userv 0.4.2

Minimalistic core for webserver on microcontroler

The catch

The first start for every webserver is routing and parsing html. This is the core.

Routing

Router objects are simple and are input to the server instances. Example:

from userv.routing import Router, text_response

router = Router()

def test(request):
    return text_response("some text")

router.add("/resturl", test, method="GET")

you can get function test again with:

router.get('/resturl', method="GET")

for creating swagger and so on there is a also a list command:

router.list()

With these object all server are instances and we have full control even without an server instance.

Response types

There are a few build in response types text, json, serving static files although has to be determined by async or normal file pointer usage. There fore these are in the appropriate packages.

The general gist of the response functions is to create a generator which will be used to consumed by your server.

if you want to have full control about your memory flow or need to write a few memory hungry responses feel free to write an response yourself.

Little hint make sure to use the response_header function and end the response with an “\r\n”.

Serve static files

It is pretty simple just add the address with the file you want to serve.

Example:

from userv.routing import static_file

router.add("/index", static_file('boot.py'))

Although the example should never expose your code. It is a prety simple and fast test.

Further packages & webserver

Atm there is an implementation for an socketserver which runs even on on esp8266:

pip install userv.socket_server

And an async server with an exchangable interface.:

pip install userv.async_server
