What, How & Why?

This demo was created to demonstrate how Realm can be used as a cache for search results. It also shows various statistics in terms of disk usage and how much space the cache is using.

Nice! The app works for me now but I needed to adjust the search index's name capitalization, after that change should be all good.

Would be nice to also enforce some linting consistency like e.g.:

• " vs '
• {someName} vs { someName }
• Trailing commas
• End with ;

Perhaps we can extend some recommended configs.

It's probable that I never ran proper prettier/linting over this code.
Is the issue that the formatting differs from the other examples? Most probable it is because Expo comes with its own defaults.

I think generally just using the default of whatever platform is being used would be fine. Development teams will generally override this at some point anyway. If our example code hasn't applied the linting/prettier rules though, we should update that.

I think having some things differ from the other examples is fine from my point of view, it's mainly that it'd be good to keep it consistent within the project itself.

Awesome Andrew! 🥳 Thank you so much for adding this, definitely an interesting and helpful use case to have!
