⚠️

Usage Requirements In order to use this GraphQL Codegen plugin, please make sure that you have GraphQL operations (query / mutation / subscription and fragment) set as documents: … in your codegen.yml.

Without loading your GraphQL operations (query, mutation, subscription and fragment), you won't see any change in the generated output.

💡

Watch Episode #26 of graphql.wtf for a quick introduction to this plugin and its features:

💡

More weekly episodes are available in graphql.wtf by Jamie Barton.

This plugin generates TypeScript signature for resolve functions of your GraphQL API. You can use this plugin to generate simple resolvers signature based on your GraphQL types, or you can change its behavior be providing custom model types (mappers).

You can find a blog post explaining the usage of this plugin here: https://the-guild.dev/blog/better-type-safety-for-resolvers-with-graphql-codegen

Config API Reference

useIndexSignature

type: boolean default: false

Adds an index signature to any generates resolver.

Usage Examples

codegen.ts

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file.ts': {
       plugins: ['typescript', 'typescript-resolvers'],
       config: {
         useIndexSignature: true
       },
     },
   },
 };
 export default config;

noSchemaStitching

type: boolean default: true

Disables/Enables Schema Stitching support. By default, the resolver signature does not include the support for schema-stitching. Set to false to enable that.

Usage Examples

codegen.ts

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file.ts': {
       plugins: ['typescript', 'typescript-resolvers'],
       config: {
         noSchemaStitching: false
       },
     },
   },
 };
 export default config;

wrapFieldDefinitions

type: boolean default: true

Set to true in order to wrap field definitions with FieldWrapper. This is useful to allow return types such as Promises and functions. Needed for compatibility with federation: true when

customResolveInfo

type: string default: graphql#GraphQLResolveInfo

You can provide your custom GraphQLResolveInfo instead of the default one from graphql-js

Usage Examples

codegen.ts

 import type { CodegenConfig } from '@graphql-codegen/cli';

   // ...
   generates: {
     'path/to/file.ts': {
       plugins: ['typescript', 'typescript-resolvers'],
       config: {
         customResolveInfo: './my-types#MyResolveInfo'
       },
     },
   },
 };
 export default config;

customResolverFn

type: string default: (parent: TParent, args: TArgs, context: TContext, info: GraphQLResolveInfo) => Promise<TResult> | TResult

You can provide your custom ResolveFn instead the default. It has to be a type that uses the generics <TResult, TParent, TContext, TArgs>

       },
     },
   },
 };
 export default config;

rootValueType

type: string

Use this configuration to set a custom type for the rootValue, and it will affect resolvers of all root types (Query, Mutation and Subscription), without the need to override it using generics each time. If you wish to use an external type and import it from another file, you can use add plugin and add the required import statement, or you can use both module#type or module#namespace#type syntax.

       },
     },
   },
 };
 export default config;

directiveContextTypes

type: Array_1

Use this to set a custom type for a specific field context decorated by a directive. It will only affect the targeted resolvers. You can either use Field.Path#ContextTypeName or Field.Path#ExternalFileName#ContextTypeName

           Book: './my-models#Collections',
         }
       },
     },
   },
 };
 export default config;

defaultMapper

type: string

Allow you to set the default mapper when it's not being override by mappers or generics. You can specify a type name, or specify a string in module#type or module#namespace#type format. The default value of mappers is the TypeScript type generated by typescript package.

Wrap default types with Partial

You can also specify a custom wrapper for the original type, without overriding the original generated types, use {T} to specify the identifier. (for flow, use $Shape<{T}>)

codegen.ts

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {

 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {

Removes fragment duplicates for reducing data transfer. It is done by removing sub-fragments imports from fragment definition Instead - all of them are imported to the Operation node.

inlineFragmentTypes

type: InlineFragmentTypeOptions_1 default: inline

Whether fragment types should be inlined into other operations. "inline" is the default behavior and will perform deep inlining fragment types within operation type definitions. "combine" is the previous behavior that uses fragment type references without inlining the types (and might cause issues with deeply nested fragment that uses list types).

emitLegacyCommonJSImports

type: boolean default: true

Emit legacy common js imports. Default it will be true this way it ensure that generated code works with non-compliant bundlers.

Usage Example

💡

Quick Start with typescript-resolvers

You can find a blog post we wrote about using and customizing this plugin here

Run graphql-codegen as usual, with this new plugin:

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const config: CodegenConfig = {
  schema: 'schema.json',
  generates: {
    './src/resolvers-types.ts': {
      plugins: ['typescript', 'typescript-resolvers']
    }
  }
}
export default config

Import the types from the generated file and use in the resolver:

import { Resolvers } from './resolvers-types'
 
export const resolvers: Resolvers = {
  Query: {
    myQuery: (root, args, context) => {}
  }
}

This will make the resolver fully typed and compatible with typescript compiler, including the handler's arguments and return value.

