Support for multiple schemas

[louy]

Hi there,

Are there any plans to introduce multi-instance support without having to create separate tsconfig files?

Something like gql.tada does, where it allows you to configure the plugin multiple times (via ts-config.json's compilerOptions.plugins).

Reason: I've had the same issue multiple times, where I'd want to expose different schema on different endpoints for different audiences, but code them in the same codebase (monolith).

For example: When a product has multiple target audiences, with different login mechanisms, and completely different functionality.

• a B2B and B2C product, with different sets of APIs and users/auth
• an end-user vs an admin portal API

Right now, Grats scans the whole TypeScript project for docblock tags. Before we can talk about multiple config's, I think we would first need some mechanism whereby it would ignore some files?

How are you imagining that part working?

I managed to get this to work by having multiple tsconfig files, and using include and exclude.

Then, I run grats --tsconfig projectA/tsconfig.json, grats --tsconfig projectB/tsconfig.json, etc

I think for grats, it would be great if it can take an array of configurations, and respect include/exclude options (as filters on top of the tsconfig options).

E.g.

{
  "extends": "@tsconfig/node20",
  "include": ["src/**/*.ts"],
  "exclude": ["**/*.test.*"],
  "grats": [
    {
      "include": ["**/projectA/**"], 
      // Include will only apply to files already in the tsconfig project scope 
      // (i.e. will only look at `src/` and exclude test files. 
      // However, when include is specified anything not in the list of patterns here is excluded.
      "graphqlSchema": "../__generated__/projectA-schema.graphql",
      "tsSchema": "../__generated__/projectA-schema.ts",
      "nullableByDefault": false,
      "importModuleSpecifierEnding": ".js"
    },
    {
      "exclude": ["**/projectA/**/*"], 
      // Not specifying `include` will include everything in the project by default, 
      // and then `exclude` rules will be applied on top
      "graphqlSchema": "../__generated__/projectB-schema.graphql",
      "tsSchema": "../__generated__/projectB-schema.ts",
      "importModuleSpecifierEnding": ".js"
    }
  ]
}
