⚠️ Potential issue

Avoid sending identifier: null; include the field only when defined

Using identifier || previousIdentifier can yield null, which will serialize as identifier: null. Prefer nullish coalescing and omit the key when undefined.

- const previousIdentifier = this.resource.identifier;- await this.resource.__internal_basePost({- path: this.resource.pathRoot,- body: { identifier: identifier || previousIdentifier, password },- });+ const previousIdentifier = this.resource.identifier;+ const resolvedIdentifier = identifier ?? previousIdentifier ?? undefined;+ await this.resource.__internal_basePost({+ path: this.resource.pathRoot,+ body: {+ ...(resolvedIdentifier !== undefined ? { identifier: resolvedIdentifier } : {}),+ password,+ },+ });

In packages/clerk-js/src/core/resources/SignIn.ts around lines 569 to 574,
replace the identifier || previousIdentifier pattern (which can produce
identifier: null) with logic that uses nullish coalescing and only adds the
identifier key when defined; for example, compute const id = identifier ??
previousIdentifier and build the request body by always including password but
only adding identifier if id !== undefined (and/or !== null if you want to avoid
null explicitly), then pass that body to __internal_basePost so identifier is
omitted from the serialized payload when not defined.

💡 Verification agent

🧩 Analysis chain

Rename to signInResourceSignal is clear; verify callers and mark as internal

Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.

Run this to ensure no leftover references exist:

Apply this diff to mark the export as internal:

+/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });

🏁 Script executed:

#!/bin/bashset -euo pipefail
# Find any remaining references to the old name
rg -n --heading '\bsignInSignal\b' -g '!**/node_modules/**'

Length of output: 365

Update leftover signInSignal references & mark new export as internal

We’ve got three remaining signInSignal references that need to be switched over (and the new export marked @internal):

  • packages/clerk-js/src/core/signals.ts

    +/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });

  • packages/clerk-js/src/core/state.ts (line 13)

    -export const signInSignal = signInComputedSignal;+export const signInResourceSignal = signInComputedSignal;

  • packages/types/src/state.ts (line 32)

    -signInSignal: Signal<SignIn | null>;+signInResourceSignal: Signal<SignIn | null>;

  • packages/react/src/hooks/useClerkSignal.ts (lines 21 & 38)

    -clerk.__internal_state!.signInSignal();+clerk.__internal_state!.signInResourceSignal();-return clerk.__internal_state.signInSignal();+return clerk.__internal_state.signInResourceSignal();

Please make these changes to fully remove the old signInSignal and ensure the new export is marked @internal.

🤖 Prompt for AI Agents
In packages/clerk-js/src/core/signals.ts around line 7, mark the new export
signInResourceSignal as internal by adding a JSDoc @internal comment immediately
above its declaration; then update the three remaining references of the old
signInSignal to the new name across the codebase: change usages in
packages/clerk-js/src/core/state.ts (line 13), packages/types/src/state.ts (line
32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

export const signInErrorSignal = signal<{ error: unknown }>({ error: null });
export const signInFetchSignal = signal<{ status: 'idle' | 'fetching' }>({ status: 'idle' });

export const signInComputedSignal = computed(() => {
const signIn = signInSignal().resource;
const signIn = signInResourceSignal().resource;
const error = signInErrorSignal().error;
const fetchStatus = signInFetchSignal().status;

const errors = errorsToParsedErrors(error);

if (!signIn) {
return { errors, signIn: null };
}

return { errors, signIn: signIn.__internal_future };
return { errors, fetchStatus, signIn: signIn ? signIn.__internal_future : null };

⚠️ Potential issue
Avoid sending identifier: null; include the field only when defined
Using identifier || previousIdentifier can yield null, which will serialize as identifier: null. Prefer nullish coalescing and omit the key when undefined.

🧩 Analysis chain
Rename to signInResourceSignal is clear; verify callers and mark as internal
Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.
Run this to ensure no leftover references exist:
Apply this diff to mark the export as internal:
+/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
🏁 Script executed:
#!/bin/bashset -euo pipefail
# Find any remaining references to the old name
rg -n --heading '\bsignInSignal\b' -g '!**/node_modules/**'
Length of output: 365
Update leftover signInSignal references & mark new export as internal
We’ve got three remaining signInSignal references that need to be switched over (and the new export marked @internal):
  • packages/clerk-js/src/core/signals.ts
    +/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
  • packages/clerk-js/src/core/state.ts (line 13)

  • packages/types/src/state.ts (line 32)

    -clerk.__internal_state!.signInSignal();+clerk.__internal_state!.signInResourceSignal();-return clerk.__internal_state.signInSignal();+return clerk.__internal_state.signInResourceSignal();
Please make these changes to fully remove the old signInSignal and ensure the new export is marked @internal.

