ViewLogic Router
A revolutionary Vue 3 routing system with View-Logic separation and Zero Build Development
🎯 Core Philosophy: Simplicity Through Design
ViewLogic Router revolutionizes Vue development with two fundamental core principles:
🎭 View-Logic Separation
Complete separation between View (presentation) and Logic (business logic). Views are pure HTML templates, logic is pure JavaScript components, making your code more maintainable, testable, and scalable.
🚀 Zero Build Development
Zero build step required in development mode. Work directly with source files, see changes instantly without any compilation, bundling, or build processes. True real-time development experience.
✨ Key Features
- 🚀 Ultra-Lightweight - Complete routing system in just 13KB gzipped (48KB minified)
- 🔄 Multiple API Support - Parallel data fetching from multiple APIs with named data storage
- 📝 Automatic Form Handling - Revolutionary form submission with
{paramName}variable parameters - 🛠️ Built-in Components - Preloaded UI components including revolutionary DynamicInclude & HtmlInclude
- 🔗 Query-Based Parameter System - Simple query-only parameters (
/users?id=123) instead of complex path parameters - ⚡ Optimized Production - Pre-built individual route bundles for lightning-fast production
- 📁 Intuitive Structure - Organized folder structure for views, logic, styles, layouts, and components
- 💾 Smart Caching - Intelligent route and component caching
- 🔐 Authentication - Built-in auth management system
- 🌐 i18n Ready - Built-in internationalization support

const router = new ViewLogicRouter({ environment: 'development' });
router.navigateTo('products', { id: 123, category: 'electronics' });
const current = router.getCurrentRoute();
// In route components - global methods automatically available:
export default {
dataURL: '/api/products', // Auto-fetch data
mounted() {
const id = this.getParam('id'); // Get parameter
this.navigateTo('detail', { id }); // Navigate
console.log('Data loaded:', this.products); // From dataURL
if (this.$isAuthenticated()) { /* auth check */ }
const text = this.$t('welcome.message'); // i18n
}
};Key Global Methods (Auto-available in all route components)
- Navigation:
navigateTo(),getCurrentRoute() - Parameters:
getParams(),getParam(key, defaultValue) - Data Fetching:
$fetchData(),$fetchAllData()(with dataURL) - Authentication:
$isAuthenticated(),$getToken(),$logout() - Forms: Auto-binding with
actionattribute and{param}templates - i18n:
$t(key, params)for translations
Auto-Injected Properties
// Automatically available in every route component:
// currentRoute, $query, $lang, $dataLoading🎯 View-Logic Separation: Core Philosophy in Action
ViewLogic Router's fundamental philosophy of View-Logic Separation creates clear boundaries between concerns:
Philosophy Benefits
- 🎨 Pure Presentation: Views contain only HTML - no mixed logic or scripts
- 🧠 Pure Logic: JavaScript components focus solely on business logic
- ⚡ Zero Build Required: Work directly with separate files in development
- 🔄 Hot Reload: Instant changes without compilation or bundling
File Structure (Core Philosophy)
- View:
src/views/products.html- Pure HTML template - Logic:
src/logic/products.js- Pure Vue component logic - Style:
src/styles/products.css- Pure CSS styles
Example: Philosophy in Practice
// src/logic/products.js - Pure business logic
export default {
name: 'ProductsList',
dataURL: '/api/products', // Auto-fetch data
data() {
return { title: 'Our Products' };
},
methods: {
viewDetail(id) {
this.navigateTo('product-detail', { id });
}
}
};Production: Automatic Optimization
All separate files automatically combine into optimized bundles in routes/ folder - maintaining the development philosophy while optimizing for production.
🔄 Zero Build Development vs Optimized Production
ViewLogic Router's Zero Build Development (core philosophy) vs optimized production:
| Mode | Philosophy | Files | Requests | Experience | |------|------------|-------|----------|------------| | Development | Zero Build Required | Separate files | 4 per route | Real-time, instant changes | | Production | Optimized Performance | Single bundle | 1 per route | Lightning-fast loading |
// Zero Build Development (Core Philosophy)
ViewLogicRouter({ environment: 'development' }); // Work directly with source files
// Optimized Production
ViewLogicRouter({ environment: 'production' }); // Use pre-built bundlesZero Build Development Benefits
- ⚡ Instant Changes - Edit HTML/JS/CSS and see changes immediately
- 🚀 Zero Setup - No webpack, vite, or build tools required

ViewLogic Router includes revolutionary automatic data fetching that eliminates manual API calls in component lifecycle hooks.
