🔗 Consolidating input and output validation and sanitization in Elixir with GuardedStruct library

Data integrity at the initial input stage is rarely straightforward, especially when diverse business logic requirements burden developers. Over time, this can lead to chaos in managing data structures. Another challenge lies in the libraries and tools available for handling these needs. To make them comprehensible and cover more complex requirements, they often resort to macros, which come with their own set of advantages and drawbacks—factors that may influence developers' preferences.

A prime example of such an infrastructure is the well-known Elixir library, Ecto. It demonstrates how to create a pipeline that processes input data from the start, cleanses it, and delivers a reliable output. This cleaned data can then be confidently stored in a database or displayed on a website.

The GuardedStruct library follows a similar path. It offers features such as builders, validation, and sanitization, enabling you to clean your data at the infrastructure level based on your business logic. Once processed, the data can be utilized across your application. Notably, during its development, the focus was on making it accessible even to project managers with limited Elixir knowledge. This ensures they can quickly build an MVP for their desired functionality with minimal learning curve.
