Problem Statement - Product​

Ecommerce is the buying and selling of products on the internet. The products that are sold on any e-commerce website are the core of the business. Consumers add products to their shopping carts, pay the amount online and buy the products. Sometimes, at the check-out, a consumer may delete a product from the cart, update the count of the products, etc. The application should be able to handle all the consumer requirements to give them a good shopping experience.

Build a REST API using vanilla JS to manage the product details and add new products, fetch all the products available, fetch a specific product by id, delete a product and update the details of a specific product.

Tasks

• Create a HTTP server to service requests from clients​
• Define all HTTP methods like GET, POST, PUT and DELETE​
• Define routes to​
• Get all the products​
• Get a product by productid​
• Create a new product and post the data​
• Update the details of a specific product​
• Delete a product by productid​
• Test the output in the REST Client Postman​ ​

Instructions

1. Download and unzip the boilerplate code.
2. Run the command npm install to install the dependencies.
3. Open the boilerplate code in VSCode to develop the solution.
4. Write the logic for the application in the productsService.js file in the src folder
5. Write logic to read the request body data in the utils.js file in the src folder
6. Create the server in the app.js file and use the functions of the productsService.js

Running the code

• Execute the npm start command to start the application
• Test all REST end points on POSTMAN

Testing the application

• Run the test scripts available under src/test by giving npm run test command in the terminal to test locally.
• Refactor the solution to ensure all test cases are passing.
• Zip the solution code with the name same as assignment name.
• Upload the zipped solution for submission.
