PostGraphile
PostGraphile is an open-source tool that automatically generates a GraphQL API from a PostgreSQL database schema. It uses PostgreSQL's introspection capabilities to create a GraphQL schema that reflects the database structure, including tables, views, functions, and relationships. This allows developers to quickly build a GraphQL backend without manually writing resolvers or schema definitions.
Developers should use PostGraphile when they need to rapidly prototype or build a GraphQL API for a PostgreSQL-based application, as it reduces boilerplate code and ensures the API stays in sync with the database. It is particularly useful for projects where the database schema is the primary source of truth, such as in data-intensive applications or when leveraging PostgreSQL's advanced features like row-level security and stored procedures. It also simplifies API development by providing real-time subscriptions and performance optimizations out-of-the-box.