Single API (Simple Usage)
// src/logic/products/list.js
export default {
name: 'ProductsList',
dataURL: '/api/products', // ✨ Magic happens here!
data() {
return {
title: 'Our Products'
// products: [] - No need to declare, auto-populated from API
};
},
mounted() {
// Data is already fetched and available!
console.log('Products loaded:', this.products);
console.log('Loading state:', this.$dataLoading);
},
methods: {
async refreshData() {
// Manual refresh if needed
await this.$fetchData();
}
}
};Multiple APIs (Advanced Usage) - 🆕 Revolutionary!
// src/logic/dashboard/main.js
export default {
name: 'DashboardMain',
dataURL: {
products: '/api/products',
categories: '/api/categories',
stats: '/api/dashboard/stats',
user: '/api/user/profile'
}, // ✨ Multiple APIs with named data!
data() {
return {
title: 'Dashboard'
// products: [], categories: [], stats: {}, user: {}
// All auto-populated from respective APIs!
};
},
mounted() {
// All APIs called in parallel, data available by name!
console.log('Products:', this.products);
console.log('Categories:', this.categories);
console.log('Stats:', this.stats);
console.log('User:', this.user);
console.log('Loading state:', this.$dataLoading);
},
methods: {
async refreshProducts() {
// Refresh specific API only
await this.$fetchData('products');
},
async refreshStats() {
// Refresh specific API only
await this.$fetchData('stats');
},
async refreshAllData() {
// Refresh all APIs
await this.$fetchAllData();
}
}
};Features:
- Zero-Config API Calls - Just define
dataURLand data is automatically fetched - 🆕 Multiple API Support - Define multiple APIs with custom names
- 🚀 Parallel Processing - Multiple APIs called simultaneously for best performance

Common Use Cases
- Single API:
dataURL: '/api/products'- Product listings, user profiles, articles - Multiple APIs:
dataURL: { stats: '/api/stats', users: '/api/users' }- Dashboards, admin panels - Dynamic Content:
<DynamicInclude page="login" :params="{ theme: 'compact' }" /> - HTML Includes:
<HtmlInclude src="/widgets/weather.html" :sanitize="true" />
Advantages
- ✅ Auto Data Fetching with
dataURLproperty (others: manual logic) - ✅ Parameter Integration - Query params sent automatically
- ✅ Loading States -
$dataLoadingauto-managed - ✅ Built-in Security - HTML sanitization included
- ✅ Zero Setup - Works immediately without configuration
📝 Automatic Form Handling with Variable Parameters
ViewLogic Router includes revolutionary automatic form handling that eliminates the need for manual form submission logic. Just define your forms with action attributes and the router handles the rest!
Basic Form Handling
<!-- src/views/contact.html -->
<div class="contact-page">
<h1>Contact Us</h1>
<form action="/api/contact" method="POST">
<input type="text" name="name" required placeholder="Your Name">
<input type="email" name="email" required placeholder="Your Email">
<textarea name="message" required placeholder="Your Message"></textarea>
<button type="submit">Send Message</button>
</form>
</div>// src/logic/contact.js
export default {
name: 'ContactPage',
mounted() {
// Forms are automatically bound - no additional code needed!
// Form submission will automatically POST to /api/contact
console.log('Form handling is automatic!');
}
};Variable Parameter Forms - 🆕 Revolutionary!
