1.4.1. Frontend Development

Start by building your React components based on your wireframes. For example, for a task manager app, you might build:

• TaskList: Displays all tasks.
• TaskItem: Displays individual tasks, with options to edit or delete.
• LoginPage: User login screen.

In this chunk, we focus on creating the visual parts of the application using React components. Components are reusable pieces of code that define how a particular section of your user interface should look and behave. For example, the 'TaskList' component is responsible for showing a list of all tasks, while the 'TaskItem' component is designed to show each task individually and give users options to modify or remove it. The 'LoginPage' is dedicated to allowing users to log into the application securely, ensuring only authenticated users can access the main features of the app.

Think of building UI components like laying bricks to build a house. Each brick (or component) represents a single feature, such as displaying tasks or user login, and when you put them together properly, they create a functional and attractive house (or application). Just as you would choose specific types of bricks for different parts of a house, you select different components for various functionalities in your app.

Use Axios to communicate with your backend API. For instance:

import axios from 'axios';
const fetchTasks = async () => {
  const response = await axios.get('http://localhost:5000/api/tasks');
  return response.data;
};

This chunk introduces how to connect your frontend application to your backend server using Axios, which is a promise-based HTTP client for the browser and Node.js. The example shows an asynchronous function called 'fetchTasks' that sends a GET request to the backend API endpoint that is supposed to return all tasks. The response data, which is the task information, is then returned so it can be displayed in the user interface.

Imagine you are ordering a pizza from a restaurant. When you call or go online (this is like making an API request), you place your order (specify what tasks you want), and then the restaurant prepares your pizza (the server processes your request). Finally, you receive your order (the response from the server) that you can enjoy (display in your app).

Use React Router to handle navigation between pages like Login, Dashboard, Task Management, etc.

Routing in a web application refers to how different pages or views are displayed based on the URL. React Router is a library that facilitates this process in React applications. By implementing routing, users can navigate between different parts of your application without reloading the entire page. For instance, when a user clicks on the 'Task Management' link, React Router will show the component associated with task management without refreshing the webpage.

Think of a website as a multi-room house. Each room serves a different purpose, like a living room for relaxation or an office for work. Routing is like the doors in your house: they allow you to move from one room to another (or from one page to another) smoothly without having to leave your house each time to walk to a new space.
