AWS EBS Node app failing to restart automatically

We have a node application deployed in AWS Elastic Beanstalk (EBS) and when app crashes it is not getting restarted automatically.
We are using nodemon command to run the app. Below is the command in package.json

 "scripts": {
     "start": "nodemon --expose-gc --max-old-space-size=4096 --exec babel-node app.js"
  }

We also have a Procfile which have below content

web: npm start

After app crashes we can see below in eb-engine.log

web: #033[31m[nodemon] app crashed - waiting for file changes before starting..

But app is not restarting. We tried pm2 and forever instead of nodemon but didn't help.

Let me know what we are missing. I couldn't find proper documentation around this topic.

Thanks in advance.

Elastic Beanstalk supports Auto Scaling so you don't need to use nodemon or pm2, but simply start you app as a node application: node app.js.

Now if you want Auto Scaling to replace instances whose application has stopped responding, you can use a configuration file to configure the Auto Scaling group to use Elastic Load Balancing health checks:

Example .ebextensions/autoscaling.config

Resources:
  AWSEBAutoScalingGroup:
    Type: "AWS::AutoScaling::AutoScalingGroup"
    Properties:
      HealthCheckType: ELB
      HealthCheckGracePeriod: 300
