The purpose of this project is to emit an artifact that:

• Includes the schema files, so that it can be referenced by projects downstream to validate and generate queries.
• Includes the types generated from those schemas.
• Is cross compiled for the JVM and JS.

Contains:

• Schema files in resources (eg: ObservationDB.graphql). They can be updated with fetchODBSchema.mjs. Use the flake.nix with nix develop, and run npm install to use.
• Templates (eg: ObservationDB.scala) to map schema scalars and other types to Scala types.

This is the project that is published.

Contains:

• Full-fledged generated schema source (using clue's generator), as managed source.
• Utilities, encoders, decoders, etc. to work with the schema.

Also adds templates's resources as this project's resources, so that schema files are included in the published artifacts.

In downstream projects using clue, to generate code for queries with scalafix GraphQLGen, the following settings are needed:

• In build.sbt:

  scalafixDependencies += "edu.gemini" %% "lucuma-schemas" % lucumaSchemasVersion,
  libraryDependencies += "edu.gemini" %% "lucuma-schemas" % lucumaSchemasVersion,

The first line makes the schema file available to the scalafix rule. The second one adds the classes from this project as a regular runtime dependency.

• In .scalafix.conf:

  GraphQLGen.schemaDirs=["/lucuma/schemas"]
