Adding routes follows the standard transmute pattern, with a decorator converting a function to an aiohttp route:

import aiohttp_transmute

# define a GET endpoint, taking a query parameter integers left and right,
# which must be integers.
async def multiply(request, name: str, left: int, right: int) -> int:
    return left + right

# append to your route later
aiohttp_transmute.route(app, multiply)

the aiohttp request argument is supported: it will be passed into any function that has ‘request’ in it’s function signature.

see transmute-core:function for more information on customizing transmute routes.

API Documentation


describe is a decorator to customize the rest API that transmute generates, such as choosing certain arguments to be query parameters or body parameters, or a different method.

  • paths (list(str)) – the path(s) for the handler to represent (using swagger’s syntax for a path)
  • methods (list(str)) – the methods this function should respond to. if non is set, transmute defaults to a GET.
  • query_parameters (list(str)) – the names of arguments that should be query parameters. By default, all arguments are query_or path parameters for a GET request.
  • body_parameters (list(str)) – the names of arguments that should be body parameters. By default, all arguments are either body or path parameters for a non-GET request.
  • header_parameters (list(str)) – the arguments that should be passed into the header.
  • path_parameters (list(str)) – the arguments that are specified by the path. By default, arguments that are found in the path are used first before the query_parameters and body_parameters.
