You can use web.json_response:

async def api_server(request):
    res = {"q": "qqq", "a": "aaa"}
    return web.json_response(res)

Furthermore the json_response has additional parameters, like: 

json_response(data, text=None, body=None, status=200, reason=None,
              headers=None, content_type='application/json', dumps=json.dumps)

Most of the parameters are the same as the generic web.Response(..), but the dumps is more interesting: it is a reference to a method that converts data into its JSON equivalent. By default it uses json.dumps. If you however plan to write complex objects to the client, you perhaps should alter that. For now it is fine however.
