## 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.
This PR updates the minimum version of React used by examples from 17.0.2 to 18.2.0.

Found that this rule was added but all options are set to `false` so it doesn't do anything. Started with enabling it for examples to ensure minimal breaking of existing PRs.

~⚠️ I lazily created this PR from Github directly as I don't have a local build of next.js on my current machine.
If ever linting does not pass, I will update this later today (sorry for the noise).
EDIT: it does not, I will update this PR shortly.~
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)
}
```
## Description
This year we implemented the new Apollo config using this example. We recently moved to `getServerSideProps` as well, however, this was giving us some cache problems. The issue was that the cache was older than the actual data that was coming from the server side query.
Because the `merge` of the cache in `apolloClient.js` is merging the existingCache in the initialState it will overwrite the "fresh" initialState with properties that already exists. This means that if you have something in your cache from previous client render, for example `user` with the value `null`, and you go to a new page and do a new query on the server which returns a value for the `user` field, it will still return `null` because of that `merge` function.
Since this was weird in our opinion, we've changed this in our own environment by always overwriting the existing cache with the new initialState, so that the initialState that is coming from a fresh server side query is overwriting. We thought it was a good idea to reflect this also in this example, because we couldn't think of a reason why the existing cache should overwrite fresh queries.
I've added a reproduction that shows what this is exactly about. I hope my description makes sense, let me know what you think!
## Reproduction of old scenario
Created a reproduction branch here: https://github.com/glenngijsberts/with-apollo-example. Using a different API than in the example, because of https://github.com/vercel/next.js/issues/32731.
1. checkout the example
2. yarn
3. yarn dev
4. visit http://localhost:3000/client-only
5. Hit "Update name". This will run a mutation that will update the cache automatically. Because I use a mocked API, the actual value on the API won't be updated, but this is actually the perfect scenario for the problem because in reality data can already change in the meantime when you're doing a new request.
6. Go to the SSR page
7. This will display two values: one is coming from the server side request (which is the latest data, because no cache is used in `getServerSideProps`) and the other is using the cache, which is outdated at that point, yet it's still returned because the old way of merging the cache was picking the existing cache over the initialState that was coming from the fresh server side query.

* Add licences to all example/package.json that lack them
* Revert "Add licences to all example/package.json that lack them"
This reverts commit 5d4e25012f7334772b8ef5924bc355277e827cba.
* 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
```
The intention is to show people the correlation between things, in this case, understand the usage of the same key from the props and the rehydration.
Hopefully, this change will bring value as it has done with some Juniors already.
**What's the problem this PR addresses?**
A decent amount of the examples don't have a `name` field in `package.json` that matches their folder name, meaning they either lack a name or the names are duplicated.
I was testing Yarn 2 workspaces using the entire examples directory and needed to get rid of the duplicates.
**How did you fix it?**
Updated the names to match the names of their folders
## Motivation
As Graphcool is being shutdown, we replaced all the graphcool api endpoints with some handcrafted APIs using Prisma & Nexus, that can be found here https://github.com/prisma-labs/nextjs-graphql-api-examples. These GraphQL endpoints are now deployed to Vercel.
## Notes
- I couldn't get the reason-relay example to run. Given that the relay endpoint works on the other relay example, I don't see any reason why it wouldn't work on that one
- The `with-apollo` example is buggy when creating some posts, but nothing related to the switch of the api endpoint as it was already buggy before. I suspect the `concatPagination` strategy to be the cause of that bug, but I couldn't figure it out.
Fixes#14780
Based on https://github.com/vercel/next.js/pull/13607 - I created a new PR as I can't push changes to the initial PR.
Migrated the Apollo client to use SSG, also removed the link to the live demo because I don't know who the owner is or how to update the deployment.
The implementation is pretty simple and will be added to all the other Apollo examples
The props are being assigned incorrectly based on the `inAppContext`, they should be wrapped in `pageProps` when `inAppContext` is true, not the other way around. This will cause a new apollo client to be created during `getDataFromTree` instead of using the one that has already been created on the server.
