⚡️ Hotwire dev newsletter - July 2022 edition

A curated, monthly roundup of the best Turbo (Native), Stimulus, and Strada articles, code, courses, and more by Joe Masilotti.

Welcome back to the July edition of the ⚡️ Hotwire dev newsletter! This newsletter was sent to almost 2000 developers – I appreciate each and every one of you. 🤗

If you missed RailsConf this year now’s your chance to catch up on the recordings. All 67 videos have been uploaded to YouTube. Not sure where to start? I list my favorite talks below.

Speaking of YouTube, I’m doing my first Turbo Native live stream later today. And I’d love if you could come and say hi! I’ll be fielding questions at the end if you have anything you’d like to ask.

We also have so much content from Matt Swanson he gets his own section this month. 😆

🎖 Achievement unlocked!

I hit a big achievement last week: shortest time from project kick-off to live in the App Store. I ported a client’s Ruby on Rails app to iOS and we went live in the App Store in 7 short weeks. 🎉

This is a huge milestone because it gets me closer to my dream of helping more folks get their businesses on iOS. I wrote about the process on my blog diving into how it worked, the shortcuts we used, and how it all fit together.
