Client Component Not Rendering in App Router
Your client component doesn't render in the Next.js 13+ App Router, or renders blank with no errors. The component markup doesn't appear in the browser or page layout.
This occurs when server/client boundaries aren't properly configured, 'use client' directives are missing or misplaced, or component imports cross server-client boundaries incorrectly.
Error Messages You Might See
[error] 'useState' hook can only be used in client components
Component render aborted
White screen of death
[App Router] Component did not render
Common Causes
- Missing 'use client' directive at top of interactive component file
- 'use client' directive not at very first line before imports
- Client component importing server-only packages (fs, database, etc)
- Server component trying to use hooks (useState, useEffect) without 'use client'
- Parent component is server component, but trying to pass client component children with hooks
How to Fix It
Add 'use client' directive: At the very top of any component using hooks: 'use client' as first line, before imports.
Check component structure: If parent is server, ensure client children are properly wrapped and exported separately.
Debug imports: Verify component doesn't import server-only modules (fs, path, database drivers).
React DevTools: Use React DevTools browser extension to check if component mounts in component tree.

I’m a product-focused engineer and tech leader who builds scalable systems and turns ideas into production-ready platforms.
Over the past years, I’ve worked across startups and fast-moving teams, leading backend architecture, improving system reliability, and shipping products used by thousands of users. My strength is not just writing code — but connecting product vision, technical execution, and business impact.
Alvin Voo
I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

Get HelpFrequently Asked Questions
Where does 'use client' go in my file?
Must be the first line of code, before any imports: 'use client'; import React from 'react';
Do I need use client on every component?
Only components using hooks (useState, useEffect, etc). Server components are default and don't need a directive.
Can a server component use a client component?
Yes, as long as client component is passed as children or props to server component. Wrap appropriately.
