# miguelgrinberg/microdot

> Microdot is a minimalistic web framework for Python and MicroPython, inspired by Flask. It lets developers map URLs to handler functions, which receive a request and return a response. Because it is small, it can run on systems with limited resources such as microcontrollers. Its main language is Python.

## How it works

Application code creates a Microdot object and registers handler functions with its route decorator, which matches URL patterns and HTTP methods. The core framework lives in src/microdot/microdot.py, which dispatches each incoming request to the matching handler. The typings/microdot directory declares type contracts for protocol adapters for WSGI and ASGI, and for features such as authentication, CORS and CSRF protection. For MicroPython targets, libs/micropython and libs/circuitpython provide the module support the framework relies on, and libs/circuitpython/asyncio/core.py defines the scheduling and event loop primitives used by async code. The examples/subapps/app.py file shows how sub-applications are composed into a larger app.
