UI: Migrate to Storybook (#6507) I originally planned to add component documentation, but as this dragged on and I found that JSDoc-to-Markdown sometimes needed hand-tuning, I decided to skip it and focus on replicating what was already present in Freestyle. Adding documentation is a finite task that can be revisited in the future. My goal was to migrate everything from Freestyle with as few changes as possible. Some adaptations that I found necessary: • the DelayedArray and DelayedTruth utilities that delay component rendering until slightly after initial render because without them: ◦ charts were rendering with zero width ◦ the JSON viewer was rendering with empty content • Storybook in Ember renders components in a routerless/controllerless context by default, so some component stories needed changes: ◦ table pagination/sorting stories access to query params, which necessitates some reaching into Ember internals to start routing and dynamically generate a Storybook route/controller to render components into ◦ some stories have a faux controller as part of their Storybook context that hosts setInterval-linked dynamic computed properties • some jiggery-pokery with anchor tags ◦ inert href='#' had to become href='javascript:; ◦ links that are actually meant to navigate need target='_parent' so they don’t navigate inside the Storybook iframe Maybe some of these could be addressed by fixes in ember-cli-storybook but I’m wary of digging around in there any more than I already have, as I’ve lost a lot of time to Storybook confusion and frustrations already 😞 The STORYBOOK=true environment variable tweaks some environment settings to get things working as expected in the Storybook context. I chose to: • use angle bracket invocation within stories rather than have to migrate them soon after having moved to Storybook • keep Freestyle around for now for its palette and typeface components
