# PyWebTransport
[](https://badge.fury.io/py/pywebtransport)
[](https://pypi.org/project/pywebtransport/)
[](https://opensource.org/licenses/MIT)
[](https://github.com/lemonsterfy/pywebtransport/actions)

A high-performance, async-native WebTransport implementation for Python.
## Features
- Full WebTransport protocol implementation (bidirectional streams, unidirectional streams, datagrams)
- High-performance async client and server implementations
- Production-ready connection pooling and load balancing
- Comprehensive monitoring and debugging capabilities
- Type-safe API with complete type annotations
- Extensive test coverage (unit, integration, end-to-end)
## Installation
```bash
pip install pywebtransport
```
For development installation:
```bash
git clone https://github.com/lemonsterfy/pywebtransport.git
cd pywebtransport
pip install -e ".[dev]"
```
## Quick Start
### Server
```python
# server.py
import asyncio
from pywebtransport import ServerApp, ServerConfig, WebTransportSession, WebTransportStream
from pywebtransport.exceptions import ConnectionError, SessionError
from pywebtransport.utils import generate_self_signed_cert
generate_self_signed_cert("localhost")
app = ServerApp(
config=ServerConfig.create(
certfile="localhost.crt",
keyfile="localhost.key",
)
)
async def handle_datagrams(session: WebTransportSession) -> None:
try:
while True:
data = await session.datagrams.receive()
await session.datagrams.send(b"ECHO: " + data)
except (ConnectionError, SessionError, asyncio.CancelledError):
pass
async def handle_streams(session: WebTransportSession) -> None:
try:
async for stream in session.incoming_streams():
if isinstance(stream, WebTransportStream):
data = await stream.read_all()
await stream.write_all(b"ECHO: " + data)
except (ConnectionError, SessionError, asyncio.CancelledError):
pass
@app.route("/")
async def echo_handler(session: WebTransportSession) -> None:
datagram_task = asyncio.create_task(handle_datagrams(session))
stream_task = asyncio.create_task(handle_streams(session))
try:
await session.wait_closed()
finally:
datagram_task.cancel()
stream_task.cancel()
if __name__ == "__main__":
app.run(host="127.0.0.1", port=4433)
```
### Client
```python
# client.py
import asyncio
import ssl
from pywebtransport import ClientConfig, WebTransportClient
async def main() -> None:
config = ClientConfig.create(verify_mode=ssl.CERT_NONE)
async with WebTransportClient.create(config=config) as client:
async with await client.connect("https://127.0.0.1:4433/") as session:
print("Connection established. Testing datagrams...")
await session.datagrams.send(b"Hello, Datagram!")
response = await session.datagrams.receive()
print(f"Datagram echo: {response!r}\n")
print("Testing streams...")
stream = await session.create_bidirectional_stream()
await stream.write_all(b"Hello, Stream!")
response = await stream.read_all()
print(f"Stream echo: {response!r}")
if __name__ == "__main__":
try:
asyncio.run(main())
except KeyboardInterrupt:
pass
```