The most powerful feature is variable parameter support in action URLs. You can use simple template syntax to inject dynamic values:
<!-- Dynamic form actions with variable parameters -->
<form action="/api/users/{userId}/posts" method="POST"
data-success="handlePostSuccess"
data-error="handlePostError">
<input type="text" name="title" required placeholder="Post Title">
<textarea name="content" required placeholder="Post Content"></textarea>
<button type="submit">Create Post</button>
</form>
<!-- Order update with dynamic order ID -->
<form action="/api/orders/{orderId}/update" method="PUT"
data-success="orderUpdated"
data-redirect="/orders">
<input type="number" name="quantity" required>
<select name="status">
<option value="pending">Pending</option>
<option value="processing">Processing</option>
<option value="completed">Completed</option>
</select>
<button type="submit">Update Order</button>
</form>
<!-- File upload support -->
<form action="/api/profile/{userId}/avatar" method="POST" enctype="multipart/form-data"
data-success="avatarUploaded">
<input type="file" name="avatar" accept="image/*" required>
<button type="submit">Upload Avatar</button>
</form>// Component logic - parameters are resolved automatically
export default {
name: 'UserProfile',
data() {
return {
userId: 123, // {userId} will be replaced with this value
orderId: 456 // {orderId} will be replaced with this value
};
},
methods: {
handlePostSuccess(response) {
console.log('Post created successfully!', response);
},
orderUpdated(response) {
console.log('Order updated!', response);
}
}
};How Parameter Resolution Works
Parameters are resolved automatically from multiple sources in this order:
- Route Parameters:
this.getParam('paramName')- from URL query parameters - Component Data:
this.paramName- from component's data properties - Computed Properties:
this.paramName- from component's computed properties
// Component example
export default {
name: 'UserProfile',
data() {
return {
userId: 123, // Available as {userId} in action URLs
productId: 456 // Available as {productId} in action URLs
};
},
computed: {
currentOrderId() { // Available as {currentOrderId} in action URLs
return this.getParam('orderId') || this.defaultOrderId;
}
},
mounted() {
// Route parameters also work: /user-profile?userId=789
// {userId} will use 789 from URL, or fall back to data() value of 123
}
};Event Handlers
<form action="/api/subscribe" method="POST"
data-success="subscriptionSuccess" data-error="subscriptionError">
<input type="email" name="email" required>
<button type="submit">Subscribe</button>
</form>export default {
methods: {
subscriptionSuccess(response) { this.$toast('Success!', 'success'); },
subscriptionError(error) { this.$toast('Failed!', 'error'); }
}
};Form Options
<form action="/api/resource/{id}" method="POST"
data-success="handleSuccess" data-error="handleError"
data-redirect="/success" data-confirm="Sure?"
enctype="multipart/form-data">
<input name="title" required>
<input type="file" name="file" accept=".pdf">
<button type="submit">Submit</button>
</form>Authentication Integration
<!-- Auth tokens automatically included for authenticated users -->
<form action="/api/protected/resource" method="POST">
<input name="data" required>
<button type="submit">Save</button>
</form>
<!-- Authorization: Bearer <token> header added automatically -->Form Validation
<!-- HTML5 + custom validation -->
<form action="/api/register" method="POST">
<input type="email" name="email" required pattern="...">
<input type="password" name="password" minlength="8" required>
<button type="submit">Register</button>
</form>Real-World Form Examples
<!-- User profile with dynamic parameters -->
<form action="/api/users/{userId}" method="PUT" data-success="profileUpdated">
<input name="firstName" required>
<button type="submit">Update</button>
</form>
<!-- Order management -->
<form action="/api/orders/{orderId}/status" method="PUT">
<select name="status" required>
<option value="pending">Pending</option>
<option value="shipped">Shipped</option>
</select>
<button type="submit">Update</button>
</form>Form Handling Advantages
- ✅ Zero Setup - Just add
actionattribute vs manual event handlers - ✅ Variable Parameters -
{userId}template syntax vs manual interpolation - ✅ Auto Authentication - Tokens injected automatically
- ✅ File Uploads - Automatic multipart support
- ✅ Built-in Validation - HTML5 + custom functions
Code Comparison
Traditional: 30+ lines of boilerplate for forms, API calls, loading states
ViewLogic: 5 lines with action attribute + callback method
Result: 80% less code, more features included
🔗 Query-Based Parameter System: Revolutionary Simplicity
ViewLogic Router's Query-Based Parameter System is a key feature that eliminates routing complexity:
Philosophy: Everything is query-based - no complex path parameters like /users/:id. Just simple, clean URLs: /users?id=123.
Revolutionary Benefits
- 📍 Simple URLs:
/product?id=123&category=electronics(clear and readable) - 🎯 Consistent Access: Always use
this.getParam('id')- never mix path/query paradigms - ⚡ No Route Configuration: No complex route definitions or parameter mappings needed
- 🔍 SEO Friendly: Descriptive parameter names make URLs self-documenting
- 🌐 Universal Compatibility: Query parameters work everywhere - no framework lock-in
Simple Usage Example
// Navigate - simple and intuitive
this.navigateTo('products', { id: 123, category: 'electronics' });
// → /products?id=123&category=electronics
// Access parameters - always the same way
export default {
mounted() {
const id = this.getParam('id'); // Get parameter
const category = this.getParam('category', 'all'); // With default
const allParams = this.getParams(); // Get all parameters
}
};Why Query-Based is Revolutionary
Traditional Routers: Complex path parameters (/users/:id/posts/:postId) require route configuration, parameter extraction logic, and mixed paradigms.
ViewLogic Router: Simple query parameters (/users?id=123&postId=456) work universally with consistent getParam() access.
🛡️ Error Handling
Built-in comprehensive error handling with automatic 404 detection, graceful component loading failures, and parameter validation with fallbacks.
