Add "types" to path matchers.

[mthadley]

Hey everyone, I wanted to throw out a quick idea that may reduce some of the boilerplate when defining our routes.

It's pretty common to define a route like this, possibly many times, that is meant to match some kind of number:

<Route
  component={userPage}
  path="user/:id(\d+)/"
/>

After a while, it get's tedious to add these regexes to our routes, and also reduces readability. Maybe instead we could still allow for a regex, but also provide some default "types":

<Route
  component={userPage}
  path="user/:id<number>/"
/>

The syntax is subject to change, but I think it would at least be useful for parsing numbers. Possible other things like booleans as well.

Thanks!

Hey @mthadley, this does indeed seem interesting, but I haven't been able to find a similar approach out there int he wild. All of them seem to just rely on regexes for this.

I'd be more comfortable if there is already a pattern for this out there, so we don't need to come up with our own format. Do you know of any such cases?

[mthadley]

@jbalsas Yea! So Django recently added something like this. Check it out here.

This would actually mean changing Senna and https://github.com/metal/metal-path-parser.

@brunobasto, what are your thoughts on this behavior for the Senna Route class?
