)


dp = ApiDispatcher()


@dp.get('api/<str method>')
async def api(request: AsyncRequest, method: str) -> HttpResponse:
    return HttpJSONResponse(
        status='ok',
        method=method,
        ip=request.ip
    )

@dp.get()

Begin project

Standart

slinn-admin create-project www
cd www
venv/bin/activate
slinn create-app localhost host=localhost host=127.0.0.1

Insert example into localhost/app.py file, then run start.bat or start.sh script

[!TIP] Instead of use example, create app from template slinn template example

Expected output

Loading config...
Apps: firstrun
Debug mode enabled
Smart navigation enabled

Starting server...
HTTP server is available on http://localhost:8080/

To config project you should edit ./project.json

To config app you should edit ./%app%/config.json

Classic

Unix-like (Linux, MacOS, FreeBSD...):

mkdir helloworld 
cd helloworld
python3 -m venv venv
venv/bin/activate

Windows:

mkdir helloworld 
cd helloworld
python3 -m venv venv
venv\Scripts\activate

Insert example into ./example.py and add following code:

from slinn import AsyncServer
import asyncio
asyncio.run(AsyncServer(dp).listen(Address(8080)))

then write python example.py

Excepted output

helloworld $ venv/bin/python example.py
