In parts one and two of this series, we only dealt with the pure CRUD aspects of using SQLite as a production database. In this post, we will explore the world of queue mechanisms, using SQLite as the pub/sub adapter for ActiveJob. Let's make use of LiteJob to handle incoming webhooks in our Rails application.
Most websites are built with high-level languages like Ruby. Developers can always optimize their code for improved performance. Yet, even with top-notch optimization practices, what if your website still lags? How could WASM help improve the performance (time and speed) of your Ruby apps? Web Assembly is a technology that allows developers to compile code written in languages other than Javascript and run it on the web browser.
Ruby is an expressive language. This is no accident; Matz very consciously designed Ruby as an intuitive language to more or less read like English. It's safe to say that he succeeded. Methods are named very carefully, and do what they say they do; they also tend to have inverse methods which do the opposite. In this post, we'll look at why expressive code is important and its impact on your productivity as a developer. Then, we'll explore how to best use some of Ruby's methods. Let's get started!
Exceptions are a commonly used feature in the Ruby programming language. The Ruby standard library defines about 30 different subclasses of exceptions, some of which have their own subclasses. The exception mechanism in Ruby is very powerful but often misused. This article will discuss the use of exceptions and show some examples of how to deal with them.
Good code has a lot to do with how readable it is. As developers, we more often read code than write it. As my Perl teacher told us many times: the flexibility of Perl's syntax was its best and worst trait at the same time. Ruby's syntax was influenced partly by Perl and is also quite flexible. Whatever language you pick, set some guidelines to avoid overusing a language's flexibility. Style guides for Ruby abound on the web, and it's not difficult to pick a style nowadays.
If a web application involves users, as a matter of course, their data should be protected and secured. Securing a web application can mean several things. In this post, we'll discuss a subset of web security that involves authentication using JSON Web Tokens (JWTs) and the Ruby on Rails web application framework. Let's get started!
Ruby, the all-time popular programming language from Japan, has continued to evolve with each iteration, empowering developers worldwide to build powerful and elegant applications. As the community eagerly awaits the release of Ruby 3.3, there is a lot of excitement around the potential enhancements and features that this version promises to bring.
You've heard of metaprogramming: code you write that generates other code dynamically. Without it, Rails as we know it wouldn't (and couldn't) exist. But there's a good chance you've never done it yourself, and it's not hard to see why; even a brief excursion into the realm of metaprogramming can leave you beset with strange and foreign methods, unfamiliar syntax, and downright mystifying blocks of code.
