GraphQL Zeus is a TypeScript-first GraphQL client generator that produces a fully type-safe query builder from any GraphQL schema. It provides a CLI tool (`zeus`) that accepts a GraphQL schema file or introspection URL and generates a complete TypeScript client with zero runtime dependencies beyond `cross-fetch` and `ws` (for subscriptions). The generated client supports multiple transport modes: standard HTTP via `Chain` and `Thunder` (with custom fetch injection), WebSocket subscriptions (both legacy and `graphql-ws`), and Server-Sent Events (SSE). It also offers integration helpers for Apollo Client (`typedDocumentNode`) and exports reusable selection set composition via `Selector`. The monorepo is structured into three packages: `graphql-zeus` (CLI orchestration), `graphql-zeus-core` (code generation engine and runtime functions), and `graphql-zeus-jsonschema` (JSON Schema generation from input types). The code generation pipeline parses the schema into a tree structure, then templates it into TypeScript types and runtime functions. The project is moderately well-maintained with active issues and a test suite focused on the core code generator, though the CLI lacks automated tests and the build tooling relies on the deprecated `ttypescript` package, indicating some technical drift.
