NestJS APM Integration

Installation & Setup for NestJS

Install Atatus Node.js package.

copy
```
npm install --save atatus-nodejs
```

Create atatus.js file in your project root with the following code:

copy

// atatus.js - Atatus Agent Initialization

import * as atatus from 'atatus-nodejs';

atatus.start({
    licenseKey: "YOUR_LICENSE_KEY",
    appName: "YOUR_APP_NAME",
    analytics: true,
    analyticsCaptureOutgoing: true,
    logBody: 'all'
});

export default atatus;

Start your NestJS application using one of these methods:

Option 1: Using -r flag (recommended)

copy
```
node -r ./atatus.js dist/main.js
```
Option 2: Using NODE_OPTIONS environment variable

copy
```
NODE_OPTIONS='-r ./atatus.js' npm run start:prod
```
Or update your package.json scripts:
```
{
  "scripts": {
    "start:prod": "NODE_OPTIONS='-r ./atatus.js' node dist/main.js"
  }
}
```

Build and Start your NestJS server.

Just restart your server and access it from your web app or mobile app or curl. You will visualize your application's metrics within minutes.

Important: For NestJS/TypeScript, use import * as atatus from 'atatus-nodejs' instead of the default import.
