Deployment on AWS Elastic Beanstalk

1. Ensure your project contains:
   • package.json, index.js, Procfile, .env.example, .ebextensions/, .platform/hooks/postdeploy/
2. Create a Procfile (if it does not exist):

   web: node index.js
   

3. Zip the contents of your project directory (do not zip the root folder, only the files and subfolders inside).
4. Upload the ZIP to Elastic Beanstalk using the AWS Console.
5. Set environment variables in the EB console or via .ebextensions/env.config.
6. (Optional) Configure a custom domain:
   • Point your domain to the EB environment (A or CNAME record).
   • Edit .platform/hooks/postdeploy/01_certbot_ssl.sh and set DOMAIN and EMAIL.
   • The script will automatically obtain an SSL certificate from Let's Encrypt after deployment.

SSL and Custom Domain

• HTTP→HTTPS redirection is configured in .ebextensions/https-redirect.config.
