Understanding how to work with `Effect` and `Layer` in the Effect Typescript library can be a bit...

export class Drizzle extends Context.Tag(CONTEXT_KEY)<Drizzle, Service>() {
    static layerFromEnv() {
        return Effect.gen(function* () {
            const config = yield* Config.all({ databaseUrl: Config.redacted('DATABASE_URL') })
            return PgDrizzle.layerWithConfig({ casing: 'snake_case' }).pipe(
                Layer.provide(PgClient.layer({ url: config.databaseUrl })),
            )
        })
    }
}

export class Repository extends Context.Tag(CONTEXT_KEY)<
    Repository,
    Service
>() {
    static layerWithoutDependencies() {
        return Layer.effect(this, createService())
    }

    static layer() {
        return this.layerWithoutDependencies().pipe(Effect.provide(Drizzle.layerFromEnv()))
    }
}
