Re:
Places.js

Some basic features:

• Faster than you need; a round-trip query averages 20-30ms
• Lazy-load a global cities database in under 400kB over the wire
• Filter by country to optimise file size: France weighs in at 20kB and Australia comes in under 5kB
• Filter results based on a user's IP, proximity to a lat,lng, or the area inside a polygon or bounding box
• Standalone, or as a zero-config proxy to extend the life of Algolia's Places.js (beyond their API shutdown)
• Entirely static, nothing required beyond your favourite CDN or storage bucket
• Entirely free and open source (code is MIT licensed, database is CC BY 4.0)
• Contributions celebrated!

re:places depends on @lucaong/MiniSearch and @rowanwins/point-in-polygon-hao (both MIT / 0 dependencies). The database is derived from the basic World Cities Database available from SimpleMaps.com (CC BY 4.0). Ideas mixed in from @turfjs and this stackoverflow answer. Cloudflare's 1.1.1.1 supplies location hints. Informing everything, of course, is the masterwork that is Algolia Places.
All amazing efforts. Thank you so much.
