Support for recursive types #459
Description
For now trpc-openapi does not support recursive types because of this: https://github.com/jlalmes/trpc-openapi/blob/master/src/generator/schema.ts#L19
But now zod-to-json-schema fixed that so we can delete refStrategy: "none".
Repro:
import { initTRPC } from "@trpc/server"; import type { OpenApiMeta } from "trpc-openapi"; import { generateOpenApiDocument } from "trpc-openapi"; import { z } from "zod"; import { zodToJsonSchema } from "zod-to-json-schema"; const baseCategorySchema = z.object({ name: z.string(), }); type Category = z.infer<typeof baseCategorySchema> & { subcategories: Category[]; }; const categorySchema: z.ZodType<Category> = baseCategorySchema.extend({ subcategories: z.lazy(() => categorySchema.array()), }); // here zod-to-json-schema handles circular reference console.dir(zodToJsonSchema(categorySchema), { depth: null, }); const t = initTRPC.meta<OpenApiMeta>().create(); const appRouter = t.router({ sayHello: t.procedure .meta({ openapi: { method: "POST", path: "/say-hello" } }) .input(categorySchema) .output(z.object({ greeting: z.string() })) .mutation(({ input }) => ({ greeting: `Hello ${input.name}!` })), }); export const openApiDocument = generateOpenApiDocument(appRouter, { title: "tRPC OpenAPI", version: "1.0.0", baseUrl: "http://localhost:3000", }); // circular reference is not handled correctly, Defaults to any console.dir(openApiDocument, { depth: null });
