# Frontend Page Development: The Cycle of Waiting and Confusion 🎨

The first step of frontend development is often the most difficult
Without APIs or data, how do you start writing a dynamic page?

# 😓 The Reality of Frontend Development Struggles

# ⏳ Waiting Dilemma: Time Passes, Progress Stalls

Real Scenario:

Product Manager: "When will the page be ready?"
Frontend Developer: "Waiting for backend APIs..."
Product Manager: "Can you start with the page structure first?"
Frontend Developer: "Without data structure, how do I know how to render?"

Result:

📅 Project timeline disrupted
😴 Frontend development enters "standby" mode
💸 Development costs continuously rising
😰 Delivery pressure mounting

Common Approach: Write pages based on design mockups and assumptions

// Frontend's guessed data structure
const userInfo = {
  name: 'Username',
  age: 25,
  phone: 'Phone Number',
  createTime: 'Creation Time'
}

// Actual backend returned data structure
const userInfo = {
  user_name: 'Username',
  user_age: 25,
  mobile: 'Phone Number',
  created_at: '2023-01-01T10:00:00Z'
}

Painful Consequences:

🔄 Field name mismatches, complete rewrite needed
📊 Data structure differences, component refactoring
🕐 Issues discovered only during integration, time wasted
😤 Repetitive work, low efficiency

# 💾 Static Data Trap: Maintenance Nightmare

Typical Code:

// User list page
const mockUsers = [
  { id: 1, name: 'John', age: 25, department: 'Tech' },
  { id: 2, name: 'Jane', age: 30, department: 'Product' },
  { id: 3, name: 'Bob', age: 28, department: 'Design' },
  // ... dozens of lines of mock data
]

// Product list page
const mockProducts = [
  { id: 1, title: 'Product 1', price: 99.99, stock: 100 },
  // ... dozens more lines of mock data
]

Accumulated Problems:

🗃️ Code Redundancy: Every component has massive test data
🔧 Difficult Maintenance: Data scattered everywhere, hard to manage uniformly
🎭 Poor Realism: Static data can't simulate real interactions
🧹 Cleanup Trouble: Need to remove one by one before launch
🐛 Hidden Issues: Problems only exposed when connecting to real APIs

# 🌐 External Dependency Risks

Online Mock Tool Issues:

🔒 Data Security: Business data uploaded to third-party platforms
🌍 Network Dependency: Can't develop without internet
💰 Cost Issues: Advanced features require payment
🎛️ Poor Flexibility: Can't deeply customize business logic

Self-built Solution Difficulties:

🔨 Technical Barriers: Need additional backend development skills
⏰ Time Cost: Setting up environment takes longer than developing pages
🛠️ Maintenance Burden: Need to maintain both pages and Mock services

# ✨ MockM: The Liberator of Independent Frontend Development

# 🚀 Instant Startup: Goodbye to Waiting Days

# 2 commands, frontend immediately starts working
npm i -g mockm
mm --config

Instantly Have:

🎯 Complete Data Source: No longer dependent on backend progress
📊 Real Experience: Dynamic data-driven pages
🔄 Standard APIs: RESTful API out of the box
🧹 Zero Code Pollution: Goodbye to temporary Mock data

Web Management Interface

# 📊 Smart Data Generation: More Real Than Real Data

module.exports = util => ({
  db: {
    // Configure once, use forever
    users: util.libObj.mockjs.mock({
      'data|20-50': [{
        'id|+1': 1,
        name: '@name',              // Random name
        avatar: '@image("100x100")', // Random avatar
        'age|18-60': 1,             // Random age
        email: '@email',             // Random email
        'role|1': ['admin', 'user', 'guest'], // Random role
        'createdAt': '@datetime'     // Random creation time
      }]
    }).data
  }
})

Development Experience Revolution:

🎨 Focus on UI: With data, immediately see effects
🔄 Dynamic Testing: Different data on every refresh
📱 Edge Case Coverage: Long text, empty data, extreme values automatically covered
🎯 Real Scenarios: Pagination, search, sorting all available

# 🔄 Standardized APIs: Backend-style Frontend Experience

Auto-generated Complete CRUD:

GET    /users          # User list + pagination search
GET    /users/123      # User details
POST   /users          # Create user
PUT    /users/123      # Update user
DELETE /users/123      # Delete user

Identical Code Patterns:

// Development phase - Using MockM
const api = 'http://localhost:9000'

// Production phase - Switch to real backend
const api = 'https://api.company.com'

// Business code needs no changes!
fetch(`${api}/users`).then(...)

# 🎯 Focus on Value Creation

Say Goodbye to These Time Killers:

❌ Waiting for backend APIs 2-3 days
❌ Writing temporary Mock data 2-4 hours
❌ Cleaning test code 1-2 hours
❌ Refactoring code during integration 4-8 hours

Focus on These Core Values:

✅ User experience design and optimization
✅ Frontend performance and interaction logic
✅ Component reuse and architecture design
✅ Business process and edge case handling

# 📊 Frontend Development Efficiency Comparison

# ⏱️ Time Allocation Changes

Development Stage	Traditional Mode	MockM Mode	Time Saved
Waiting for APIs	2-3 days	0 minutes	100%
Writing Mock	2-4 hours	5 minutes	95%
Code Refactoring	4-8 hours	0 minutes	100%
Cleaning Temp Code	1-2 hours	0 minutes	100%

# 💻 Code Quality Improvement

Traditional Development Mode:

// Temporary Mock data scattered everywhere
const TempUserData = [/*...*/]  // Component A
const MockUsers = [/*...*/]     // Component B
const testData = [/*...*/]      // Component C

// Need to clean up one by one before launch
// ❌ Easy to miss
// ❌ Affects code quality
// ❌ Increases testing burden

MockM Development Mode:

// Unified data source configuration
// Define once in mm.config.js, use globally

// Production-level code
fetch('/api/users')  // ✅ Development and production identical
  .then(res => res.json())
  .then(data => setUsers(data))

// ✅ No cleanup needed
// ✅ Code as documentation
// ✅ Zero maintenance cost

# 🎯 Focus Improvement