In packages/clerk-js/src/core/signals.ts around line 7, mark the new export
signInResourceSignal as internal by adding a JSDoc @internal comment immediately
above its declaration; then update the three remaining references of the old
signInSignal to the new name across the codebase: change usages in
packages/clerk-js/src/core/state.ts (line 13), packages/types/src/state.ts (line
32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

Rename to signInResourceSignal is clear; verify callers and mark as internal
Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.
Run this to ensure no leftover references exist:

In packages/clerk-js/src/core/signals.ts around line 7, mark the new export
signInResourceSignal as internal by adding a JSDoc @internal comment immediately
above its declaration; then update the three remaining references of the old
signInSignal to the new name across the codebase: change usages in
packages/clerk-js/src/core/state.ts (line 13), packages/types/src/state.ts (line
32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

export const signInErrorSignal = signal<{ error: unknown }>({ error: null });
export const signInFetchSignal = signal<{ status: 'idle' | 'fetching' }>({ status: 'idle' });

export const signInComputedSignal = computed(() => {
 const signIn = signInSignal().resource;
 const signIn = signInResourceSignal().resource;
 const error = signInErrorSignal().error;
 const fetchStatus = signInFetchSignal().status;

 const errors = errorsToParsedErrors(error);

 if (!signIn) {

⚠️ Potential issue
Avoid sending identifier: null; include the field only when defined
Using identifier || previousIdentifier can yield null, which will serialize as identifier: null. Prefer nullish coalescing and omit the key when undefined.

replace the identifier || previousIdentifier pattern (which can produce
identifier: null) with logic that uses nullish coalescing and only adds the
identifier key when defined; for example, compute const id = identifier ??
previousIdentifier and build the request body by always including password but
only adding identifier if id !== undefined (and/or !== null if you want to avoid
null explicitly), then pass that body to __internal_basePost so identifier is
omitted from the serialized payload when not defined.

32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

export const signInErrorSignal = signal<{ error: unknown }>({ error: null });
export const signInFetchSignal = signal<{ status: 'idle' | 'fetching' }>({ status: 'idle' });

export const signInComputedSignal = computed(() => {
 const signIn = signInSignal().resource;
 const signIn = signInResourceSignal().resource;
 const error = signInErrorSignal().error;
 const fetchStatus = signInFetchSignal().status;

 const errors = errorsToParsedErrors(error);

 if (!signIn) {
 return { errors, signIn: null };
 }

 return { errors, signIn: signIn.__internal_future };
 return { errors, fetchStatus, signIn: signIn ? signIn.__internal_future : null };
});

⚠️ Potential issue
Avoid sending identifier: null; include the field only when defined
Using identifier || previousIdentifier can yield null, which will serialize as identifier: null. Prefer nullish coalescing and omit the key when undefined.
- const previousIdentifier = this.resource.identifier;- await this.resource.__internal_basePost({- path: this.resource.pathRoot,- body: { identifier: identifier || previousIdentifier, password },- });+ const previousIdentifier = this.resource.identifier;+ const resolvedIdentifier = identifier ?? previousIdentifier ?? undefined;+ await this.resource.__internal_basePost({+ path: this.resource.pathRoot,+ body: {+ ...(resolvedIdentifier !== undefined ? { identifier: resolvedIdentifier } : {}),+ password,+ },+ });

In packages/clerk-js/src/core/resources/SignIn.ts around lines 569 to 574,
replace the identifier || previousIdentifier pattern (which can produce
identifier: null) with logic that uses nullish coalescing and only adds the
identifier key when defined; for example, compute const id = identifier ??
previousIdentifier and build the request body by always including password but
only adding identifier if id !== undefined (and/or !== null if you want to avoid
null explicitly), then pass that body to __internal_basePost so identifier is
omitted from the serialized payload when not defined.

💡 Verification agent
🧩 Analysis chain
Rename to signInResourceSignal is clear; verify callers and mark as internal
Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.
Run this to ensure no leftover references exist:
Apply this diff to mark the export as internal:
+/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
🏁 Script executed:
#!/bin/bashset -euo pipefail
# Find any remaining references to the old name
rg -n --heading '\bsignInSignal\b' -g '!**/node_modules/**'
Length of output: 365
Update leftover signInSignal references & mark new export as internal
We’ve got three remaining signInSignal references that need to be switched over (and the new export marked @internal):
  • packages/clerk-js/src/core/signals.ts
    +/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
  • packages/clerk-js/src/core/state.ts (line 13)
    -export const signInSignal = signInComputedSignal;+export const signInResourceSignal = signInComputedSignal;
  • packages/types/src/state.ts (line 32)
    -signInSignal: Signal<SignIn | null>;+signInResourceSignal: Signal<SignIn | null>;
  • packages/react/src/hooks/useClerkSignal.ts (lines 21 & 38)
    -clerk.__internal_state!.signInSignal();+clerk.__internal_state!.signInResourceSignal();-return clerk.__internal_state.signInSignal();+return clerk.__internal_state.signInResourceSignal();
Please make these changes to fully remove the old signInSignal and ensure the new export is marked @internal.

