Flight is a JavaScript component framework and DOM interactivity library used to map behavioral logic to HTML nodes. It provides an event-driven architecture for building modular user interface elements and managing web application interactivity.
The library distinguishes itself through a mixin-based system for injecting reusable functions and properties into components, promoting code reuse without rigid inheritance. It further enables behavior modification via function hooking, allowing developers to wrap existing methods to inject custom logic without altering the original source code.
The framework covers several core capability areas, including decoupled event communication for component interaction, lifecycle management to prevent memory leaks during teardown, and execution rate limiting through debouncing and throttling. It also includes utilities for scoped internal element querying and event sequence tracing for debugging application behavior.
