Remix CRUD - Perfect Transition from CodeIgniter to Remix

Migrate from PHP/CodeIgniter to Node.js/Remix while keeping the familiar development experience and gaining modern performance and UX.

---

❌ PHP/CodeIgniter Disadvantages

1. Poor User Experience

• Full page reload on every action
• Slow loading with white screen time
• Long wait time after form submission

2. Development Efficiency Limitations

• Difficult frontend/backend separation
• Repetitive CRUD code
• Manual SQL writing for every table

3. Outdated Ecosystem

• Lack of modern frontend components
• Package management not as convenient as npm
• No type checking

4. Deployment and Scaling Limitations

• Dependent on Apache/PHP environment
• Difficult to containerize
• Complex horizontal scaling

---

❌ Remix Disadvantages

1. Steep Learning Curve

• React Hooks, component lifecycle concepts
• Complex TypeScript type system
• Too much boilerplate code

2. Missing Model Layer

• No Model like CodeIgniter
• Need to write CRUD logic for every table
• Lots of repetitive SQL code

3. Over-complicated Routing

• Multiple files needed to handle one resource
• _index.tsx, $id.tsx, edit.$id.tsx scattered
• Not as clear as CodeIgniter's Controller

---

✅ Our Solution

🎯 Core Philosophy: Take the best, leave the rest

We created a minimalist architecture that solves all disadvantages of both PHP and Remix:

1. BaseModel - Auto-generated SQL

Problem: Both PHP and Remix require manual repetitive CRUD SQL

Solution:

// ❌ Traditional way (both PHP and Remix)
db.prepare("INSERT INTO users (name, email) VALUES (?, ?)").run(name, email);
db.prepare("UPDATE users SET name = ?, email = ? WHERE id = ?").run(name, email, id);

// ✅ Our way: Auto-generated SQL
const userBase = new BaseModel('users');

userBase.create({ name, email });           // 👈 Auto-generates INSERT
userBase.update(id, { name, email });       // 👈 Auto-generates UPDATE
userBase.delete(id);                        // 👈 Auto-generates DELETE

Advantages:

• ✅ Zero SQL code
• ✅ Auto-generates correct SQL based on object
• ✅ Supports any field combination

---

2. Optional Parameter Routing - One File Does It All

Problem: Remix needs multiple files to handle one resource

Solution:

// ❌ Traditional Remix (needs 2-3 files)
users._index.tsx       → /users
users.$id.tsx         → /users/:id
users.edit.$id.tsx    → /users/edit/:id

// ✅ Our way: One file
users.($action).($id).tsx  → /users, /users/edit/1

Code Example:

// app/routes/users.($action).($id).tsx
const userBase = new BaseModel('users');

export async function loader({ params }) {
  // GET /users/edit/1
  if (params.action === 'edit' && params.id) {
    return json({ user: userBase.getById(params.id) });
  }
  
  // GET /users
  return json({ users: userBase.getAll() });
}

export async function action({ request }) {
  const formData = await request.formData();
  
  if (intent === "create") {
    userBase.create({ 
      name: formData.get("name"),
      email: formData.get("email")
    });  // 👈 Auto-generates SQL!
  }
}

Advantages:

• ✅ One file = Complete CRUD
• ✅ As clear as CodeIgniter Controller
• ✅ Reduces 80% file count

---

3. Flexible Type System - Your Choice

Problem: TypeScript too complex vs PHP has no type checking

Solution: We support both ways, you choose!

// app/models/User.model.ts

// Define interface (optional)
export interface User {
  id: number;
  name: string;
  email: string;
}

// ✅ Way 1: With types (TypeScript lovers)
export const userBaseTyped = new BaseModel<User>('users');

// ✅ Way 2: Fully any (PHP developers)
export const userBase = new BaseModel('users');

Usage Comparison:

// Way 1: Type hints (editor auto-complete)
const users: User[] = userBaseTyped.getAll();
users[0].name  // ✅ Editor suggests name, email properties
users[0].nmae  // ❌ Editor error: property doesn't exist

// Way 2: No types (like PHP, free and flexible)
const users = userBase.getAll();
users[0].name  // ✅ Works, but no auto-complete
users[0].anything  // ✅ No error, runtime only knows

Advantages:

• ✅ Free choice: Want type safety? Use <User>. Want flexibility? Don't.
• ✅ Same BaseModel, two ways to use
• ✅ Team can mix and match

💻 Complete Code Example

BaseModel (Core)

// app/models/BaseModel.ts
export class BaseModel<T = any> {
  constructor(tableName: string) { }
  
  getAll(): T[]
  getById(id: any): T | undefined
  
  // 👇 Auto-generates SQL based on object
  create(data: any): T | undefined {
    const keys = Object.keys(data);
    const values = Object.values(data);
    const sql = `INSERT INTO ${tableName} (${keys.join(', ')}) VALUES (${keys.map(() => '?').join(', ')})`;
    // Auto-generates: INSERT INTO users (name, email) VALUES (?, ?)
  }
  
  update(id: any, data: any): T | undefined {
    const keys = Object.keys(data);
    const values = Object.values(data);
    const sql = `UPDATE ${tableName} SET ${keys.map(k => `${k} = ?`).join(', ')} WHERE id = ?`;
    // Auto-generates: UPDATE users SET name = ?, email = ? WHERE id = ?
  }
  
  delete(id: any): boolean
}

Route File (One file does it all)

// app/routes/users.($action).($id).tsx
import { BaseModel } from "~/models/BaseModel";

const userBase = new BaseModel('users');

export async function loader({ params }) {
  if (params.action === 'edit' && params.id) {
    return json({ user: userBase.getById(params.id) });
  }
  return json({ users: userBase.getAll() });
}

export async function action({ request }) {
  const formData = await request.formData();
  const intent = formData.get("intent");
  
  if (intent === "create") {
    userBase.create({ 
      name: formData.get("name"), 
      email: formData.get("email") 
    });
  }
  
  if (intent === "update") {
    userBase.update(params.id, { 
      name: formData.get("name"), 
      email: formData.get("email") 
    });
  }
  
  if (intent === "delete") {
    userBase.delete(formData.get("id"));
  }
  
  return redirect("/users");
}

export default function Users() {
  const { users, user } = useLoaderData();
  
  if (user) {
    return <EditView user={user} />;
  }
  
  return <IndexView users={users} />;
}

🎯 Quick Start

1. Install Dependencies

npm install

2. Start Development

npm run dev

3. Visit Application

http://localhost:5173/users

4. Create New Table (3 Steps)

Step 1: Create Database Table

// app/config/database.ts
db.exec(`
  CREATE TABLE IF NOT EXISTS products (
    id INTEGER PRIMARY KEY,
    name TEXT NOT NULL,
    price REAL NOT NULL
  )
`);

Step 2: Create Route File

// app/routes/products.($action).($id).tsx
const productBase = new BaseModel('products');

export async function loader({ params }) {
  if (params.action === 'edit' && params.id) {
    return json({ product: productBase.getById(params.id) });
  }
  return json({ products: productBase.getAll() });
}

export async function action({ request }) {
  const formData = await request.formData();
  
  if (intent === "create") {
    productBase.create({
      name: formData.get("name"),
      price: formData.get("price")
    });  // 👈 Auto-generates: INSERT INTO products (name, price) VALUES (?, ?)
  }
}

Step 3: Done!

That simple!

Note: User.model.ts is optional, only for type system demo. You can:

• Skip it: Directly new BaseModel('users') in routes (like PHP)
• Use it: Import userBase or userBaseTyped (with type hints)

🎓 Key Innovations

1. Auto SQL Generation

No SQL writing needed, BaseModel auto-generates based on passed object

2. Optional Parameter Routing

users.($action).($id).tsx matches:

• /users → List
• /users/edit/1 → Edit

3. Flexible Type System

Two ways to use in routes:

// app/routes/users.($action).($id).tsx

// ✅ Way 1: Direct creation (no types, simplest)
const userBase = new BaseModel('users');

export async function loader({ params }) {
  const users = userBase.getAll();  // any[]
  return json({ users });
}

// ✅ Way 2: Import with types (has hints)
import { userBaseTyped, User } from "~/models/User.model";

export async function loader({ params }) {
  const users = userBaseTyped.getAll();  // User[]
  return json({ users });
}

Your Choice:

• 🟢 Beginners/PHP developers → Way 1 (direct creation, no types)
• 🔵 TypeScript lovers → Way 2 (import, with types)
• 🟣 Team projects → Mix (each takes what they need)
