Node Project Four

Introduction

In this Project, you will write an API that can be used to manage Cars stored in a Relational Database and You will also write some SQL statements in the queries.sql file.

Instructions

Minimum Viable Product

Build a RESTful API for an "cars" resource. The client for this API is a car dealer. Write the statements mentioned below as a SQL Query using the w3schools website.

Cars Schema

The critical information for each car is the vin, make, model, and mileage. They also track transmission type (manual, automatic...) and status of the title (clean, salvage...), but this information is not always immediately known. Write the "up" and "down" functions inside the data/migrations/01-make_cars_table.js migration file to satisfy the following schema:

field	data type	metadata
id	unsigned integer	primary key, auto-increments, generated by database
vin	string	required, unique
make	string	required
model	string	required
mileage	numeric	required
title	string	optional
transmission	string	optional

Write Model Functions

• Write the following db access functions inside api/cars/cars-model.js using Knex:

  • getAll resolves to an array of car records (or an empty array)
  • getById resolves to a car record by the given id
  • create resolves to the newly created car record

Write a Cars API

• Write CRUD for the cars resource inside api/cars/cars-router.js :

  • [GET] /api/cars returns an array of cars sorted by id (or an empty array if there aren't any).
  • [GET] /api/cars/:id returns a car by the given id.
  • [POST] /api/cars returns the created car.

• Manually test your endpoints with a REST client like Insomnia or Postman to check they are working as expected.

Write Basic SQL Queries

Visit SQL Try Editor at W3Schools.com using Chrome and build the queries below. Once they work copy them to the queries.sql file at the root of the project.

• Find all customers with postal code 1010. Returns 3 records.
• Find the phone number for the supplier with the id 11. Should be [phone].
• List first 10 orders placed, sorted descending by the order date. The order with date 1997-02-12 should be at the top.
• Find all customers that live in London, Madrid, or Brazil. Returns 18 records.
• Add a customer record for "Yusuf Ali", the contact name is "Yusuf Ali" the address is "123 Somali Street" in "Somalia", postal code "111" and the country is "Somalia".
• Update Yusuf Ali record so that the postal code changes to "11122".

Clicking the Restore Database button in the page will repopulate the database with the original data and discard all changes you have made.

Task 3: Stretch Problems

• Add seed data to the database using knex seeds
• Add [PUT] and [DELETE] operations to your API.
• Write a schema file for a sales table. This table should track information on the sale of each car. You may wish to research foreign keys in order to link each sale to the entry in cars which sold.
