Switching to Puma-dev from Pow for a macOS Rails Environment

Last week, I posted my notes on dropping MAMP in favor of a native environment for my local web development setup. Since I run Rails apps on my local machine, I covered the process for making Apache and pow work side by side.
Well, of course things change. And pretty fast.
That change is the removal of pow and the installation of Puma-dev, a more recent and better maintained Rack server for Rails. Puma-dev even self-describes as, “the emotional successor to pow.” Who am I to argue with that?
Below are my field notes on making the switch. All in all, it was a painless process. The biggest advantage to Puma-dev I’ve noticed so far is its SSL support, getting around the annoying Chrome .dev https issue.
Switching from pow to Puma-dev on macOS
Remove pow
curl get.pow.cx/uninstall.sh | sh
Install Puma-dev
brew install puma/puma/puma-dev
Verify it’s installed
which puma-dev
Setup and configure Puma-dev
sudo puma-dev -setup
Add SSL certificate to appropriate location
security add-trusted-cert -k login.keychain-db ~/Library/Application\ Support/io.puma.dev/cert.pem
Create Puma-dev application directory
mkdir -p ~/.puma-dev
Link your application(s) in the new Puma-dev directory
ln -s /your/app/path
Or, with a dev domain different from the application’s name:
ln -s /your/app/path customdomain
Start Puma-dev
puma-dev
Configure Puma-dev for Apache (optional)
puma-dev -install -install-port 9280 -install-https-port 9283
Open your application in the browser
http://rails-app.dev
https://rails-app.dev
Or, if you have Apache running:
http://rails-app.dev:9280
https://rails-app.dev:9283
If Puma-dev fails to run in the background
launchctl load /Users/[your_username]/Library/LaunchAgents/io.puma.dev.plist
