Because Typescript output is turned to commonjs for these modules currently it’s better to do this. Also convert withRouter to typescript, making it smaller.
By default when `next export`ing a Next.js application we will automatically append a `/` to all urls to be fully compatible with the directory structure being output.
However since most platforms support directory indexes it makes sense to change this default in the future.
This PR adds `exportTrailingSlash` as experimental flag. We'll try this out for a bit on nextjs.org / zeit.co/docs before introducing it as new option.
The default value is `true` as this is the current behavior in stable Next.js.
```
{
experimental: {
exportTrailingSlash: false
}
}
```
⚠️ as with all experimental flags being added this is subject to breaking between canary/stable versions.
- Removed `fetchRoute` as it was only used once (internal method, non-breaking)
- Convert files to TypeScript
- Don't extend `ServerRouter` from `Router` as it introduces unneeded overhead, we only have to provide `pathname` `asPath` and `query` for `withRouter`. Also added `events` even though it shouldn't be called on SSR, just making sure we don't break things.
* Apply workaround for Firefox bug
and shallow routing
* Update to only apply workaround when needed
* Add TODO for future removal

* make router UrlIsNew comparing method work as expected
* Remove shallow-equals from router and update urlIsNew check
* Remove shallow-equals test since it is no longer used
* Add integration test for asPath query
original code in `/lib/router/router.js`
```
urlIsNew (pathname, query) {
return this.pathname !== pathname || !shallowEquals(query, this.query)
}
```
the urlIsNew compare `this.pathname` to an argument `pathname`
the invokers:
```
// If asked to change the current URL we should reload the current page
// (not location.reload() but reload getInitialProps and other Next.js stuffs)
// We also need to set the method = replaceState always
// as this should not go into the history (That's how browsers work)
if (!this.urlIsNew(asPathname, asQuery)) {
method = 'replaceState'
}
```
the parameter here is `asPathname` destructured from `asPath`
so here is a problem when we reuse a single page rendered in two asPaths
pages/a.js
```
<>
<Link href='/a'><a>goto a</a></Link>
<Link href='/a' as='/b'><a>goto b</a></Link>
</>
```
If we navigate to page /a, then click 'goto b', actually the history is replaced, not pushed.
It is expected that history could be correctly pushed and popped as long as the browser url is changed.
This PR aims at replacing next-server/lib/event-emitter.js by mitt.
Fix https://github.com/zeit/next.js/issues/4908
event-emitter.js is ~400 bytes gzipped vs mitt is 200 bytes
Resolves#4055

I didn't use the ignore webpack plugin from the original PR and tested bundle size with https://github.com/zeit/next.js/pull/5339 - seems to be safe on that front.
Was able to get tests to pass locally, unsure of what goes wrong in CI 🤷♂️
**Questions**
1) The initial PR didn't include changes to `next-server/lib/router` in `getRouteInfo()`. Should the same changes be made within?
2) Should we add a test for rendering a component created via `forwardRef()`?
`component-with-forwardedRef`:
```javascript
export default React.forwardRef((props, ref) => <span {...props} forwardedRef={ref}>This is a component with a forwarded ref</span>);
```
some test:
```javascript
test('renders from forwardRef', async () => {
const $ = await get$('/component-with-forwardedRef')
const span = $('span')
expect(span.text()).toMatch(/This is a component with a forwarded ref/)
})
```
- Replaces taskr-babel with taskr-typescript for the `next` package
- Makes sure Node 8+ is used, no unneeded transpilation
- Compile Next.js client side files through babel the same way pages are
- Compile Next.js client side files to esmodules, not commonjs, so that tree shaking works.
- Move error-debug.js out of next-server as it's only used/require in development
- Drop ansi-html as dependency from next-server
- Make next/link esmodule (for tree-shaking)
- Make next/router esmodule (for tree-shaking)
- add typescript compilation to next-server
- Remove last remains of Flow
- Move hoist-non-react-statics to next, out of next-server
- Move htmlescape to next, out of next-server
- Remove runtime-corejs2 from next-server
