Monitor your Nuxt.js apps in Atatus

Install Atatus Node.js package.

copy
```
npm install --save atatus-nodejs
```
You need to add NODE_OPTIONS='-r atatus-nodejs/start' to enable Atatus auto instrumentation for the Nuxt.js backend. If you start your Nuxt.js app using package.json, you can update your dev and start npm scripts as follows:
```
// package.json
{
  "scripts": {
    "dev": "NODE_OPTIONS='-r atatus-nodejs/start' nuxt dev",
    "build": "nuxt build",
    "start": "NODE_OPTIONS='-r atatus-nodejs/start' nuxt start",
    "lint": "nuxt lint"
  }
}
```
If you use any other startup script (e.g pm2), add NODE_OPTIONS accordingly.
You can set license key and app name either in ENV variables or atatus-config.js.

a) Environment Variables
```
export ATATUS_LICENSE_KEY="YOUR_LICENSE_KEY"
export ATATUS_APP_NAME="YOUR_APP_NAME"
export ATATUS_ANALYTICS=true
export ATATUS_ANALYTICS_CAPTURE_OUTGOING=true
export ATATUS_LOG_BODY="all"
```
b) atatus-config.js

This file should in the directory where you run your Nuxt.js server.

copy
```
// atatus-config.js
module.exports = {
  licenseKey: "YOUR_LICENSE_KEY",
  appName: "YOUR_APP_NAME",
  analytics: true,
  analyticsCaptureOutgoing: true,
  logBody: "all"
}
```
If this file is not found, you will get the error "License key is missing!". To fix this error, you can set the path of atatus-config.js in the env variable as follows

copy
```
export ATATUS_CONFIG_FILE=/path/to/atatus-config.js
```
Restart your Nuxt.js 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.
