How to deploy Expressjs application using AWS Opsworks?

expressjs_deployment_using_opsworks.txt

1. Login to your aws account.
2. Visit Opsworks, https://console.aws.amazon.com/opsworks/home.
3. Create new stack.
4. In Stack's Configuration Management, provide the following custom JSON:
{
  "environment_variables": {
    "NODE_ENV": "production"
  },
  "deploy": {
    "YOUR_APP_NAME": {
      "environment_variables": {
        "NODE_ENV": "production",
        "PORT": "80"
      }
    }
  }
}

Note: Nodejs Opsworks require your app to run in port 80 and 443(for https).

5. Add Node.js App Server Layer to the newly created stack.
6. Add new App with Node.js Type and provide your application source.
7. If you generate your application using Express generator, e.g. 'express YOUR_APP_NAME', your app will run using bin/www file.
However, Nodejs Opsworks require you to have server.js to run your application. Hence, we need to copy bin/www file to 'YOUR_APP_NAME'/server.js .
8. Deploy App.

That's all folks. Happy Coding.
