time `getStaticProps()` and `getStaticPaths()` were introduced, Next.js began [automatically generating static pages](https://nextjs.org/docs/advanced-features/automatic-static-optimization) (SSG first and SSR opt-in) during `next build`. This meant there were very few reasons to use `next export` and it started to become a stale feature.
## Problem We Need To Solve
Users targeting `next export` currently have a really bad experience. They start a new project and use all the features Next.js has to offer because they all features work with `next dev`. Then when development is finished and it comes time to deploy, running `next build && next export` will fail with errors for [unsupported features](https://nextjs.org/docs/advanced-features/static-html-export#unsupported-features).
## Solution
This PR introduces a new configuration option, `output: 'export'`, to indicate that the user intends to run `next export`.
With this change, Next.js can fail fast during `next dev` if any [unsupported features](https://nextjs.org/docs/advanced-features/static-html-export#unsupported-features) are used, thereby improving developer experience with instant feedback.
```js
/**
* @type {import('next').NextConfig}
*/
const nextConfig = {
output: 'export',
}
module.exports = nextConfig
```

# Description
fixes#31159fixes#44553
Path aliases defined in `tsconfig.json` or `jsconfig.json` are not
automatically configured to work with Jest. This means that these
aliases have to be defined in multiple places.
This PR configures the SWC Jest transform to handle the `baseUrl` and
`paths`, so that users don't need to configure a `moduleNameMapper` for
Jest.
~This PR intends to make the experience more seamless by automatically
configuring Jest's `moduleNameMapper` and `moduleDirectories` based on
the settings in a project's `tsconfig`/`jsconfig`.~
~Users will be able to supply their own configuration for these fields,
if they have use-cases that require manual configuration.~
~The implementation is taken from the [`paths-to-module-name-mapper`
function in
`ts-jest`](5a0880add0/src/config/paths-to-module-name-mapper.ts).~

Add `contentDispositionType` config to Image Optimization API so the user can configure `inline` vs `attachment`.
This is recommended when `dangerouslyAllowSVG` is enabled but can also be used when its disabled.

This adds a top-level experimental config for including/excluding files
from the file traces. This replaces the page level
`unstable_includeFiles`/`unstable_excludeFiles` as those had some
drawbacks such as not being supported for API routes as these files
aren't required during build to gather the configs, having to duplicate
includes/excludes for multiple pages, and causing more confusion for
where the globs were meant to be relative to.
The new top-level configs allow mapping page globs to includes/excludes
so they can be shared across multiple pages or a single page. These can
also affect the `next-server` trace by specifying that as the key if
necessary. The previous `outputFileTraceIgnores` config is automatically
mapped to the new config with a deprecation warning.

Turbotrace occupies too many memories while running; this PR makes it
run after the webpack build is finished, it can reduce the memory
hogging by webpack and turbotrace, thus avoiding OOM
The `maxFiles` option in turbotrace is removed because there is
`memoryLimit` option takes over its role.
Close WEB-556
This adds:
- Documentation for Turbopack experimental fields `turbopackLoaders` and `resolveAlias` to the API reference site.
- Typings and schema for the above Turbopack experimental options
Test Plan:
- `pnpm build`, updated an example to use TypeScript for its Next.js config, and verified the config passed with matching shapes and failed with mismatching shapes.
[Cypress](https://www.cypress.io/) recently went GA with a Component Testing offering which supports Next.js. This PR adds a brief section on what and how to use Cypress for component-level testing and updates the example project with a component test.
Any feedback on content or the example is welcome, thanks for considering!

In some apps like `vercel/site`; tracing the entries is unnecessary but
is really time/memory consuming. In this case, we should expose an
option to disable tracing the entries.
