Frontend Architecture & API Integration

Frontend Architecture & API Integration

Our frontend is a Single Page Application (SPA) built with Vue.js. We use a modular structure where every page and component encapsulates its own HTML, CSS, and JavaScript logic.


1. Directory Structure & Organization

We separate the code based on its "responsibility" in the app.

Directory

Purpose

src/views/

The main page containers. These are "Smart" components that usually handle data fetching for a whole page (e.g., HomeView.vue).

src/components/

Reusable UI sections. These are "Dumb" or "Presentational" components (e.g., HeroSection.vue, FooterSection.vue).

src/components/admin/

Specialized management modules for the Admin Dashboard. These handle the CRUD logic for news, teams, and members.

src/services/

The API layer. All communication with the Spring Boot backend happens here.

src/router/

The navigation logic. Maps URLs to specific Views.

2. Routing (Adding New Pages)

// src/router/index.js
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: "/",
      name: "home",
      component: HomeView,
    },
    // Add new routes here
  ]
})

3. Communication with Backend (API Service)

We never make direct fetch or axios calls inside a .vue component. Instead, we use a centralized service layer in src/services/api.js. This allows us to manage global headers, authentication tokens, and base URLs in one place.

Step 1: Register the API Endpoint

export const aboutUsAPI = {
  get: () => apiRequest("/organization"),
  update: (id, data) =>
    apiRequest(`/organization/${id}`, {
      method: "PUT",
      body: JSON.stringify(data),
    }),
};

Step 2: Use the API in a Component

import { aboutUsAPI } from '@/services/api';

const fetchOrganization = async () => {
  try {
    const data = await aboutUsAPI.get();
    // Do something with data...
  } catch (err) {
    console.error("API Error:", err);
  }
};

4. Admin Panel Architecture

The Admin Panel follows a "Manager" pattern. The AdminView.vue acts as the main wrapper, while the actual editing tools are found in src/components/admin/.

  • Managers: Components like NewsManager.vue or EventsManager.vue contain the forms and logic needed to edit content.
  • Data Flow: Typically, a Manager fetches data on mount, allows the user to edit it, and sends a PUT or POST request back through the services/api.js layer.
