I will do error handling in react javascript node

I will professionally debug, fix, and refactor errorhandling in your React, Next.js, Node.js, and SQL fullstack application. I specialize in clean, safe, and userfriendly error workflows across the frontend, backend, and database layer.

What Ill do for you:

• React / Next.js (frontend)
• Implement error boundaries (error.tsx, useErrorBoundary, componentlevel errors).
• Handle API response errors gracefully (HTTP codes, custom messages, loading & error states).
• Add global and routespecific error UIs (404, 500, validation errors).
• Use patterns like try/catch in async components, useActionState, and useFormStatus (Next.js App Router).
• Node.js (backend)
• Build robust Express / Fastifystyle middleware for error handling.
• Log errors safely (with Winston, Pino, or builtin logging).
• Return consistent JSONformatted error responses to frontend.
• Prevent sensitive stack traces from leaking to clients.
• SQL / Database (PostgreSQL, MySQL, etc.)
• Fix SQLspecific errors (constraint violations, duplicate key, syntax, invalid queries).
• Wrap database operations in try/catch with proper rollbacks where needed.
• Integrate with ORMs (Prisma, Sequelize, Knex) for clean DBerror handling.

let's have a conversation.
