scala.js suppport for @graphql-codegen

@graphql-codgen is a plugin driven ecosystem of graphql code generators. It differs from the code generators included in the apollo platform.

These packages take a schema first approach versus a code first approach like caliban. There are multiple code generators depending on what you want to generate.

• @aappddeevv/graphql-codegen-scala-operations: Generate "client" operation code.
• @aappddeevv/graphql-codegen-scala-schema: Generate schema type code typically for the "server."
  • Prototype only.

You use the plugins like any other for @graphql-codgen so please see the instructions for that project.

The code generators create scala code that uses only basic scala.js constructs so there are no additional libraries to import. The generated code uses js.Array, js.UndefOr, and T | Null to translate graphql language constructs to scala.js code. You will probably want to use implicit conversions to help manage the data wrangling for your code.

This is a new project and the graphql spec is not fully supported. The current focus is on generating operations for the client with the target being the apollo graphql client although there is nothing specific to apollo in the generated code.

There is a package called @aappddeevv/graphql-codegen-scala on npm. Ignore it and use the npm packages listed above using the registry option listed below.
