Bootstraped with:

$ npx create-react-app my-app --template typescript
$ cd my-app/
$ npx sb init --use-npm
$ npm add -D loki

Added src/stories/DelayedComponent.jsx and src/stories/DelayedComponent.stories.jsx.

Run $ npm run storybook and then $ npm run loki test. The examples look fine in Storybook itself, but Loki reports Fetching stories Failed fetching stories because the server is down.
