Part 2: Database for grocery store & tests

The part-2 folder contains data and queries to set up a grocery store database with tables for items, orders, and shoppers:

With postgres, use the queries from schema.sql to set up the database and load-data.sql to load the data from groceries.csv into the items table and insert data on shoppers and orders into those respective tables.

The database.js file contains functions that return the result of pg-promise queries on the grocery_store database.

The test folder (which is outside of part-2) contains Mocha + Chai tests of some pg-promise functions that query the database. Type npm test in the Terminal to run them.

Part 3: Web Interface for grocery store

The part-3 folder contains HTML, CSS and JS files for a front-end only website where one can add grocery items into a cart that automatically sums the prices as items are added. Just open grocer.html in a browser to try it out.
