@overcast/node

Overcast SRE monitoring SDK for Node.js. One install, one line — captures everything.

Install

npm install @overcast/node

Usage

require('@overcast/node').init({ apiKey: 'oc_...', serviceName: 'my-api' });

That's it. The SDK automatically captures:

• All console.log/info/debug/warn/error output
• Uncaught exceptions and unhandled promise rejections
• All outgoing HTTP/HTTPS requests (status, latency, request/response bodies)
• Process warnings and deprecations
• Memory usage, event-loop lag, handle leaks
• Stack traces with full context

Express Middleware (optional)

const overcast = require('@overcast/node');
overcast.init({ apiKey: 'oc_...' });

const app = express();
app.use(overcast.middleware()); // Captures all incoming requests
