node-firefox-reload-css Build Status

Reload CSS stylesheets on a running app on a Firefox runtime.

This is part of the node-firefox project.

NOTE: This module is super experimental and the API is not totally stable yet. Use under your own responsibility.


From git

git clone
cd node-firefox-reload-css
npm install

If you want to update later on:

cd node-firefox-reload-css
git pull origin master
npm install


npm install node-firefox-reload-css


reloadCSS(options) // returns a Promise

where options is a plain Object which must contain the following:

  • app: an object containing the description of an installed app in the client (you must have obtained this after a call to node-firefox-find-app.
  • client: the remote client where we want to reload the style sheets
  • srcPath: the source for the app

If no options are provided, or if options is an empty Object ({}), or missing then uninstallApp will fail (how can you uninstall you don't know what app exactly from you don't know where?)

Reloading the app stylesheets on change (using the npm watch module)

var watch = require('watch');
var reloadCSS = require('node-firefox-reload-css');
var appPath = '/path/to/your/app/code';
var appCSSPath = path.join(appPath, 'css');
watch.createMonitor(appCSSPath, function(monitor) {
  monitor.on('changed', function(f, curr, prev) {
      client: client,
      app: app,
      srcPath: appPath

You can have a look at the examples folder for a complete example.

Running the tests

After installing, you can simply run the following from the module folder:

npm test

To add a new unit test file, create a new file in the tests/unit folder. Any file that matches test.*.js will be run as a test by the appropriate test runner, based on the folder location.

We use gulp behind the scenes to run the test; if you don't have it installed globally you can use npm gulp from inside the project's root folder to run gulp.

Code quality and style

Because we have multiple contributors working on our projects, we value consistent code styles. It makes it easier to read code written by many people! :-)

Our tests include unit tests as well as code quality ("linting") tests that make sure our test pass a style guide and JSHint. Instead of submitting code with the wrong indentation or a different style, run the tests and you will be told where your code quality/style differs from ours and instructions on how to fix it.
