Backend for booking Yoga Classes built on Ktor-Server

• Built HTTP POST end points for the login, signup and register features with corresponding models for the Response request and Body.
• Implemented the HTTP GET end point for authentication, which contains the JWT Auth token in header and unique user id in the query param.
• Used Kotlin Coroutines for multithreading
• Used salting and hashing techniques and algorithms like SHA256 & HMAC signature, to protect the user data and privacy.
• Used a clean architecture and basic design patterns for scalability.

• Backend: Kotlin Ktor-Server
• Database: KMongo Atlas
• Container: Docker
• IDE: IntelliJ Idea
• API Testing: Postman

• The app contains a Dockerfile which can be used to containerize the application and is thus Cloud Native.

• The app is currently deployed on renderer & the database is hosted on AWS.

• Note: Since the app is hosted using a free plan of render, the server stops after being idle for some time.
• Desi Jugaad: Make sure to hit the base end point a couple of times before using the app until you see this message - "Welcome to the Yoga App!" to wake the server up from sleep and make it up and running!
