If you’ve ever wanted to export maps from QGIS to the Web then you need to check out qgis2web by Tom Chadwin. This plugin has historically supported exporting your maps as Leaflet or OpenLayer maps, and has recently added support for exporting maps using Mapbox GL JS.
#qgis2web hits half a million downloads! To celebrate, Mapbox GL JS export and Leaflet attribute filters are now released in a new non-experimental version. Upgrade to 3.10.0, and report any problems at https://t.co/G9b6F7uvMb.
