Field arguments vs. directives in GraphQL

The text explores the functionalities and differences between field arguments and query-type directives in GraphQL, explaining how both can be used to modify field output. Field arguments are versatile, allowing both data retrieval and functionality application, while directives are limited to functionality. Arguments are preferred for compatibility with the GraphQL spec and to avoid potential conflicts with clients and tools, as directives can be inconsistently supported and may cause issues with caching. However, directives offer benefits in terms of modularity, code reusability, and schema design, and can be more efficient for certain operations, such as making batch API calls. While directives provide valuable functionality, they exist in a gray area within the GraphQL specification, leading to recommendations to use field arguments unless the directives' use is well-understood and controlled.
