Getting Started

Make sure you have both pip and at least version 3.5 of Python before starting. Sanic uses the new async/await syntax, so earlier versions of python won't work.

1. Install Sanic

pip3 install sanic

To install sanic without uvloop or ujson using bash, you can provide either or both of these environmental variables using any truthy string like 'y', 'yes', 't', 'true', 'on', '1' and setting the SANIC_NO_X (X = UVLOOP/UJSON) to true will stop that features installation.

SANIC_NO_UVLOOP=true SANIC_NO_UJSON=true pip3 install sanic

2. Create a file called main.py

from sanic import Sanic
from sanic.response import json

app = Sanic()

@app.route("/")
async def test(request):
    return json({"hello": "world"})

if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

3. Run the server

python3 main.py

4. Check your browser

Open the address http://0.0.0.0:8000 in your web browser. You should see the message Hello world!.

You now have a working Sanic server!
