chore(repo): Upgrade to TypeScript 6.0 by dstaley · Pull Request #8177 · clerk/javascript

dstaley · 2026-03-27T17:27:06Z

Description

Updates the repository to TypeScript 6.0, and replaces usage of tsup with tsdown where it was necessary for the packages to build correctly. (There are a few remaining packages using tsup, but those don't break when built with TypeScript 6.0, so I'm saving them for a future PR.)

The majority of this PR was reviewed as individual PRs.

Checklist

📝 Walkthrough

Walkthrough

Bumped the pnpm-workspace.yaml TypeScript catalog pin catalogs.repo.typescript from 5.8.3 to 6.0.2. Removed four TypeScript interfaces related to serialized passkey native-module responses and removed two of those names from an import list while runtime references remain. Updated several tsconfig.json files (removed baseUrl, added types: ["node"] and/or rootDir: "./src"). Replaced multiple src/... path-alias imports with relative imports. Changed PEM helper and JWT verification code to use Uint8Array types. Switched several packages’ build tooling/configuration from tsup to tsdown and adjusted related configs and package scripts.

⚠️ Potential issue | 🟠 Major

Add migration coverage before merge.

This TypeScript 6 compiler-config change is not accompanied by test updates; please add/modify tests (at minimum package-level build/typecheck coverage for packages/expo-passkeys) to guard against upgrade regressions before merging.

As per coding guidelines, "If there are no tests added or modified as part of the PR, please suggest that tests be added to cover the changes."

🤖 AI review (reclassified as non-breaking) (92%): The before/after types are structurally identical — the change is purely a re-export alias rename (private chunk alias _clerk_shared__chunks_index_CE5uejGj.* replaced by public @clerk/shared named exports like UserResource, OrganizationResource, etc.); the resolved shapes are the same, so no well-typed consumer code is affected.

🤖 AI review (reclassified as non-breaking) (92%): The wrapped type changed only from an internal chunk alias (_clerk_shared__chunks_index_CE5uejGj.xo) to the public @clerk/shared.OrganizationResource; both resolve to the same structural type, so consumers reading the store value are unaffected.

Modified: `$userStore`

Modified: `hasValidSignature`

- hasValidSignature: (jwt: import("@clerk/shared/types").Jwt, key: string | JsonWebKey) => Promise<NonNullable<boolean | undefined>>
+ hasValidSignature: (jwt: Jwt, key: JsonWebKey | string) => Promise<boolean>

Static analyzer: Breaking change in function hasValidSignature: Return type changed: !Promise:interface<!NonNullable:type<boolean|undefined>> → !Promise:interface<boolean>; Parameter key type changed: string|!JsonWebKey:interface → !JsonWebKey:interface|string

🤖 AI review (reclassified as non-breaking) (95%): Both the parameter order change (string | JsonWebKey → JsonWebKey | string) and the return type narrowing (Promise<NonNullable<boolean | undefined>> → Promise<boolean>) are non-breaking: union member reordering is structurally identical, and NonNullable<boolean | undefined> resolves to boolean, making the return type change purely cosmetic.

Modified: `verifyJwt`

- verifyJwt: (token: string, options: import("./verifyJwt").VerifyJwtOptions) => Promise<NonNullable<import("@clerk/shared/types").JwtPayload | undefined>>
+ verifyJwt: (token: string, options: VerifyJwtOptions) => Promise<JwtPayload>

Static analyzer: Breaking change in function verifyJwt: Return type changed: !Promise:interface<!NonNullable:type<import("@clerk/shared").JwtPayload|undefined>> → !Promise:interface<import("@clerk/shared").JwtPayload>

🤖 AI review (reclassified as non-breaking) (95%): NonNullable<JwtPayload | undefined> resolves to JwtPayload, so the return type of verifyJwt is structurally unchanged — the new signature is identical to the old one in terms of the resolved type.

🤖 AI review (reclassified as non-breaking) (95%): The only change is a rename from ClerkClient to ClerkClient$1, which is an internal module alias disambiguation; the resolved structural shape of the type is identical, and clerkClient remains an optional field in an input position.

Subpath `./types`

🟡 Non-breaking Changes (2)

Modified: `AuthenticateRequestParams`

  type AuthenticateRequestParams = {
-     clerkClient: ClerkClient;
-     request: Request;

🤖 AI review (reclassified as non-breaking) (90%): The change from ClerkClient to ClerkClient$1 is an internal alias rename; the referenced type definition block shows ClerkMiddlewareOptions uses ClerkClient$1 in the current version, and the structural shape of the ClerkClient type is unchanged — only the internal alias name differs. AuthenticateRequestParams is an internal/output-facing type (used as a field in internal processing), so no consumer-authored values are broken.

Modified: `ClerkMiddlewareOptions`

  type ClerkMiddlewareOptions = AuthenticateRequestOptions & {
-     debug?: boolean;
-     clerkClient?: ClerkClient;
-     frontendApiProxy?: FrontendApiProxyOptions;
+   debug?: boolean;

🤖 AI review (reclassified as non-breaking) (90%): The change from clerkClient?: ClerkClient to clerkClient?: ClerkClient$1 is a rename of an internal alias; the structural shape of the underlying ClerkClient type is identical, and since clerkClient remains optional in both versions, no existing consumer code that omits this field is affected, and consumers passing a value would see the same structural type requirement.

