# How to Integrate PostgreSQL with Syncfusion React Scheduler using Node.Js

This repository contains a sample full-stack application demonstrating how to synchronize events between PostgreSQL and the Syncfusion React Scheduler component.The Node.js backend handles CRUD operations on Scheduler events using a PostgreSQL database, and the React frontend delivers a modern, responsive scheduler interface for interacting with those events.

## Prerequisites

- Node.js (>= 20.19)
- npm (>= 7.0)
- react (>= 18.0)
- A PostgreSQL Database with Username and Password (create at https://www.postgresql.org/download/)

## Setup

### Cloning the repository
    
- Clone the repository to your local machine

### Backend Setup

### Installation
1. Open a terminal and navigate to the backend folder:
    ```bash
    cd backend
    ```
2. Install dependencies:
    ```bash
    npm install
    ```

### PostgreSql Configuration
- Create a PostgreSQL user with a chosen username ,password and database name.
- In `backend/config/db.config.js` file update the USER ,  PASSWORD and DB as per the database configuration.

```ini
    USER=<your-user-name>
    PASSWORD=<password-for-specific-user>
    DB=<your-Database-name>
    ```               
  **Note:** The default PostgreSQL username is `postgres` unless you have changed it.

### Frontend Setup

### Installation

1. Open the project directory in terminal to install the required packages.

```bash
    npm install
    ```

### Running the Application
1. Open a terminal and navigate to backend folder
      ```bash
    cd backend
    ```
2. Start the backend server:
    ```bash
    node server.js
    ```
3. Server started running on `http://localhost:8080`
4. Open another terminal and start the frontend:
    ```bash
    npm start
    ```
5. Navigate to [`http://localhost:8081`](http://localhost:8081) in your browser.

6. You can perform CRUD operation on the scheduler that will be reflected in the postgreSQL database table.

## Troubleshooting
- **401 Unauthorized**: Check `User`,`Password` and `DB` in `db.config.js` in `backend`.
- **CORS errors**: Ensure frontend calls runs on `localhost:8081`
