On the client side, we are going to let the users record a live video and post it as a response. For this, we are going to use WebRTC (https://webrtc.org/) and an awesome helper library named RecordRTC (https://github.com/muaz-khan/RecordRTC) by Muaz Khan (https://github.com/muaz-khan). In the Command Prompt or Terminal pointing at the application root folder, run the following command to install recordrtc as a dependency:

$ npm install --save recordrtc

Or, run this:

$ yarn add recordrtc

Since this is not an Angular component, we are not going to bootstrap it. We are going to utilize it as a global variable.
