How to create backend CRM using React JS


Developing a backend CRM using React.js involves constructing a React frontend interface that interacts with a backend server such as Laravel, Node.js, or Django through APIs. React takes care of the user interface and client-side logic while the backend takes responsibility for authentication and business logic as well as database operations.

 

Create a Vite React Project

  • Creates a new Vite project named my-app using the React template.

  • Vite is a fast build tool optimized for modern front-end development.

React Project Structure

  • Folder structure for your React project

Root-Level Files

  • App.jsx – Main component that contains the routes and wraps the whole application.

  • App.css – CSS file for global styles related to the App component.

  • index.css – General global styles used across the app.

  • main.jsx – Entry point of the React app where the root component is rendered (typically wraps App.jsx with providers like BrowserRouter).

    Example:

API Service - Interceptor

  • Axios.jsx – Custom Axios instance configuration (base URL, headers, interceptors, etc.)

    Example:

Authorization - auth

  • AuthContext.jsx – Provides authentication context (user state, login/logout logic).

  • ProtectedRoute.jsx – Route wrapper to restrict access based on login or roles.


    Example:

Components

  • Navbar.jsx – Top navigation bar UI.

  • Sidebar.jsx – Side menu UI, likely with links to pages based on roles.

  • Footer.jsx – App footer UI component.

Roles page

  • EditUser.jsx – Form to update user details.

  • UserList.jsx – List of users with management actions

Pages - Dashboard, Login

  • Dashboard.jsx – Main landing page after login; may include metrics or summaries.
