tailcall

Allows defining both GraphQL schema and resolvers in a single .graphql file using custom directives like @http, eliminating boilerplate code as shown in the JSONPlaceholder example.

Benchmarks demonstrate superior throughput in N+1 query scenarios, outperforming other GraphQL solutions, with detailed evidence from the graphql-benchmarks repository.

Easily combines data from multiple REST APIs into a unified GraphQL endpoint via directives, reducing the need for manual resolver implementation.

Supports caching through the @upstream directive to improve response times by minimizing redundant upstream calls, as indicated in the schema configuration.
