Programming Exercise: Shopping Cart

The goal of this programming exercise is to implement the server-side functionality related to working with a shopping cart. All data is read from file and accessed via in-memory collections. For simplicity, there is no relational or document database. The following services have stub methods that need to be implemented:

• src/services/coupons.js
• src/services/products.js
• src/services/shopping-cart.js

All of the tests for a basic shopping cart have already been written following the pattern of Test Driven Development (TDD). Please review the tests in test/test.js to get a better understanding of the expected functionality.

Setup

1. Install NodeJS
2. Install Dependencies

npm install

Run Tests

npm test

Run Server

npm start

Goals

• Fork this repo
• Implement all functions that are marked with // TODO: Implement Review existing comments and tests
• Make changes until all tests pass

Bonus Points

• Create a REST API for the shopping cart CRUD operations. Assume that each shopping cart is associated with a unique session ID that will be sent as a cookie. The file server.js has the code in place to launch a simple express server, but you can also choose to use a different server/router as well. For clarity, you may wish to provide a sample response for each REST API route.

Additional Notes

• Even though a real database is not being used, most of the CRUD functions for products, coupons, and shopping carts are written such that they can be asynchronous. To minimize dependencies, the Node.js-style callback convention was chosen instead of promises.
