@nyxapi/codegen

Schema parsers, the normalized API model and the deterministic TypeScript generators behind @nyxapi/cli. Reads OpenAPI 3.0/3.1, Swagger 2.0 (converted to OpenAPI 3 first) and GraphQL (SDL or introspection JSON). Use it directly in a build script:

import { generateFrom } from "@nyxapi/codegen";

const { files, diagnostics } = await generateFrom(schemaText, { validation: true });

generateFrom detects the schema kind (or honor config.kind) and is async because GraphQL support loads the graphql package on demand. The synchronous generate(text, config) handles OpenAPI/Swagger only. For GraphQL pass your own operations with generateFrom(sdl, config, { documents: [{ name, text }] }).

Both throw GenerationError with every problem found; warnings are returned. The config format is described by @nyxapi/codegen/config.schema.json. Generated REST code imports @nyxapi/core; generated GraphQL code imports @nyxapi/graphql.
