Add #92 - Generate exact single tile

[montzkie18]

Exposing new method geoJSONToTile to generate a specific VT based on passed z/x/y values.

This should skip generating parent tiles on all higher zoom levels for the requested tile.

This ports the C++ functionality implemented by @asheemmamoowala in mapbox/geojson-vt-cpp#65

Please merge this.

hi @mourner - any chance I can get a review on this one? thanks!

[mourner]

Sorry for the late response. I'll need to consider this change more thoroughly because this is technically breaking for the UMD bundle — when you have both default and named exports, the bundle will expose geojsonvt as geojsonvt.default.

@mourner would you be open to a version of this that just tacks something like singleTileFromGeoJSON() on to the exported geojsonvt function?

i.e. geojsonvt.singleTileFromGeoJSON = function() { /* do things */ }

That's maybe a little weird, but it sidesteps the export issue at least

@mourner @montzkie18 Any update on this?
It will be nice if this can be merged soon!

@mourner Hey! It's been a hot sec. I started looking for this use case and came across this PR. Is this something that you'd still be interested in merging in? Otherwise I can host a fork with the changes.

I would also really like this for my project. My goal is to take a WFS GetFeature response for a given bbox that correlates to a z/x/y tile ID, convert the features to GeoJSON, and finally convert the features to a vector tile. In the meantime, I may have to make use of patch-package.

@neodescis The State of Colorado is currently hosting this version: https://github.com/dfpc-coe/geojson-vt. My hope is that MapLibre will eventually host these changes

Do you have it published to the npm public repo? If so, I'm not finding it.

We have on boarded a fork of this project to maplibre org now.
If you would like to open a PR there I'll be happy to review it.

@HarelM that sounds a bit misleading. You have forked the project and will maintain a Maplibre-focused fork, but geojson-vt still remains and will be maintained here.

You are right, sorry, I have updated the message above.
