Copy Once Past Anywhere

What it does

This is an app that helps users to copy text from mobile to desktop in a simple and easy manner. Whenever the user copies any text to clipboard in the mobile, it gets copied to the clipboard in the desktop or laptop. Similarly, if users copy any text to clipboard in the desktop, it gets automatically copied to the Mobile clipboard. Users should have both Android app (installed in their mobile) and Desktop app installed.

How I built it

We used Java for Android app development, electron.js for cross-platform Desktop app. The backend services are written in Node.js, using MongoDB as our database. The services and database are deployed on Google Cloud platform using Docker.

Challenges I ran into

We used websockets for sending clipboard data to mobile from desktop and vice versa. We faced challenges in ensuring proper working of this feature using websockets, which was very important from the performance point of view. Apart from this, we faced challenges in integrating different service and apps.
