I've got a working travis deploy here - https://github.com/kivlor/up-travis

Happy to create a PR here with it as an example :)

@kivlor Thanks for your sample Travis file, it helped a lot! As a NPM user, I also had to put up inside optionalDependencies in my package.json to prevent the npm install step from failing.

@louisremi that's odd 🤔
