Appointment scheduler API for a psychotherapist's website | Node.js | Express.js | MongoDB | Mongoose

ec-api

Back-end part of the "ec" project

The "ec" project is a Single Page Application created for a psychologist Emilia Cwojdzińska. It was designed to provide the Emilia's customers with information about her areas of expertise, services she offers and - most importantly - a way to book an apointment online and pay for it in advance.

Technologies, frameworks and libraries used on the back end

• node.js
• express
• mongodb
• mongoose (to enforce data validation before saving to mongodb)
• moment (extended with moment-timezone - to stick to Emilia's local time regardless of the customer's timezone)
• dotenv (to use environmental variables locally)
• nodemailer (to send automatic email notifications to Emilia and her customers when an appointment is booked)
• @ingameltd/node-przelewy24 (to implement Przelewy24 online payments)

Setup

These instructions will get you a copy of the project up and running on your local machine.

Prerequisites

You need to have access to a MongoDB database. I recommend trying MongoDB Atlas for free. Please follow instructions on the MongoDB website.

You also need to have a transactional email provider account. I recommend trying Sendinblue.

It is important that you change the text of the confirmation email so that you do not impersonate and misrepresent Emilia and her practition. To do that, modify the object (specifically, its html property) that is an input to transporter.sendMail method which is located in ec-ui/functions/emailSender.js. The contents of the confirmation email are within template literals, in the area of lines 50-120.

Once you have the abovementioned services activated you have to create a file named .env in the main ec-api directory and paste the following code (filled with data of your accounts):

DB_URL=mongodb+srv://admin:<password>@<cluster-name>-icadi.mongodb.net/<dbname>?retryWrites=true&w=majority
EMAIL_ALIAS=Your Name<[email protected]>
[email protected]
EMAIL_PASS=your-transactional-email-provider-account-password
[email protected]
EMAIL_USER=your-transactional-email-provider-account-username
P24_CRC=przelewy24-crc-code
P24_ID=przelewy24-merchant-id
P24_TEST=true
