Data validation is essential to avoid unexpected behavior, prevent errors, and improve security. It can be performed both on a web page — where data is entered — and on the server, where the data is processed. In this tutorial, we'll explore data validation in the Node.js backend. Then, you'll learn how to implement it in Express using the express-validator library. Get ready to become a Node.js data validation expert!

Whether you’re an independent software vendor (ISV) or enterprise-sized company, you want the analytics software you invested in to enhance your users’ decision-making, open up greater access to key data, and improve operational performance for the long-term. However, continuously achieving these business outcomes requires a modern solution. Many organizations still rely on older business intelligence (BI) tools for reporting due to long-term licensing.

Ably LiveSync is a product we launched last month to help developers deliver live updates in their applications by automatically keeping their database and frontend clients in sync. LiveSync is made of two components, the Models SDK that runs on the client, and the database connector that listens to changes in your database and syncs those changes to your clients.

In the ever-evolving world of software development, a well-defined test plan is the cornerstone of a successful Quality Assurance (QA) process. For QA professionals, testers, testers, and developers alike, a robust plan ensures comprehensive testing, minimizes risks, and ultimately delivers high-quality software. Traditionally, spreadsheets like Excel have been the go-to tool for crafting test plans. However, as projects grow in complexity, the limitations of spreadsheets become increasingly apparent.

When building web applications in PHP, there may be times when you want to add metadata to annotate your code that can be read by other parts of your application. For example, if you've ever used PHPUnit to write tests for your PHP code, you'll have likely used the @test annotation to mark a method as a test in a DocBlock. Traditionally, annotations like this have been added to code using DocBlocks. However, as of PHP 8.0, you can use attributes instead to annotate your code in a more structured way.

PHPs compiler and bytecode cache OPcache not only cache the compile step from PHP source code to virtual machine bytecode, they also include optimizations that can produce faster bytecode: For example PHP can: For PHP 8.4 Tideways sponsored the work of our colleague Tim to add another compiler optimization for the function sprintf().
