Show HN: PraxisJS – signal-driven front end framework and AI experiment

mateusgx Sunday, March 01, 2026

I built PraxisJS, a signal-driven frontend framework exploring what a more explicit and traceable architecture could look like.

PraxisJS started as a personal project. It reflects a single perspective on frontend design, not a committee decision, not a consensus. I wanted to see how far you can push explicitness before it becomes friction.

Most frameworks optimize for writing less. PraxisJS questions that tradeoff. @State doesn’t suggest reactivity, it is reactive, visible in the code. Signals reach the DOM without a reconciliation layer in between (the renderer is still evolving toward that goal).

It also became an AI-assisted experiment, not to automate thinking, but to pressure-test ideas. Some parts came from that collaboration. Some exist because it failed.

v0.1.0 beta, experimental, not production-ready. But the ideas are real.

Summary
Praxis is an open-source JavaScript framework that enables the rapid development of web applications, offering a modular architecture, performance-oriented design, and a focus on developer experience.
