Fusée Framework

Fusée is a JavaScript framework, currently at v1.6.0, designed for high-performance and fine-grained reactivity. It emphasizes a "signals-first" approach, where atomic updates ensure only modified DOM parts are rendered, aiming for peak performance. The framework features a recursive, non-greedy compiler for efficient node traversal and a strict component system that includes prop validation, lifecycle hooks like `onMount` and `onUnmount`, and automated cleanup. It also provides optimized directives such as `f-if`, `f-for`, and `f-model`, alongside a `Performance Shield (f-once)` for stabilizing static subtrees. Fusée integrates with Vite for a fast development workflow and offers a comprehensive CLI for project scaffolding, supporting both JavaScript and TypeScript templates. It differentiates itself through its custom compiler and strong focus on explicit performance optimizations, backed by a robust test suite covering reactivity, components, dependency injection, and type safety. There's no fixed release cadence mentioned, but updates appear regular.
