slippy

this is a tiny service you can use as a synchronous api service

it makes this shard accessible via a REST API https://github.com/simonneutert/slippy_tiles

if you need to have asyncronous operations, I suggest to simply add a gateway microservice in front of this one managing webhooks.

at best you modify this project to work with webhooks or without and push your changes.

By default this service runs on http://0.0.0.0:3000

Installation

Have Crystal Lang in version 1.0 installed and fully working (OpenSSL and such).
