Data structure and type validations are so essential in modern Rails apps. You've probably used Active Model validations and strong parameters, but did you know there is a better way? This article introduces the dry-schema gem—a faster alternative to the defaults!

In Golang, wrapping errors means adding more contextual information to the error which has been returned. For example, the additional information could be the type of error, the cause of the error, or the name of the function where the error is raised. Wrapping is very useful for debugging since you can precisely and quickly locate the source of the problem.

The PHP PDOException is a runtime exception that occurs when something goes wrong while using the PDO (PHP Data Objects) class or its related extensions. For example, this exception can occur while handling database connections or queries.

Developers can develop agile applications using these conventions and write less code. Moreover, Ruby on Rails developers' communities can be enhanced in terms of maintainability and understandability. Furthermore, the developers use the Rails conventions and sensitive defaults in their web applications, making them more scalable. Among them are email management, object-database mappings, file structures, code generation, element naming and organization, etc.

Tables are an essential part of front-end development. Be it creating structured data or making data visualization easier for users including tables is almost essential. However, if you’re working with React often creating complex tables might provide you with insufferable stress as the process is quite complex and time-consuming. Hence, instead of using only React to create tables the use of external libraries for table creation is often encouraged for react-developers.

Since October is cybersecurity awareness month, it’s a great time to revisit the question of what are the best ways to secure user authentication in CIAM. In many industries (finance and healthcare, to name a few), regulations require the use of multifactor authentication (MFA) to protect access to sensitive data and transactions.

Javascript is the basis of today’s modern web technology and plays a pivotal role in providing effective functionalities to websites and web applications. One of the essential elements that power its capability to include complex functionalities is objects in Javascript. From performing as a holy grail that aids developers in creating complex data structures to storing multiple properties an object in JS can serve multiple purposes at once.

Compilers, transpilers, oh my! Learn how Babel and friends do their thing—which is the right for your JavaScript build environment?

If you're looking to add some spice to your web designs, you may be considering adding animation. SVG animation with CSS can be used to create rich, interactive experiences on the web. SVG is a vector graphic format that can be scaled to any size without losing quality. CSS is a style sheet language that can be used to style HTML elements. Combined, these two technologies can be used to create animations that are responsive, fluid, and resolution-independent.

Linting refers to the process of identifying potential errors in code by using a program. Initially, the lint tool, like earlier similar utilities, analyzed source code to determine which compiler optimizations could be made. In time, lint-like tools added many other types of checks and verifications. The Linting software provides developers with tools to help them write highly scalable code.
