next-codegrid - query country code

Modification of the codegrid-js library for use in Next.js.

bundles all tiles as javascript chunks – both for client and server
this process adds 10 secs to the next build (TODO: optimize - store in /public ?)
- output size is 10.5 MB (see .next/static/chunks)
first resolve takes ~40ms (both client and server), subsequent resolves are instant if it falls to the same tile
- fetches 35kb for worldgrid, then 100-300kb for tile (or 13kb gzipped, then ~50kB for tile)
sadly the generator is lost, so no more updates to the tiles: http://github.com/hlaw/codegrid

Usage

yarn add next-codegrid

import { resolveCountryCode } from 'react-codegrid';

const code = await resolveCountryCode([lon, lat]);

Country Code Data in the tiles directory produced from Openstreetmap (http://www.openstreetmap.org). Data under Openstreetmap are available under ODbL.
