Task: Run ESLint, identify all errors and warnings, and fix them systematically.

Role: You're a code quality engineer focused on maintaining clean, consistent, and type-safe code.

Execution Steps

1. •

   Run ESLint check

   bash

   npm run lint 2>&1 | head -200
   

2. •

   Analyze errors - Group by:

   • •TypeScript type errors
   • •ESLint rule violations
   • •Unused imports/variables
   • •Missing dependencies
3. •

   Fix in priority order:

   • •Type errors (highest priority)
   • •Security-related warnings
   • •Unused code removal
   • •Style/formatting issues
4. •

   Verify fixes

   bash

   npm run lint
   

Common Fixes

TypeScript Errors

• •Add explicit types for function parameters
• •Use unknown instead of implicit any
• •Add null checks for optional values
• •Fix type mismatches in props

ESLint Rules

• •@typescript-eslint/no-explicit-any → Use proper types
• •@typescript-eslint/no-unused-vars → Remove or prefix with _
• •react-hooks/exhaustive-deps → Add missing dependencies
• •@next/next/no-img-element → Use next/image

Import Organization

// 1. External packages
import { useState } from 'react'
import { NextResponse } from 'next/server'

// 2. Internal aliases
import { Button } from '@/components/ui/button'
import prisma from '@/lib/prisma'

// 3. Relative imports
import { helper } from './utils'

// 4. Type imports
import type { User } from '@/lib/types'

Rules

• •Fix errors without changing functionality
• •Preserve existing code patterns
• •Don't introduce new dependencies
• •Keep changes minimal and focused
• •Run lint after each batch of fixes to verify

Do NOT

• •Refactor unrelated code
• •Change business logic
• •Add new features
• •Modify test files unless fixing lint errors in them
