I recently have been working a lot using Leaflet.js to do some mapping.
In some of my models, I use the lovely
Geo package for Elixir point and geospatial usage. I needed to add support for Poison to encode my model.
I’ve been serving geo json from my models, and I needed a way to use the JSON encoding way easier. I’m sending some data out to a ZeroMQ socket so I need to encode it by transorming my Geo module in a way that I could encode it with Geo JSON.
I modified my model in two ways – one by putting the
@derive directive to tell Poison to encode only certain fields. That is one way.
In another way, I needed to encode it everytime by calling the
Geo.JSON.encode method without me having to do it. You can see that in the
