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: python3 -m pip install sanic
2. Create a file called main.py with the following code:

from sanic import Sanic
from sanic.response import text

app = Sanic(__name__)

@app.route("/")
async def test(request):
    return text('Hello world!')

app.run(host="0.0.0.0", port=8000, debug=True)

3. Run the server: python3 main.py
4. 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!
