Introduction

Collie is a fast and simple web framework.

Features 📈

Collie includes the following features commonly found in many frameworks:

• Fully asynchronous
• Support for relational databases, model definition, and migrations (using alembic & sqlalchemy)
• Templates (using Jinja2)
• Efficient request routing (with O(n) complexity; future plans include integration of a very fast Radix Router)
• Authentication support (password hashing, time attack protection)
• CORS
• CSRF (not yet)
• Permissions (not yet)
• Middleware chaining (not yet)
• Global settings
• Command manager (manage.py)
• Support for class-based APIs (serialization/deserialization) and asynchronous caching with TTL.
• Generic views (currently limited to functional views)
• Auto reload
• Background Task Manager

Benchmarks 📈

Tests were conducted using PyPy with a single uvicorn worker. You can also conduct your own tests; here are my results:

$ wrk -t20 -c2000 -d30s http://localhost:8000/login
Running 30s test @ http://localhost:8000/login
  20 threads and 2000 connections
  Thread Stats   Avg      Stdev     Max   +/- Stdev
    Latency   106.93ms   22.84ms 196.04ms   86.61%
    Req/Sec   670.45    273.86     1.34k    58.45%
  280456 requests in 30.04s, 615.80MB read
  Socket errors: connect 999, read 0, write 0, timeout 0
Requests/sec:   9337.11
Transfer/sec:     20.50MB

As you can see, it's blazingly fast even with just a single worker
