I am new to leaflet. currently I am working on leaflet to render vector tiles. my application's requirement is that on click i should get features from map tiles in geojson format.
In Mapbox map.queryRenderedFeatures(e.point). I want to do exact same thing, but in leaflet. Please check here to check how mapbox is fetching features.
Please help.
Current Leaflet implementation does not supports querying rendered features. Hence switching to Mapboxgl

In mapbox studio I have a lot of layers for customizations. Is there a way to access those layers programmatically with js. For example hide all WATER or ROAD layer on the map with js?
Thanks.
You can try using https://github.com/mapbox/vt2geojson to get geojson data for whichever layers you are interested in and then use this data and add styling using mapbox gl js maps.
Hope that answers your question.
I want to create georeferenced map tiles from raster (jpg map of small area) and display in Leaflet. MapTiler seems to be a prefect solution for my problem, but free version doesn't allow set zoom range, aslo has a watermark.
Is there any free/opensource solution with same funcionality? Im woking on non-profit project, so dont have any budget.
See https://stackoverflow.com/a/13641838/4768502 for a pointer to gdal2tiles.
You can also use other software such as GeoServer, MapServer or MapProxy to serve tiles based on an image or some vector data.
I am still learning more about leaflet 1. I went through the change log saw a lot of improvement was done for vector.
Does leaflet 1 have it's own way for vector tiles without using Mapbox GL?
Leaflet can't do that out-of-the-box but you could use the vectortile plugin:
A Leaflet Plugin that renders Mapbox Vector Tiles on HTML5 Canvas. Though there is extensive use of MapboxVectorTiles in Mapnik PNG tile rendering as well as MapboxGL, there is a strange lacking of libraries that integrate these vector tiles directly into Leaflet. Search no more, the library you have been looking for is here!

I have a complete set of waypoints (beginning, end, every intersection) and I'd like to display this on a map. I don't want to use a routing service and it should be offline.
How can I draw polylines on a map so that they follow the curves of the road?
I'm using leaflet.
Could the data be extracted from a relational database(PostgreSQL) and then convert it into GeoJSON and display on the map by leaflet?
I can't use any paid services either.
Leaflet has a polyline object. MapBox has a nice example how to use it.
I think scai has given you a good example to practice.By the way you can also store the data in JSON format in PostgreSQL.Refer this documentation for more details.JSON Types
In brief, I’m looking for a way to either flatten layers in MapBox, or import a MapBox project into TileMill so I can flatten it into a new tile set.
My problem is this: I’m working with StroyMapJS (a JavaScript library) and it only recognizes the base layer coming from MapBox, with no additional layers. However, I have some vector data that is a critical part of the story that I want included. My thinking is that if I can flatten or merge the layers into a new basemap I would be fine. So, I would either:
Do this directly in MapBox – but I can’t find a feature to do this, or
Import the Terrain MapBox layer into TileMill, add my vector
data, and then export as a new set of tiles and create a new project
from these tiles in MapBox - but I can’t figure out how to bring a
MapBox project into TileMill.
Am I going about this the wrong way or am I mission something?
Thanks
but I can’t figure out how to bring a MapBox project into TileMill.
You would export your markers & overlays as GeoJSON - this will be in the Project UI in the map editor. Then you can import that GeoJSON into TileMill as a datasource.
