This project allows you to execute a list of http operations asynchronously from within a synchronous context.

Overview

This project allows you to execute a list of http operations asynchronously from within a synchronous context.

It does not care whether you should do this. It simply allows you to do so if you desire.

Installing

The package is available via pip.

pip install loamy

If you're not on Windows, install the uvloop extra to increase performance.

pip install "loamy[uvloop]"

Usage

The package can be imported as shown:

from loamy.session import Clump, RequestMap, RequestResponse

Class	Description
Clump	Container object that stores collection of requests (type RequestMap) to send
RequestMap	Container object that stores all info about an individual request to send
RequestResponse	Container object that stores the request response and any exception raised for each individual request

Example

# Create RequestMap objects
req1 = RequestMap(
    url="https://baconipsum.com/api",
    http_op="GET",
    query_params={"type": "meat-and-filler", "format": "json"},
)
req2 = RequestMap(
    url="https://baconipsum.com/api",
    http_op="GET",
    query_params={"type": "all-meat", "format": "json"},
)
req3 = RequestMap(
    url="https://baconipsum.com/api",
    http_op="GET",
    query_params={"type": "meat-and-filler", "format": "json"},
)

# Create Clump and call send_requests()
session = Clump(requests=[req1, req2, req3])
responses: list[RequestResponse] = session.send_requests(return_exceptions=True)


# Handle responses for individual requests
for resp in responses:
    http_verb = resp.request_map.http_op
    print(f"Evaluating response for {http_verb} request to {resp.request_map.url}")
    if resp.error is not None:
        print("Exception raised for request")
    else:
        print(f"Status Code: {resp.status_code}")
        if resp.body is not None:
            print(resp.body)

    body: dict | None = None
    query_params: dict[str, str] | None = None
    headers: dict[str, str] | None = None

RequestResponse Class

class RequestResponse(msgspec.Struct):
    request_map: RequestMap
    status_code: int
    body: dict | None = None
    error: BaseException | None = None
