OCaml GADTs for Authentication Tokens
In this article, I will present and explain a real-world usage of Generalized Algebraic Data Types (GADTs). GADTs will be used for safely parsing complicated objects with a schema, for example, authentication tokens like JWTs. This approach ensures type safety and robustness when dealing with complex token schemas, making your libraries more reliable and less error-prone. Before reading it, please make sure that you are familiar with GADTs as here I explain specific use case, but not GADTs themselves. In this article, I will focus on JWT, but the technique is applicable to any format. Authentication tokens
