Taaabs is a single page application using Polymer and running in a browser. Taaabs is written in HTML and JavaScript. Taaabs use gulp as Task-Runner/build tool, npm and bower for dependency management. Theses tools needs Node.js runtime environment.

node and npm should be installed with your distribution package manager (apt-get, yum, pacman…) if possible and if the version packaged for your distribution is the actual stable Node.js version. At least you need a node version >= 0.12.7 and npm version >= 2.14.1.

You can check theses version with node –version and npm –version.

If your distribution package manager cannot, no problem, you can download and install node (since v0.12, npm is packaged inside node, so you don't need to install it separatly) Download Node.js.

Assuming now you have node, npm properly installed.

We use npm for installing build tools and build dependencies.

Then, you need to install gulp, as an executable application. [sudo] npm install -g gulp will install gulp for you in /usr/lib/node_modules/ and the executable will be available as a link on /usr/bin.

Now you can try the command gulp in your terminal. If you see in the standard output something like “local gulp not found”, you have succefully installed gulp.
