 1 | # basicWebRTC
 2 | 
 3 | Setup your own Videoconference Server for 1on1 and group calls! All Calls are encrypted Peer 2 Peer!
 4 | 
 5 | ## Functions
 6 | * Audio
 7 | * Video
 8 | * 1on1 and group Calls
 9 | * Screenshare
10 | 
11 | ## Install ##
12 | 
13 | 1. Install node and clone this repo
14 | 2. run: npm i
15 | 3. run: node server.js
16 | 4. surf to: http://IP:3001
17 | 
18 | ### All User parameters ###
19 | * `username` -> Change your username shown
20 | * `roomname` -> Change the name of the room
21 | * `camon` -> Default is on. Set to false to start session audio only
22 | * `socketdomain` -> Change if you want to use a different socketServer (Can also include path: `https://domainname.tld/path/sub/`)
23 | * `base64domain` -> true if socketDomain is given in base64 format
24 | 
25 | Example: change the roomname: https://IP:3001/#roomname=yourSecretRoom
26 | 
27 | ### Config Server Listen IP & Port
28 | 
29 | Change the env variables: listen_ip ("0.0.0.0" default) and listen_port (3001 default)
30 | 
31 | ### Behind a nginx reverse Proxy
32 | ```
33 | location /basicwebrtc/ {
34 | 	resolver 127.0.0.1 valid=30s;
35 | 	proxy_set_header HOST $host;
36 | 	proxy_http_version 1.1;
37 | 	proxy_set_header Upgrade $http_upgrade;
38 | 	proxy_set_header Connection upgrade;
39 | 	proxy_pass http://127.0.0.1:8080/;
40 | }
41 | ```
42 | ## STUN and TURN Configuration ##
43 | If your clients are behind firewalls you might need to setup a TURN Server so the connection can fallback to that (Connection is e2e encrypted in any case).
44 | 
45 | If you have your STUN/TURN Server, isert the urls into:
46 | /iceservers.json
47 | 
48 | ### Setup your own TURN Server with docker ###
49 | This setup is using COTURN inside docker.
50 | The server is listening on Ports 443 and 4433 because on many firewalls only webtraffic is allowed. So you need to set this up on a second server.
51 | 
52 | If your server ip is 10.10.10.10 and your want to name it "myturnserver" run it like this:
53 | 
54 | Run `docker run -d --net=host --restart=always rofl256/turnserver usernameAdmin passwordAdmin realm "10.10.10.10" "10.10.10.10" "10.10.10.10" authSecret`
55 | 
56 | Don't forget to change the admin username, password and authSecret. 
57 | 
58 | For more configurations of this  take a look at repo of the container (https://github.com/cracker0dks/turn-server-docker-image) and the COTURN repo itself: https://github.com/coturn/coturn
59 | 
60 | If you have the turn server running, make a new entry into /iceservers.json
61 | ```
62 | [
63 |     {
64 |         "url": "stun:10.10.10.10:443"
65 |     },
66 |     {
67 |         "url": "turn:10.10.10.10:443",
68 |         "turnServerCredential": "authSecret",
69 |         "username": "webrtcuser"
70 |     }
71 | ]
72 | ```
73 | Change the ips and authSecret as defined on docker run. The username can be set to anything you want or leave it like this then restart the basicwebrtc server.
