Panel
A library for building full web UIs with Web Components using Virtual DOM for state management and rendering.
What is Panel?
Panel is a library that enables developers to build full web UIs using Web Components enhanced with Virtual DOM for rendering and state management. It solves the problem of using Web Components for complex applications by providing a simple, state-driven update cycle and flexible templating options. The library is designed to be pragmatic, avoiding unnecessary abstractions while integrating seamlessly with tools like Redux or RxJS when needed.
Frontend developers building composable, web standards-based applications who want the benefits of Virtual DOM rendering within a Web Components architecture. It's particularly suited for teams looking for a production-tested solution that balances simplicity with power.
Developers choose Panel because it combines the interoperability and future-proofing of Web Components with the performance and developer experience of Virtual DOM, without imposing complex data flow patterns. Its proven track record at scale (e.g., Mixpanel's products) and flexibility in templating and state management make it a reliable choice for modern UI development.
