openapi-zod-clientが整数型のenumをZod公式の方針通りに変換してくれなかったりしたので諸々直してもらった

- in: query
  name: foo
  schema:
    type: integer
    enum:
      - 1
      - 2

{
  name: "foo",
  type: "Query",
  schema: z.union([z.literal("1"), z.literal("2")]).int()
}

- in: query
  name: bar
  schema:
    type: number
    enum:
      - 1.234
      - 2.345

{
  name: "bar",
  type: "Query",
  schema: z.union([z.literal("1.234"), z.literal("2.345")])
}

targetString.replace(
  /(z.union\(\[(?:z\.literal\("-?[0-9]+\.?[0-9]*"\)(?:, )?){1,}\]\))(?:\.int\(\))?/g,
  (_m, p1) => p1.replaceAll('"', "")
)

if (schema.type === "integer" && !schema.enum) {
    validations.push("int()");
}

- in: query
  name: foo
  schema:
    type: integer
    enum:
      - 1
      - 2

{
  name: "foo",
  type: "Query",
  schema: z.union([z.literal("1"), z.literal("2")])
}

  if (schema.enum) {
      if (schema.type === "string") {
          // 略
      }

+   if (schema.type === "integer" || schema.type === "number") {
+       return code.assign(
+           `z.union([${schema.enum
+               // eslint-disable-next-line sonarjs/no-nested-template-literals
+               .map((value) => `z.literal(${value === null ? "null" : `${value}`})`)
+               .join(", ")}])`
+       );
+   }

      return code.assign(
          // 略
      );
  }

}

expect(getSchemaAsZodString({ type: "integer", enum: [1, 2, 3, null] })).toMatchInlineSnapshot();
expect(getSchemaAsZodString({ type: "number", enum: [1.2, 3.4, 56.789, null] })).toMatchInlineSnapshot();
