Watch addon for changes

I want to contribute to an ember-cli addon, but I don't see an easy way to check my changes quickly. Now I have the source code of the addon locally, and the package.json of my ember-cli app looks similar to this:

...
"ember-addon": "file:../path/to/addon",
...

Right now I'm re-installing the addon after every change and re-launching my app. Is it possible to watch for changes on the addon and reload my app?
