• Component Libraries like MUI or TailwindCSS for professional UI.

2. Backend (Optional but Recommended for Full Stack ERP Project):

• Node.js + Express.js for REST APIs.
• MongoDB for storing business and module data.

3. Version Control & Hosting:

• GitHub to store and share your code.
• Vercel (or Netlify) to deploy your app live.

This full-stack setup ensures your ERP app is scalable, secure, and easy to maintain.

Step-by-Step Guide to Build ERP System in ReactJS

If you’re looking to build an ERP with React, you are at the right place.

Here we will walk you through every step, from project setup to creating real ERP modules with clean code and responsive UI.

Whether you’re a developer, startup founder, or business owner, this guide will help you create a professional ERP system in ReactJS.

Step 1: Project Setup (React App + Folder Structure)

Let’s begin by setting up our ERP project using Vite (much faster than Create React App):

          
                npm create vite@latest react-erp-system --template react
                cd react-erp-system
                npm install
                npm run dev
          
        

Install essential packages:

          
                npm install react-router-dom axios
          
        

Recommended folder structure:

          
                /src
                /components
                /pages
                /modules
                    /Inventory
                    /Employees
                    /CRM
                /context
                /services
                /utils
                App.jsx
                main.jsx
          
        

Step 2: Creating the ERP Dashboard UI in ReactJS

An ERP system needs a sidebar, top navbar, and a main content area. Let’s create a basic layout:

components/Layout.jsx

          
                import Sidebar from './Sidebar';
                import Topbar from './Topbar';
                
                const Layout = ({ children }) => (
                <div className="flex h-screen">
                    <Sidebar />
                    <div className="flex-1 flex flex-col">
                    <Topbar />
                    <main className="p-4 overflow-y-auto">{children}</main>
                    </div>
                </div>
                );

                export default Layout;
          
        

Use TailwindCSS or MUI to style the components for a clean UI.

Step 3: Building Key ERP Modules (with Code Examples)

1. Employee Management Module

modules/Employees/EmployeeList.jsx

          
                import { useEffect, useState } from 'react';
                import axios from 'axios';
                
                const EmployeeList = () => {
                const [employees, setEmployees] = useState([]);
                
                useEffect(() => {
                    axios.get('/api/employees').then(res => setEmployees(res.data));
                }, []);
                
                return (
                    <div>
                    <h2 className="text-xl font-bold mb-4">Employees</h2>
                    <ul>
                        {employees.map(emp => (
                        <li key={emp.id}>{emp.name} - {emp.position}</li>
                        ))}
                    </ul>
                    </div>
                );
                };
                
                export default EmployeeList;
          
        

2. Inventory Management Module

modules/Inventory/InventoryList.jsx

          
                const items = [
                { id: 1, name: 'Laptop', quantity: 12 },
                { id: 2, name: 'Monitor', quantity: 8 }
                ];
                
                const InventoryList = () => (
                <div>
                    <h2 className="text-xl font-bold mb-4">Inventory</h2>
                    <table className="table-auto w-full">
                    <thead>
                        <tr>
                        <th>Name</th>
                        <th>Quantity</th>
                        </tr>
                    </thead>
                    <tbody>
                        {items.map(item => (
                        <tr key={item.id}>
                            <td>{item.name}</td>
                            <td>{item.quantity}</td>
                        </tr>
                        ))}
                    </tbody>
                    </table>
                </div>
                );
                
                export default InventoryList;

          
        

3. CRM / Client Records Module

modules/CRM/Clients.jsx

          
                const clients = [
                    { id: 1, name: 'Acme Corp', contact: 'acme@example.com' },
                    { id: 2, name: 'Globex', contact: 'info@globex.com' }
                ];
                    
                    const Clients = () => (
                    <div>
                        <h2 className="text-xl font-bold mb-4">Clients</h2>
                        <ul>
                        {clients.map(client => (
                            <li key={client.id}>{client.name} – {client.contact}</li>
                        ))}
                        </ul>
                    </div>
                    );
                export default Clients;
          
        

Step 4: State Management (Context API or Redux)

For small to medium projects, Context API works great. Here’s a basic setup:

context/UserContext.jsx

          
                import { createContext, useContext, useState } from 'react';

                const UserContext = createContext();
                
                export const useUser = () => useContext(UserContext);
                
                export const UserProvider = ({ children }) => {
                const [user, setUser] = useState(null);
                
                return (
                    <UserContext.Provider value={{ user, setUser }}>
                    {children}
                    </UserContext.Provider>
                );
                };

          
        

Wrap <App /> with UserProvider in main.jsx.

Step 5: Backend Integration (If Applicable)

If you want to make this a full-stack ERP system, connect to a backend using Node.js + Express + MongoDB.

Sample Axios API Call:

          
                axios.get('https://yourdomain.com/api/employees')
                .then(res => console.log(res.data))
                .catch(err => console.error(err));
          
        

Use REST APIs for CRUD operations on each module (Employee, Inventory, etc.).

Step 6: Authentication & Role-Based Access

Use React Router with role-checking logic.

utils/PrivateRoute.jsx

          
                import { Navigate } from 'react-router-dom';
                import { useUser } from '../context/UserContext';
                
                const PrivateRoute = ({ children, role }) => {
                const { user } = useUser();
                if (!user || user.role !== role) return <Navigate to="/login" />;
                return children;
                };
                
                export default PrivateRoute;

          
        

Apply this to admin-only routes for your ERP modules.

Step 7: UI Polishing and Responsive Design

Use TailwindCSS, Flexbox, and Grid to ensure your ERP UI is fully responsive.

Example:

          
                <div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
                {/* ERP Cards or Module Boxes */}
                </div>
          
        

Ensure:

• Dashboard scales on tablets & mobiles.
• Forms and tables look clean.
• Dark mode support (optional).

What Are the Common Issues & Troubleshooting Tips?

Even experienced developers run into challenges while building a full ERP React project. Here are some of the most common issues and how to solve them:

• Build Errors: If you’re using multiple packages, make sure your dependencies are compatible and updated. React version mismatches can often cause build issues.
• Component Structure Confusion: ERP systems require a clean folder structure. Separate your modules (HR, Inventory, etc.) into their components and containers for better maintainability.
• Authentication & Routing Fixes: Use libraries like React Router and implement role-based access to secure module-level routes. Many developers face issues with private routing in admin dashboards.
