Where to Find Components Compatible with ASGI?

The integration of modern asynchronous technologies into web development necessitates the availability of compatible components that ensure maximum performance and scalability. ASGI (Asynchronous Server Gateway Interface) has become a crucial standard for asynchronous web applications in Python, and finding compatible components for this environment is a key step for successful implementation.

ASGI Servers

  1. Uvicorn: A lightning-fast ASGI server built on top of uvloop and httptools. It’s known for its speed and efficiency, making it an excellent choice for deploying ASGI applications.
    • Website: Uvicorn
    • Installation: pip install uvicorn
  2. Daphne: The original ASGI server developed as part of the Django Channels project. It is designed to handle HTTP, HTTP2, and WebSocket protocols.
    • Website: Daphne
    • Installation: pip install daphne
  3. Hypercorn: An ASGI server based on the sans-io approach, supporting HTTP/1, HTTP/2, and WebSockets.
    • Website: Hypercorn
    • Installation: pip install hypercorn

ASGI Frameworks

  1. Starlette: A lightweight ASGI framework/toolkit that is perfect for building high-performance async web services.
    • Website: Starlette
    • Installation: pip install starlette
  2. FastAPI: A modern, fast (high-performance), web framework for building APIs with Python 3.6+ based on standard Python type hints.
    • Website: FastAPI
    • Installation: pip install fastapi
  3. Django Channels: Adds a layer to Django to handle WebSockets, HTTP2, and other protocols that require long-lived connections.
    • Website: Django Channels
    • Installation: pip install channels

ASGI Middleware

Middleware components can be added to ASGI applications to process requests and responses, providing functionalities such as authentication, logging, and more.

  1. starlette.middleware: Starlette includes several built-in middleware components for tasks like session handling, CORS (Cross-Origin Resource Sharing), and GZip compression.
    • Documentation: Starlette Middleware
  2. fastapi.middleware: FastAPI also provides middleware support for adding functionalities like CORS handling, HTTPS redirection, and more.
    • Documentation: FastAPI Middleware

Deployment Tools

For deploying ASGI applications, there are several tools and services available that are compatible with ASGI.

  1. Mangum: An adapter that allows you to run ASGI applications on AWS Lambda, enabling serverless deployment of your applications.
    • Website: Mangum
    • Installation: pip install mangum
  2. AWS Elastic Beanstalk: Supports deployment of ASGI applications using containers or custom environments.
    • Website: AWS Elastic Beanstalk
