console4Worker is console API for WebWorkers. WebWorkers are hard to debug. On top of that, console API is unavailable in WebWorkers. It doesn’t help.

console4Worker is a simple library which tries to fill this gap. It provides the console API , the same api you are used to. It implemented in most browser, node.js, even part of commonjs. See the demo in the examples/ directory.

On the Worker Side

First you include the script with this line.

1

importScripts('console4Worker-worker.js');

And you are done! Now you can console API as you would normally do, even if you are in a webworker. Lets say something like

1

console.log("console call made from inside a webworker");

Pacmaze just got an update. it was long overdue, i admit, other matters distracted me from it. It is good to be back on it tho. It is version 5 now. It is a major performance update, 5 time faster in some cases. The game is now embeddable in external pages. Additionnaly, Packy has been renamed Pucky as a reference to the original name of pacman, ‘Puck-Man’. You can read all about the history of pacman in the pacman dossier.

Embedded game

See an embedded version below. Use AWSD keys to play or play the full page version.

microcache.js is a micro library to handle in-memory cache. It is less than 20 lines and works in node and browser. It is available on github here under MIT license. If you hit bugs, fill issues on github. Feel free to fork, modify and have fun with it :)

Install it

To install it on node

GoWithTheFlow.js is a javascript asynchronous flow-control micro library which works in node.js and in browser. It allow to control how your asynchronous code is executed, sequentially or in parallel. Flow() is only 30lines.

How to use it

Let start with a basic example. 2 jobs run in sequence. The first job is a timeout so the result is delivered asynchronously, and a second job is run only after the completion of the first.

Flow().seq(function(next){
    console.log("step 1: started, it will last 1sec");
    setTimeout(function(){
        console.log("step 1: 1sec expired. Step 1 completed");
        next();
    }, 1000);
}).seq(function(next){
    console.log("step 2: run after step1 has been completed");
})

It will display the following

step 1: started, it will last 1sec
step 1: 1sec expired. Step 1 completed
step 2: run after step1 has been completed

This post describes a standalone way to add class inheritance in your javascript code. We will do that ala vapor.js, so no dependancy or external framework. A vaporjs inheritance is only 3 lines!

Lets get started, say you got a class animal. It gonna have a constructor and a method talk.

var Animal = function(opts){}
Animal.prototype.talk   = function(){ return 'mumble';  }
Animal.prototype.sleep  = function(){ return 'zzzzz';   }

parisjs #7 was fun as always. I did a flash talk on shorttag.js and presented what i did on pacmaze experiment this month. Here are the slides i used.

Btw ryah is coming to paris on june 8th, register.

Yesterday, the first london webgl meeting happened! people interested in webgl all in a same place and time, it was nice. see reports here and here.

I talked about pacmaze experiment, here are the slides i used.

A nice picture from @tbx. I love the packy checking on me while im presenting him to audience :) reccursive gamification ftw!

Paul Irish recently wrote requestAnimationFrame for smart animating. It is a polyfill so people can start use requestAnimationFrame() today and still be future proof.

This post is about its counterpart, cancelRequestAnimFrame(). It cancels a requestAnimationFrame(), like clearTimeout cancels a setTimeout.

Yesterday i was at parisjs talking about html5 and game. I presented games from the Pacmaze Experiment and talked about html5 technology in it. Here are the slides i used.

Buddymaze is a clone of midimaze, an old game where people shoot at each other. You can find it as standalone webapp or in chrome web store. This is the second game in the pacmaze experiment announced here, the first one being pacmaze. This version is rather rought, i will keep you updated. Considere it as a early beta.
