Generator reference
Generate TypeScript models and decorator clients from an OpenAPI document, with optional Wow CQRS discovery. The only root symbols are CodeGenerator and DEFAULT_CONFIG_PATH.
Install
pnpm add -D @ahoo-wang/fetcher-generator @ahoo-wang/fetcher @ahoo-wang/fetcher-eventstream @ahoo-wang/fetcher-decorator @ahoo-wang/fetcher-openapi @ahoo-wang/fetcher-wow typescriptVersion 5.0.0 itself declares Node >=18.20.8, but its CLI dependency commander 14 requires Node >=20. Use Node >=20.20.2 for this toolchain; repository development additionally pins pnpm 10.34.5. The command includes all recursive peers (Generator → Wow/Decorator/EventStream/OpenAPI → Fetcher) and the compiler used below. ts-morph, commander and yaml install automatically as regular dependencies. These are generation-time dependencies; generated clients need their imported packages installed as runtime dependencies in the consuming application, as listed under generated output.
Minimal example
pnpm exec fetcher-generator generate -i ./openapi.json -o ./src/generated -t ./tsconfig.jsonChoose an entry point
Use the CLI for a reproducible build step and CodeGenerator.generate() for a Node script with a custom logger. Both produce source files; neither executes API operations. Start with the complete CLI input and tsconfig, then check output ownership before regenerating.
