| 26 | +- Custom `EventBus<T>` with strong typing |
| 27 | +- Decoupled communication between components |
| 28 | +- Easy to test and maintain |
| 29 | + |
| 30 | +### 2. **Modern Routing System** |
| 31 | +- Parameter extraction support (`:id` patterns) |
| 32 | +- History API integration |
| 33 | +- Clean route registration pattern |
| 34 | + |
| 35 | +### 3. **Component-Based UI** |
| 36 | +- Reusable utility functions for UI creation |

| 38 | +- Type-safe component interfaces |
| 39 | + |
| 40 | +### 4. **Content-First Design** |
| 41 | +- Structured content management in `/content` folder |
| 42 | +- Reusable content templates |
| 43 | +- Clear separation of data and presentation |
| 44 | + |
| 45 | +### 5. **Strong TypeScript Implementation** |
| 46 | +- Comprehensive type definitions |
| 47 | +- Readonly types for immutable data |
| 48 | +- Proper generic usage |
| 49 | + |
| 50 | +## 🚀 **Recommended Improvements** |
| 51 | + |
| 52 | +### 1. **Enhanced Component Architecture** |
| 53 | + |
| 54 | +Create a more structured component system: |
| 55 | + |
| 56 | +```typescript |
| 57 | +// components/base/Component.ts |
| 58 | +export abstract class Component<T = {}> { |
| 59 | + protected element: HTMLElement; |
| 60 | + protected props: T; |
| 61 | + |
| 62 | + constructor(props: T) { |
| 63 | + this.props = props; |
| 64 | + this.element = this.render(); |
| 65 | + this.bindEvents(); |
| 66 | + } |
| 67 | + |
| 68 | + abstract render(): HTMLElement; |
| 69 | + protected bindEvents(): void {} |
| 70 | + |
| 71 | + public getElement(): HTMLElement { |
| 72 | + return this.element; |
| 73 | + } |
| 74 | + |
| 75 | + public destroy(): void { |
| 76 | + this.element.remove(); |
| 77 | + } |
| 78 | +} |
| 79 | +``` |
| 80 | + |
| 81 | +### 2. **State Management** |
| 82 | + |
| 83 | +Add a simple state management system: |
| 84 | + |
| 85 | +```typescript |
| 86 | +// core/state.ts |
| 87 | +type StateListener<T> = (newState: T, oldState: T) => void; |
| 88 | + |
| 89 | +export class StateManager<T> { |
| 90 | + private state: T; |
| 91 | + private listeners: StateListener<T>[] = []; |
| 92 | + |
| 93 | + constructor(initialState: T) { |
| 94 | + this.state = { ...initialState }; |
| 95 | + } |
| 96 | + |
| 97 | + public getState(): T { |
| 98 | + return { ...this.state }; |
| 99 | + } |
| 100 | + |
| 101 | + public setState(updates: Partial<T>): void { |
| 102 | + const oldState = { ...this.state }; |
| 103 | + this.state = { ...this.state, ...updates }; |
| 104 | + this.listeners.forEach(listener => listener(this.state, oldState)); |
| 105 | + } |
| 106 | + |
| 107 | + public subscribe(listener: StateListener<T>): () => void { |
| 108 | + this.listeners.push(listener); |
| 109 | + return () => { |
| 110 | + this.listeners = this.listeners.filter(l => l !== listener); |
| 111 | + }; |
| 112 | + } |
| 113 | +} |
| 114 | +``` |
| 115 | + |
| 116 | +### 3. **Service Layer** |
| 117 | + |
| 118 | +Create services for external data and API calls: |
| 119 | + |
| 120 | +```typescript |
| 121 | +// services/ContentService.ts |
| 122 | +export class ContentService { |
| 123 | + private static instance: ContentService; |
| 124 | + |
| 125 | + public static getInstance(): ContentService { |
| 126 | + if (!ContentService.instance) { |
| 127 | + ContentService.instance = new ContentService(); |
| 128 | + } |
| 129 | + return ContentService.instance; |
| 130 | + } |
| 131 | + |
| 132 | + public async loadProjectData(projectId: string): Promise<ProjectContent> { |
| 133 | + // Load project data (could be from API, local storage, etc.) |
| 134 | + } |
| 135 | +} |
| 136 | +``` |
| 137 | + |
| 138 | +### 4. **Improved Error Handling** |
| 139 | + |
| 140 | +```typescript |
| 141 | +// core/ErrorHandler.ts |
| 142 | +export class ErrorHandler { |
| 143 | + public static handle(error: Error, context?: string): void { |
| 144 | + console.error(`Error in ${context || 'Application'}:`, error); |
| 145 | + |
| 146 | + // Log to external service in production |
| 147 | + if (process.env.NODE_ENV === 'production') { |
| 148 | + // Send to error tracking service |
| 149 | + } |
| 150 | + |
| 151 | + // Show user-friendly error message |
| 152 | + this.showErrorMessage('Something went wrong. Please try again.'); |
| 153 | + } |
| 154 | + |
| 155 | + private static showErrorMessage(message: string): void { |
| 156 | + // Create error notification component |
| 157 | + } |
| 158 | +} |
| 159 | +``` |
| 160 | + |
| 161 | +### 5. **Performance Optimization** |
| 162 | + |
| 163 | +#### Lazy Loading for Routes |
| 164 | +```typescript |
| 165 | +// core/router.ts - Enhanced version |
| 166 | +export class Router { |
| 167 | + private async loadRoute(routeName: string): Promise<() => HTMLElement> { |
| 168 | + switch (routeName) { |
| 169 | + case 'home': |
| 170 | + const { homeView } = await import('../views/home'); |
| 171 | + return homeView; |
| 172 | + case 'about': |
| 173 | + const { aboutView } = await import('../views/about'); |
| 174 | + return aboutView; |
| 175 | + default: |
| 176 | + return () => this.get404Page(); |
| 177 | + } |
| 178 | + } |
| 179 | +} |
| 180 | +``` |
| 181 | + |
| 182 | +#### Component Caching |
| 183 | +```typescript |
| 184 | +// utils/ComponentCache.ts |
| 185 | +export class ComponentCache { |
| 186 | + private static cache = new Map<string, HTMLElement>(); |
| 187 | + |
| 188 | + public static get(key: string): HTMLElement | undefined { |
| 189 | + return ComponentCache.cache.get(key); |
| 190 | + } |
| 191 | + |
| 192 | + public static set(key: string, component: HTMLElement): void { |
| 193 | + ComponentCache.cache.set(key, component); |
| 194 | + } |
| 195 | + |
| 196 | + public static clear(): void { |
| 197 | + ComponentCache.cache.clear(); |
| 198 | + } |
| 199 | +} |
| 200 | +``` |
| 201 | + |
