Assignment

Design the data model for a recipe book application, then use Knex migrations and seeding functionality to build a SQLite3 database based on the model and seed it with test data.

The requirements for the system, as stated by the client are:

have a way to manage recipes.
have a way to manage ingredients.
a recipe could have more than one ingredient and the same ingredient can be used in multiple recipes. Examples are "cup of corn flour" or "gram of butter".
when saving the ingredients for a recipe capture the quantity required for that ingredient as a floating number.
have a way to save step by step instructions for preparing a recipe.

Hint: Before writing any code, write out all desired tables in the data model and determine all relationships between tables.

Migrations and Seeds

Write a migration file that creates all tables necessary to model this data
Write seed files to populate the tables with test data. Hint: Keep your recipes very simple or this step could become extremely time consuming.

Data Access

In addition to the migrations and seeding scripts, write a data access file that exports an object with the following functions:

getRecipes(): should return a list of all recipes in the database.
getShoppingList(recipe_id): should return a list of all ingredients and quantities for a given recipe
getInstructions(recipe_id): should return a list of step by step instructions for preparing a recipe

Organize and name your files anyway you see fit.

Stretch Problem

Build the following endpoints. Write any additional data access helpers as needed.

GET /api/recipes/: all recipes (without details about ingredients or steps)
GET /api/recipes/:id/shoppingList: a list of ingredients and quantites for a single recipe
GET /api/recipes/:id/instructions: a correctly ordered list of how to prepare a single recipe
GET /api/ingredients/:id/recipes: all recipes in the system that utilize a single ingredient
