In this tutorial, you will learn how to add TypeScript support to Node.js projects. Let's get going!

A while back, you were probably looking for a great solution to create your blog, and Gatsby was the most popular solution floating around at the time. Now that some time has passed, a new player has risen to fame on the scene: Next.js has taken developer blogs by storm. Whatever your reasons for switching, we will explain how to switch from the Gatsby stack over to Next.js in this post.

LiveView empowers developers to build interactive, single-page web apps with ease by providing a framework that eliminates the need for guesswork. In this post, we'll take a look at how you can layer simple, single-purpose functional components to wrap up shared presentation logic. We'll also use more sophisticated live components to craft easy-to-maintain single-page flows that handle complex user interactions.

Flaky tests are like meme stocks — many people have them, but no one knows what to do with them. Today, we will change that by diving into some common causes and, more importantly, solutions for flickering tests in Elixir. Elixir has many great primitives that let us run tests asynchronously, including immutable data, lightweight processes, and the Ecto SQL sandbox. Running tests asynchronously can greatly speed up your test suite, but can also increase the chance of flaky tests.

Rails 7 is just around the corner. We don't have a confirmed release date, but it is expected to be available before Christmas, so not very long to go. The latest version as of this post's publication is 7.0.0.rc1, the first release candidate. Basecamp, HEY, Github, and Shopify have all been running the Rails 7 alpha in production, so we can expect even the release candidate to be pretty stable. In this post, we will look at some of the new features and changes that Rails 7 will bring.

On December 3rd, the Elixir core team announced the latest Elixir release, 1.13. In this post, we'll explore some of the more exciting changes and new features, and discuss their impact on the Elixir community.

In this post, we will explore memory heap allocation in Node and push local hardware to its limit. Then we will find practical ways to monitor Node processes to debug memory issues. Ready? Let’s get going! To follow along, you can clone the code from my GitHub.

Elixir provides a very powerful suite of tools that devs can use to observe the behavior of their code and debug errors. There are several different strategies you can use to debug code in Elixir. While it is hard to produce a comprehensive list of all possible debugging methods, we will cover some of the most common methods in today’s post.

Performance is one of the most important aspects of web application development. A fast application will make its users, developers, and business stakeholders happy, while a slow one is sure to frustrate all three parties. In this article, we will consider some practices that you should adopt to scale your Node.js servers. Your servers will then be able to handle high traffic workloads without a degraded user experience.

It is vital that you understand how garbage collection works in Ruby to stay in complete control of your app’s performance. In this post, we will dive into how to implement and customize garbage collection in Ruby. Let’s get going!
