# When a Mongoose met a MicroPython, part I

**[EmbeddedRelated](https://daily.dev/sources/embeddedrelated)** · 11 min read · 0 upvotes · 0 comments

## Summary

A walkthrough of a lightweight C framework that integrates Cesanta's Mongoose HTTP server with MicroPython, enabling Python callbacks to be invoked from C event handlers. The example demonstrates building and running an HTTP server on Linux (and ESP32 with Docker), handling API endpoints, Basic Auth via a Python credential dictionary, and the MicroPython C API mechanics for converting between C data types and Python objects. Key topics include registering root pointers to prevent garbage collection of callbacks, crafting MicroPython C extension modules, and the event-driven polling loop that lets Mongoose run within a MicroPython main loop.
