ROM + Dry Showcase: Part 1
The rom-rb and dry-rb sets of gems have come out in the last couple of years. These gems allow an alternative take on building a Ruby application, separate from Rails or Sinatra, or anything else like that.
In this series of blog posts, you will see how to build a simple application that called "Bix" using some of these gems. By the end of this series, the application will:

  • Part 1 - Interact with a database using ROM
  • Part 2 - Have validation and transaction classes
  • Part 3 - Test our application with RSpec
  • Part 4 - Have a router and a series of actions

Protecting Your GraphQL API From Security Vulnerabilities
GraphQL is quickly becoming the tool of choice for developers that need to build an API for their client application. But like all new technologies, GraphQL comes with its own threat landscape. Whether you’re building a side project or a large-scale enterprise application, you’ll need to make sure you’re protecting yourself against these GraphQL security vulnerabilities.

If you are developing a small app, kicking off a startup or just playing with Rails you can use cheaper solutions - cloud hosting, like DigitalOcean or Upcloud. The problem is the setup - you need to install dependencies on your own. Then deploy your application manually or using, for example, Capistrano, which also requires a lot of setup. What if we had self-hosted Heroku?

What kinds of Rails tests I write and what kinds I don’t
There are a lot of different kinds of tests a developer could possibly write. In RSpec there are model specs, feature specs, view specs, helper specs, routing specs, controller specs, and request specs. Do you need to write all these different types of tests? If not, which ones should you skip?
