scala-relay-compiler

scala-relay-compiler

The purpose of this project is to generate Scala (sjs) bindings for the relay-compiler. Typically the relay-compiler generates flow bindings along with the compiled queries. This project replaces that generation and outputs js.native traits instead.

Example

$ ./bin/scala-relay-compiler.js --src example/src/ --schema example/schema.graphql --out example/out/

Features

• Handles names elegantly by scoping them to the companion object.
• Handles first layer of spreading, right now we spit out js.| to join disjoint fields, even though in fact they are not disjoint, they are a union, however, this requires a fix later down the line.
• @sjs(with:Boolean!) basically this allows us to control from a fragment spread level whether to combine the fields as an js.| or using with. With has more compile time constraints where js.| is easier to generate.

TODO

• Med: Fix InlineFragments so they work properly. Right now we just really don't handle them.
• Big: Fix spreading so it goes recursively? Right now spreading is difficult because the types that are mixed in couple potentially conflict
  • Med: Make it work recursively
  • Med: Generate the necessary class depth.
  • Big: How to handle traversing since the order of the frags are unable to to be changed.
• Med: Handle connections and edges with a superclass.
