* Add amp request header and check for amp
query in serverless mode

* Add serverless test for an AMP page

* Update to handle querystring weirdness

* Update serverless test config

I got stuck for a while on not being able to set up a global method due to process.envs not being able to be destructured. Hope to allow others not to spend as much time on it as I did!

- fix runtime configuration example to use `customKey`
- standardize warning callouts to use a block quote and bold "**Warning:**" text. Previously there were different ways a warning was mentioned on the docs page:
  - A warning emoji. The warning emoji didn't render in the actual site.

  - Italicized "Warning" text. Imo, does not stand out on the page.

* Adde example on how to rendering muiltiple items carousel on server-side with nextjs

Hi everyone :)
I just updated Sentry to v5 and added @sentry/integrations due to breaking changes :)
I also fix the documentation. npm commands were in yarn section.

This merge request updates `fastify` package from v1 to v2 and adds the `cross-env` package so `NODE_ENV=` can work on Windows as well as OSX/Linux. Also adds example build output to GITIGNORE

Worth mentioning that pressing `a` will bring up a page that says `b` and vice-versa, but this seems to be the logic from the previous example as well. Can change if wanted

As requested in this issue: https://github.com/zeit/next.js/issues/6850

This is a basic HTTP2 server which can handle the `/` and `/about` routes. 

The Readme includes [specific instruction](https://github.com/shahzeb1/next.js/blob/31877720f076b49b39a167deb0ba8650d0052dda/examples/with-http2/README.md#download-manually) about how to generate the public/private keys used for this demo server.

This introduces the `useRouter` hook alternative to `withRouter`

* Update the `ad` comment

* Avoid all buildId's that contain "ad"

Looking through the uBlock Origin filter list, it uses regex wildcards to avoid various things with "ad" anywhere in the string. It's a safe bet to just avoid "ad" all together (as opposed to just at the start).

* Use regex (case incensitive) to check for "ad" 

The following cases will set this regex to true:

```
/ad/i.test("somead")
/ad/i.test("someADlksdjf")
/ad/i.test("adlksdjf")
/ad/i.test("ADlksdjf")
```

* Added a check for ad_ in the buildId

* ad_ > ad
