Day 42 of #100DaysOfCode — Schema Validation

In modern web development, APIs facilitate communication between clients and servers, but not all incoming data is reliable. Schemas define the structure and rules for data, allowing developers to specify required fields and constraints. Schema validation ensures that data adheres to these rules, preventing errors and security vulnerabilities. Without validation, even minor input mistakes can lead to significant issues, making it essential for building reliable and secure applications. For day 42, the goal was to understand why the validation of the schema is necessary and how it is done. What Is a Schema? A schema defines the structure of valid data . Think of it as a blueprint for your API requests. Example: User Schema Concept User ├─ name → string (required) ├─ email → valid email ├─ password → min length 6 └─ age → number ≥ 18 Rule: If the incoming request does not match the schema → reject it immediately . 🤔 Why is the schema needed?
