# uHTTP: micro HTTP server
## Features:
- support MicroPython and also cPython
- minimalist and low level implementation using posix sockets
- is fully synchronous (not uses ASYNC or multiple threads) but can work with multiple connections
- support delayed response, user can hold client instance and reply later
- support for raw data (HTML, binary, ...) and also for JSON (send and receive)
- need at least 32KB RAM to work (depends on configured limits)
- do many check for bad requests and or headers, and many errors will not break this
## usage
```python
import uhttp
server = uhttp.HttpServer(port=9980)
while True:
client = server.wait()
if client:
if client.path == '/':
# result is html
client.respond("
hello
uHTTP
")
elif client.path == '/rpc':
# result is json
client.respond({'message': 'hello', 'success': True, 'headers': client.headers, 'query': client.query})
else:
client.respond("Not found", status=404)
```
