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

npm run test
