Input Validation
Input validation helps us keep our applications safe and sound. It’s all about checking if the data users provide is in the right format and makes sense, so our system can work smoothly and securely. A popular way to do this is by using Regular Expressions (RegEx), which are advanced expressions that match specific patterns, such as email addresses or phone numbers.
This section will explore the ins and outs of input validation, from understanding its significance to learning various techniques and tools, including the omnipotent RegEx. We’ll dive into both client-side and server-side validation methods and share best practices to ensure our applications stay performant & secure. Additionally, we’ll look at some real-life examples of input validation issues and how to fix them.
