Slim.js is an ultra-lightweight (~3KB gzipped) front-end micro-framework for building native Web Components with declarative templates and reactive data binding. It uses standard browser APIs like CustomElementsRegistry and HTMLElement inheritance with no compilers or external dependencies.

Use cases

• build web components with declarative templates
• create custom HTML elements with data binding
• add reactive UI components to an existing app without a full framework
• write framework-agnostic components usable alongside React, Vue, or Angular
• build lightweight UIs without a build step or compiler
• create reusable render-only components with minimal JavaScript

When to choose

• you want native Web Components with tiny footprint and no build tooling
• you need components interoperable with any other framework
• you prefer direct DOM manipulation without a virtual DOM layer
• you want opt-in directives and shadow DOM control

When to avoid

• you need a large ecosystem with routing, state stores, and devtools out of the box
• you want a large community and frequent updates - the project has low recent activity
• you need server-side rendering or SSR support
• your team prefers mainstream frameworks with extensive hiring pools
