• Response_ -- Send HTTP (text, html, json, stream, sse, file, http errors) responses
• ResponseWebsocket_ -- Work with websockets
• RequestMiddleware_ -- Parse a scope and insert the parsed request into the scope
• ResponseMiddleware_ -- Parse responses and convert them into ASGI messages
• RouterMiddleware_ -- Route HTTP requests
• LifespanMiddleware_ -- Process a lifespan cycle
• StaticFilesMiddleware_ -- Serve static files from URL prefixes
• asgi_tools.tests.TestClient <https://klen.github.io/asgi-tools/api.html#testclient>_ -- A test client with websockets support to test asgi applications
• App_ -- A simple foundation for ASGI apps

.. _requirements:

Requirements

• python >= 3.9

.. note:: pypy3 is also supported

ASGI-Tools belongs to the category of ASGI_ web frameworks, so it requires an ASGI HTTP server to run, such as uvicorn_, daphne_, or hypercorn_.

.. _installation:

Installation

asgi-tools should be installed using pip: ::

pip install asgi-tools

A Quick Example

You can use any of ASGI-Tools components independently.

Dispite this ASGI-Tools contains App_ helper to quickly build ASGI applications. For instance:

Save this to app.py.

.. code-block:: python

from asgi_tools import App

app = App()

@app.route('/')
async def hello(request):
    return "Hello World!"

Run it with uvicorn

.. code-block:: sh

$ uvicorn app:app
