What Is Ktor?

Ktor is a powerful Kotlin backend framework that is entirely based on coroutines. That makes it extremely performant because on the one hand it can handle many requests at once and on the other hand coroutines are more efficient than threads.

What Is MongoDB?

MongoDB is the most popular NoSQL database. Especially, with the library KMongo, its implementation is super simple with Kotlin. MongoDB synergizes extremely well with Ktor and will here be used to implement a full Register/Login system to save notes for each user.

What Will You Do in this Course?

You will implement your very own backend server with the powerful Ktor framework. After implementing the backend side, you will create a note app on Android to connect it to your server. Users will be able to register and login in your app to create notes and synchronize them on your server. All the notes will also be cached in a local database on the device for offline access. Users will be able to add owners to their notes, so that they can share their notes with other users who are then allowed to also read and edit these notes.

    This course is made really well and explained in a lot of detail. I would highly recommend this to anyone who wants to learn how to implement Ktor REST API in their apps. Hands down I wasn’t able to find any better course on this topic. And thanks to Philip I was able to pass my Associate Android Developer Exam.
