how to create and run my own peerjs server?

问题:

I got the following code from the git-hub but I don't know how to use and execute.

 $> npm install peer   --->where i want to install this node_module ?
  //Run the server:

 $> peerjs --port 9000 --key peerjs     
         or
 var PeerServer = require('peer').PeerServer;
 var server = new PeerServer({port: 9000, path: '/myapp'});

what's the difference between above steps. when and where to use those steps.

回答1:

After npm install peer go to /root/node_modules/peer/node_modules/ws. Then add something like

var PeerServer = require('peer').PeerServer;
var server = PeerServer({port: 443, path: '/peerjs'});

in index.js and start the server with nodejs /root/node_modules/peer/node_modules/ws/index.js

回答2:

There are few ways to get peerjs-server:

1. npm install peer

2. git clone https://github.com/peers/peerjs-server

3. download and unpack zip-file from git

After that go to <path_to_peerjs-server>/bin and run peerjs-server with command:

node peerjs --port 9000 --key peerjs

or

./peerjs --port 9000 --key peerjs

peerjs-server has more options, and you can see them with command ./peerjs without arguments.
