In this article, Toptal Freelance JavaScript Developer Nick Chikovani shows how easy it is to perform web scraping using a headless browser. Specifically, he provides a Puppeteer tutorial, going through a few examples of how to control Google Chrome to take screenshots and gather structured data.

Your software isn’t fully tested until you write integration tests for it. While unit tests help ensure that functions are properly written, integration tests help ensure that the system is working properly as a whole.

In this article, Toptal Software Engineer Luka Blažecki uses Node.js to explain why integration testing is important for every development platform and how to write clean, composable integration tests.

Camera systems are very important in conveying the right atmosphere in video games. When developing games, even 2D ones, advanced cameras should be your tool of choice.

In this article, Toptal engineer Mihai Cozma shows us how to build a modular camera system for 2D platform games using some simple components in Unity that can be easily extended to 2.5D or even 3D games.

Discord is a popular real-time messaging platform with robust support for programmable bots. Bots are ubiquitous on Discord and provide a wide range of services, including moderation assistance, games, music, internet searches, payment processing, and more.
