DEV setup

In the root directory, create an .env file with the PostgreSQL URL DATABASE_URL=postgres://url_to_whatever_database_you_have_access

To build the database npm run db_build init

In browser open localhost:1234

Requirements

Simple web app with a node server and a database
Database hosted on Heroku, or locally
Build script for your database
Security concerns appropriately considered (you must protect against script injections!)
Content dynamic, but DOM manipulation kept to a minimum
Mobile-first design
test your server routes with supertest
test your pure functions both server and client side
set up a test database so that you can test your database queries

PROCESS

We spent Wednesday afternoon deciding on our theme which didn't take too much time (after forcing another group to change their plan!)
Then we drew out wireframes so that we had a decided layout from the start
We also drew out the relationships between each module to help decide on our schema
In pairs we built the database and set up the server/handler
On Thursday we had a good basis to begin with the getData and postData files
Then we spent the rest of the day mobbing the set up of the test environment and rest of the postData
After sorting out some problems, we had the rest of the afternoon to finish our styling and adding some extra features

Schema

Architecture

Sorting Hat Function

const sortingHat = answers =>
  answers.reduce(
    (a, b, i, arr) =>
      arr.filter(v => v === a).length >= arr.filter(v => v === b).length
        ? a
        : b,
    null
  );

In this function we find the highest occurring element in the array. In using the reduce() method, i = the current index making it start from the initial value, arr = the source array of selected answers. The function goes through and compares how many answers match to a, creating a new array of the occurrences. It does the same thing for b, and then compares which of those arrays is longer. It repeats the process for every answer until it finds the one that repeats the most and returns the single value.
