An Elixir library for generating struct constructors that handle external data with ease.
ExConstructor is an Elixir library that generates struct constructors to seamlessly instantiate structs from external data, such as JSON. It solves the problem of handling inconsistent data formats—like map vs. keyword list, string vs. atom keys, and camelCase vs. snake_case—automatically, reducing boilerplate code.
Elixir developers working with external APIs, JSON data, or any external data sources that require clean struct instantiation.
Developers choose ExConstructor for its simplicity and automation in handling common data format issues, which DRYs up code and accelerates development by letting them focus on business logic rather than data transformation.

Handles common data inconsistencies like string vs. atom keys and camelCase to snake_case automatically, as demonstrated in the example where mixed key formats are unified into a struct.
Inject a constructor function with a single `use ExConstructor` statement, eliminating boilerplate code for struct instantiation and adhering to Elixir's philosophy of clear, maintainable software.
Streamlines struct creation from varied external formats such as JSON API responses, making it ideal for applications integrating with third-party data sources.
Provides full documentation on Hexdocs with build status and coverage badges, indicating active maintenance and reliability for developers.
Focuses only on key format handling and doesn't support nested struct instantiation, data validation, or custom transformations, which may require additional libraries.
Relies on Elixir macros for code generation, which can introduce magic behavior that's harder to debug and adds slight runtime overhead compared to manual implementations.
Lacks features for data type checking or business rule enforcement, forcing developers to implement validation separately, as noted in the philosophy of focusing only on format inconsistencies.