Generated resolvers can be passed directly into graphql-tools makeExecutableSchema function.

Integration with Apollo-Server

By default apollo-server will not work with generated resolvers signature.

If you are using Apollo Server with TypeScript, note that you need to set useIndexSignature: true in your config, in order to add a compatible index signature (more info).

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const config: CodegenConfig = {
  generates: {
    './resolvers-types.ts': {
      config: {
        useIndexSignature: true
      },
      plugins: ['typescript', 'typescript-resolvers']
    }
  }
}
export default config

If you wish to have an easy start, and have the ability to use resolvers chaining without models types, you can also add to your config defaultMapper: Partial<{T}>. This will allow you to return partial types in your resolvers.

Use Your Model Types (`mappers`)

If you wish to use your custom model types, codegen allow you to use mappers feature to map GraphQL types to your custom model types. You can find an article explaining how to use mappers here.

Here's the basic example of using it:

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const config: CodegenConfig = {
  schema: 'schema.graphql',
  generates: {
    './resolvers-types.ts': {
      config: {
        contextType: 'models#MyContextType',
        mappers: {
          User: './models#UserModel',
          Profile: './models#UserProfile'
        }
      },
      plugins: ['typescript', 'typescript-resolvers']
    }
  }
}
export default config

Enum Resolvers

Apollo-Server and schemas built with graphql-tools supports creating resolvers for GraphQL enums.

This is helpful because you can have internal values that are different from the public enum values, and you can use the internal values in your resolvers.

Codegen allows you to specify either mappers or enumValues to map enums in your resolvers, and if you are using it for enums, you'll get a resolver signature for the enum resolvers as well.

Usage Example

With the following schema:

type Query {
  favoriteColor: Color!
}
 
enum Color {
  RED
  BLUE
}

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const config: CodegenConfig = {
  schema: 'schema.graphql',
  generates: {
    './resolvers-types.ts': {
      config: {
        enumValues: {
          Color: './enums#ColorsCode'
        }
      },
      plugins: ['typescript', 'typescript-resolvers']
    }
  }
}
export default config

enums.ts

export enum ColorsCode {
  MY_RED = '#FF0000',
  MY_BLUE = '#0000FF'
}

resolvers.ts

import { Resolvers } from './resolvers-types'
import { ColorsCode } from './enums'
 
const resolvers: Resolvers = {
  Color: {
    RED: ColorsCode.MY_RED,
    BLUE: ColorsCode.MY_BLUE
  },
  Query: {
    favoriteColor: () => ColorsCode.MY_RED // Now you cn return this, and it will be mapped to your actual GraphQL enum
  }
}

You can also define the same with explicit enum values:

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const config: CodegenConfig = {
  schema: 'schema.graphql',
  generates: {
    './resolvers-types.ts': {
      config: {
        enumValues: {
          Color: {
            RED: '#FF0000',
            BLUE: '#0000FF'
          }
        }
      },
      plugins: ['typescript', 'typescript-resolvers']
    }
  }
}
export default config

Or, with mappers:

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const config: CodegenConfig = {
  schema: 'schema.graphql',
  generates: {
    './resolvers-types.ts': {
      config: {
        mappers: {
          Color: './enums#ColorsCode'
        }
      },
      plugins: ['typescript', 'typescript-resolvers']
    }
  }
}
export default config

Defined shared mappers across configurations

In some case, you might want to share some common mappers between many output file configurations.

To do so, you can leverage the YAML references features as follow:

codegen.ts

import type { CodegenConfig } from '@graphql-codegen/cli'
 
const sharedMappers = {
  ID: 'IDType'
}
 
const config: CodegenConfig = {
  schema: 'schema.graphql',
  documents: 'src/*.ts',
  generates: {
    'resolvers-types-1.ts': {
      plugins: ['typescript', 'typescript-resolvers'],
      config: {
        mappers: {
          ...sharedMappers,
          String: 'StringType'
        }
      }
    },
    'resolvers-types-2.ts': {
      plugins: ['typescript', 'typescript-resolvers'],
      config: {
        mappers: {
          ...sharedMappers,
          String: 'StringType'
        }
      }
    }
  }
}
export default config

The above configuration will provide the ID type mapping to both resolvers-types-1.ts and resolvers-types-2.ts files.

The complete example is available here: codegen-repros/reusable-mappers

You can also achieve a similar reusable mappers configuration by providing a TypeScript or JavaScript file configuration.
