What it is

Starlette is a lightweight ASGI framework for building async web services in Python. It provides HTTP routing, WebSocket support, middleware (CORS, GZip, sessions), background tasks, and a test client—all with minimal dependencies and 100% type coverage. It's positioned as the foundation layer beneath higher-level frameworks like FastAPI. Monolithic design: starlette/ contains all core modules organized by concern (routing.py, middleware/, requests.py, responses.py, websockets.py, testclient.py). Middleware is pluggable via starlette/middleware/. Tests and docs are external (mkdocs.yml suggests Markdown-driven docs). Uses uv.lock for dependency pinning and pyproject.toml for modern Python…

Start here

Read these in order:

• starlette/exceptions.py — Foundation: doesn't import anything internally and is imported by 19 other files. Read first to learn the vocabulary.
• starlette/middleware/__init__.py — Foundation: imported by 18, no internal dependencies of its own.
• starlette/concurrency.py — Built on the foundation; imported by 8 downstream files.
• starlette/status.py — Built on the foundation; imported by 0 downstream files.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/Kludex/starlette.git
cd starlette
# Install with uv (modern Python package manager) or pip
uv sync  # or: pip install -e .
pip install uvicorn  # Required ASGI server

Daily commands:

uvicorn main:app --reload

(From README example: creates a starlette.applications.Starlette instance named 'app' and serves it via Uvicorn ASGI server on localhost:8000.)

Key cautions & unknowns

• Concentrated ownership — top contributor handles 62% of recent commits
• No required environment variables are evident in the file list. However: (1) The testclient.py depends on httpx being installed—tests will fail silently if it's missing despite being optional in pyproject.toml. (2)…
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
