# sparckles/robyn

> Robyn is a Python web framework for building HTTP APIs and web applications. Developers define routes in Python with decorators such as app.get, and the server that handles requests runs on a Rust runtime. Its main language is Python, with Rust underneath.

## Install

From the README: https://github.com/sparckles/robyn#-installation

Clone the robyn repository.
    git clone https://github.com/sparckles/robyn.git

Run the app.py file to start the server on localhost:8080.
    python3 app.py

## How it works

The user-facing API lives in the Python package robyn, where the Robyn app object and its route decorators such as app.get are defined. robyn/__init__.py is the central file that exposes this API, and robyn/router.py handles matching incoming URLs to registered routes. The core runtime is written in Rust under src, and src/types/response.rs defines the response types produced on the Rust side. robyn/robyn.pyi provides type stubs that describe the compiled Rust module to Python tools. Requests enter through the server started by app.start, and the values that handlers return are sent back as responses. Cargo.toml and pyproject.toml define how the Rust and Python parts are built and packaged.
