Deep dives
Court: The Async Version of Flask
Court, the fully async version of Flask, was created by Philip Jones in collaboration with the Flask team. It enables leveraging async capabilities in Flask projects, offering compatibility with async features.
Court Extensions and Libraries
Philip Jones shared the top court extensions and libraries that enhance web applications. These extensions provide additional functionalities like CORS policies, session management, rate limiting, form handling, and CSRF tokens to streamline development.
Key Court Extensions: CORS, Auth, Rate Limiting, and WTForms
Prominent Court extensions discussed include CORS for controlling cross-origin resource sharing, Auth for secure cookie-based session management, Rate Limiting for imposing request limits, and WTForms for simplifying form handling and validation, aiding in efficient web development.
FastAPI-Like Data Validation with Schemas
Schemas for APIs have evolved to streamline data validation processes, akin to FastAPI's model binding. By defining expected data structures, called schemas, APIs validate incoming requests. The 'validate request' decorator checks if incoming data matches the specified schema; if not, a 400 response is returned.
Background Task Execution with Async Event Loop
A recent release introduces background task execution within the async event loop, eliminating the need for additional infrastructure like cron jobs. Tasks can be asynchronous or thread-based to prevent blocking the event loop. Custom storage options allow task persistence across server downtimes for reliable task execution.
