A high-performance GraphQL execution engine that uses Just-In-Time (JIT) compilation to significantly speed up query processing.
GraphQL-JIT is a high-performance GraphQL execution engine that uses Just-In-Time (JIT) compilation to optimize query processing. It compiles GraphQL queries into efficient JavaScript functions, leveraging V8 optimizations to deliver significantly faster execution speeds compared to standard GraphQL-JS, addressing performance bottlenecks in GraphQL servers.
Developers building GraphQL servers in Node.js who need improved query performance, especially for applications with complex resolvers or high query volumes.
It offers dramatically faster query execution (as shown in benchmarks) by compiling queries ahead of time, making it a compelling alternative to GraphQL-JS for performance-sensitive applications while maintaining broad spec compliance.
GraphQL execution using a JIT compiler

Shows up to 10x faster execution for queries with many resolvers in benchmarks, such as 339,223 ops/sec vs 26,620 for graphql-js in the fewResolvers test.
Compiles GraphQL queries into V8-optimized JavaScript functions, reducing interpretation overhead and leveraging native optimizations for speed.
Includes compiled subscription functions, enabling efficient real-time GraphQL operations with performance similar to queries.
Allows integration with fast-json-stringify via compilerOptions.customJSONSerializer, enhancing JSON output performance beyond standard JSON.stringify.
Targets only the June 2018 GraphQL spec, potentially missing newer features and updates, which limits compatibility with modern GraphQL tooling.
Requires explicit resolvers for all computed properties, as noted in the differences to graphql-js, restricting schemas that rely on default resolvers.
Adds an extra step to compile queries before execution, increasing setup complexity and error handling compared to drop-in graphql-js usage.
