## Summary
Updates the `with-mysql` example to use latest versions of all
dependencies.
### What
- Migrate from Pages Router to App Router
- Update to React 19 and Next.js latest
- Update to Tailwind CSS v4 with `@import "tailwindcss"` syntax
- Update to Prisma 7 with `@prisma/adapter-planetscale` driver adapter
- Convert all files to TypeScript
- Remove unused API route and `vercel.svg`
- Update README to clarify this is for PlanetScale MySQL and link to
[vercel/postgres-next-starter](https://github.com/vercel/postgres-next-starter)
for Postgres users
### Why
The example was significantly outdated:
- Prisma 3.10.0 → Prisma 7 (latest)
- Tailwind 3.0.23 → Tailwind 4
- React 18.2.0 → React 19
- Pages Router → App Router
### How
Followed the official migration guides:
- [Prisma 7 upgrade
guide](https://www.prisma.io/docs/orm/more/upgrade-guides/upgrading-versions/upgrading-to-prisma-7)
- [PlanetScale quickstart with
Prisma](https://www.prisma.io/docs/getting-started/prisma-orm/quickstart/planetscale)
- Aligned configuration files with a fresh `create-next-app` output

## What?
Update examples `.gitignore` files for parity with [Yarn's official
recommendations](https://v3.yarnpkg.com/getting-started/qa#which-files-should-be-gitignored),
accounting for Yarn's modern Plug-n-Play functionality.
## Why?
New projects initialized with `create-next-app` presently add various
extraneous files from the Yarn cache to the initial commit. This is most
notable in the case of the Next SWC binary, which may exceed 100M in
some environments (empirically, 64-bit Darwin and WSL2 Ubuntu, and very
probably other unix/linux environments), and prevent users from pushing
their new projects to free GitHub repositories without rewriting the
commit history to exclude the extraneous files, or unnecessarily setting
up Git LFS to include them.
## How?
I have errored on the side of exclusion to enable users to push their
CNA projects to GitHub as-is and for parity with other package managers,
while still providing the opportunity to opt in to additional
functionality provided by modern Yarn.
These changes follow the recommendations for
**non**-[Zero-Install](https://yarnpkg.com/features/caching#zero-installs)
configurations, as Zero-Install functionality is an extension on top of
the base package manager experience, and may necessitate additional
configuration and present additional complications for unsuspecting
users, so I think it's best left up to the user to opt-in. On account of
the majority of publicly available Next.js-based projects comprising
general consumer-facing websites, it is my belief that the majority of
Next projects would not benefit from Yarn's Zero-Install functionality,
and that explicitly facilitating it by default would break status quo
with all other non-Yarn CNA projects.
Contrary to the example `.gitignore`s provided by Yarn, I've excluded
the `.yarn/sdks` directory as it contains IDE-specific tooling; I feel
it would be presumptuous for an environmentally-agnostic tool to target
and provide package-manager-specific tooling for specific editors. This
too should be left to the user to opt-in to and provide for their
project if they deem necessary.
I have retained the current `.gitignore`'s exclusion of the `/.pnp`
directory for backwards compatibility with older versions of Yarn (the
files therein have since been reallocated to the `.yarn` directory
addressed by these changes, but I am not clear on when that delineation
occurred or the prevalence of Yarn installations which depend on the
former convention). Maintaining the exclusion here, in the worst case,
implies additional downloads (on an order of magnitude merely similar to
using npm from the outset) rather than failure.

## 📚 Fixed some typos
Hello, while reviewing the source code in `examples` directory, I found
some unnecessary blank spaces. So I fixed them.

## Description
This PR ensures that the default prettier config is used for examples
and templates.
This config is compatible with `prettier@3` as well (upgrading prettier
is bigger change that can be a future PR).
## Changes
- Updated `.prettierrc.json` in root with `"trailingComma": "es5"` (will
be needed upgrading to prettier@3)
- Added `examples/.prettierrc.json` with default config (this will
change every example)
- Added `packages/create-next-app/templates/.prettierrc.json` with
default config (this will change every template)
## Related
- Fixes#54402
- Closes#54409
### Reason for making this change
https://yarnpkg.com/getting-started/qa#:~:text=yarn%2Finstall%2Dstate.,your%20workspaces%20all%20over%20again.
In the official documentation of `yarn`, it is stated that `.yarn/install-state.gz` is an optimization file that developer shouldn't ever have to commit. However, currently, when running `create-next-app`, `.yarn/install-state.gz` is being commited.
### Remaining work
I apologize for only modifying one template initially to initiate the discussion first.
If this change is agreed upon, it should be synchronized with other `.gitignore` templates. Would it be possible to follow a similar approach as in https://github.com/vercel/next.js/pull/47241? I would appreciate any assistance in syncing this change.
Next.js 13 will require React 18.
In this PR I've only updated the peerDependency and removed the test runs in GH actions. Further cleanup will follow later, this allows us to remove the code supporting it later.

## Summary
- Added jsdoc typing for all examples using `next.config.js`
- Added jsdoc typing for all examples using `tailwind.config.js`
## Documentation / Examples
- [x] Make sure the linting passes by running `pnpm lint`
- [x] The examples guidelines are followed from [our contributing doc](https://github.com/vercel/next.js/blob/canary/contributing.md#adding-examples)
This PR updates the docs and examples for `create-next-app` to include pnpm usage.
The following script was used to update every example README:
```js
const fs = require('fs')
const examples = fs.readdirSync('./examples')
for (let example of examples) {
const filename = `./examples/${example}/README.md`
const markdown = fs.readFileSync(filename, 'utf8')
const regex = new RegExp(`^yarn create next-app --example (.*)$`, 'gm')
const output = markdown.replace(regex, (yarn, group) => {
const pnpm = `pnpm create next-app -- --example ${group}`
return `${yarn}\n# or\n${pnpm}`
})
fs.writeFileSync(filename, output)
}
```
Changes from https://github.com/planetscale/nextjs-starter.
Realized the current example was not only out of date, but the demo was broken. Will update the demo site post-merge here 👍
Old PR: #32197
I forgot I had that PR open and I removed my fork. So, I've reopened this PR to solve the merging conflicts

* Add licences to all example/package.json that lack them
* Revert "Add licences to all example/package.json that lack them"
This reverts commit 5d4e25012f.
* Update check-examples to remove `license` field from examples
* Remove `license` from all examples.
This was mentioned in vercel/next.js#27121 but it looks like it didn't end up being in the merge?

Clean up package.json files in the `examples` directory:
- Add `private: true`
- Remove `version` (because they are irrelevant for packages that are not meant to be published)
- Remove `name` (because they are optional for packages that are not meant to be published, and when someone clones an example, they often rename it and the property becomes stale)
- Remove `author`
- Remove `description`
- Remove `license`
Also remove `with-dynamic-app-layout` example completely, since it does the same as `layout-component` (https://github.com/vercel/next.js/pull/27121#discussion_r668178408).
## Documentation / Examples
- [x] Make sure the linting passes
[With next 11 requiring react 17](https://nextjs.org/blog/next-11#upgrade-guide), most of the examples
need to be updated, so the following snippet updated all the examples to
a compatible react version.
```bash
cd examples/
fd -g 'package.json' | xargs sed -r -i 's/"react": ".*"/"react": "^17.0.2"/
fd -g 'package.json' | xargs sed -r -i 's/"react-dom": ".*"/"react-dom": "^17.0.2"/'
# exclude experimental react version
git checkout with-reason-relay/package.json
```
Added port config variable to the migrate-db.js script and .env.local.example files. This allows users to set the port for remote databases like Digital Ocean that don't use the default port.
