A faster URL dispatcher for aiohttp

The default UrlDispatcher implementation does a linear search every which can have a significant TimeComplexity when dispatching urls when there are a lot of routes. FastUrlDispatcher keeps an index of the urls which allows for fast dispatch.

This library will become obsolete with aiohttp 3.10 as the changes are expected to merge upstream via https://github.com/aio-libs/aiohttp/pull/7829

Installation

Install this via pip (or your favourite package manager):

pip install aiohttp-fast-url-dispatcher

Usage

Attach to a web.Application before any resources are registered.

dispatcher = FastUrlDispatcher()
app = web.Application()
attach_fast_url_dispatcher(app, dispatcher)

Create with a new web.Application

dispatcher = FastUrlDispatcher()
app = web.Application(router=dispatcher)

Caveats

If you have multiple handlers that resolve to the same URL, this module will always prefer the static name over a dynamic name. For example:

app.router.add_get(r"/second/{user}/info", handler)
app.router.add_get("/second/bob/info", handler)

"/second/bob/info" will always be matched before r"/second/{user}/info"
