grych/drab

Drab is a framework for building interactive, real-time web applications within the Phoenix ecosystem. It enables server-side Elixir code to directly manipulate the browser's DOM, manage live-updating templates, and handle user events without requiring custom JavaScript. The system provides a comprehensive suite of tools for state management, presence tracking, and template rendering, supported by an automated installation process and extensive test infrastructure.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 20 July 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 27132d9be7 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.17. Score the same commit under that rubric and you get the same number.
