• Transparently and losslessly handle all proxy requests,
• Asynchronous streaming transfer, support file proxy.

other features

• Strict linting and strict-mode Pyright type checking.
• 100% Type Completeness, Code coverage of over 95%.
• Forced keep-alive connections, minimizing proxy latency.
• Handle errors as gracefully as possible.

FastAPI Proxy Lib stands on the shoulders of giants

• httpx for HTTP proxy
• httpx-ws for WebSocket proxy

So, it perfectly supports all features of httpx.AsyncClient, you can even use your custom AsyncClient, Transport.

Installation

!!! note

We follow semantic versioning.<br>
This is a young project, and before 1.0.0, there may be changes in the API (though we try to avoid that).<br>
We recommend pinning to any minor versions, such as 0.1.x.

Pypi will come soon, please install from github temporarily:

pip install fastapi-proxy-lib[standard]@git+https://github.com/WSH032/fastapi-proxy-lib.git

Perhaps you've noticed that we're installing fastapi-proxy-lib[standard] instead of fastapi-proxy-lib. The difference is:

• The former will install FastAPI at the same time.
• The latter installs only the basic dependencies for fastapi-proxy-lib.

If you only need to use this library with Starlette, you only need to install the latter.

Quick start

With the helper functions, get the FastAPI proxy server app is very convenient and out of the box:

from fastapi_proxy_lib.fastapi.app import reverse_http_app

app = reverse_http_app(base_url="http://www.example.com/foo/")

That's all! Now, you can launch the proxy server with uvicorn:

uvicorn main:app  --host 127.0.0.1 --port 8000

Then, visit http://127.0.0.1:8000/bar?baz=1, you will get the response from http://www.example.com/foo/bar?baz=1.

For support with FastAPI router or only using Starlette, please visit to our documentation 📚 for more details.
