## Description

Quart is an asynchronous Python web framework that implements the ASGI specification. It is used to build high-performance HTTP and WebSocket services, JSON REST APIs, and web applications using async and await syntax for non-blocking request handling.

The framework supports persistent bidirectional communication via WebSocket API servers and enables the proactive delivery of assets through HTTP server push. It also includes a template engine for rendering dynamic HTML web pages and supports incremental request and response streaming to manage large payloads.

General capabilities cover request routing, JSON response generation, cookie management, and application configuration. The framework also provides a test client for asynchronous endpoint testing and supports deployment to serverless environments.
