DougTV is a One-To-Many Video Broadcast Full-Stack Web App that allows users to quickly launch a live broadcast video stream and be publicly seen and heard by an audience anywhere in the world!

Built with React.js with Hooks, Node.js with Express, and PostgreSQL. The video broadcast feature is facilitated by socket.io and a WebRTC RTCPeerConnection.

• Video Walkthrough Of DougTV

• Edge Case Fix For DougTV

Users are able to:

• Search for active streams and quickly know if there are no active streams currently available
• Launch a new Broadcast by
  • Entering a publicly visible display name
  • Clicking Connect to form stable connection
  • Clicking Start Broadcast to make the stream publicly visible on the home page
• End a Broadcast by
  • Clicking End Broadcast
• Watch a Broadcast by
  • Clicking a link to an active stream found on the Home Page
  • Clicking Connect on the Watch Page

A Manager is able to:

• Delete all disconnected Broadcasters who did not properly End Broadcast by
  • Clicking Clear Database on the top secret Wipeout page

A Cron Job has been set to:

• Automatically delete all disconnected Broadcasters who did not properly End Broadcast every 24 hours

• Delete Broadcaster on closed window/tab or unexpected user disconnect
• Live text chat between Broadcaster and Watchers facilitated by socket.io
• Quick share link to the Watch Page listed directly on the Broadcast Page for broadcasters to quickly share on social media when they go live
• Allowing Broadcasters to reconnect to a Broadcast they launch through localstorage
• Secure and encrypted user accounts

• This Full Stack Web App was created as both a tech demo and steppingstone in learning and utilizing WebRTC to launch a one-to-many Video Broadcast
• Lessons learned in creating DougTV were used in the creation of my award winning Pursuit 2020 Capstone Project, Pantry Party
• Understanding what the RTCPeerConnection is and how it can be properly shared behind NAT Servers
• Learning how to collect the ICE credentials from two or more potential connecting peers
• Disabling audio on the Broadcast's video display so a broadcaster isn't bothered by a echo while presenting
• Having an accurate active viewer count displayed on the Broadcast page
• Disabling the Start Broadcast button once a connection has been made and a stream is publicly displayed on the Home Page

• Node.js & Express.js For the HTTP backend server
• React.js For the front-end/client interface of my app
• PostgreSQL As my relation database management system
• pg-promise For interfacing with my database in my backend code
• socket.io For allowing real time real time interactions between two or more peers
• WebRTC The RTCPeerConnection is the data stream shared between peers
• STUN Server A Google provided simple server that shares the ICE credentials (the public facing IP address) to bypass the NAT Server and permit the RTCPeerConnection

NOTE: This repo has been configured for deployment on Heroku, but can be run locally after a few adjustments.

You must install Node.js as well as PostgreSQL in your computer.

You can check for these dependencies with node -v and psql -v. If your shell/terminal doesn't complain and you see version numbers you are good to go.

1. Clone this repo into a folder of your choice:

       git clone https://github.com/DouglasMacKrell/DougTV.git

2. Install dependencies for the Node/Express Server:

       npm install

3. Install dependencies for the React App (client folder):

       cd client && npm install

4. Create database and seed sample data. While inside the root directory, open the seed.sql file and:

   • Change

        DROP TABLE IF exists broadcasters;
   

   • to

        DROP DATABASE IF EXISTS dougtv;  
        CREATE DATABASE dougtv;  
        \c dougtv;
   

   • Then seed the new database from the root folder:

      cd ..  
      psql -f seed.sql
   

Make sure PostgreSQL is running!

5. To launch the Node/Express server, inside the root folder run:

       npm start

6. Before you can launch the React App, you must target the ENDPOINT of the socket.io server within the three files that use this connection. In the client => src => components folder, open the Broadcast.jsx file within the Broadcast folder.

   • On line 28, change

        const ENDPOINT = "https://dougtv.herokuapp.com/";
   

   • to

        const ENDPOINT = "http://127.0.0.1:4004";
   

7. Next, from the components folder, open Join.jsx within the Join folder.

   • On line 13, change

        const ENDPOINT = "https://dougtv.herokuapp.com/";
   

   • to

        const ENDPOINT = "http://127.0.0.1:4004";
   

8. Finally, from the components folder, open Watch.jsx within the Watch folder.

   • On line 18, change

        const ENDPOINT = "https://dougtv.herokuapp.com/";
   

   • to

        const ENDPOINT = "http://127.0.0.1:4004";
   

9. To launch the React App, inside the client folder, and preferably in another terminal window run:

       npm start

10. A new browser tab should have been opened and the App should be running. If that is not the case check the terminals output for errors, if you are unable to troubleshoot the problem, I would be happy to address issues so open one
