Migration: @kubb/plugin-faker

Part of the v4 → v5 migration guide. See the full option reference in @kubb/plugin-faker.

dateType, integerType, unknownType, and emptySchemaType moved to adapterOas. See Migration: @kubb/adapter-oas. resolver.resolveName replaces the transformers.name callback. Every other option stays the same.

Generated output

Stricter return type and intermediate variable

The create prefix stays in v5 (createPet is still createPet), matching the naming plugin-msw uses. What changes is the return type and the internal structure.

- export function createPet(data?: Partial<Pet>): Pet {
-   return {
-     ...{
-       id: faker.number.int(),
-       ...
-     },
-     ...(data || {}),
-   }
- }
+ export function createPet(data?: Partial<Pet>): Required<Pet> {
+   const defaultFakeData = {
+     id: faker.number.int(),
+     ...
+   }
+   return {
+     ...defaultFakeData,
+     ...(data || {}),
+   } as Required<Pet>
+ }

Required<Pet> guarantees that callers see populated fields even when the schema marks them optional.
