Configuring HTTPS for Local Development

Service workers require a secure context (https://) to function.

While Rails applications typically use http://localhost:3000, we need HTTPS for PWA development.

Run the following command to generate a local SSL certificate:

mkdir -p config/ssl
openssl req -x509 -newkey rsa:2048 -keyout config/ssl/key.pem -out config/ssl/cert.pem -days 365 -nodes -subj "/CN=localhost"

This generates a key and certificate valid for one year.

Modify config/puma.rb to use the certificate:

ssl_bind '127.0.0.1', '3001', {
  key: "config/ssl/key.pem",
  cert: "config/ssl/cert.pem"
}

Start the server with:

bin/rails s -b 'ssl://127.0.0.1:3001?key=config/ssl/key.pem&cert=config/ssl/cert.pem'

Now, your local Rails app runs at https://127.0.0.1:3001 with HTTPS enabled.
