Re: [Interest] MapboxGL offline and custom vector tiles source
The current map items implementation is a bit buggy and somewhat slow. There's one new patch line, hopefully landing in 5.15, that should improve performance and also the visual appearence On Mon, 23 Dec 2019 09:46:22 +0100 maitai wrote: > Yes it includes texts, images (icons), and many kinds of shapes > (polygons filled with patterns, etc). > > I am trying to play with geojson for a week or so to see if it fits my > needs, but I am facing some issues with polygons, maybe this is on my > side so I need to investigate more. > > Is there a clean way to prevent the plugin to try to download tiles from > mapbox or elsewhere and just use custom layers, paints, layouts > MapParameters?

Thanks, I will have a close look.

Re: [Interest] MapboxGL offline and custom vector tiles source
Yes it includes texts, images (icons), and many kinds of shapes (polygons filled with patterns, etc). I am trying to play with geojson for a week or so to see if it fits my needs, but I am facing some issues with polygons, maybe this is on my side so I need to investigate more. Is there a clean way to prevent the plugin to try to download tiles from mapbox or elsewhere and just use custom layers, paints, layouts MapParameters? For the time being I am putting a dummy mapboxgl.mapping.additional_style_urls parameter (http://none) but this is not very clean... Philippe.

[Interest] MapboxGL offline and custom vector tiles source
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?
