In this article, we'll introduce Ruby on Rails' lesser-known but powerful cousin Sinatra. We'll use the framework to build a cost-of-living calculator app. By the end of the article, you'll know what Sinatra is and how to use it. Let's go!
This article will teach you how to monitor Ruby errors without using a service like Honeybadger! Learn about Ruby's built-in errors, how to use log levels and tagging to customize the log output, display errors on the front-end, and more.
Logs are essential to any application's development. Most Ruby logs are verbose and chunky, so digging for exactly what you need can be difficult. Even though they contain useful information, you might not get as much value as you should from logs if you don't know how to use them effectively. In this article, we'll explore: Let's get started.
Working with invoices, contracts, or just reading your favorite mystery thriller—whatever the case, PDF files are everywhere. Learn how to work with PDFs in Ruby.
There are many ways to load code and access file-related constants in Ruby. We can create a clear architecture by separating and handling concerns into classes and pulling in only the classes we depend on. Many full-stack frameworks like Rails and Hanami offer a built-in method to access the classes we want, as long as we stick with a certain convention. How does this work? In this post, we will explore three different options for loading code: using load, require, and autoload.
Setting up authentication for your Ruby app is important to ensure it is secure. In this post, we'll explore the rodauth-omniauth gem for Ruby to implement authentication in your app via third-party providers. First, let's quickly define authentication before exploring the benefits of OmniAuth and setting up the rodauth-omniauth gem for a Rails app. Let's dive straight in!
Lambdas are a powerful feature of the Ruby language. They allow you to wrap logic and data into a portable package. In this post, we’ll cover how and when to use lambdas. You'll also learn about the difference between lambdas and Procs, and the performance profile of lambda functions. The code examples have been tested with 2.6 and 2.7 and should work with most modern Rubys. Use the links below to skip ahead in the tutorial.
Customizing exceptions is usually not a common concern during software development. But if you catch an error in an observability tool and can't correctly and quickly identify the problem, you may need more information and details about an exception. This article will show you how to customize exceptions in Ruby and mitigate potential future problems due to a lack of error information. Let's dive straight in!
Today, many web applications will feature pages that are publicly available — like a homepage — and more secure ones where a user has to log in to get access. The process of user registration, logging in, and tracking user session state is called "authentication". At the same time, when dealing with logged-in users, it's necessary to separate actions and resources that are available to them depending on their user roles. For example, "admins" generally have more access than normal users.
This article explores how to use markdown in Ruby. Learn how to use two popular Ruby libraries—Redcarpet and Kramdown—to parse markdown and create a simple documentation app using Redcarpet and Sinatra.
