Optimistic UI in Rails with optimism... and Inertia—Martian Chronicles, Evil Martians’ team blog Build optimistic UI in Rails with Inertia by updating props before requests complete. Learn the replaceProp pattern, automatic reconciliation, rollback behavior, and history caveats using a kanban boa...

Optimistic UI is a lie. And the modern web has trained everyone to expect interfaces that lie convincingly. In this new post, see how with Inertia Rails, telling that lie takes remarkably little code because of how Inertia handles state:

Rails Frontend Evolution: It Was a Setup All Along by Evil Martians Remember when Rails dominated the frontend, then seemingly retreated to API-only mode? Plot twist: that wasn't Rails giving up—it was setting the stage for a triumphant return.

I love profiling code, it's genuinely fun. Used github.com/Shopify/heap... today and spotted a bottleneck in Typelizer. After fixing it, memory usage dropped by 150x and type generation is now 5x faster. Pure joy.

Hello! @tropicalonrails.bsky.social kicks off tomorrow in Sãn Paulo, Brazil! @inazarova.bsky.social will deliver the opening keynote remotely and @skryukov.dev will deliver his talk in person. Come say hello, olá, or just give a 👋!

Deployed a huge update for a client yesterday that re-writes their frontend to use Inertia + Rails.

After working with Inertia the past couple of months, it's really been growing on me.

Yesterday we (mostly) moved all of Hardcover's front-end from Next.js hosted on Google Cloud Run to Ruby on Rails and Inertia.js. Aside from a some bumps and missed parts, it's been a smooth rollout!

Some work to do on PageSpeed, but not bad so far.

Using inertia-rails to use React instead of Hotwire in a new project. So easy to setup. I was overthinking it for so long.

Oh, how I've you missed you 🥹

Can't wait to give a talk on Inertia.js at Tropical on Rails this April. Meet you there! 🌴

Turbo Mount React - StackBlitz A Vite React project based on react-dom, react, turbo-mount, @vitejs/plugin-react and vite

Modified Turbo Mount plugin

Last week, we received an intriguing feature request for Turbo Mount: using a React component to wrap a server-side rendered Rails form. How cool is that?

Here's the solution: just a few lines of JS in a custom Turbo Mount plugin. Should we add this as a built-in plugin? What do you think?

Railsmas on Mars: 12 Days of Mandatory Developer Joy and Challenge—Martian Chronicles, Evil Martians’ team blog Over 12 days, we’ll unwrap 12 small (but mighty) approaches designed to level up your Rails apps. We’ll discuss, then suggest hands-on practice!

We're 4 days into the Railsmas, where we propose developer productivity ideas for your holiday table daily: libyears, Vernier, Ruby LSP (and how to extend it with custom addons), and tricks against flaky tests. Do you like any? Suggest your own! evilmartians.com/chronicles/r...

On this third day of Railsmas: an overlooked treasure for those who think their IDE already has everything. Open your mind, read, and see if you might just think twice about Ruby-LSP as a sign of productivity miracles yet to come. evilmartians.com/chronicles/r...

Over 12 days, we’re unwrapping 12 small (but mighty) approaches designed to level up your Rails apps. We’ll discuss, then suggest hands-on practice! First up, we talk about libyears. evilmartians.com/chronicles/r...

Great finding, by the way! I'll definitely add that as a warning to the docs on configuration 🙌

You get to consult with an experienced full-stack developer. I get to consult with an experienced business person running a real product.

@nickyt.online recently introduced me to Inertia JS

We’re exploring using it in a Rails 8 project (hosted on MSFT wtf)

Is anyone using Rails + Inertia + Vite in production these days?

Endorsements or horror stories?

Friends, we are publishing the new #Rails frontend story–for every small team that dreams big! The key to productivity is to use the full toolkit: Hotwire only, Hotwire with mounted React/Vue/Svelte components, and SPA with Inertia.js–while keeping it the Rails way.
