Linking to a Live Project
You can make changes locally to Sapper and test it against a local Sapper project. For a quick project that takes almost no setup, use the default sapper-template project. Instruction on setup are found in that project repository.
To link Sapper to your project, from the root of your local Sapper git checkout:
cd sapper
npm link
Then, to link from sapper-template (or any other given project):
cd sapper-template
npm link sapper
You should be good to test changes locally.
Running Tests
