The goal of this technical task is:

• create an API which supports:
  1. Create of Form Definitions
     • each field in the definition has a “question” and a data type that the answer should adhere to
  2. Submit + Validate Entries
     • form entries should be validated on data field types
  3. Filter on Entries (optional)
• create a frontend in which:
  1. A sigle form definition can be shown
  2. Entries can be submitted based on a form definition
  3. New form definitions can be created (optional)

Backend

You're free to use whatever database solution that you prefer. We provide two projects in this repo:

• one with a postgres setup
• one with a monogodb setup

If you're more comfortable with something else feel free to include it.

Create Form Definitions

To test your implementation; we will create two forms (the service should be able to create an arbitrary number of forms):

• Form 1

  • What is your name? string
  • Where do you live? tuple (lat/lon)
  • How long, in seconds, can you hold your breath? integer

• Form 2

  • Are you interested in crypto? boolean
  • How many different coins have you invested in? integer
  • What was the date you first bought crypto? date
  • How many times, per year, do you buy crypto? integer

Submit + Validate Entries

We will submit the following entries (the entries marked as invalid should throw an error):

• Storybook
• Cypress
