The following error occurred
when I created a project with the typecript template of createp-next-app
and did the 'next build'.
```shell
It looks like you're trying to use TypeScript but do not have the required package(s) installed.
Please install @types/node by running:
yarn add --dev @types/node
If you are not trying to use TypeScript, please remove the tsconfig.json file from your package root (and any TypeScript files in your pages directory).
```
This issue was resolved by adding @types/node.
So I added @types/node to the devDependencies of the create-next-app typecript template.
Current docs on exposing environment variables to the browser are slightly misleading as they say that variables loaded from `.env.local` are only available in node by default, but this is the case for all environment variables not just those loaded from `.env.local`.

This type was added in PR #28269 but doesn't need to be public and was causing conflicts with `@types/react@17`.
We currently use `@types/react@16` so ideally we should upgrade to `@types/react@17` and then remove the `ts-ignore`.
Fixes#28647

Previous to this change, getServerSideProps could only return plain objects
for props, e.g.:
```javascript
export async function getServerSideProps() {
return {
props: {
text: 'some value',
}
}
}
```
With this commit, the props object can also be a Promise, e.g.
```javascript
export async function getServerSideProps() {
return {
props: (async function () {
return {
text: 'promise value',
}
})(),
}
}
```
For now, the framework simply waits for the results of the props Promise to resolve,
but this small change sets the groundwork for later allowing props to be streamed (cc @devknoll).

The client now warns against missing `apiVersion` ([docs](https://www.sanity.io/docs/api-versioning)). This PR adds the config for using the latest API version. There shouldn't be breaking changes in this app.

This PR updates the with-jest example to the latest version of Jest and adds a note about the Jest and RTL testing environments (related to this [discussion](https://github.com/vercel/next.js/discussions/28337)). Also adds minor tweaks to the testing docs.

* Use recommended pattern in testing example
Since the official linter for testing library, `eslint-plugin-testing-library` recommends using `screen` to write queries, this MR updates the testing library example to follow the pattern recommended by the linter.
> DOM Testing Library (and other Testing Library frameworks built on top of it) exports a screen object which has every query (and a debug method). This works better with autocomplete and makes each test a little simpler to write and maintain.
> This rule aims to force writing tests using built-in queries directly from screen object rather than destructuring them from render result. Given the screen component does not expose utility methods such as rerender() or the container property, it is correct to use the render returned value in those scenarios.
See the `prefer-screen-queries` rules docs for more info: https://github.com/testing-library/eslint-plugin-testing-library/blob/main/docs/rules/prefer-screen-queries.md
* Update devDependencies
* Install and configure test linting
* Use recommended pattern in test
* Update test names for consistency
* Update docs
* Set jest environment in each file
* Use root true in `with-jest` eslint config
* Ensure nested .eslintrcs are not loaded for repo lint

Just a small change to recently merged PR; for some reason `import couchbase from 'couchbase'` is not working correctly when I use create-next-app to bootstrap with the `with-couchbase` example, despite initially working within my local next.js directory. The wildcard import fixes that issue. Thanks!

This adds a simple `with-couchbase` example app complete with a check for successful connection (in `index.js`).
**Note:** To check the connection, this application runs a simple KV GET operation with a key that does not exist and expects a response of `document not found`. Any other response indicates a failure to connect.
Thank you!
This updates our `jest` configuration to no longer use `babel-jest` and instead uses `@swc/jest` which is much faster. This also updates to the latest version of `jest`, fixes our `tsconfig.json` used for tests (previously types in `node_modules` weren't resolved correctly), and ensures `next/dist` isn't un-necessarily transpiled in `jest`.
