Basically, as per https://github.com/MartinMalinda/ember-idle-scheduler

This is a non-exhaustive list of outstanding things to do before submitting a PR to HNPWA project:

Todo:

• Setup Fastboot deployment for initial content rendering before JS loads,
• Fix HTTP => HTTPS redirects,
• Fix colour contrast for accessibility tests,
• Reduce time to the first byte of index.html,
• Reduce CDN download time of vendor bundle,
• Better comment styling,
• Add /user/:id route,
• Make comment buttons bigger on mobile.

When installed as an app (in Android), the ability to share the current entry is lost (or not visible le enough for me, at least).

That would be a nice addition to this already very good app!

It'd be nice to load user profiles when hovering over their name, similar to Twitter, and being able to click through to the actual profile.

There might be some performance gains from unbinding the render of the each list item, as we don't update the page once rendered.

More to reduce vendor bundle size: We can remove jQuery and use native events. We're only targeting evergreen browsers anyway.

• Replace Ajax with https://github.com/stefanpenner/ember-fetch
• Use native event dispatcher https://github.com/rwjblue/ember-native-dom-event-dispatcher/
• Remove jQuery from build

Expected improvement: ~12%

Thanks for hackernews.io and well done!

This isn't a standard Hacker News feature but some clients have collapsible comments to make reading comments on mobile easier. Would you be open to a PR adding this feature?

The polyfill adds a lot of code just for developer happiness and not much to the functionality of this app, so we should remove it, and be slightly less happy. I don't think we need it, and if we're using it anywhere we should be able to replace that code with Promises.

To help reduce the bundle size, It'd be good to remove moment because we only use one helper out of that package. Perhaps we could use https://github.com/oskarrough/ember-date-fns or cherry pick something out of there.

How fix this error?
