router

A typical web server looks like a function of type

(request: Request) => Promise<Response>

for some types Request and Response.

This is a minimal tool for defining and combining such functions.

See readme.test.ts for an example application.

Request

The Request type can be any record, but this library assumes a few special attributes:

• method: string - The HTTP request method.

• path: string | null - A relative URL pathname constructed from the request path, (e.g. as new URL(request.url).pathname.slice(1) to remove the leading slash but perhaps modified by intermediate processing before reaching the server).

• parent: string - When descending into a dynamicDirectory, the segment that was popped off the front of the URL path.

Response

The Response type can be anything.
