Sharing your experience with JSON:API

Hi,

I’m curious whats your experience with Elm and JSON:API. I would be interested what works well, what is hard and if there are some things that are by Elm’s nature impossible to achieve.

Thank you

I’ve been using https://package.elm-lang.org/packages/FabienHenon/jsonapi/latest/ for this, which seems to work pretty well so far. My use-case is pretty simple, but I am using relationships and metadata, both of which are easy to setup with that library.

Here’s an example of how I decode relationships (aka. includes):

import Json.Decode as Decode exposing (..)
import Json.Decode.Pipeline exposing (custom)
import JsonApi.Decode as Decode
import JsonApi.Resource exposing (Resource)

...
decoder resource =
  Decode.succeed
    (\... -> ...)
    |> custom (oneOf [ Decode.relationship "author" resource nameDecoder, succeed "Unknown" ])
    |> custom (maybe <| Decode.relationship "project" resource Projects.decoder)
    |> custom (oneOf [ Decode.relationships "tags" resource Categories.decoder, succeed [] ])
