Code health

5.5out of 10Fair

This codebase scores 5.5 out of 10 for code health, which we rate fair. It also scores maintainability 7.0 and static performance 9.9 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 6 of 97 files are git hotspots, and they average 2.7 — which is where the fixes pay off most.

How pallets/quart works

Applications enter through the Quart application object in src/quart/app.py, which coordinates web application behavior. The ASGI integration in src/quart/asgi.py connects Quart applications to asynchronous servers. Incoming HTTP data is represented through src/quart/wrappers/request.py, while src/quart/helpers.py provides application helper functions. Type definitions and interfaces are collected in src/quart/typing.py. The examples directory provides application examples, and the tests directory exercises the implementation.

The codebase has 97 files and 858 symbols in 4 modules, led by Python and Makefile. Code health is 5.5 out of 10, rated fair.

Getting started with quart

  1. Install quart with pip.

Repowise built this map of pallets/quart from its source and git history. It parses every symbol, draws the dependency graph, scores each file's health from complexity, duplication, coverage and churn, finds hotspots and owners in the history, and writes documentation for every module. Your coding agent reads the same index over MCP, so its answers cite real files.
