Why

renderElement (function) → useRender (hook). Wins:

1. render-as-element. Today every override must be a function wrapper. Now pass the element directly.

// before<Triggerrender={props=><Link{...props}href="/home"/>}/>// after<Triggerrender={<Linkhref="/home"/>}/>

2. ref merging moves inside. Drop the per-call-site useMergeRefs.

// beforeconstcombinedRef=useMergeRefs([popupRef,refs.setFloating,ref]);if(!mounted)returnnull;returnrenderElement({defaultTagName: 'div', render,props: {ref: combinedRef, ...rest}});// afterconstel=useRender({defaultTagName: 'div', render,enabled: mounted,ref: [popupRef,refs.setFloating,ref],props: rest});if(!el)returnnull;returnel;

3. Mosaic: one path, no cast.

// beforeif(render)returnrenderElement({defaultTagName: 'h2', render,props: { ref, ...root, ...rest}asRecord<string,unknown>});return<h2ref={ref}{...root}{...rest}/>;// afterreturnuseRender({defaultTagName: 'h2', render, ref,props: { ...root, ...rest}});

Also aligns with base-ui (swingset already uses real base-ui useRender).

Scope

PR1 of a phased series. Adds useRender (own utils/use-render.tsx), keeps renderElement exported for the rest of the migration. Migrates Mosaic Box/Heading/Text + dialog-trigger/dialog-popup as representative patterns. Follow-ups convert remaining ~60 primitives by family; final PR deletes renderElement.

Reuses Clerk's mergeProps + useMergeRefs (@floating-ui/react, already a dep). No new runtime dep, no base-ui engine vendored.

Empty changeset: @clerk/headless private, migrated Mosaic parts not in @clerk/ui public exports (matches #9208).

Verified

@clerk/headless typecheck + 601 tests pass. @clerk/ui type-check clean.

@alexcarpenter
feat(headless): add useRender hook alongside renderElement
3445cc3
Introduces a base-ui-style useRender hook: a render prop that accepts a
React element (render={<Link/>}) or a function, with internal ref merging
and state-to-data-attribute mapping. renderElement stays exported for the
phased migration. Migrates Mosaic Box, Heading, Text and the dialog
trigger/popup primitives onto the hook.

Warning

Review limit reached

@alexcarpenter, you've reached your PR review limit, so we couldn't start this review.

Next review available in:33 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Why
renderElement (function) → useRender (hook). Wins:
1. render-as-element. Today every override must be a function wrapper. Now pass the element directly.
// before<Triggerrender={props=><Link{...props}href="/home"/>}/>// after<Triggerrender={<Linkhref="/home"/>}/>
2. ref merging moves inside. Drop the per-call-site useMergeRefs.
// beforeconstcombinedRef=useMergeRefs([popupRef,refs.setFloating,ref]);if(!mounted)returnnull;returnrenderElement({defaultTagName: 'div', render,props: {ref: combinedRef, ...rest}});// afterconstel=useRender({defaultTagName: 'div', render,enabled: mounted,ref: [popupRef,refs.setFloating,ref],props: rest});if(!el)returnnull;returnel;
3. Mosaic: one path, no cast.
// beforeif(render)returnrenderElement({defaultTagName: 'h2', render,props: { ref, ...root, ...rest}asRecord<string,unknown>});return<h2ref={ref}{...root}{...rest}/>;// afterreturnuseRender({defaultTagName: 'h2', render, ref,props: { ...root, ...rest}});
Also aligns with base-ui (swingset already uses real base-ui useRender).
Scope
PR1 of a phased series. Adds useRender (own utils/use-render.tsx), keeps renderElement exported for the rest of the migration. Migrates Mosaic Box/Heading/Text + dialog-trigger/dialog-popup as representative patterns. Follow-ups convert remaining ~60 primitives by family; final PR deletes renderElement.
Reuses Clerk's mergeProps + useMergeRefs (@floating-ui/react, already a dep). No new runtime dep, no base-ui engine vendored.
Empty changeset: @clerk/headless private, migrated Mosaic parts not in @clerk/ui public exports (matches #9208).
Verified
@clerk/headless typecheck + 601 tests pass. @clerk/ui type-check clean.
@alexcarpenter
feat(headless): add useRender hook alongside renderElement
3445cc3
Introduces a base-ui-style useRender hook: a render prop that accepts a
React element (render={<Link/>}) or a function, with internal ref merging
and state-to-data-attribute mapping. renderElement stays exported for the
phased migration. Migrates Mosaic Box, Heading, Text and the dialog
trigger/popup primitives onto the hook.

Warning
Review limit reached
@alexcarpenter, you've reached your PR review limit, so we couldn't start this review.
Next review available in:33 minutes
Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.

You're only billed for reviews past your plan's rate limits ($0.25/file).
How can I continue?
After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.
To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.
How do review limits work?
CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.
For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.
Please refer docs for additional details.

