To define your API, you can add the following code in an app.py file.
from robyn import Robyn
app = Robyn(__file__)
@app.get("/")
async def h(request):
return "Hello, world!"
app.start(port=8080)Simply run the app.py file you created. You will then have access to a server on the localhost:8080, that you can request from an other program. Robyn provides several options to customize your web server.
$ python3 app.py
To see the usage
usage: app.py [-h] [--processes PROCESSES] [--workers WORKERS] [--dev] [--log-level LOG_LEVEL]
