In @components/UmamiAnalytics.tsx:
- Around line 13-19: Remove the conflicting async attribute from the Next.js
Script component so the script respects the strategy prop: locate the <Script
id="umami-analytics" ... /> usage in the UmamiAnalytics component and delete the
async prop so it only uses src={umamiSrc}, data-website-id={umamiId} and
strategy="afterInteractive".

7-10: Consider removing or conditionalizing the error log.The
console.errorwill execute on every render when the environment variables are missing, potentially cluttering production logs. Consider either removing it entirely (silent skip) or wrapping it in a development check:♻️ Suggested improvement
if (!umamiSrc || !umamiId) { - console.error("Umami Analytics is not configured."); + if (process.env.NODE_ENV === 'development') { + console.warn("Umami Analytics is not configured."); + } return null; }
3-3: Consider adding an explicit return type annotation.While TypeScript can infer the return type, explicitly annotating exported components improves code documentation and type safety.
♻️ Optional improvement
-export default function UmamiAnalytics() { +export default function UmamiAnalytics(): JSX.Element | null {

16-16: LGTM!The import statement follows the project's established patterns and correctly imports the new UmamiAnalytics component.
96-96: LGTM!The placement of the UmamiAnalytics component is appropriate—rendered alongside the Vercel Analytics component and positioned outside the provider tree to avoid unnecessary re-renders.

1-1: LGTM!Correct import of the Next.js Script component for optimized script loading.

🧩 Analysis chain
🌐 Web query:
Next.js Script component strategy="afterInteractive" async attribute redundant
💡 Result:
Short answer: Yes — for Next.js <Script /> with strategy="afterInteractive" you generally should not add async. afterInteractive behaves like a deferred script (executed after hydration) and Next.js controls loading/execution order; adding async is unnecessary and can break ordering because async executes as soon as downloaded. See Next.js docs and the Chrome/Next.js guidance. [1][2]
Sources
- Next.js Script docs (describes afterInteractive as the default / deferred behavior). [1]
- Chrome for Developers blog post on optimizing third‑party scripts with Next.js (explains afterInteractive ≈ defer and why Script manages loading). [2]
Remove the async attribute — it conflicts with strategy="afterInteractive".
The async attribute executes scripts immediately upon download, which directly contradicts strategy="afterInteractive" that defers execution until after page hydration. Next.js Script component manages loading internally based on the strategy prop; the manual async attribute breaks this intended behavior and can cause the script to load prematurely.
Suggested change
<Script
id="umami-analytics"
src={umamiSrc}
data-website-id={umamiId}
strategy="afterInteractive"
/>
