How can PrePack help?

PrePack is a cloud based 'npm pack'

1. Open a PR
2. PrePack will build each commit and provide you a URL
3. This URL can be used in package.json
"@company/components": "URL"

This means you can properly test your changes,
run tests against the changes in another project, anything you'd like ✅
