Sometimes the need arises for SSL in local development. We have guides for different webservers, this one is for puma.

0. make sure mkcert is installed

1. create an SSL certificate for localhost with mkcert:

$ mkcert-v1.4.4-linux-amd64 localhost
Created a new local CA 💥
...

2. use the certificate in the Puma config config/puma.rb:

localhost_key = "#{File.join('localhost-key.pem')}"
localhost_crt = "#{File.join('localhost.pem')}"

ssl_bind '0.0.0.0', 3000, {
  key: localhost_key,
  cert: localhost_crt,
  verify_mode: 'none'
}

3. start your server as usual, but go to https://localhost:3000

bundle exec rails s

4. Accept the certificate in your browser
