Single-Page Applications

1. Introduction

2. Key Concepts

• Dynamic Content Loading
• AJAX (Asynchronous JavaScript and XML)
• Client-Side Routing
• History API

3. Architecture

SPAs typically rely on a frontend framework (like React, Angular, or Vue.js) and utilize APIs to communicate with the backend. The architecture usually follows a Model-View-ViewModel (MVVM) or Model-View-Controller (MVC) pattern.

4. Client-Side Routing

Client-side routing allows users to navigate through the application without refreshing the page. This is typically handled by libraries or frameworks.

        const routes = [
            { path: '/', component: Home },
            { path: '/about', component: About },
            { path: '/contact', component: Contact },
        ];

        function Router() {
            const currentPath = window.location.pathname;
            const currentRoute = routes.find(route => route.path === currentPath);
            return currentRoute ? currentRoute.component() : NotFound();
        }
        

5. Best Practices

1. Use lazy loading for components to improve initial load times.
2. Implement a robust state management solution (e.g., Redux or Vuex).
3. Optimize performance by minimizing re-renders.
4. Ensure accessibility with proper ARIA roles.
5. Maintain SEO with server-side rendering when necessary.
