Package Exports

cryptifier
cryptifier/src/app.ts

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cryptifier) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Testing

Tests are written in a BDD/Cucumber type syntax using mocha-cakes-2. Try to write tests in a meaningful way as to describe what it is you're testing and what resources are available. Testing does not only test a piece of code that it actually works but is also used for documentation purposes. Focus on testing what is vital for the feature.

To run all tests (including linting)...
