JavaScript Application Design

A Build First Approach

Accompanying code samples and snippets for the JavaScript Application Design: A Build First Approach book.

These are the accompanying code samples and snippets for a book I wrote about JavaScript build processes and application architecture. The samples are organized by chapter, and they appear in the same order as they do in the book, for convenience.

Fell out of the skies and would like to learn more about the book?

Book buying frenzy? Say no more, stranger!

Installation Pre-Requisites

You'll need Node.js. You can get the latest version from their website, although I'd suggest using nvm, which makes it super easy to install multiple versions, and switch between them.

You'll need GraphicsMagick, and also phantomjs, to run some of the examples. PhantomJS comes in a module that you can conveniently install as a global.

npm install -g phantomjs

GraphicsMagick comes in different distributions for OSX, Linux, and Windows, so please refer to their site to download the appropriate distribution. If you're on Ubuntu, I'd recommend installing it through apt-get. If you're on OSX, you can use brew to install it. These kinds of tooling download automation present the most benefits when you automate all of your development environment provisioning, enhancing consistency across fresh installs in your systems. As an example, you can take a look at my dotfiles project, for reference.

Installation

Once you have Node and the other tools you'll need, use the command below to clone this repository and install all of the dependencies:

curl https://raw.githubusercontent.com/buildfirst/buildfirst/master/install.sh | sh

_{If you're on Windows use install-dos.sh, instead.}

That's it! You are now free to roam the sample directories and follow the instructions in each of them!

Manual installation instructions can be found here, but you shouldn't need any of that.

Execution

To run an example, read its README.md and follow the instructions I've placed there. I tried to make them as straightforward as possible, but sometimes they might not match the examples in the book to the letter.

There are some examples here that you won't find on the book, those will generally be a bit longer: exactly the reason why I didn't include them in the book. Although the code itself might not be present in the book, most of the explaining will definitely be there, rather than here.
