Implement dynamic redirect (#624)

[fnlctrl]

With e2e tests

[fnlctrl]

Should we cache type of redirect === 'function'?
I didn't because I thought it was too trivial.

It doesn't have an impact on performance so I think it's ok this way.

However, I think it's better to call redirect if it's a function and let the rest of the code the same:

redirect = typeof redirect === 'function' ? redirect() : redirect

This way the return of redirect can also be an object with a name and it's more flexible

[fnlctrl]

Yep! You're right, fixing it now

Shouldn't the redirect function have access to the target route to be actually useful?

[fnlctrl]

@yyx990803 Sure it would be useful, but the target route is match()-ed after consuming the redirect option... and this context is not available here, so I don't know what can be passed to the redirect function...

[yyx990803]

we can pass createRoute(record, location)

[fnlctrl]

Yeah, that makes sense! On it now.

[yyx990803]

Ideally also need a test case for the to argument ;)

[fnlctrl]

Right.. I'll get back to it after dinner 😄

Failed to load resource: the server responded with a status of 404 (Not Found)

Strange that I can't seem to run e2e tests on the current PC I'm using (was running fine on another one), npm run dev has the same error too...
Tried npm cache clear npm install many times still no luck..

Using CI for debug now.. sigh

[fnlctrl]

Note:
Stuck on removing hash and query after redirect

[posva]

Apart from tests failing LGTM

Merging as-is and fixing it later
