Investoo Tech Challenge

The aim of this challenge is to introduce query parameter filtering to our API. We'd then like to see this visualised within the frontend, so that internal teams can preview which offers will show depending on the filters they apply.

The code you have been sent is a heavily stripped down replication of our monolith API, and the console that consumes it. Inside, you'll see an endpoint that returns all offers from the database. We'd like to be able to filter data coming back from the API, depending on the context in which it's requested.

For example, we may only want to return offers where the minDeposit property has a value higher than 100. Or only show offers that support BTC.

Once you've done this, please take a look at the below questions and have a go at answering them.

Please, do not spend hours on this challenge. If you've spent more than 2 hours working on this, I'd much prefer you to stop where you are, and write some notes detailing what your next steps would have been. No one likes a long test!

Requirements

Backend

Implement query parameter filtering for your API. Think about where you'd perform this filtering, it's syntax, and usability. Below are some examples, but you don't need to implement all of these!
- property is greater/less than/equal to X
- property has date earlier/later than X
- property contains/does not contain X (if the property is an array)
- property is/is not set
- property is "like" (similar to .includes)
Refactor this project in whatever way you'd prefer
Write test(s) for this filtering system

Frontend

Implement a simple preview tool, that has some form fields to filter offers from your API
Consider the UX of this tool. We use Vuetify to craft our UI

Questions

If you'd had more time, what you have changed?
How would you improve the performance of this API?

Project Setup frontend

Go to the frontend folder cd frontend/
Install dependencies npm i
Run watcher npm run serve

Project Setup backend

Install docker if you haven't already got it
Go into the backend folder cd backend/
Build, create, start, and attach to containers docker-compose up -d
Install dependencies docker-compose run --rm offers npm i
Run migrations docker-compose run --rm offers npm run knex:migrate:latest
Run seeds docker-compose run --rm offers npm run knex:seed
Expose App logs docker-compose logs -f
The API is exposed on port 3000 by default
