Schema First

Schema First is an approach in software development, especially with GraphQL, where the structure of the data and how clients can interact with it is designed and agreed upon upfront. Think of it like creating a detailed blueprint or map before building a house. This schema defines what data exists, how it’s organized, and what operations are possible. Developers then build the backend system to match this blueprint. This method helps ensure clear communication between teams, consistent data handling, and easier maintenance by having a well-defined plan before implementation begins.
