# PVL Assessment Demo

As part of the PVL hiring assessment, I've developed this MERN stack application, showcasing my skills in building a full-stack web application using the MERN (MongoDB, Express, React, Node.js) stack. It has been a valuable learning experience, and I'm excited to present my work.

## Getting Started

To run this project locally for development and testing, follow these steps:

### Prerequisites

Make sure your computer has the following software installed:

- [Node.js](https://nodejs.org/): JavaScript runtime environment
- [npm](https://www.npmjs.com/): Node Package Manager

### Installation

1. Clone this repository to your local machine:

   ```bash
   git clone https://github.com/yourusername/PVL_Assessment_Demo.git
   ```

2. Navigate to the project's root folder:

   cd PVL_Assessment_Demo

3. Install the server dependencies:

   npm install

4. Navigate to the client folder:

   cd client

5. Install the client dependencies:

   npm install

Configuration

Before running the application, you need to configure your MongoDB connection settings as I have not allowed external IP's for database acsess. For the sake of the assessment, I will keep the port open as I do not know the IP that will be accessing the DB. It is not recommended usually as it is a major security concern.

Running the Application

1. Start the backend server from the project's root folder:

   node app.js

2. Run the frontend development server from inside the client folder:

   cd client
   npm start

You can access the application at http://localhost:3000/.

Project Structure

• The backend code is located in the root folder and is built with Express.js. It connects to a MongoDB database hosted on MongoDB Atlas.
• The frontend code resides in the client folder and is developed using React.

Deployment

This project is ready for deployment on cloud platforms or web hosting services. Don't forget to update your MongoDB connection string for the production environment.

Running Tests

To run test cases for the Node.js application using Mocha, follow these steps:

1. Open a terminal.

2. Navigate to the root folder of your project using the cd command:

   cd /path/to/your/project

3. Run the Mocha tests using the following command:

   .\node_modules\.bin\mocha .\test\app.test.js

   This command runs the Mocha tests located in the app.test.js file within the test folder of the project.

4. You can modify the formData object in the app.test.js file to test different data scenarios. Update the data as needed for your test cases.

Testing is essential for ensuring the reliability of your code.

Built With

• MongoDB Atlas: Cloud-hosted MongoDB database
• Express.js: Web application framework for Node.js
• React: JavaScript library for building user interfaces
• Node.js: JavaScript runtime environment
