Description

Update PlanDetailsProps to reflect that either planId or plan is allowed.

To support similar cases in the future, I've added a new Typescript utility type called FlattenUnionType that accepts an union type of objects. All the shared properties are kept intact, the different properties are added to the output type as optional and undefined.

Example

type A = { a: number; c: number };
type B = { b: string; c: number };
type Result = FlattenUnionType<A | B>;
// Result: { a?: number; b?: string; c: number }

📝 Walkthrough

Walkthrough

This change updates the PlanDetailsProps type in multiple packages (@clerk/clerk-js, @clerk/types, @clerk/nextjs, and @clerk/clerk-react) to enforce that exactly one of either planId (string) or plan (CommercePlanResource) must be provided, using mutually exclusive union types. The __internal_PlanDetailsProps and __experimental_PlanDetailsButtonProps types were modified accordingly. The PlanDetailsButton component now casts its props explicitly to the updated type. Additional minor changes include adding a forPayerType property to a mock plan in a test and applying a type assertion to a component in a lazy renderer. No public API signatures were changed beyond the stricter typing.

packages/clerk-js/src/ui/components/Plans/PlanDetails.tsx (1)

32-38: Flattening the union type removes the “plan or planId” compile-time guarantee

FlattenUnionType<__internal_PlanDetailsProps> converts the mutually-exclusive union into an object where both planId and plan become optional.
As a result, external callers of PlanDetails can now omit both keys without a
type-error – exactly the opposite of the “stricter props” objective of this PR.

-export const PlanDetails = (props: FlattenUnionType<__internal_PlanDetailsProps>) => {
+// Keep the public surface strict …
+export const PlanDetails = (props: __internal_PlanDetailsProps) => {
+  // …and only flatten internally if you really need to.
+  const internalProps = props as FlattenUnionType<__internal_PlanDetailsProps>;
+  return (
+    <Drawer.Content>
+      <PlanDetailsInternal {...internalProps} />
+    </Drawer.Content>
+  );
+}

This preserves the mutual-exclusion contract for consumers while still letting the
implementation work with a flattened shape.

packages/clerk-js/src/ui/Components.tsx (2)

111-120: openDrawer('planDetails', …) no longer enforces that either planId or plan is provided

By switching to FlattenUnionType<__internal_PlanDetailsProps> the same
compile-time guard discussed earlier is lost for every caller of openDrawer.

Restore the original union to keep the API self-documenting and type-safe:

-    props: T extends 'checkout'
-      ? __internal_CheckoutProps
-      : T extends 'planDetails'
-        ? FlattenUnionType<__internal_PlanDetailsProps>
+    props: T extends 'checkout'
+      ? __internal_CheckoutProps
+      : T extends 'planDetails'
+        ? __internal_PlanDetailsProps

158-166: Revert planDetailsDrawer props to the strict union or add a runtime guard

The use of FlattenUnionType<__internal_PlanDetailsProps> turns both planId and plan into optional keys, allowing {} as valid props. This means you can open the drawer with neither identifier, leading to an unrenderable state. You should either:
• Revert the state slice to use the original union type so TypeScript enforces at least one key at compile time
• Or add a runtime check in componentsControls.openDrawer('planDetails', …) to ensure exactly one of planId or plan is provided

Locations to update:

  • packages/clerk-js/src/ui/Components.tsx (ComponentsState interface, around line 162)
  • componentsControls.openDrawer implementation (around line 379)

Suggested diff for the state slice:

   planDetailsDrawer: {
     open: false;
-    props: null | FlattenUnionType<__internal_PlanDetailsProps>;
+    props: null | __internal_PlanDetailsProps;
   };

And, if you opt for runtime validation, wrap calls to:

componentsControls.openDrawer('planDetails', props);

with a check such as:

if (!('planId' in props) === !('plan' in props)) {
  throw new Error('Must provide exactly one of planId or plan');
}
componentsControls.openDrawer('planDetails', props);

🔇 Additional comments (10)
packages/types/src/utils.ts (4)

117-119: LGTM! Standard TypeScript utility pattern.

The UnionToIntersection type implementation correctly uses the contravariant position pattern to convert union types to intersection types, which is a well-established TypeScript technique.


