A TypeScript library that compiles GraphQL queries into optimized JavaScript functions using V8's JIT compilation, serving as a drop-in alternative to graphql-js execution with significantly better performance. It supports the June 2018 GraphQL spec including queries, subscriptions, and resolvers, with some limitations around computed properties and Promise handling.

Use cases

• speed up GraphQL query execution in Node.js servers
• replace graphql-js execute for better throughput
• compile GraphQL documents into reusable functions
• run GraphQL subscriptions with lower overhead
• benchmark GraphQL execution performance
• serve high-traffic GraphQL APIs with lower latency

When to choose

• your GraphQL server is CPU-bound on query execution and graphql-js is a bottleneck
• you need many resolvers executed per query at high request rates
• you want a mostly drop-in replacement for graphql-js execution with the same schema tooling
• you can precompile queries at startup or cache compiled queries per document

When to avoid

• you rely on default field resolvers returning Promises for computed properties without explicit resolvers
• you need the very latest GraphQL spec features beyond June 2018
• your workload is dominated by I/O rather than execution overhead
• you depend on graphql-js internals or custom execution semantics that jit does not replicate
