Overview of My Submission

WatchYaari is a platform where friends can watch youtube videos together while connected over a video chat. It is primarily built using MEAN stack, WebRTC, socket.io & Redis.

The idea for the same originated back in April 2020 when people were socially distant due to COVID-19 outbreak & while talking to bunch of friends over a video call, the need for hanging out with friends during social distancing was the bootstrap point of WatchYaari.
Initially we had started off with youtube but the plan was to extend integrating with various OTT platforms.

Submission Category:

MEAN/MERN Mavericks
I have used Redis in the following 2 ways:

1. As a primary database instead of MongoDB (i.e. replace “M” in MEAN/MERN with “R” for Redis).
2. Added caching and advanced searching capabilities using JSON and Search modules.
