A simple service for getting all unrated products for a user. He/she can rate a product that has already been purchased and delivered. APIs to get the average rating of the products and user rating for each and every product.
npmnode>= v12.14.0 (will likely work with older versions, but has never been tested)
npm install
npm start will start the application at
http://localhost:8080 (set environment variable PORT
to change the port).
The service can now be called:
$ curl http://localhost:8080/ratings/products -- This will give us the products list that are avaiable in inventory
{"1":{"name":"Apple Mac Pro","description":"Apple laptop Macbook pro 15Inch touch Bar","average_rating":3.6},"2":{"name":"Apple Mac Air","description":"Apple laptop Macbook Air 13Inch","average_rating":0},"3":{"name":"Apple Home","description":"Apple Home with 1TB SDD","average_rating":0}}
$ curl http://localhost:8080/ratings/true -H "user_id:1" -- This will get all products that are already rated by user_id:1
[{"user_id":1,"product_id":1,"rating":3,"name":"Apple Mac Pro","description":"Apple laptop Macbook pro 15Inch touch Bar","average_rating":3.6}]
$ curl http://localhost:8080/ratings/false -H "user_id:1" -- This will get all products that are delivered but not rated by user_id:1
[{"user_id":1,"product_id":2,"rating":0,"name":"Apple Mac Air","description":"Apple laptop Macbook Air 13Inch","average_rating":0},{"user_id":1,"product_id":3,"rating":0,"name":"Apple Home","description":"Apple Home with 1TB SDD","average_rating":0}]%
Tests can be run with npm test.
All tests are colocated with their respective source files in *.spec.js files,
using Jest with default settings.
You do not need to run the application separately to run any tests.
