BooksApi

To start your Phoenix server:

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Start Phoenix endpoint with mix phx.server

Now you can visit localhost:4000 from your browser.

Guidelines

Use the Phoenix framework to build an API REST to manage (create, edit, delete) Books and Authors database with Ecto, partial authentication using HTTP auth-basic capabilities against the database, and error management.

Database

• MySQL

Tables

Books (uuid, name, description)

• Authors (uuid, firstname, lastname)
• N-M relation books and authors
• Users (uuid, username, password)
• Methods (uuid, function, method)
• N-M relation users and methods

REST methods to implement (require auth for everything that is not a GET):

• GET
• POST
• PUT
• PATCH
• DELETE

Errors/HTTP response codes to handle

• 200: everything went fine
• 201: a POST went fine
• 400: bad request, for example, wrong data sent during a POST
• 401: wrong credentials or credentials needed but not provided
• 403: credentials are correct but user not allowed
• 404: not found
• 410: resource not found, for example after requesting it by doing a GET
• 500: generic error
• 503: database not available
