Low Latency Voice Call server with nodejs and webrtc

If you simply want to view the final product website, I'll have it running from time to time on: https://12d93698.nip.io/broadcaster/index.html

This tutorial will help you in your journey to try to run this project locally. If you want to run this project on an AWS server like I did, godspeed.

Setup

Clone the project, I would suggest Visual Studio Code.

VSCode:

1. Install the Github Pull Request extension if you haven't already
2. In a new window, under start, you should have an option to Clone Git Repository
3. Copy the HTTPS link under "< > Code"

• DO NOT COPY THE LINK IN THE BROWSER BAR

4. Paste it in the popup
5. Follow the directions VSCode gives you

Installing dependancies

1. Install NodeJS if you haven't already. I think it's also a VSCode extension.
2. In a terminal, try running node index.js inside the project folder

• If it fails outright, you either installed NodeJS improperly or aren't in the correct folder

3. When it gives you a big error, try to see what you need to install. It might be a few tries before you npm install everything.

Getting certificates

In order to run HTTPS, you need a couple .pem certificates. You can use whatever you want for this step, but I would suggest using openssl. The command that worked for me was: ./openssl genrsa -out localhost:8443 1024 -config openssl.cnf

Local files

npm install dotenv if you haven't already To run the project with security, I used .gitignore on a folder named local. This folder is in the main project folder and has a few files in it:

• .env
• cert.pem
• key.pem

.env contents:

PEMpassphrase=##########
PORT=8443
PRIVATE_KEY_PATH=./local/key.pem
CERTIFICATE_PATH=./local/cert.pem

Finally, you might be able to run this project locally using node index.js. If you have any issues, you can contact my consultant here
