Add Vercel Toolbar integration #448
Conversation
This commit integrates the Vercel Toolbar into the application to enable better collaboration and feedback. The toolbar is conditionally rendered based on the environment (development, preview) or if a user is authenticated in production. - Added @vercel/toolbar dependency. - Created VercelToolbarWrapper component in components/vercel-toolbar.tsx. - Integrated VercelToolbarWrapper into the root layout with a Suspense boundary.

The main concern is the production access control: !!user is a very broad condition and may expose the Vercel Toolbar to any logged-in user, conflicting with the stated goal of limiting it to team members. Additionally, the environment checks rely on build-time inlined process.env values in a client component, which may not match runtime expectations depending on deployment/promotion flow.

app/layout.tsx:97-102
TheSuspenseboundary here likely doesn’t do what you want.VercelToolbarWrapperdoesn’t suspend (noReact.lazy, nouse()), sofallback={null}is effectively unused. If you added this to avoid hydration issues, note that Suspense won’t prevent them unless the child actually suspends.
If your goal is to avoid SSR/hydration discrepancies for a client-only toolbar, consider a client-only dynamic import with ssr: false (or ensure the wrapper intentionally suspends).

isEmployee is derived as !!user, which effectively enables the toolbar for any authenticated user, not specifically “team members/employees” as described in the PR context. If production auth includes regular end-users, this could unintentionally expose the toolbar in production.
Consider tightening this to a role/claim check (e.g., user.isStaff, user.email domain allowlist, or a server-issued claim), and ideally gating with an explicit env flag so it can be disabled quickly without code changes.
Suggestion
Update the production gating logic to check a stricter authorization signal than !!user, and optionally add an explicit kill-switch env var.
Example:
- Add
NEXT_PUBLIC_ENABLE_VERCEL_TOOLBARfor dev/preview toggling. - Replace
const isEmployee = !!user;with a real predicate, e.g.const isStaff = user?.roles?.includes('staff') || user?.email?.endsWith('@yourdomain.com');(whatever your auth model supports).
Then gate with:
const enabledByEnv = process.env.NEXT_PUBLIC_ENABLE_VERCEL_TOOLBAR === 'true'
const isDevelopment = process.env.NODE_ENV === 'development'
const isPreview = process.env.NEXT_PUBLIC_VERCEL_ENV === 'preview'
const isStaff = /* stricter check */
if (enabledByEnv && (isDevelopment || isPreview || isStaff)) return <VercelToolbar />

In a client component, process.env.* values are statically inlined at build time. That’s fine for NODE_ENV and NEXT_PUBLIC_VERCEL_ENV, but be aware this isn’t a runtime check and can behave unexpectedly across builds/promotions (e.g., an image built for preview later promoted).
If you need runtime-accurate environment detection, prefer a server-provided flag (via props) or a lightweight endpoint that returns environment + entitlement, then render accordingly.
Suggestion
If environment/entitlement must be runtime-accurate, compute the “should show toolbar” decision on the server and pass it to the client wrapper.
Example approach:
- In a server component (or layout), compute
const showToolbar = /* env + auth */. - Render
<VercelToolbarWrapper enabled={showToolbar} />and in the client component only render based on the prop.

User description
Integrated the Vercel Toolbar into the project following the official documentation. The implementation ensures that the toolbar is active in development and preview environments, and for authenticated users in production, preventing unauthorized access in the production environment while still enabling it for team members.
