One of the most interesting challenges I met during Hanami development is to write isolated integration tests. The framework ships with an extensive Command Line Interface (CLI) to generate (or destroy) code, start the server, open a Ruby (or a database) console, create/drop the database, run the migrations, precompile assets, and print informations. Console Hanami console is an interactive REPL b

Do you need a fast and lightweight JSON API app? It must be powerful, flexible, quick to develop and easy to deploy? There is a simple solution for all these requirements: to use Lotus gems to build it. Lotus is well known for full stack web applications (via lotusrb), but all the gems of this toolkit can be used as standalone components in existing Ruby applications. It this case we will compose

Last month I gave the closing keynote at RubyDay 2015 by talking about Lotus and the future of Ruby. For the attendees, the most surprising part of my speech was about MRuby. It’s a minimal version of Ruby, that can be embedded in any system that supports C. I think that this technology can play a key role for Ruby in the next years. The simplicity of the language can be used within complex system

Do you find Test Driven Development (TDD) good in theory but hard to practice? Do you think it requires too much discipline and you don’t have time? Or, are you just struggling to get your workflow streamlined? Fighting to glue your tools together? Well, you can improve a lot, by borrowing some tricks from me. I’ve practiced TDD with Ruby for many years now, and built an entire web framework only

A year and a half ago I felt frustrated by the state of the art of web development with Ruby. Secretly, in my spare time, I started hacking with new ideas, taking nothing for granted, destroying and starting from scratch several times, until the software was distilled in a beautiful API. It took me a decade to get here, by following a process of subtraction of what isn’t essential. Countless refin

Luca Guidi Family man, software architect, Open Source indie developer, speaker. Introduction Sidekiq is the standard in the Ruby ecosystem for background jobs. This short tutorial will show you how to set up Sidekiq in a Hanami application using Docker Compose. For the basic setup, please look at my previous tutorial: Getting Started with Hanami and Docker Compose. We’ll modify that demo applicat

A few years ago, my lead develop of the time, told me: “Beware of the coupling that you’re introducing in your models”. My answer was: “Hey, you don’t know what you’re talking about, this is ActiveRecord”. I was an unexperienced developer fascinated by the innovation that Rails introduced. After all, my technology was able to get rid of all that configurations, and all that boring stuff from the p
