Consider snapping modes

[davidgilbertson]

Hello there map friends. I've written some custom modes so the drawing tools snap to right angles and other features.

https://github.com/davidgilbertson/draw-geoson (and https://drawgeojson.firebaseapp.com/)

It's just the start of a larger project for me, but if you'd like to include the logic in this repo that'd be cool.

Pretty awesome, any chance you can update the repo link?

That repo grew into a commercial product and is no longer open source, sorry about that.

Hi @davidgilbertson, I found your example the only one currently working properly, I collected the code from your example in a Stackblitz project.
I hope It's ok since the code in your example was already public online. If not I will remove it.

for anyone looking for a snapping mode for mapbox-gl-draw, I've also created a snapping mode, which can snap to segments (in addition to vertices as in @davidgilbertson example). will publish that soon.

I created my version of snapping mode, it's in the early stages:

hope you enjoy it.
