Tracepanel for JavaScript
See what your Node.js or Bun app does on every request, and what users do on its pages in the browser.
Tracepanel for JavaScript is the @tracepanel/js package. It records each
request of your Node.js or Bun app with its SQL, its calls to Redis, MongoDB
and HTTP APIs, its console output and errors, and sends each trace to the
agent. The agent finds the issues and serves the panel and the console.
npm install @tracepanel/jsIt supports Express, NestJS, Next.js, Nuxt and Bun. For a single-page app on Vite, it puts the panel on the app's pages and records what users do on them, each view and action with the API calls it made.
