Catalyst is a small TypeScript library from GitHub that simplifies building Web Components using decorators, targets, and data-action bindings. It provides patterns and helpers for structuring components within complex applications.
Use cases
- build custom elements with less boilerplate
- use decorators with web components
- bind DOM events to component methods
- manage element targets in web components
- structure frontend components in a large app
When to choose
- you want lightweight Web Components without a full framework
- you like Stimulus-style declarative bindings
- your stack is TypeScript and standards-based DOM
When to avoid
- you need a full reactive UI framework with state management
- you don't use TypeScript or decorators
- you need server-side rendering out of the box
