Generate vector tile files in ProtoBuf (.pbf) in /build/vt/* using tippecanoe. Because we build map as static files, no geospatial server is needed.

mkdir -p dist/build/vt/
tippecanoe -e dist/build/vt/thaielection2562 --no-tile-compression thaielection2562.geojson
tippecanoe -e dist/build/vt/province --no-tile-compression province.geojson

Next we need to generate static site. Choose target hostname by setting environment variable HOSTNAME=. Edit map vector tile hostname (map_hostname) in generate-site.js, i.e. http://127.0.0.1:8080 if it's hosted on different website.

npm i handlebars

HOSTNAME=http://localhost:8080 node generate-site.js

Launch a local web server from this directory. For example if we run http-server.

npm i -g http-server
http-server dist/

Then browse to http://127.0.0.1:8080.
