AI "Code Spaghetti" Component Refactorer

AI coding models love appending new code to existing files rather than creating modular components. That produces 800-line monolithic files that exceed AI context windows. Paste your component below to generate a clean 3-part decomposition blueprint.

Paste React Component (.tsx)

'use client';

import React, { useState, useEffect, useRef } from 'react';
import { createClient } from '@supabase/supabase-js';

// TYPICAL 500+ LINE AI GOD COMPONENT:
// Tangled with 10 state hooks, direct fetch calls, inline modal state, and raw queries!
export default function DashboardGodComponent() {
  const [user, setUser] = useState<any>(null);
  const [projects, setProjects] = useState<any[]>([]);
  const [selectedProject, setSelectedProject] = useState<any>(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState<string | null>(null);
  const [modalOpen, setModalOpen] = useState(false);
  const [projectName, setProjectName] = useState('');
  const [projectDescription, setProjectDescription] = useState('');
  const [isSubmitting, setIsSubmitting] = useState(false);
  const [searchQuery, setSearchQuery] = useState('');
  const [sortOption, setSortOption] = useState('date');
  const [filterTag, setFilterTag] = useState('all');
  const [paymentStatus, setPaymentStatus] = useState('free');
  const [showUpgradeModal, setShowUpgradeModal] = useState(false);

useEffect(() => {
    async function loadData() {
      try {
        const res = await fetch('/api/user/data');
        const data = await res.json();
        setUser(data.user);
        setProjects(data.projects);
      } catch (err: any) {
        setError(err.message);
      } finally {
        setLoading(false);
      }
    }
    loadData();
  }, []);

// Imagine 400 more lines of inline modal JSX, tables, and billing handlers here...
  return (
    <div className="p-8 space-y-6">
      <h1 className="text-2xl font-bold">Projects ({projects.length})</h1>
      {/* 200 lines of table JSX */}
      {modalOpen && (
        <div className="modal">
          {/* 100 lines of modal form JSX */}
        </div>
      )}
    </div>
  );
}

The Context Window Burn

When a component exceeds 500 lines, AI assistants like Cursor and Claude start forgetting previous rules and hallucinating types. Breaking the file into a custom hook and isolated subcomponents speeds up model responses and prevents regression bugs.

High Refactor Priority (God Component)

Component has overloaded responsibilities and should be split.

Total Lines of Code73

Healthy compact file

useState Hook Count10

Overloaded component state

Direct fetch() Invocations2

Data fetching mixed into UI layer

useEffect Lifecycle Hooks1

Acceptable hook count

Recommended 3-Part Architecture

1. Custom Controller Hook (useDashboard.ts)

Move all 10 useState hooks, 1 useEffect hooks, and network functions into a dedicated custom hook returning state and action handlers.

2. Extracted Subcomponents

Split modal dialogs, complex filters, and table rows into separate files under components/dashboard/.

3. Thin Presentation View

The root component simply consumes const data = useDashboard() and renders the layout in under 100 lines.
