Shopify Production Intern Challenge

Introduction

This project is for the Fall 2022 Shopify Production Engineer Intern Challenge. It is an inventory tracking web application capable of performing the functional requirements listed below.

Project Layout

This application was built with the Next.js framework. Therefore, files inside the pages/api folder are mapped to /api/* REST endpoints. For example, the HTTP handler in pages/api/v1/items/[id].ts maps to /api/v1/items/{id}. The HTTP handler in pages/api/v1/items/index.ts maps to /api/v1/items. The code for each HTTP handler can be seen in pages/api.

The application talks to an SQLite database on the backend. The database file is prisma/dev.db. HTTP handlers call functions inside of repo/db to perform database operations.

Similarly, on the frontend, Next.js maps React components in pages/ to webpages, excluding files in /pages/api. For example, pages/index.tsx maps to the root index, /. The component inside of pages/items/edit/[id].tsx maps to /items/edit/{id}, where {id} is a valid ID for an inventory item. React components inside of pages/ call functions inside of repo/api to perform HTTP requests to the backend.

Functional Requirements and Instructions

Create inventory items:
- From the index page, click on the Create item link.
Edit inventory items:
- From the index page, click on the Edit link beside an item you want to edit.
Delete inventory items:
- From the index page, click on the Edit link beside an item you want to delete.
- On the edit page, click on the Delete item button.
View a list of inventory items:
- The index page displays a list of all items.
Each inventory item should be associated with a city where the item is stored:
- From the index page, a list of items are shown in addition to the city the item it is assigned.
- When editing an item, you also have the ability to change its city.
The list of items in the inventory must include the city and a simple textual description of the current weather:
- From the index page, the list of items contain their assigned city and the current weather for that city.
Ability to create “shipments” and assign inventory to the shipment, and adjust inventory appropriately:
- From the index page, click on the Create shipment link.
- Click on the plus button [ + ] beside any of the "Available items" to add it into the "Shipping Items" cart.
- More than one item can be added to the cart. Once at least one item is added to the "Shipping Items" cart, click on the Process Shipment button.
- Going back to the index page, the updated quantities are shown.