Why
renderElement (function) → useRender (hook). Wins:
1. render-as-element. Today every override must be a function wrapper. Now pass the element directly.
// before<Triggerrender={props=><Link{...props}href="/home"/>}/>// after<Triggerrender={<Linkhref="/home"/>}/>
2. ref merging moves inside. Drop the per-call-site useMergeRefs.
// beforeconstcombinedRef=useMergeRefs([popupRef,refs.setFloating,ref]);if(!mounted)returnnull;returnrenderElement({defaultTagName: 'div', render,props: {ref: combinedRef, ...rest}});// afterconstel=useRender({defaultTagName: 'div', render,enabled: mounted,ref: [popupRef,refs.setFloating,ref],props: rest});if(!el)returnnull;returnel;
3. Mosaic: one path, no cast.
// beforeif(render)returnrenderElement({defaultTagName: 'h2', render,props: { ref, ...root, ...rest}asRecord<string,unknown>});return<h2ref={ref}{...root}{...rest}/>;// afterreturnuseRender({defaultTagName: 'h2', render, ref,props: { ...root, ...rest}});
Also aligns with base-ui (swingset already uses real base-ui useRender).
Scope
PR1 of a phased series. Adds useRender (own utils/use-render.tsx), keeps renderElement exported for the rest of the migration. Migrates Mosaic Box/Heading/Text + dialog-trigger/dialog-popup as representative patterns. Follow-ups convert remaining ~60 primitives by family; final PR deletes renderElement.
Reuses Clerk's mergeProps + useMergeRefs (@floating-ui/react, already a dep). No new runtime dep, no base-ui engine vendored.
Empty changeset: @clerk/headless private, migrated Mosaic parts not in @clerk/ui public exports (matches #9208).
Verified
@clerk/headless typecheck + 601 tests pass. @clerk/ui type-check clean.
@alexcarpenter
feat(headless): add useRender hook alongside renderElement
3445cc3
Introduces a base-ui-style useRender hook: a render prop that accepts a
React element (render={<Link/>}) or a function, with internal ref merging
and state-to-data-attribute mapping. renderElement stays exported for the
phased migration. Migrates Mosaic Box, Heading, Text and the dialog
trigger/popup primitives onto the hook.

Warning
Review limit reached
@alexcarpenter, you've reached your PR review limit, so we couldn't start this review.
Next review available in:33 minutes
Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.

You're only billed for reviews past your plan's rate limits ($0.25/file).
How can I continue?
After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.
To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.
How do review limits work?
CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.
For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.
Please refer docs for additional details.

Why
renderElement (function) → useRender (hook). Wins:
1. render-as-element. Today every override must be a function wrapper. Now pass the element directly.
// before<Triggerrender={props=><Link{...props}href="/home"/>}/>// after<Triggerrender={<Linkhref="/home"/>}/>
2. ref merging moves inside. Drop the per-call-site useMergeRefs.
// beforeconstcombinedRef=useMergeRefs([popupRef,refs.setFloating,ref]);if(!mounted)returnnull;returnrenderElement({defaultTagName: 'div', render,props: {ref: combinedRef, ...rest}});// afterconstel=useRender({defaultTagName: 'div', render,enabled: mounted,ref: [popupRef,refs.setFloating,ref],props: rest});if(!el)returnnull;returnel;
3. Mosaic: one path, no cast.
// beforeif(render)returnrenderElement({defaultTagName: 'h2', render,props: { ref, ...root, ...rest}asRecord<string,unknown>});return<h2ref={ref}{...root}{...rest}/>;// afterreturnuseRender({defaultTagName: 'h2', render, ref,props: { ...root, ...rest}});
Also aligns with base-ui (swingset already uses real base-ui useRender).
Scope
PR1 of a phased series. Adds useRender (own utils/use-render.tsx), keeps renderElement exported for the rest of the migration. Migrates Mosaic Box/Heading/Text + dialog-trigger/dialog-popup as representative patterns. Follow-ups convert remaining ~60 primitives by family; final PR deletes renderElement.
Reuses Clerk's mergeProps + useMergeRefs (@floating-ui/react, already a dep). No new runtime dep, no base-ui engine vendored.
Empty changeset: @clerk/headless private, migrated Mosaic parts not in @clerk/ui public exports (matches #9208).
Verified
@clerk/headless typecheck + 601 tests pass. @clerk/ui type-check clean.
@alexcarpenter
feat(headless): add useRender hook alongside renderElement
3445cc3
Introduces a base-ui-style useRender hook: a render prop that accepts a
React element (render={<Link/>}) or a function, with internal ref merging
and state-to-data-attribute mapping. renderElement stays exported for the
phased migration. Migrates Mosaic Box, Heading, Text and the dialog
trigger/popup primitives onto the hook.

Warning
Review limit reached
@alexcarpenter, you've reached your PR review limit, so we couldn't start this review.
Next review available in:33 minutes
Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.

You're only billed for reviews past your plan's rate limits ($0.25/file).
How can I continue?
After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.
To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.
How do review limits work?
CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.
For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.
Please refer docs for additional details.
