On this page

How to set up your environment
How to your application using the infrastack.ai SDK or the official OpenTelemetry SDK

Follow the example project on GitHub

You can use the Infrastack SDK to instrument your Express.js application with a single line of code.

Install the NPM package

npm install @infrastack/otel

Prepare your environment

Export your API key as an environment variable.

export INFRASTACK_API_KEY=sk-1*************************f5af

Or you can set the environment variables in your .env file by using the dotenv library.

Create instrumentation.ts

instrumentation.ts

import { Infrastack } from "@infrastack/otel"; 
Infrastack.init({
  serviceName:"YOUR_SERVICE_NAME",
});

If you don’t provide a service name, we will create a random name for you.

Build and run your application

Run your Express.js application with the node required command.

npx tsc && node -r ./dist/instrumentation.js dist/index.js

After creating some traffic, you can check your data from the infrastack.ai dashboard.