🟡 Non-breaking Changes (1)

Modified: `OAuthConsent`

-     }>, "clerk">): React.JSX.Element | null;
-     displayName: string;
- }

Static analyzer: Breaking change in variable OAuthConsent: Type changed: OAuthConsent:{(props:import("@clerk/shared").Without<import("@clerk/react").WithClerkProp<import("@clerk/shared").OAuth… → OAuthConsent:typeof import("@clerk/react").OAuthConsent

🤖 AI review (reclassified as non-breaking) (85%): The type changed from an explicit structural signature to typeof import("@clerk/react").OAuthConsent, but both resolve to the same callable React component shape — a function accepting the same props and returning React.JSX.Element | null with a displayName property — so existing consumer call sites remain valid.

@clerk/nuxt

Current version: 2.5.3
Recommended bump: MINOR → 2.6.0

Subpath `./server`

🟡 Non-breaking Changes (2)

Modified: `clerkClient`

- declare function clerkClient(event: H3Event): _clerk_backend.ClerkClient;
+ declare function clerkClient(event: H3Event): _$_clerk_backend0.ClerkClient;

Static analyzer: Breaking change in function clerkClient: Parameter event type changed: import("h3").H3Event → import("@clerk/nuxt").H3Event

🤖 AI review (reclassified as non-breaking) (95%): Both import('h3').H3Event and import('@clerk/nuxt').H3Event refer to the same H3Event type (the nuxt package re-exports it from h3), so the resolved structural shape is identical and no consumer code is affected.

Modified: `createRouteMatcher`

  createRouteMatcher: (routes: RouteMatcherParam) => (event: H3Event) => boolean

Static analyzer: Breaking change in function createRouteMatcher: Return type changed: (event:import("h3").H3Event)=>boolean → (event:import("@clerk/nuxt").H3Event)=>boolean

🤖 AI review (reclassified as non-breaking) (95%): The H3Event in the return type's function parameter is structurally identical between import('h3').H3Event and import('@clerk/nuxt').H3Event since @clerk/nuxt re-exports H3Event from h3, so no consumer calling the returned function is affected.

Subpath `./webhooks`

🟡 Non-breaking Changes (1)

Modified: `verifyWebhook`

- declare function verifyWebhook(event: H3Event, options?: VerifyWebhookOptions): Promise<_clerk_backend_webhooks.WebhookEvent>;
+ declare function verifyWebhook(event: H3Event, options?: VerifyWebhookOptions): Promise<_$_clerk_backend0.WebhookEvent>;

Static analyzer: Breaking change in function verifyWebhook: Parameter event type changed: import("h3").H3Event → import("@clerk/nuxt").H3Event

🤖 AI review (reclassified as non-breaking) (85%): Both import("h3").H3Event and import("@clerk/nuxt").H3Event almost certainly resolve to the same underlying H3Event type from the h3 package — @clerk/nuxt likely re-exports it — so the structural shape of the parameter is identical and existing callers passing an H3Event are unaffected.

🤖 AI review (reclassified as non-breaking) (90%): The only textual difference is React.ReactNode vs React$1.ReactNode, which are aliases for the same type — the structural shape of ClerkProviderProps is identical, so no well-typed consumer code is affected.

Modified: `SignInWithMetamaskButton`

  SignInWithMetamaskButton: {

🤖 AI review (reclassified as non-breaking) (85%): _$_clerk_shared__chunks_index_TNda25cs0.jm is a renamed/re-exported alias for the same Without utility type from @clerk/shared; the resolved structural shape of the props parameter is identical, so callers passing Without<WithClerkProp<SignInWithMetamaskButtonProps>, 'clerk'> are unaffected.

Subpath `./internal`

🤖 AI review (reclassified as non-breaking) (85%): The structural shape of Ui is identical between @clerk/ui and @clerk/react (same interface definition provided), and InternalClerkScriptProps$1 is a renamed alias for InternalClerkScriptProps with the same underlying shape — the change is a module source relocation, not a structural API difference.

🤖 AI review (reclassified as non-breaking) (97%): The only difference between the before and after snippets is React.ReactNode vs React$1.ReactNode, which is a module alias rename for the same React type; the resolved structural shape of ClerkProviderProps is identical for consumers.

🟡 Non-breaking Changes (2)

Modified: `OrganizationProfile`

- OrganizationProfile: typeof OrganizationProfile$1
+ OrganizationProfile$1: typeof OrganizationProfile

Static analyzer: Breaking change in variable OrganizationProfile: Type changed: OrganizationProfile:typeof import("@clerk/react").OrganizationProfile → OrganizationProfile$1:typeof import("@clerk/react").OrganizationProfile

🤖 AI review (reclassified as non-breaking) (95%): This is a rename of an internal alias (OrganizationProfile$1 ↔ OrganizationProfile) used in the .d.ts bundle; the resolved type typeof import("@clerk/react").OrganizationProfile is structurally identical before and after, so no consumer-observable type change occurs.

Modified: `UserProfile`

- UserProfile: typeof UserProfile$1
