A basic start to a pixi game.

pixi-skel.js

function Game(somediv) {
  this.stage = new PIXI.Stage(0xFFFFFF);
  this.renderer = PIXI.autoDetectRenderer(800, 600);
  somediv.appendChild(this.renderer.view);
  this.lastframe = Date.now();
  this.rocket = new Rocket(this);
  this.update();
}

Game.protototype.update = function () {
  requestAnimationFrame(this.update.bind(this));
  var now = Date.now();
  var frameMS = now - this.lastframe;
  this.lastframe = now;
  this.rocket.update(frameMS);
  //loop through and update any other objects to deal with their
  //individual logic and update their sprites positions
  this.renderer.render(this.stage);
}

function Rocket(game) {
  this.game = game;
  this.sprite = PIXI.Sprite.fromImage("rocket.png");
  this.game.stage.addChild(this.sprite);
}

Rocket.prototype.update = function (frameMS) {
  //Some update to this.sprite.position scaled with frameMS
}
