  • #9375 ba84a3a27 Thanks @eddeee888! - Implement Scalars with input/output types

    In GraphQL, Scalar types can be different for client and server. For example, given the native GraphQL ID:

    • A client may send string or number in the input
    • A client receives string in its selection set (i.e output)
    • A server receives string in the resolver (GraphQL parses string or number received from the client to string)
    • A server may return string or number (GraphQL serializes the value to string before sending it to the client )

    Currently, we represent every Scalar with only one type. This is what codegen generates as base type: 

    export type Scalars = {
  ID: string;
};

    Then, this is used in both input and output type e.g. 

    export type Book = {
  __typename?: 'Book';
  id: Scalars['ID']; // Output's ID can be `string` 👍
};

export type QueryBookArgs = {
  id: Scalars['ID']; // Input's ID can be `string` or `number`. However, the type is only `string` here 👎
};

    This PR extends each Scalar to have input and output: 

    export type Scalars = {
  ID: {
    input: string | number;
    output: string;
  };
};

    Then, each input/output GraphQL type can correctly refer to the correct input/output scalar type: 

    export type Book = {
  __typename?: 'Book';
  id: Scalars['ID']['output']; // Output's ID can be `string` 👍
};

export type QueryBookArgs = {
  id: Scalars['ID']['input']; // Input's ID can be `string` or `number` 👍
};

    Note that for typescript-resolvers, the type of ID needs to be inverted. However, the referenced types in GraphQL input/output types should still work correctly: 

    export type Scalars = {
  ID: {
    input: string;
    output: string | number;
  }
}

export type Book = {
  __typename?: "Book";
  id: Scalars["ID"]['output']; // Resolvers can return `string` or `number` in ID fields 👍
};

export type QueryBookArgs = {
  id: Scalars["ID"]['input']; // Resolvers receive `string` in ID fields 👍
};

export type ResolversTypes = {
  ID: ID: ResolverTypeWrapper<Scalars['ID']['output']>; // Resolvers can return `string` or `number` in ID fields 👍
}

export type ResolversParentTypes = {
  ID: Scalars['ID']['output']; // Resolvers receive `string` or `number` from parents 👍
};

    Config changes:

    1. Scalars option can now take input/output types: 
    config: {
  scalars: {
    ID: {
      input: 'string',
      output: 'string | number'
    }
  }
}
    1. If a string is given (instead of an object with input/output fields), it will be used as both input and output types: 
    config: {
  scalars: {
    ID: 'string'; // This means `string` will be used for both ID's input and output types
  }
}
    1. BREAKING CHANGE: External module Scalar types need to be an object with input/output fields 
    config: {
  scalars: {
    ID: './path/to/scalar-module';
  }
}

    If correctly, wired up, the following will be generated: 

    // Previously, imported `ID` type can be a primitive type, now it must be an object with input/output fields
import { ID } from './path/to/scalar-module';

export type Scalars = {
  ID: { input: ID['input']; output: ID['output'] };
};

    BREAKING CHANGE: This changes Scalar types which could be referenced in other plugins. If you are a plugin maintainer and reference Scalar, please update your plugin to use the correct input/output types.

Minor Changes

  • #9196 3848a2b73 Thanks @beerose! - Add @defer directive support

    When a query includes a deferred fragment field, the server will return a partial response with the non-deferred fields first, followed by the remaining fields once they have been resolved.

    Once start using the @defer directive in your queries, the generated code will automatically include support for the directive. 

    // src/index.tsx
import { graphql } from './gql';
const OrdersFragment = graphql(`
  fragment OrdersFragment on User {
    orders {
      id
      total
    }
  }
`);
const GetUserQuery = graphql(`
  query GetUser($id: ID!) {
    user(id: $id) {
      id
      name
      ...OrdersFragment @defer
    }
  }
`);

    The generated type for GetUserQuery will have information that the fragment is incremental, meaning it may not be available right away. 

