Pagination means dividing a big chunk of data into smaller pages. It unlocks performance benefits for the backend, while also improving UX by sending manageable pieces of data to a client. In this article, we'll explore offset-based and cursor-based server-side pagination approaches, compare them, and implement cursor-based pagination in Node.js. Let's get started!

Ruby on Rails has changed how we build web applications. Early on, the framework came with some great features to help you get started and build robust applications. However, it can still be tricky to build and handle forms. Simple Form is a great option. Let's examine what Simple Form is, why we might need it, and some real use cases.

Kernighan & Pike, The Practice of Programming, 1999 Despite constantly changing technologies and the needs of customers, some wisdom seems eternal. Programmers need to test their code. But thorough testing takes time. When we do it well, everything works, and a massive testing effort feels like a waste. However, when we do it badly, our code is often broken, and we wish that we had done better testing. I have some good news for you.

For a software engineer, even the basic use of a debugger can save a lot of pain: adding breakpoints (places in the code the program will stop at and expose the current context) is very easy, and navigating from one breakpoint to another isn't difficult either. And with just that, you can say goodbye to a program's many puts and runs. Just add one or more breakpoints and run your program.

Node.js 22 has been released, offering a compelling upgrade for developers. It takes over the 'Current' release line, while v21 transitions into maintenance mode until its end-of-life in June. This release delivers advances like a stabilized Watch mode, pattern matching support in the fs module, a default-enabled WebSocket client, and a new--run flag for script execution. It also offers some performance improvements and the usual V8 engine upgrade.

Bun and Node.js are two JavaScript runtime technologies to run JavaScript on the server. Node.js is the undisputed king of server-side development with JavaScript, but Bun has gained popularity thanks to its unbelievable performance capabilities. The real question is, though: does it really make sense to use Bun instead of Node.js? Let's learn about Bun and Node.js, dig into their characteristics, and explore some scenarios where Bun can be a better alternative to Node.js.

In modern web applications, real-time communication has become more than a feature: it's gradually evolved into a necessity. Users expect instant updates, live interactions, and dynamic content. In Rails applications, Action Cable has long been the go-to solution, harnessing WebSockets to fulfill these demands. In this article, we introduce: Let's get started!
