Adds an err.sh link to the production build missing message. Also clears up `valid` as `production`.
Also fixes an edge case where an unhelpful error would be thrown because we checked for `.next` instead of `.next/BUILD_ID`
Added the out directory location as the list line during export to make sure people know where the files are output.

Removes `next-head-count`, improving support for 3rd party libraries that insert or append new elements to `<head>`.
---
This is more or less what a solution with a `data-` attribute would look like, except that instead of directly searching for elements with that attribute, we serialize the elements expected in `<head>` and then find them/assume ownership of them during initialization (in a manner similar to React's reconciliation) based on their properties.
There are two main assumptions here:
1. Content is served with compression, so duplicate serialization of e.g. inline script or style tags doesn't have a meaningful impact. Storing a hash would be a potential optimization.
2. 3rd party libraries primarily only insert new, unique elements to head. Libraries trying to actively manage elements that overlap with those that Next.js claims ownership of will still be unsupported.
The reason for this roundabout approach is that I'd really like to avoid `data-` if possible, for maximum compatibility. Implicitly adding an attribute could be a breaking change for some class of tools or crawlers and makes it otherwise impossible to insert raw HTML into `<head>`. Adding an unexpected attribute is why the original `class="next-head"` approach was problematic in the first place!
That said, while I don't expect this to be more problematic than `next-head-count` (anything that would break in this new model also should have broken in the old model), if that does end up being the case, it might make sense to just bite the bullet.

Warn users and revert their `devtool` when they manually change the `devtool` in development mode. For this addition, I check to ensure the `devtool` is custom (i.e. different than what is set by Next) and has a value (`false` is fine as a custom `devtool`!).
As described in [this issue (13963)](https://github.com/vercel/next.js/issues/13963), changing the `devtool` in development mode can cause issues with performance.
Fixes#13963
**First, apologies for a second PR on the same issue but I was working on this already so I thought I'd push it and let you decide which you want to merge.**
The PR is related to [13466](https://github.com/vercel/next.js/issues/13466).
Based on my research, the error happens if the options are empty, null, or undefined. That's why I have decided that the most proper check would be using the! post-fix expression operator may assert that its operand is non-null and non-undefined. ``if (options == null)``
(Optional)
I have also added a warning, which warns the user if the passed "dev" variable is not a boolean.
It's my first PR on the "packages" part of the repo so I'd be glad to receive all kinds of critics. If you want me to change or remove anything, I'm open to suggestions.

When overriding `config.resolve.alias` incorrectly webpack will throw an error because private-next-pages is not defined. This adds a more descriptive error explaining the error better.
Fixes: #6681
### changes
#### remove trailing spaces
When I was using example I noticed trailing spaces.
So, this PR removes the trailing spaces of json file, README, and others.
`examples/with-jest-typescript/src/modules/cars/Overview.tsx` also has it, but this time it did not change as tslint error occurs at commit.
* Update to use the correct router instance in withRouter so error is
thrown when router method is used during SSR
* Revert changes to with-router and add error to methods on
direct router instance
* Extend Router and override methods with error instead
* Update ServerRouter, add err.sh, and add test
* Add warning on stalled page load possibly from too many tabs open
* Add test for stalled warning
* Update onDemand pinging to close on routeChangeStart and added
warning when onDemand handler detects multiple tabs from the same
browser
* Show error when `router` or `Component` are returned in _app.js
getInitialProps
* Update to only show error in dev mode
* Update packages/next-server/server/render.tsx

After talking with @timneutkens it was decided it'd be more streamlined to replace the onDemandEntries WebSocket with an alternative. Using the EventSource connection gives us these benefits over the WebSocket one:
- less code needed
- no extra server running
- no extra config for onDemandEntries
After discussion, I added falling back to fetch based pinging when the WebSocket fails to connect. I also added an example of how to proxy the onDemandEntries WebSocket when using a custom server. Fixes: #6296
Closes: #6244
This will block the following keys:
```
NODE_.+
__.+
```
There doesn't seem to be a way to simulate a failed build or else I'd add tests for it.
* Implement circular JSON err.sh link
* Add test for getInitialProps returning circular json
* Make test warn less
* Fix tests
* Add reference to original tests
# Fixes https://github.com/zeit/next.js/issues/5674
This adds config option
```js
// next.config.js
module.exports = {
crossOrigin: 'anonymous'
}
```
This config option is defined in the webpack Define Plugin at build.
`Head` and `NextScript` now use the config option, if it's not explicitly set on the element.
This value is now passed to Webpack so it can add it to scripts that it loads.
The value is now used in `PageLoader` (on the client) so it can add it to the scripts and links that it loads.
Using `<Head crossOrigin>` or `<NextScript crossOrigin>` is now deprecated.
* show warning if there is a title in _document.js Head
* dont loop through children in production
* only 1 loop through this.props.children 💪
* also raise warning in test env
* check for null childs
* Throw error if getInitialProps is defined as as instance method
Omitting the static keyword happens pretty often. Therefore we should trigger a warning in devmode.
Closes: #4782
* Document getInitialProps error
* Add unit tests for loadGetInitialProps
* Expose pages/_app.js
* Add tests for _app and _document
* Uncomment deprecation warnings
* Add documentation for _app, improve documentation of _document
* Update docs / test for _document
* Add _document to client compiler in development
* Add missing app.js to comment
* Only warn once
* Add url-deprecated error page
* Combine tests
* Yse same message for all methods of ‘props.url’
* Update docs around _app
* Update documentation
* Quotes
* Update table of contents
* Remove special error script handling.
As a result of that, we can't detect 500 errors and buildIdMismatch via client side.
* Fix failing test cases.
* Refactor the code base.
* Remove Router.onAppUpdated
This reverts `fb7c862` per @timneutkens
- Removes the errors/*.md associated
- Puts back `poweredByHeader` for `next.config.js`
- Reincorporates test:
X-Powered-By header
✓ should set it by default (3ms)
✓ should not set it when poweredByHeader==false (5ms)
Also tested with `yarn link` and verified.
