Development

The dev env for this is Node LTS/latest with ESM (import/export) syntax as a standard. Typescript is used to ensure type safety + documentation Linting is done with eslint and testing with jest.

You can run tests locally with npm t. Every PR also builds on Travis CI under these circumstances.
