Efficient JavaScript GIF Parser and Decoder

gifuct-js is a lean and efficient JavaScript library specifically designed for parsing and decoding GIF files. It aims to overcome the inefficiencies and complexities found in older GIF processing libraries by providing a streamlined API focused solely on extracting raw frame data. The current stable version is 2.1.2, last updated in November 2021. The library prioritizes performance, making it suitable for resource-constrained environments like mobile hybrid applications, as exemplified by its original development for the Ruffle project. It operates by consuming GIF files as `Uint8Array` buffers and leverages `js-binary-schema-parser` internally for robust parsing. A key differentiator is its 'decode-only' approach; unlike many alternatives, it deliberately omits any built-in drawing or rendering logic, empowering developers to integrate GIF data with their preferred rendering engines (e.g., Canvas, WebGL). While it can optionally generate canvas-ready `Uint8ClampedArray` patches, it leaves full control over animation and display to the implementer. The project maintains a stable release cadence, with updates primarily focusing on parsing accuracy and performance enhancements rather than frequent new feature introductions.
