I will fix nextjs hydration and typescript errors in app router
Syed Ayan
About this gig
Description:
STOP! Dont let Hydration Errors ruin your Next.js App's SEO and User Experience.
Are you seeing the dreaded "Hydration failed because the initial UI does not match" error in your console? Or is your Vercel build failing due to strict TypeScript type errors in the App Router?
Next.js 14/15 (App Router) is powerful, but hydration mismatches and SSR (Server-Side Rendering) bugs can be a nightmare to debug. Whether it's a dynamic date mismatch, improper HTML nesting, or window object issues, I am here to fix it!
What I Will Fix For You:
- Hydration Mismatch: Fixing "Text content does not match" errors instantly.
- App Router Bugs: Debugging Server & Client Components conflicts.
- TypeScript Errors: Fixing strict type violations and build-time errors.
- SSR & ISR Issues: Troubleshooting Server Actions and Fetch API.
- Deployment Fixes: Solving Vercel/Netlify build failures.
- UI/UX Glitches: Fixing layout shifts (CLS) and CSS hydration bugs.
Why Me?
- Next.js Specialist: Deep knowledge of App Router architecture.
- Clean Code: I fix the root cause, not just the symptoms.
- Quick Delivery: Most hydration bugs are fixed in a few hours.

FAQ
What do you need to start fixing the error?
I will need access to your GitHub repository or the specific code files where the error occurs. A screenshot of the error message from your browser console or terminal is also very helpful to diagnose the issue quickly.
Can you fix "Hydration failed because the initial UI does not match" errors?
Yes! This is my specialty. I will identify the mismatch between server-side and client-side rendered HTML, whether it's caused by dynamic data (dates/time), improper HTML nesting, or incorrect use of browser APIs like window or localStorage.
Do you support the latest Next.js 14/15 and App Router?
Absolutely. I am an expert in the modern Next.js architecture, including Server Components, Client Components, Server Actions, and the latest metadata API. I ensure your code follows the latest best practices.
Can you fix TypeScript "Build Failed" errors on Vercel?
Yes. I can resolve all strict TypeScript type errors, interface mismatches, and configuration issues that prevent your project from deploying successfully on Vercel or Netlify.
