Getting Started

To get the E-Commerce API App up and running on your local machine, follow these instructions.

Prerequisites

• Node.js: Ensure Node.js is installed on your machine. You can download it from Node.js official site.
• MongoDB: A running instance of MongoDB. You can use MongoDB Atlas for a cloud-based solution or install MongoDB locally.

Installation

1. Clone the Repository:

   git clone https://github.com/AthulKM/ECommerceAPIsApp.git cd ECommerceAPIsApp

2. Install Dependencies:

   npm install

3. Setup Environment Variables:

   Create a .env file in the root directory and add the following variables:

   MONGO_URI=your_mongodb_connection_string SECRET_KEY=your_jwt_secret_key PORT=3001

   Replace your_mongodb_connection_string with your MongoDB connection string and your_jwt_secret_key with a secret key for JWT.

4. Run the Application:

   npm start

   The server will start on http://localhost:3001 (or the port specified in .env).

Testing

To test the application:

Run Tests:

Install the testing dependencies if not already installed:

npm install --save-dev mocha chai

• Run the test suite:

npm test

Ensure your MongoDB instance is running, and adjust configurations if necessary.

Using Postman:

• Install Postman:

Download and install Postman from Postman official site.

• Import Postman Collection:

If available, import a Postman collection for the API into Postman. This collection will contain pre-configured requests for various API endpoints.

• Test Endpoints:

Use Postman to send requests to the API endpoints and verify that the responses are as expected. You can test all the endpoints listed under the API Endpoints section.
