GraphQL Helix HTTP Server Utilities

GraphQL Helix is a collection of framework and runtime agnostic utility functions designed for building GraphQL HTTP servers. It focuses on adherence to the GraphQL over HTTP specification, enabling a single HTTP endpoint for queries, mutations, subscriptions, and features like `@defer` and `@stream` directives. The package supports both server push and client pull paradigms for real-time data. It is known for its minimal footprint, having zero dependencies outside of `graphql-js` itself, and works across Node.js, Deno, and browser environments. The current stable version is 1.13.0, with minor and patch releases occurring frequently, as indicated by recent changes adding `extensions` and `operationName` to `ExecutionContext` and improving `accept` header handling. Its key differentiators include its agnosticism to specific HTTP frameworks and runtimes, strong HTTP-first and spec-compliant approach, and a focus on providing core abstractions without bloat or integrated platforms.