In packages/clerk-js/src/core/signals.ts around line 7, mark the new export

above its declaration; then update the three remaining references of the old

⚠️ Potential issue
Avoid sending identifier: null; include the field only when defined
Using identifier || previousIdentifier can yield null, which will serialize as identifier: null. Prefer nullish coalescing and omit the key when undefined.
- const previousIdentifier = this.resource.identifier;- await this.resource.__internal_basePost({- path: this.resource.pathRoot,- body: { identifier: identifier || previousIdentifier, password },- });+ const previousIdentifier = this.resource.identifier;+ const resolvedIdentifier = identifier ?? previousIdentifier ?? undefined;+ await this.resource.__internal_basePost({+ path: this.resource.pathRoot,+ body: {+ ...(resolvedIdentifier !== undefined ? { identifier: resolvedIdentifier } : {}),+ password,+ },+ });

In packages/clerk-js/src/core/resources/SignIn.ts around lines 569 to 574,
replace the identifier || previousIdentifier pattern (which can produce
identifier: null) with logic that uses nullish coalescing and only adds the
identifier key when defined; for example, compute const id = identifier ??
previousIdentifier and build the request body by always including password but
only adding identifier if id !== undefined (and/or !== null if you want to avoid
null explicitly), then pass that body to __internal_basePost so identifier is
omitted from the serialized payload when not defined.

💡 Verification agent
🧩 Analysis chain
Rename to signInResourceSignal is clear; verify callers and mark as internal
Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.
Run this to ensure no leftover references exist:
Apply this diff to mark the export as internal:
+/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
🏁 Script executed:
#!/bin/bashset -euo pipefail
# Find any remaining references to the old name
rg -n --heading '\bsignInSignal\b' -g '!**/node_modules/**'
Length of output: 365
Update leftover signInSignal references & mark new export as internal
We’ve got three remaining signInSignal references that need to be switched over (and the new export marked @internal):
  • packages/clerk-js/src/core/signals.ts
    +/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
  • packages/clerk-js/src/core/state.ts (line 13)
    -export const signInSignal = signInComputedSignal;+export const signInResourceSignal = signInComputedSignal;
  • packages/types/src/state.ts (line 32)
    -signInSignal: Signal<SignIn | null>;+signInResourceSignal: Signal<SignIn | null>;
  • packages/react/src/hooks/useClerkSignal.ts (lines 21 & 38)
    -clerk.__internal_state!.signInSignal();+clerk.__internal_state!.signInResourceSignal();-return clerk.__internal_state.signInSignal();+return clerk.__internal_state.signInResourceSignal();
Please make these changes to fully remove the old signInSignal and ensure the new export is marked @internal.

In packages/clerk-js/src/core/signals.ts around line 7, mark the new export
signInResourceSignal as internal by adding a JSDoc @internal comment immediately
above its declaration; then update the three remaining references of the old
signInSignal to the new name across the codebase: change usages in
packages/clerk-js/src/core/state.ts (line 13), packages/types/src/state.ts (line
32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

export const signInErrorSignal = signal<{ error: unknown }>({ error: null });
export const signInFetchSignal = signal<{ status: 'idle' | 'fetching' }>({ status: 'idle' });

export const signInComputedSignal = computed(() => {
 const signIn = signInSignal().resource;
 const signIn = signInResourceSignal().resource;
 const error = signInErrorSignal().error;
 const fetchStatus = signInFetchSignal().status;

 const errors = errorsToParsedErrors(error);

 if (!signIn) {

⚠️ Potential issue
Avoid sending identifier: null; include the field only when defined
Using identifier || previousIdentifier can yield null, which will serialize as identifier: null. Prefer nullish coalescing and omit the key when undefined.

replace the identifier || previousIdentifier pattern (which can produce
identifier: null) with logic that uses nullish coalescing and only adds the
identifier key when defined; for example, compute const id = identifier ??
previousIdentifier and build the request body by always including password but
only adding identifier if id !== undefined (and/or !== null if you want to avoid
null explicitly), then pass that body to __internal_basePost so identifier is
omitted from the serialized payload when not defined.

