Announcing Starbeam: Universal Reactivity – Yehuda Katz, JSNation 2022

StarBeam, a new library for building reactive user interfaces, automatically updates the UI when the underlying data changes. It's framework-agnostic, works with React, Svelte, Vue, and Ember, and includes a debugging tool.

Key takeaways
  • StarBeam is a library for building reactive user interfaces based on the guiding principle of “write normal JavaScript code, get more reliable user interfaces.”
  • It uses a dependency tracking system to automatically update the UI when the underlying data changes.
  • StarBeam can be used with React, Svelte, Vue, and Ember.
  • It provides a debugging tool that allows you to see exactly what caused a UI update.
  • StarBeam is still in development, but it has the potential to make it much easier to build complex reactive UIs.
  • It is not a new framework, but rather a library that can be used to add reactivity to existing frameworks.
  • StarBeam uses a declarative approach to UI development, which makes it easier to reason about the code.
  • It is designed to be easy to use, even for developers who are new to reactive programming.
  • StarBeam is open source and available on GitHub.
