Zero

A toolkit for building web components in ClojureScript.

Highlights

• Depends only on ClojureScript core
• Small, with optional 'extras' modules for more features
• Hot reload friendly
• Focus preserving updates
• 'Good enough' performance

Rationale

• Web components have many advantages over React and similar frameworks, including:
  • Easy to render server-side
  • Seamless interop with other frameworks and libraries
  • Encapsulation, no style bleed, often better performance
  • Native DevTools support
• Web components are cool, but the native API for building them isn't very convenient
  • Zero makes web components easy

Warning

Depends on modern browser APIs, works on the latest versions of all major browsers... but will break in some not-so-old versions. In particular, it depends on:

• CSSStyleSheet constructor
• ElementInternals

Learning

Check out the Zero User's Guide for a (reasonably) complete guide. Also, there are a few demos:

• TodoMVC
• SSR Demo (w. live updates)
