fix(mosaic): render the profile page title on the server by maxyinger · Pull Request #10085 · clerk/javascript

maxyinger · 2026-10-06T00:01:19Z

Description

The profile's page title (Profile.Content's heading, naming the selected page) was empty in server-rendered HTML and only appeared once the client hydrated. Profile.Nav handed its items to the title through context state set in a layout effect, so the first render, and the SSR output with it, had no label.

Profile.Content now takes the selected page's name as a required pageTitle prop and renders it as the page title, so the heading has its label on the first render and the server emits it. Profile.Nav still renders its items as the tablist and the compact select's options.

Type of change

🤖 Generated with Claude Code

The page title took its label from state that `Profile.Nav` set in a layout effect, so server-rendered HTML carried an empty heading until hydration. `Profile.Root` now reads the nav's children from its own children during render, so the title is in the first render and the SSR output.

📝 Walkthrough

Walkthrough

Profile.Content now requires a pageTitle prop and renders that value as the page heading. User and organization profile views resolve the active entry, fall back to the first entry when needed, and pass its custom or localized title. Tests and examples now provide page titles, and a server-rendering test checks the selected security title.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 10fda

Without a non-empty changeset, users will not receive this profile-title change through the normal Mosaic publish. Add the package changeset before merging.

could we remove the need for computing this with just a little more data orchestration?
