Right now the gzipped library size is 2KB, 70% of which is path-to-regexp dependency. While path-to-regexp provides a well-known way for developer to describe routes, it seems like we could shrink it's functionality to cover the 99% of use cases.

It would be cool to reimplement a limited subset of the library, so that:

1. We drop that dependency and make it a zero-dependency library 😎
2. We reduce the size to be less than 1KB (current bundle size without a matcher is 686B).

For users who still want to use the path-to-regexp functionality and get an advanced syntax we could provide an optional entry point:

import { Router } from "wouter";
import makeMatcher from "wouter/matcher"; 
import pathToRegexp from "path-to-regexp";

<Router matchFn={makeMatcher(pathToRegexp)}>
  ...
</Router>

So ideally it would be nice to define a subset of features we would like to support. Here are my ideas:

• Always case-insensitive
• Ignores a slash at the end
• Matches an entire path
• Supports named segments /:foo/:bar
• Supports modifiers: :foo?, :foo* and :foo+
• No support for unnamed params. All params should have a name.
• No segment constraints e.g. /:foo(\d+)/
