AI-generated code comments keep reminding me of WYSIWYG: What You See Is What You Get. If the comment only repeats what the next line of code already says, it’s not documentation — it’s a subtitle. 😅 The best comments explain why, not what.

TIL: Rendering multiple form_with forms on the same page can generate duplicate input IDs 😬 That led to a confusing Turbo behaviour: after an autosubmit, focus was restored to the first matching element, causing page jump to the top. Fix: add a namespace to generate unique IDs.

Tiny detail. Huge delight. Saw this from @jhey.dev and had to try it myself 🙂 Every pointer deserves a pointerdown.

Saw this beautiful toggle switch from jonkanter and couldn’t resist rebuilding it. CSS only. No JavaScript. Just a fun little challenge. ✨ codepen.io/elalemanyo/f...

Nice little Rails tip from @andycroll.bsky.social 👌 I learned that helpers like tag.*, link_to and form builders already process class: values, so you can pass arrays directly without wrapping them in class_names. Worth the read 👇 andycroll.com/ruby/use-cla...

Cardinal Directions Select UI using pure CSS 🧭 The user still gets a <select> for choosing N, S, E, W, etc. — but the compass gives animated visual feedback based on the selected option. No js. Just :has(), option:checked, SVG, and CSS transforms 👇 codepen.io/elalemanyo/p...

we used to have dreams... now we have 47 todo apps syncing tasks we’ll never do “save for later” is just procrastination with better UX

I built csspin-rails — like importmap-rails, but for CSS. Pin CSS packages from npm, vendor them into vendor/assets/stylesheets, and use them. No Node.js needed. Not sure if I’m the only one who needed this 😄 Feedback welcome 👇 github.com/elalemanyo/c...

CSS doesn't natively handle truncating text from the middle. Inspired by @wesbos.com , I built a Stimulus controller for it. Super useful for long URLs & filenames. Also using Cheng Lou pretext for smarter truncation 🙏 Super useful for long URLs & filenames 👇 github.com/elalemanyo/s...

Just read “The Too Early Breakpoint” by @ishadeed.com — and once again, super inspiring to read. Such a clear way of explaining a subtle responsive design problem, with practical takeaways you can apply immediately. Always a pleasure to read your posts 👏🙏 ishadeed.com/article/too-...

The Too Early Breakpoint

An opinion on why we shouldn't switch to the smallest design too early.

Needed a helper to find the next occurrence of a date (birthdays, holidays, etc.), so I built it. Now it’s an open @rubyonrails.org.web.brid.gy PR: Date.upcoming_date(month, day) 🎉 Proud to give back to the open-source community that gives us so much ❤️ Hope it gets merged 🤞 t.co/XD0hlDYenB

Inspired by @donnfelker.bsky.social’s Stimulus controllers for Lexxy, I built one that adds file type and size validation directly in the editor. Big thanks to @jorgemanru and the @basecamp team 🙌 Full write-up 👉 www.dotruby.com/articles/add...

Redesigning a Rails app? 🚀 We discovered an underrated feature: :variants. With just one magic suffix you can run old & new layouts in parallel — no JS, no cookies, just Rails ✨ Full write-up 👉 dotruby.com/articles/eas...

Easy Redesign in Rails: Run Old and New Side by Side with :variants

Rails variants are usually used to serve different views for devices — but you can use them for much more, like running a redesign side by side.

Discovered a neat trick in the turbo_power gem by @marcoroth.dev 💡 turbo_stream.toggle_css_class supports force:, just like the DOM API. No need for manual logic — may the force: be with you 🛸✨

HexaPDF gem from @gettalong.bsky.social made it super easy to add PDF form filling to our rails app 🙌 The hardest part? Finding the PDF form field names 🤯 We wanted to give back, so we built a tool to list them all: dotruby.com/tools/hexapd... Drag a PDF → see all field names → done ✅

🚨 Rails tip: Appending query params with concat or + "?..." can break your URLs — especially if the URL already includes parameters. Instead of risking invalid or double ?s, use a proper helper that merges params safely. 👇

💡 I needed to check if a string is a valid app path in my Rails app — surprisingly, couldn’t find a built-in way. So I wrote a small helper method. Sharing in case it helps someone — or if there’s a better way? 🤔👇

I remembered today and thought I'd share: You can use .many? instead of count > 1 — more readable and sometimes faster! 💡 On relations: uses LIMIT 2 ⚠️ On associations: loads all records

Anchor links not scrolling correctly in your Rails app? Turbo Drive intercepts clicks and replaces page content via fetch (not a full page reload) — and that breaks native #anchor scrolling. Fix it with data-turbo="false" Tamed the Turbo — anchor away! ⚓

Just discovered you can add an if after a content_tag block in Rails views — way cleaner than wrapping the whole thing! Always finding little gems in ERB 💎😍

Pluralizing model names in Rails with proper i18n — there's a helper for that. I wrote a small helper that uses model_name.human(count: ...) to do it the right way — fully i18n-ready. Simple, readable, and it works with any model as long as it's been translated 😉

💡 Clean Rails views with conditional wrapping? Use conditional_tag to wrap content in a tag only if a condition is true. No more messy if blocks in ERB. Just clean, readable templates. Discovered this gem thanks to @scarfacedeb 🙌

Nobody likes to pack — not IRL, not on GitHub. 🧳 So I built github-repo-manager: For when you're leaving a GitHub org and want to take all your repos without the manual drag-n-drop drama. One script. No cardboard boxes. 🐙💼 github.com/elalemanyo/g...
