rescript-test VS elm-graphql

Besides bindings for JavaScript libraries, there is rescript-test - a lightweight test framework written in ReScript for ReScript. I have heard that some people like it, but for me, it lacks coverage output and Wallaby support.

As soon as you need to change the name or something, delete a field, or change a field… you’ve broken the API. This means you first need to change your Lambda(s) that use this new data, and ensure your unit tests (using ReTest) pass, and your integration tests (using Mocha & JavaScript) which invoke your Lambdas directly on a QA server still work.

To do that, we’re using rescript-test, which feels natural to those used to Jest, Mocha, etc. The only main difference is using testAsync vs test for async code, and having to define your own assertions vs. “Jest/Chai has ALL THE THINGS”.

Once I could quickly make calls against a server, and see the raw responses were matching up to my expectations, I moved to finding an Elm equivalent. Two years ago or so, Dillon had his GraphQL library and marketed it well.

The elm-graphql library enables code generation. This enables us to extend the “fearless refactoring” across the entire stack. As we build, learn, and eventually change our domain model from those learning’s, we can regenerate the front-end code needed, and the compiler lets us know what to modify (I still haven’t found something this powerful for ReScript yet).

I've managed to run the example from dillonkearns examples at master, however it is using a strange version of Swapi/Object with CustomScalarCodecs instead of ScalarCodecs generated by his code generation utility. I'm new to Elm, so costed me some time to make the Starwars.elm file work with properly generated classes, since even Id types in the repo example are not matching the generated types (Int vs String).
