Step 1: Create instrumentation file

instrumentation.ts File can be js too with any name, any path.

process.env.OTELIC_API_KEY = "Get your free API KEY at https://app.otelic.com";
process.env.OTELIC_APP_NAME = "NodeJS App";
process.env.OTELIC_SERVICE_NAME = "My Service";
process.env.OTELIC_SERVICE_VERSION = "v1";

import "@otelic/open-telemetry";

Step 2: Load instrumentation before main app with -r

This works with JavaScript and TypeScript

package.json

{
  "scripts": {
    "start": "node -r ./instrumentation.ts app.ts"
  }
}

The -r flag in Node.js stands for --require, and it allows you to preload a module before your main script runs.

If you need to preload multiple modules before your app, just use -r multiple times like so: node -r instrumentation.js -r else.js app.js

You can preload multiple modules with multiple -r flags:

  node -r ./instrumentation.ts -r ./otherSetup.ts app.ts
