Critical Stimulus: Simplify Complex Interactions
A JavaScript framework for simplifying complex user interactions on web pages using a declarative syntax and binding DOM elements to controllers
What is Critical Stimulus?
Critical Stimulus is an open-source JavaScript framework created by the Basecamp team. It is designed to add behavior to web pages by binding DOM elements to JavaScript controller classes.
Some key features of Critical Stimulus include:
- Declarative syntax - You declaratively associate DOM elements with controller classes using HTML data attributes. This avoids having to query the DOM from JavaScript.
- Slim controllers - Controllers focus on specific jobs. This keeps them small, reusable and testable.
- No dependencies - Critical Stimulus has no external dependencies and aims to have a small footprint.
- Module system - The framework utilizes ES6 modules and supports tree-shaking for optimized payload size.
- Integrates with frameworks - It can integrate cleanly with popular frameworks like Rails, React, Angular and Vue.
Critical Stimulus allows you to add dynamic behavior to a page while keeping your JavaScript simple and focused. Common use cases include tabs, accordions, typeaheads, modals, etc. Its minimalist approach shines when enhancing HTML created on the server side.
