Transform your javascript with Browserify

Tired of battling endless <script> tags in your html files? Fed up with messing with a dozen libraries cluttering up the place? Can't see the wood from the trees? Try browserify (+ rollupify + wzrd)! It's amazing! It's awesome! It tidies up your code for you, so you don't have to (perhaps not :P)!

Seriously though, I've just been playing around with browserify, and it's awesome. It's that missing thing I've been trying to find for a long time. But what does it actually do, you ask?

Well, perhaps it's best to use an example. Consider these (relatively) harmless javascript files:

// SillySay.js
"use strict";

function sillySay(sentence) {
    // Split the sentence up into words
    var words = splitWords(sentence);

    // Loop over all the words in the above array and display them one by one
    for(let i in words) {
// WordSplitter.js
"use strict";
function splitWords(sentence) {
    // Split the sentence on whitespace and return the resulting array
    return sentence.split(/\s+/g);

To use our (perfectly ridiculous) example code, we not only have to include SillySay.js, but WordSplitter.js (this could be a library you use for example) as well:

<!DOCTYPE html>
        <meta charset='utf-8' />
        <title>Silly Say Demo</title>
        <p>Silly Say Demo</p>
        <p>By <a href="">Starbeamrainbowlabs</a></p>

        <script src="WordSplitter.js"></script>
        <script src="SillySay.js" charset="utf-8"></script>
            window.addEventListener("load", function(event) {
                sillySay("This is a test");

            html, body { font-size: 100%; }
                font-family: sans-serif;

That's looking a bit messy, but imagine what it'd be like if you added another few libraries? Or a new feature in a separate file? See the problem? Browserify solves just this issue. It analyses the dependencies of the entry point to your app, and bundles up all your code into a single file, nice and neat. You can add extra transforms (like plugins), too, to do extra things like automatically insert your app's version, or include other data files automatically, or transpile other languages to javascript automagically (full list here).

Sounds cool yet? Let me give you a quick tutorial on how I set up Browserify, with Rollupify and Wzrd.

Firstly, we need to set things up. If you don't have Node.js installed, do that now. You'll also get npm - Node's (perfectly awesome!) package manager. Next, let's create a quick project and paste in the code above. I've recorded an asciicast (as you may have seen a few times before here) of me going through the process:

(Can't see the asciicast above? Try viewing it here

If you'd like to take a look at the final result, as written in the asciicast above, you can find it over here. Questions and comments are welcome below :-)

My favourite Atom packages

The atom banner.

A while ago I posted about how much I like the Atom editor. A few months on, and I'm still in agreement: The Atom editor is an absolutely lovely general purpose editor. It's got a bewildering array of plugins, and I thought that I'd share a few of my favourites with you.

Termrk has to be my number one. It adds a toggleable terminal to the bottom of the screen (and presumably other sides too!). This is particularly useful for sorting out particularly nasty version control system problems, or using a quick one liner to process a few files, or starting a development server in the background. If you know your way around the console / terminal, this package is a must have.

Git Plus is also really useful. As you might suspect, it brings git integration to atom. It has a gui for all the common git commands - committing, branching, pushing, pulling, and more. If you use git, install this package.

Minimap and friends are awesome. If you didn't know about the map mode for the scroll bar in Visual Studio (go to tools and search for "map"), this package brings that to Atom. It has a bunch of plugins, too - which let you preview other points on the minimap, or show the current selection, or show changes since the last git commit. Its appearance is simple and uncomplicated, with one 'pixel' for each character - coloured according to that character's colour. I've been finding it to be just what I need when you're dealing with a large complex codebase. (and minimap-titles is an awesome extra too)

If you use multiple computers, sync-settings is worth a look. It synchronises your settings and installed packages by using a Github gist. I use it as a backup for my settings, but it'll be also useful when I finally get around to setting up a portable installation of atom on my flash drive.

There are a ton of other brilliant packages out there that I've found and I could write about them all night, but that would make this post way too long :) If you're interested in which packages I've got installed, I've uploaded a list to pastebin.

The Atom Editor is Awesome

The Atom editor.

Recently a friend of mine (who you can find on GitHub here) reintroduced me to the atom editor, which is built by GitHub. I looked at it a while back, but it was too unstable and lacked too many features for me to consider using it as my main editor. Fast forward a few years, and it's much more stable. It even comes with batteries included - it has an awesome files panel (in which you can open multiple folders), a GUI for the settings (which brackets doesn't have), and a package ecosystem which can be utilised without leaving atom. It shows you the readme for packages too, so you always know how to use packages that you've got installed (or are considering installing).

If you've heard of atom before, give it another go! You might be surprised. If you haven't, you don't know what you're missing out on.

IP version tester

You may have heard already - we have run out of IPv4 addresses. An IPv4 address is 32 bits long and looks like this: If you count up all the possible combinations (considering each section may be between 0 and 255), missing out the addresses reserved for special purposes, you get about 3,706,452,992 addresses.

The new system that the world is currently moving to (very slowly mind you) is called IPv6 and is 128 bits long. They look like this: 2001:41d0:52:a00::68e. This gives us a virtually unlimited supply of addresses so we should never run out.

The problem is that the world is moving far too slowly over to it and you can never be sure if you have IPv6 connectivity or not. I built a quick IP version tester to solve this problem. I know there are others out there, but I wanted to build one myself :)

You can find it here: Ip Version Tester.



Today I have for you a traceroute tool that I have built. I made it mainly for educational purposes, since I wanted to test the code behind it ready for something slightly more complicated.

Here is an example:

Traceroute Plus
By Starbeamrainbowlabs <>

=== ===
 1: 1ms
 2: 33ms
 3: 36ms
 4: 54ms
 5:     119ms
 6:    115ms
 7:  118ms
 8:   118ms
=== end ===

You can download the latest version of the tool here: TraceRoutePlus.exe

The code is up on github, and pull requests are welcome :)

An Animated GIF Renderer

The online tool I am releasing today is another one of the projects I did a while ago (December 2013 in this case). The difference here is that someone asked me to build it for them. The tool allows you to stich a number of still images into an animated gif.

Having an online version of the tool on a server that I own seems like a good idea (so I can keep it up to date) - so I am releasing it on this site for you to use.

It uses a javascript library called gif.js to render the still images as an animated gif. Please bear in mind that all the rendering is done on your computer! Nothing is uploaded to the server at all. If you refresh the page, everything will be reset.

A description of the options and known issues can be found below. If you just want to skip all that and play around with it for yourself, please follow this link:

Animated GIF Renderer


A description of all the options available can be found below:

Option Description
Repeats The number of repeats. -1 = no repeat, 0 = repeat forever.
Default Delay The default delay each still image should be given when first dragged into the tool. Remember to set this before you drag all your images in to save time!
Frames per second An alternative method of setting the default delay. Simply enter the number of frame you want to show per second.
Workers* The number of threads to use to render the animated gif. For optimum performace enter the number of cpu cores you have. This will speed up the rendering process for large gifs.
Quality* The quality of the resultant gif. In the code this is referred to as the pixel sample interval. I don't really understand this setting myself - if you do, please leave a comment below and I will update both this post and the tool itself.

A '*' indicates an advanced setting.

Known issues

  • The 'x' button to remove an image is buggy. - Fixed! A new image removal system has been implemented to fix this bug.
  • The size of the rendered gif i snot updated when images are removed - Fixed! The maximum image dimensions are now recalculated when an image is removed.
  • Found another bug? Report it below.
