Appointment Scheduling

Motivation

Clients need to be able to schedule an appointment with their trainer through an HTTP API.

Instructions

The client should be able to pick from a list of available times. Appointments for a trainer should not overlap. Appointments are 30 minutes long. Appointments should be scheduled at :00, :30 minutes after the hour during business hours. Business hours are M-F 8am-5pm Pacific Time

Your job is to create an HTTP JSON API written in Go with the following endpoints:

Get a list of available appointment times for a trainer between two dates Parameters: trainer_id starts_at ends_at Returns: list of available appointment times
Post an appointment (as JSON) Fields: trainer_id user_id starts_at ends_at
Get a list of scheduled appointments for a trainer Parameters: trainer_id

appointments.json contains the current list of appointments in this format:

[ { "id": 1 "trainer_id": 1 "user_id": 2, "starts_at": "2019-01-25T09:00:00-08:00", "ends_at": "2019-01-25T09:30:00-08:00" } ]

You can store appointments in this file, a database or any back end storage you prefer.

CURL commands

Create new appointment

curl -X POST -H "Content-Type: application/json" -d '{"user_id": 1,"starts_at": "2020-01-26T11:40:00-08:00"}' "http://localhost:3000/trainers/1/appointments"
