Choose your technology stack below to get started. Our official SDKs operate asynchronously and will never block your application's critical path.

1

Install the SDK

Download the lognexis-node package via npm or yarn.

npm install lognexis-node
2

Add the Middleware

Initialize the client and add it before your routes.

const express = require('express');
const { expressMiddleware } = require('lognexis-node');

const app = express();
app.use(express.json());

// Add LogNexis monitoring — place BEFORE your routes
app.use(expressMiddleware({
  apiKey: 'YOUR_LOGNEXIS_API_KEY',
  captureBody: true,
  captureHeaders: true,
  excludePaths: ['/health', '/favicon.ico']
}));

app.get('/api/users', (req, res) => {
  res.json({ users: [] });
});

app.listen(3000);

Next Steps
