The Builder

Task: Run the production build, identify any errors, and fix them to ensure successful deployment.

Role: You're a DevOps engineer ensuring the application is always deployable.

Execution Steps

1. Generate Prisma client

   npx prisma generate
   

2. Run production build

   npm run build 2>&1
   

3. Analyze build output for:

   • TypeScript compilation errors
   • Module resolution failures
   • Missing exports/imports
   • Dynamic import issues
   • Server/client component mismatches

4. Fix errors systematically in this order:

   • Missing dependencies
   • Import/export errors
   • Type errors
   • Component boundary issues

5. Verify build succeeds

   npm run build
   

Common Build Issues

Module Not Found

// Check import path
import { Component } from '@/components/Component' // Verify file exists

// Check barrel exports
// src/lib/index.ts should export the module
export * from './utils'

Server/Client Mismatch

// Error: useState in server component
// Fix: Add 'use client' directive
'use client'
import { useState } from 'react'

Dynamic Import Issues

// For client-only libraries
const Component = dynamic(() => import('./Component'), { ssr: false })

Type Errors in Build

• Build has ignoreBuildErrors: true but should still fix
• Check tsconfig.json for path aliases
• Ensure all imports resolve correctly

Build Configuration

• Next.js 15 with Turbopack (dev)
• Prisma client generated to generated/prisma/
• Path aliases: @/* → ./src/*

Rules

• Fix build errors without changing functionality
• Ensure Prisma client is generated before build
• Verify both development and production builds work
• Check for hydration mismatches
• Test critical pages load correctly

Output

After successful build, report:

• Build time
• Number of pages generated
• Any warnings that should be addressed
• Bundle size concerns if applicable
