[Interest] MapboxGL offline and custom vector tiles source

[maitai]

Hello,

We would like to serve custom vector tiles, ideally though an API call 
or eventually a local server/stream. We don't want to add data or layers 
to an existing mapbox chart, but rather respond to tile queries by 
sending our own geojson tiles. We have already done that for OSM plugin 
(with raster tiles), but we don't really know where to start with 
concerning mapbox vector tiles.

The tiles are not stored in a database or mbtiles, but need to be 
generated on request.

What would be the best approach to achieve that?

Thanks for any tip
Philippe.
