The quietly growing number of serious Haxe projects have something new to contend with: the first major compiler release in over three years. What does Haxe 4 bring to the table?

Micro-frontend architectures decompose a front-end app into individual, semi-independent "microapps" working loosely together. This can help make large projects more manageable, e.g. when transitioning from legacy codebases.

Nearly every app requires an authorization system on top of an authentication system. We often need a fine-grained permissions model to allow only specific users to access certain resources while simultaneously restricting access for everyone else. In this tutorial, Toptal Freelance Firebase Developer Joaquin Cid teaches how to build just such a system. Called role-based authentication, we'll learn how to implement this system in an API using Node.js and Firebase.

In the past few years, we've seen the introduction of a lot of new technologies in JavaScript, but we needed time to see how the market was going to adopt them. In this article, Toptal Freelance JavaScript Developer Alejandro Hernandez takes a look at how popular JavaScript is becoming and the factors that may have affected this popularity, and he tries to predict what the future of JavaScript will look like.

Types and testable code are two of the most effective ways of avoiding bugs. In this tutorial, discover TypeScript best practices while you create a Discord bot from scratch.

GraphQL is a query language for APIs, originally developed by Facebook for internal use. Since its public release, GraphQL has been compared to REST and other architectures. In this article, Toptal JavaScript Developer Marcos Henrique da Silva demonstrates how to create a GraphQL Node.js API, and explains why you should try it, too.

Static websites are simple and fast, but it's also possible to automate updates to them to keep them fresh and relevant. Find out how to generate daily-updated HTML pages that track the latest releases of popular GitHub repositories.

You can just write sequentially executed code in JavaScript, but should you? In this article, Toptal Freelance JavaScript Developer Omar Waleed tests the widespread Node.js belief that synchronous code degrades performance and is, in a sense, just plain evil. Is this really true?

Bulletproof data validation is fundamental to implementing a back-end API. Find out how datalize, a Node.js library, makes this easy—and formats your data nicely, too.
