Yaocho — offline support for Mozilla products.

Yaocho is an offline enabled open webapp to view knowledge base articles from Mozilla Support.

You can download it from Firefox Marketplace at https://marketplace.firefox.com/app/mozilla-help .


git clone https://github.com/mozilla/yaocho.git
cd yaocho
npm install
gulp dev

Getting Started

To get you started you can simply clone the yaocho repository and install the dependencies:


For Debian systems you will need the package librsvg2-dev. For other systems you will need the equivilent package.

You need git to clone the yaocho repository. You can get it from http://git-scm.com/.

We also use a number of node.js tools to initialize and test yaocho. You must have node.js and its package manager (npm) installed. You can get them from http://nodejs.org/.

Clone yaocho

Clone the yaocho repository using [git][git]:

git clone https://github.com/mozilla/yaocho.git
cd yaocho

Install Dependencies

We have two kinds of dependencies in this project: tools and angular framework code. The tools help us manage and test the application.

  • We get the tools we depend upon via npm, the [node package manager][npm].
  • We get the angular code via bower, a [client-side code package manager][bower].

We have preconfigured npm to automatically run bower so we can simply do:

npm install

Behind the scenes this will also call bower install. You should find that you have two new folders in your project.

  • node_modules - contains the npm packages for the tools we need
  • app/bower_components - contains the angular framework files

Note that the bower_components folder would normally be installed in the root folder but yaocho changes this location through the .bowerrc file. Putting it in the app folder makes it easier to serve the files by a webserver.

Run the Application

Yaocho uses Gulp.js as a task runner. This should have been installed with the dependencies. Gulp has tasks to build various parts of the site, and tasks useful for deployment. The most important command for now is

gulp dev

You may have to run that as node_modules/.bin/gulp dev, if your path is not set up for node modules.

Now browse to the app at http://localhost:8000/.

Updating Angular

You can update the tool dependencies by running:

npm update

This will find the latest versions that match the version ranges specified in the package.json file.

You can update the Angular dependencies by running:

bower update

This will find the latest versions that match the version ranges specified in the bower.json file.
