wiljs

WilJS is a JavaScript library intended for building web user interfaces. It offers a lightweight, component-based architecture with reactive state and a small rendering engine that updates the DOM efficiently. Designed to be framework-agnostic, WilJS aims to be easy to integrate into existing projects while remaining performant and approachable for newcomers.

At its core, WilJS centers on components, state management, and rendering. Components encapsulate logic and markup, and state changes automatically trigger re-renders through a reactive data model. The library provides a templating system or declarative rendering approach, together with lifecycle hooks, event handling, and support for composing components. The API surface is intentionally small to reduce complexity, while extensibility through plugins or directives is supported to adapt to various use cases.

Usage typically involves defining components, initializing application state, and mounting the root component to a DOM element. WilJS exposes utilities for creating, updating, and unmounting components, and it is designed to work alongside other libraries and build tools. The project has an active maintenance cycle in online repositories and documentation that covers installation, patterns for data flow, accessibility considerations, and testing strategies.
