Create React Project

In order create react project, first we should install Node.js. Download the Node.js from the below link and install on your system

https://nodejs.org/en/download/

Once Node.js is installed on your system, you can verify it by executing the below command

node -v

To create new react project, we can use create-react-app library. Open the command prompt, enter the following command

npx create-react-app my-app

This will create react starter project. Next open the project in any text editor

Install axios library

On the root of the project, enter the following command to install axios library

npm install axios

• Axios is a simple promise based HTTP client for the browser and node.js.
• Axios provides a simple to use library in a small package with a very extensible interface.

Install React Router DOM library

On the root of the project, enter the following command to install react-router-dom library

npm install react-router-dom

Configure axios library

Inside src folder, create http-common.js file and add the following content –

import axios from "axios";

export default axios.create({
    baseURL: 'http://localhost:8080/api/v1',
    headers: {
        'Content-Type': 'application/json'
    }
});

Create Employee Service

Inside src/services folder, create employee.service.js file and add the following content –

import httpClient from "../http-common";

const getAll = () => {
    return httpClient.get('/employees');
}

export default { getAll };

Create EmployeeList Component

Create EmployeesList.js inside src/components folder and add the following content

import { useEffect, useState } from 'react';
import employeeService from '../services/employee.service';

const EmployeeList = () => {

  const [employees, setEmployees] = useState([]);

  useEffect(() => {
    employeeService.getAll()
      .then(response => {
        console.log('Printing employees data', response.data);
        setEmployees(response.data);
      })
      .catch(error => {
        console.log('Something went wrong', error);
      })    
  }, []);

  return (
    <div>
      <h3>List of Employees</h3>
      <div>
        <table border="1">
          <tr>
            <th>Name</th>
            <th>Location</th>
            <th>Department</th>
          </tr>
          {
            employees.map(employee => (
              <tr key={employee.id}>
                <td>{employee.name}</td>
                <td>{employee.location}</td>
                <td>{employee.department}</td>
              </tr>
            ))
          }
        </table>
      </div>
    </div>
  );
}

export default EmployeeList;

Create NotFound Component

Create NotFound.js inside src/components folder and add the following content

const NotFound = () => {
    return (
        <div>
            <p>The page you are looking is not yet developed.</p>
        </div>
    );
}
 
export default NotFound;

Configure React Router

Open App.js and add the following content

import { BrowserRouter, Switch, Route } from 'react-router-dom';
import EmployeeList from './components/EmployeesList';
import NotFound from './components/NotFound';

function App() {
  return (
    <BrowserRouter>
      <div>
        <div>
          <Switch>
            <Route exact path="/" component={EmployeeList} />
            <Route path="*" component={NotFound} />
          </Switch>
        </div>
      </div>
    </BrowserRouter>
  );
}


export default App;

Run the React app

On the root of the project, open the command prompt, execute the following command

npm start

This will run the application on the port, localhost:3000

Now try navigate to the route which is not configured localhost:3000/abc

In the next part of this series, we will learn how to apply Bootstrap styling to the react application.