💡 Verification agent
🧩 Analysis chain
Rename to signInResourceSignal is clear; verify callers and mark as internal
Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.
Run this to ensure no leftover references exist:
Apply this diff to mark the export as internal:
+/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
🏁 Script executed:
#!/bin/bashset -euo pipefail
# Find any remaining references to the old name
rg -n --heading '\bsignInSignal\b' -g '!**/node_modules/**'
Length of output: 365
Update leftover signInSignal references & mark new export as internal
We’ve got three remaining signInSignal references that need to be switched over (and the new export marked @internal):
  • packages/clerk-js/src/core/signals.ts
    +/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
  • packages/clerk-js/src/core/state.ts (line 13)
    -export const signInSignal = signInComputedSignal;+export const signInResourceSignal = signInComputedSignal;
  • packages/types/src/state.ts (line 32)
    -signInSignal: Signal<SignIn | null>;+signInResourceSignal: Signal<SignIn | null>;
  • packages/react/src/hooks/useClerkSignal.ts (lines 21 & 38)
    -clerk.__internal_state!.signInSignal();+clerk.__internal_state!.signInResourceSignal();-return clerk.__internal_state.signInSignal();+return clerk.__internal_state.signInResourceSignal();
Please make these changes to fully remove the old signInSignal and ensure the new export is marked @internal.

In packages/clerk-js/src/core/signals.ts around line 7, mark the new export
signInResourceSignal as internal by adding a JSDoc @internal comment immediately
above its declaration; then update the three remaining references of the old
signInSignal to the new name across the codebase: change usages in
packages/clerk-js/src/core/state.ts (line 13), packages/types/src/state.ts (line
32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

In packages/clerk-js/src/core/resources/SignIn.ts around lines 569 to 574,
replace the identifier || previousIdentifier pattern (which can produce
identifier: null) with logic that uses nullish coalescing and only adds the
identifier key when defined; for example, compute const id = identifier ??
previousIdentifier and build the request body by always including password but
only adding identifier if id !== undefined (and/or !== null if you want to avoid
null explicitly), then pass that body to __internal_basePost so identifier is
omitted from the serialized payload when not defined.

Rename to signInResourceSignal is clear; verify callers and mark as internal
Good separation of responsibilities by renaming to signInResourceSignal. If this is not part of the public API, add an @internal JSDoc to comply with docs guidelines and prevent accidental external usage. Also, please verify there are no lingering imports/usages of the old signInSignal.
Run this to ensure no leftover references exist:
Apply this diff to mark the export as internal:
+/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
🏁 Script executed:
#!/bin/bashset -euo pipefail
# Find any remaining references to the old name

Update leftover signInSignal references & mark new export as internal
We’ve got three remaining signInSignal references that need to be switched over (and the new export marked @internal):
  • packages/clerk-js/src/core/signals.ts
    +/** @internal */
export const signInResourceSignal = signal<{ resource: SignIn | null }>({ resource: null });
  • packages/clerk-js/src/core/state.ts (line 13)
    -export const signInSignal = signInComputedSignal;+export const signInResourceSignal = signInComputedSignal;
  • packages/types/src/state.ts (line 32)
    -signInSignal: Signal<SignIn | null>;+signInResourceSignal: Signal<SignIn | null>;
  • packages/react/src/hooks/useClerkSignal.ts (lines 21 & 38)
    -clerk.__internal_state!.signInSignal();+clerk.__internal_state!.signInResourceSignal();-return clerk.__internal_state.signInSignal();+return clerk.__internal_state.signInResourceSignal();
Please make these changes to fully remove the old signInSignal and ensure the new export is marked @internal.

In packages/clerk-js/src/core/signals.ts around line 7, mark the new export
signInResourceSignal as internal by adding a JSDoc @internal comment immediately
above its declaration; then update the three remaining references of the old
signInSignal to the new name across the codebase: change usages in
packages/clerk-js/src/core/state.ts (line 13), packages/types/src/state.ts (line
32), and packages/react/src/hooks/useClerkSignal.ts (lines 21 and 38) to import
and use signInResourceSignal instead of signInSignal, ensuring any type
imports/exports are updated accordingly so imports resolve and there are no
leftover references to signInSignal.

export const signInErrorSignal = signal<{ error: unknown }>({ error: null });
export const signInFetchSignal = signal<{ status: 'idle' | 'fetching' }>({ status: 'idle' });

export const signInComputedSignal = computed(() => {
 const signIn = signInSignal().resource;
 const signIn = signInResourceSignal().resource;
 const error = signInErrorSignal().error;
 const fetchStatus = signInFetchSignal().status;

 const errors = errorsToParsedErrors(error);

 if (!signIn) {
 return { errors, signIn: null };
 }

 return { errors, signIn: signIn.__internal_future };
 return { errors, fetchStatus, signIn: signIn ? signIn.__internal_future : null };
