Creating a CRM Website Using React JS: A Step-by-Step Guide to Building a CRM Website in React JS

In this tutorial, we will learn how to create a CRM website using React JS. CRM stands for Customer Relationship Management, and it is a system that helps businesses manage their interactions with customers and potential customers. React JS is a popular JavaScript library for building user interfaces, and it is widely used in web development projects.

To get started with this project, make sure you have Node.js installed on your computer. You can download Node.js from the official website (https://nodejs.org/).

Step 1: Create a New React Project
To create a new React project, open your terminal and run the following commands:

npx create-react-app crm-website
cd crm-website

This will create a new React project called "crm-website" in your current directory.

Step 2: Install Additional Dependencies
Next, we need to install some additional dependencies for our project. Run the following commands in your terminal:

npm install react-router-dom
npm install axios

The react-router-dom package is used for handling routing in React applications, and the axios package is used for making API calls.

Step 3: Create Components
In the src folder of your project, create a new folder called components. Inside this folder, create the following components:

• Header.js: This component will render the header of the CRM website.
• Sidebar.js: This component will render the sidebar of the CRM website.
• Customers.js: This component will render the list of customers.
• CustomerDetail.js: This component will render the details of a specific customer.

Step 4: Define Routes
In the src folder, create a new file called App.js. In this file, define the routes for your CRM website using the react-router-dom package. Here’s an example:

import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import Header from './components/Header';
import Sidebar from './components/Sidebar';
import Customers from './components/Customers';
import CustomerDetail from './components/CustomerDetail';

function App() {
  return (
    <Router>
      <div>
        <Header />
        <div className="main">
          <Sidebar />
          <Switch>
            <Route exact path="/" component={Customers} />
            <Route path="/customer/:id" component={CustomerDetail} />
          </Switch>
        </div>
      </div>
    </Router>
  );
}

export default App;

Step 5: Fetch Data from API
In the Customers.js component, we will fetch the list of customers from an API using the axios package. Here’s an example:

import React, { useState, useEffect } from 'react';
import axios from 'axios';

const Customers = () => {
  const [customers, setCustomers] = useState([]);

  useEffect(() => {
    axios.get('https://api.example.com/customers')
      .then(response => {
        setCustomers(response.data);
      })
      .catch(error => {
        console.log(error);
      });
  }, []);

  return (
    <div>
      <h1>Customers</h1>
      <ul>
        {customers.map(customer => (
          <li key={customer.id}>{customer.name}</li>
        ))}
      </ul>
    </div>
  );
};

export default Customers;

Step 6: Display Customer Detail
In the CustomerDetail.js component, we will display the details of a specific customer. Here’s an example:

import React, { useState, useEffect } from 'react';
import { useParams } from 'react-router-dom';
import axios from 'axios';

const CustomerDetail = () => {
  const { id } = useParams();
  const [customer, setCustomer] = useState(null);

  useEffect(() => {
    axios.get(`https://api.example.com/customers/${id}`)
      .then(response => {
        setCustomer(response.data);
      })
      .catch(error => {
        console.log(error);
      });
  }, [id]);

  if (!customer) {
    return <div>Loading...</div>;
  }

  return (
    <div>
      <h1>{customer.name}</h1>
      <p>{customer.email}</p>
    </div>
  );
};

export default CustomerDetail;

Step 7: Run Your Project
To run your project, go back to your terminal and run the following command:

npm start

This will start a development server and open your CRM website in a new browser window. You can now navigate between the list of customers and the details of each customer using the routes we defined earlier.

That’s it! You have successfully created a CRM website using React JS. Feel free to customize the website further and add more features as needed. Happy coding!
