Nanoweb is a full asynchronous web server for micropython created in order to benefit from a correct ratio between memory size and features.

It is thus able to run on an ESP8266, ESP32, Raspberry Pico, etc...

• Completely asynchronous
• Declaration of routes via a dictionary or directly by decorator
• Management of static files (see assets_extensions)
• Callbacks functions when a new query or an error occurs
• Extraction of HTML headers
• User code dense and conci
• Routing wildcards

You just have to copy the nanoweb.py file on the target (ESP32, Nano, etc...).

See the example.py file for an advanced example where you will be able to:

• Make a JSON response
• Use pages protected with credentials
• Upload file
• Use DELETE method
• Read POST data

And this is a simpler example:

import uasyncio from nanoweb import Nanoweb naw = Nanoweb() async def api_status(request): """API status endpoint""" await request.write("HTTP/1.1 200 OK\r\n") await request.write("Content-Type: application/json\r\n\r\n") await request.write('{"status": "running"}') # You can declare route from the Nanoweb routes dict... naw.routes = { '/api/status': api_status, } # ... or declare route directly from the Nanoweb route decorator @naw.route("/ping") async def ping(request): await request.write("HTTP/1.1 200 OK\r\n\r\n") await request.write("pong") loop = asyncio.get_event_loop() loop.create_task(naw.run()) loop.run_forever()
