Datacaster

This gem provides DSL for describing in a composable manner and performing run-time type checks and transformations of composite data structures (i.e. hashes/arrays of literals). Inspired by several concepts of functional programming such as monads.

Detailed error-reporting (with full i18n support) is one of a distinct features. Let your API consumer know precisely which fields and in a what manner are wrong in a deeply nested structure!

It is currently used in production in several projects (mainly as request parameter validator).

DHH about Kamal

What I love about Kamal is how it gives plain cloud hosts like Hetzner the deployment ergonomics of something like Heroku but at a sliver of the cost. Look at these instance prices! 💻kamal-deploy.org

👩‍💻 Using esbuild and Bootstrap in a Rails 7 Project by Replacing the Default Importmap

In this article, we will explore how to integrate es build and Bootstrap into a Rails 7 project by replacing the default importmap. Rails 7 comes with a default bundle import map, but we can still leverage the power of esbuild for efficient CSS and JavaScript bundling. By doing so, we can take advantage of esbuild’s lightning-fast bundling capabilities and enhance our application’s performance.

👩‍💻 7 new tools introduced in DHH's Rails World keynote

Here is a brief overview of the tools announced by DHH during the keynote of Rails World 2023:

Propshaft, Turbo 8, Strada, Solid Cache, Solid Queue, Mission Control, and Kamal.

- Propshaft: Best bundling is no bundling, see all of Hey's frontend code in your browser.

- Turbo 8: Turbo morphing will keep your old state and scroll position intact enabling smooth transitions. View Transitions only supported in Chrome, but worth investment already for the bright future. No more TypeScript.

- Strada: Last piece of Hotwire driving native controls in mobile applications.

- Solid Cache: Redis is great, but we don't need it anymore as it's 5-10x pricier than disk. An affordable way to keep data around for much longer (months vs days). Cache trimming + Encryption + Sharding.

- Solid Queue: Replace 6 queue gems with one (from Resque) and drop Redis completely. GoodJob as inspiration, MySQL needed.

- Mission Control: A new dashboard for ActiveJob originally built for Resque after an outage at Basecamp.

- Kamal: Enable 37signals to sell self-hosted software. Deploy your Rails app (and even non-rails one) with zero downtime.

Some ViewComponent tips

If you're reading this, you know about View Components. Odds are that like me, you love them! You've probably also heard of Phlex, but decided to favour ViewComponents. You might even be keeping up with recent Rails improvements, like allowing templates to define which locals they accept.

If you use ViewComponents in your Ruby on Rails apps, read this article.