    // gql/graphql.ts
export type GetUserQuery = { __typename?: 'Query'; id: string; name: string } & ({
  __typename?: 'Query';
} & {
  ' $fragmentRefs'?: { OrdersFragment: Incremental<OrdersFragment> };
});

    Apart from generating code that includes support for the @defer directive, the Codegen also exports a utility function called isFragmentReady. You can use it to conditionally render components based on whether the data for a deferred
    fragment is available: 

    const OrdersList = (props: { data: FragmentType<typeof OrdersFragment> }) => {
  const data = useFragment(OrdersFragment, props.data);
  return (
    // render orders list
  )
};

function App() {
  const { data } = useQuery(GetUserQuery);
  return (
    {data && (
      <>
        {isFragmentReady(GetUserQuery, OrdersFragment, data)
					&& <OrdersList data={data} />}
      </>
    )}
  );
}
export default App;

  • #9339 50471e651 Thanks @AaronMoat! - Add excludeTypes config to resolversNonOptionalTypename

    This disables the adding of __typename in resolver types for any specified typename. This could be useful e.g. if you're wanting to enable this for all new types going forward but not do a big migration.

    Usage example: 

    const config: CodegenConfig = {
  schema: 'src/schema/**/*.graphql',
  generates: {
    'src/schema/types.ts': {
      plugins: ['typescript', 'typescript-resolvers'],
      config: {
        resolversNonOptionalTypename: {
          unionMember: true,
          excludeTypes: ['MyType'],
        },
      },
    },
  },
};

  • #9229 5aa95aa96 Thanks @eddeee888! - Use generic to simplify ResolversUnionTypes

    This follows the ResolversInterfaceTypes's approach where the RefType generic is used to refer back to ResolversTypes or ResolversParentTypes in cases of nested Union types

  • #9304 e1dc75f3c Thanks @esfomeado! - Added support for disabling suffixes on Enums.

  • #9229 5aa95aa96 Thanks @eddeee888! - Extract interfaces to ResolversInterfaceTypes and add to resolversNonOptionalTypename

    1. ResolversInterfaceTypes is a new type that keeps track of a GraphQL interface and its implementing types.

    For example, consider this schema: 

    extend type Query {
  character(id: ID!): CharacterNode
}

interface CharacterNode {
  id: ID!
}

type Wizard implements CharacterNode {
  id: ID!
  screenName: String!
  spells: [String!]!
}

type Fighter implements CharacterNode {
  id: ID!
  screenName: String!
  powerLevel: Int!
}

    The generated types will look like this: 

    export type ResolversInterfaceTypes<RefType extends Record<string, unknown>> = {
  CharacterNode: Fighter | Wizard;
};

export type ResolversTypes = {
  // other types...
  CharacterNode: ResolverTypeWrapper<ResolversInterfaceTypes<ResolversTypes>['CharacterNode']>;
  Fighter: ResolverTypeWrapper<Fighter>;
  Wizard: ResolverTypeWrapper<Wizard>;
  // other types...
};

export type ResolversParentTypes = {
  // other types...
  CharacterNode: ResolversInterfaceTypes<ResolversParentTypes>['CharacterNode'];
  Fighter: Fighter;
  Wizard: Wizard;
  // other types...
};

    The RefType generic is used to reference back to ResolversTypes and ResolversParentTypes in some cases such as field returning a Union.

    1. resolversNonOptionalTypename also affects ResolversInterfaceTypes

    Using the schema above, if we use resolversNonOptionalTypename option: 

    const config: CodegenConfig = {
  schema: 'src/schema/**/*.graphql',
  generates: {
    'src/schema/types.ts': {
      plugins: ['typescript', 'typescript-resolvers'],
      config: {
        resolversNonOptionalTypename: true, // Or `resolversNonOptionalTypename: { interfaceImplementingType: true }`
      },
    },
  },
};

    Then, the generated type looks like this: 

    export type ResolversInterfaceTypes<RefType extends Record<string, unknown>> = {
  CharacterNode: (Fighter & { __typename: 'Fighter' }) | (Wizard & { __typename: 'Wizard' });
};

export type ResolversTypes = {
  // other types...
  CharacterNode: ResolverTypeWrapper<ResolversInterfaceTypes<ResolversTypes>['CharacterNode']>;
  Fighter: ResolverTypeWrapper<Fighter>;
  Wizard: ResolverTypeWrapper<Wizard>;
  // other types...
};

export type ResolversParentTypes = {
  // other types...
  CharacterNode: ResolversInterfaceTypes<ResolversParentTypes>['CharacterNode'];
  Fighter: Fighter;
  Wizard: Wizard;
  // other types...
};

    1. ResolversInterfaceTypes is a new type that keeps track of a GraphQL interface and its implementing types.

    For example, consider this schema: 

    extend type Query {
  character(id: ID!): CharacterNode
}

interface CharacterNode {
  id: ID!
}

type Wizard implements CharacterNode {
  id: ID!
  screenName: String!
  spells: [String!]!
}

type Fighter implements CharacterNode {
  id: ID!
  screenName: String!
  powerLevel: Int!
}

    The generated types will look like this: 

    export type ResolversInterfaceTypes<RefType extends Record<string, unknown>> = {
  CharacterNode: Fighter | Wizard;
};

export type ResolversTypes = {
  // other types...
  CharacterNode: ResolverTypeWrapper<ResolversInterfaceTypes<ResolversTypes>['CharacterNode']>;
  Fighter: ResolverTypeWrapper<Fighter>;
  Wizard: ResolverTypeWrapper<Wizard>;
  // other types...
};

export type ResolversParentTypes = {
  // other types...
  CharacterNode: ResolversInterfaceTypes<ResolversParentTypes>['CharacterNode'];
  Fighter: Fighter;
  Wizard: Wizard;
  // other types...
};

    The RefType generic is used to reference back to ResolversTypes and ResolversParentTypes in some cases such as field returning a Union.

    1. resolversNonOptionalTypename also affects ResolversInterfaceTypes

    Using the schema above, if we use resolversNonOptionalTypename option: 

    const config: CodegenConfig = {
  schema: 'src/schema/**/*.graphql',
  generates: {
    'src/schema/types.ts': {
      plugins: ['typescript', 'typescript-resolvers'],
      config: {
        resolversNonOptionalTypename: true, // Or `resolversNonOptionalTypename: { interfaceImplementingType: true }`
      },
    },
  },
};

    Then, the generated type looks like this: 

    export type ResolversInterfaceTypes<RefType extends Record<string, unknown>> = {
  CharacterNode: (Fighter & { __typename: 'Fighter' }) | (Wizard & { __typename: 'Wizard' });
};

export type ResolversTypes = {
  // other types...
  CharacterNode: ResolverTypeWrapper<ResolversInterfaceTypes<ResolversTypes>['CharacterNode']>;
  Fighter: ResolverTypeWrapper<Fighter>;
  Wizard: ResolverTypeWrapper<Wizard>;
  // other types...
};

  • #9196 3848a2b73 Thanks @beerose! - Add @defer directive support

    When a query includes a deferred fragment field, the server will return a partial response with the non-deferred fields first, followed by the remaining fields once they have been resolved.

    Once start using the @defer directive in your queries, the generated code will automatically include support for the directive. 

    // src/index.tsx
import { graphql } from './gql';
const OrdersFragment = graphql(`
  fragment OrdersFragment on User {
    orders {
      id
      total
    }
  }
`);
const GetUserQuery = graphql(`
  query GetUser($id: ID!) {
    user(id: $id) {
      id
      name
      ...OrdersFragment @defer
    }
  }
`);

    The generated type for GetUserQuery will have information that the fragment is incremental, meaning it may not be available right away. 

    // gql/graphql.ts
export type GetUserQuery = { __typename?: 'Query'; id: string; name: string } & ({
  __typename?: 'Query';
} & {
  ' $fragmentRefs'?: { OrdersFragment: Incremental<OrdersFragment> };
});

    Apart from generating code that includes support for the @defer directive, the Codegen also exports a utility function called isFragmentReady. You can use it to conditionally render components based on whether the data for a deferred
    fragment is available: 

    const OrdersList = (props: { data: FragmentType<typeof OrdersFragment> }) => {
  const data = useFragment(OrdersFragment, props.data);
  return (
    // render orders list
  )
};

function App() {
  const { data } = useQuery(GetUserQuery);
  return (
    {data && (
      <>
        {isFragmentReady(GetUserQuery, OrdersFragment, data)
					&& <OrdersList data={data} />}
      </>
    )}
  );
}

  • #9375 ba84a3a27 Thanks @eddeee888! - Implement Scalars with input/output types

    In GraphQL, Scalar types can be different for client and server. For example, given the native GraphQL ID:

    • A client may send string or number in the input
    • A client receives string in its selection set (i.e output)
    • A server receives string in the resolver (GraphQL parses string or number received from the client to string)
    • A server may return string or number (GraphQL serializes the value to string before sending it to the client )

    Currently, we represent every Scalar with only one type. This is what codegen generates as base type: 

    export type Scalars = {
  ID: string;
};

    Then, this is used in both input and output type e.g. 

    export type Book = {
  __typename?: 'Book';
  id: Scalars['ID']; // Output's ID can be `string` 👍
};

export type QueryBookArgs = {
  id: Scalars['ID']; // Input's ID can be `string` or `number`. However, the type is only `string` here 👎
};

    This PR extends each Scalar to have input and output: 

    export type Scalars = {
  ID: {
    input: string | number;
    output: string;
  };
};

    Then, each input/output GraphQL type can correctly refer to the correct input/output scalar type: 

    export type Book = {
  __typename?: 'Book';
  id: Scalars['ID']['output']; // Output's ID can be `string` 👍
};

export type QueryBookArgs = {
  id: Scalars['ID']['input']; // Input's ID can be `string` or `number` 👍
};

    Note that for typescript-resolvers, the type of ID needs to be inverted. However, the referenced types in GraphQL input/output types should still work correctly: 

    export type Scalars = {
  ID: {
    input: string;
    output: string | number;
  }
}

export type Book = {
  __typename?: "Book";
  id: Scalars["ID"]['output']; // Resolvers can return `string` or `number` in ID fields 👍
};

export type QueryBookArgs = {
  id: Scalars["ID"]['input']; // Resolvers receive `string` in ID fields 👍
};

export type ResolversTypes = {
  ID: ID: ResolverTypeWrapper<Scalars['ID']['output']>; // Resolvers can return `string` or `number` in ID fields 👍
}

export type ResolversParentTypes = {
  ID: Scalars['ID']['output']; // Resolvers receive `string` or `number` from parents 👍
};

    Config changes:

    1. Scalars option can now take input/output types: 
    config: {
  scalars: {
    ID: {
      input: 'string',
      output: 'string | number'
    }
  }
}
    1. If a string is given (instead of an object with input/output fields), it will be used as both input and output types: 
    config: {
  scalars: {
    ID: 'string'; // This means `string` will be used for both ID's input and output types
  }
}
    1. BREAKING CHANGE: External module Scalar types need to be an object with input/output fields 
    config: {
  scalars: {
    ID: './path/to/scalar-module';
  }
}

    If correctly, wired up, the following will be generated: 

    // Previously, imported `ID` type can be a primitive type, now it must be an object with input/output fields
import { ID } from './path/to/scalar-module';

export type Scalars = {
  ID: { input: ID['input']; output: ID['output'] };
};

    BREAKING CHANGE: This changes Scalar types which could be referenced in other plugins. If you are a plugin maintainer and reference Scalar, please update your plugin to use the correct input/output types.
