JSGO

A javascript library for reading CS:GO demo files. It supports both the browser and node.js.

Once parsing starts most data is sent in the form of events. From there you can look up entity properties if needed for additional information.

Contact me on irc.esper.net #jsgo.

Installing in node

npm install jsgo

Example

var fs = require('fs');
var jsgo = require('jsgo');

fs.readFile('demo.dem', function(err, data) {

  new jsgo.Demo().on('game.weapon_fire', function(event) {
    
    var player = event.player;
    var position = player.getPos();

    console.log(player.getName() + ' used weapon ' +
            	event.weapon + ' at ' + position.x + ', ' + position.y + ', ' + position.z);
  
  }).parse(data);
  
});

Output:
