Understanding JSON:API
The JSON:API specification is a standard designed to minimize both the number of requests and the amount of data transmitted between clients and servers. By providing a shared convention, it allows teams to focus on their application logic rather than the format of the HTTP requests and responses. Originally authored by Yehuda Katz and Dan Gebhardt, the specification has become a cornerstone for building efficient REST APIs.
A core feature of JSON:API is the concept of compound documents, which allows servers to send related resources in a single response using the included key. This reduces the "N+1 query problem" often found in traditional API designs. Furthermore, it supports Sparse Fieldsets, enabling clients to request only the specific attributes they need, further optimizing bandwidth usage.
Compliance with the specification requires adhering to specific media type requirements, specifically application/vnd.api+json. This ensures that clients and servers can communicate using a predictable structure for resources, relationships, and error handling.