121-129: Excellent recursive type implementation.

The FlattenUnionTypeInternal type correctly handles the complex logic of flattening union types:

  • Preserves arrays as-is (line 123-124)
  • Recursively processes nested objects (line 126)
  • Properly marks properties as potentially undefined when they don't exist in all union members (line 128)

132-136: Perfect undefined-to-optional conversion logic.

The UndefinedToOptional type correctly separates properties into optional and required based on whether they include undefined in their type, and properly excludes undefined from the optional property types.


138-147: Excellent documentation and implementation.

The JSDoc documentation is comprehensive and the example clearly demonstrates the utility type's behavior. The final export properly chains together all the helper types to achieve the desired flattening behavior.

packages/types/src/clerk.ts (2)

1889-1904: Excellent type safety improvement.

The conversion to a union type properly enforces that either planId or plan must be provided, eliminating the ambiguous state where neither is specified. The intersection with additional optional properties maintains backward compatibility.


1916-1933: Consistent type design across experimental API.

The __experimental_PlanDetailsButtonProps follows the same union type pattern as __internal_PlanDetailsProps, ensuring consistency in the API design while maintaining the same type safety benefits.

.changeset/shaky-sloths-unite.md (1)

1-9: Appropriate changeset documentation.

The changeset correctly identifies this as a minor version bump across all affected packages and accurately describes the core change to PlanDetailsProps type constraints.

packages/clerk-js/src/ui/lazyModules/MountedPlanDetailDrawer.tsx (2)

2-2: Clean import addition.

The addition of FlattenUnionType to the existing import is necessary for the type update and maintains good import organization.


16-16: Correct adaptation to union type structure.

Using FlattenUnionType<__internal_PlanDetailsProps> properly handles the new union type structure, ensuring all properties are accessible with appropriate optionality while maintaining the null possibility for closed drawer state.

packages/clerk-js/src/ui/components/Plans/PlanDetails.tsx (1)

73-89: Avoid @ts-expect-error – pass a non-nullable id to getPlan safely

clerk.billing.getPlan expects { id: string }, but the current code suppresses
type-checking and may still attempt an undefined id if both props are empty
(contradiction introduced by the flattening above).

-() => clerk.billing.getPlan({ id: planId || initialPlan?.id }),
+() => clerk.billing.getPlan({ id: (planId ?? initialPlan!.id) }),

• The non-null assertion is safe because this fetcher is only executed when the
SWR key is truthy (planId || initialPlan?.id).
• Removing the @ts-expect-error retains full type safety.

1-1: Use type-only import for FlattenUnionType.

Since FlattenUnionType is only used for type casting and not at runtime, it should be imported as a type-only import for better tree-shaking.

-import type { __experimental_PlanDetailsButtonProps, FlattenUnionType } from '@clerk/types';
+import type { __experimental_PlanDetailsButtonProps, type FlattenUnionType } from '@clerk/types';

38-39: Type casting approach is sound but consider runtime validation.

The explicit casting to FlattenUnionType<__experimental_PlanDetailsButtonProps> correctly handles the union type constraint, allowing for easier property access. This aligns well with the PR's objective to enforce stricter prop requirements.

However, since TypeScript's type system is erased at runtime, consider adding runtime validation to ensure either planId or plan is provided, especially given this is an experimental API.

Consider adding runtime validation:

const { plan, planId, initialPlanPeriod, planDetailsProps, ...rest } =
  props as FlattenUnionType<__experimental_PlanDetailsButtonProps>;

if (!plan && !planId) {
  throw new Error('PlanDetailsButton: Either planId or plan must be provided');
}

36-68: Add tests to cover the stricter type constraints.

Since this PR introduces stricter type requirements and uses type casting, tests should be added to ensure the component works correctly with both planId and plan properties, and that the union type constraint is properly enforced.

Consider adding tests for:

  • Component renders correctly with planId provided
  • Component renders correctly with plan object provided
  • Component behavior when neither is provided (should ideally throw/fail gracefully)
  • Click handler calls the correct internal API with proper parameters

Would you like me to generate test cases for these scenarios?
