Installation

npm i -D @graphql-codegen/typescript-stencil-apollo

This plugin generates Stencil Apollo functional components typings

It extends the basic TypeScript plugins: @graphql-codegen/typescript, @graphql-codegen/typescript-operations - and thus shares a similar configuration.

Config API Reference

componentType

type: StencilComponentType default: functional

Customize the output of the plugin - you can choose to generate a Component class or a function component.

Usage Examples

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

noGraphQLTag

type: boolean default: false

Deprecated. Changes the documentMode to documentNode.

gqlImport

type: string default: graphql-tag#gql

Customize from which module will gql be imported from. This is useful if you want to use modules other than graphql-tag, e.g. graphql.macro.

Usage Examples

graphql.macro

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {
       // plugins...
       config: {
         gqlImport: 'graphql.macro#gql'
       },
     },
   },
 };
 export default config;

Gatsby

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {
       // plugins...
       config: {
         gqlImport: 'gatsby#graphql'
       },
     },
   },
 };
 export default config;

documentNodeImport

type: string default: graphql#DocumentNode

Customize from which module will DocumentNode be imported from. This is useful if you want to use modules other than graphql, e.g. @graphql-typed-document-node.

noExport

type: boolean default: false

Set this configuration to true if you wish to tell codegen to generate code with no export identifier.

dedupeOperationSuffix

type: boolean default: false

Set this configuration to true if you wish to make sure to remove duplicate operation name suffix.

omitOperationSuffix

type: boolean default: false

Set this configuration to true if you wish to disable auto add suffix of operation name, like Query, Mutation, Subscription, Fragment.

operationResultSuffix

type: string default: (empty)

Adds a suffix to generated operation result type names

documentVariablePrefix

type: string default: (empty)

Changes the GraphQL operations variables prefix.

documentVariableSuffix

type: string default: Document

Changes the GraphQL operations variables suffix.

fragmentVariablePrefix

type: string default: (empty)

Changes the GraphQL fragments variables prefix.

fragmentVariableSuffix

type: string default: FragmentDoc

Changes the GraphQL fragments variables suffix.

documentMode

type: DocumentMode default: graphQLTag

Declares how DocumentNode are created:

• graphQLTag: graphql-tag or other modules (check gqlImport) will be used to generate document nodes. If this is used, document nodes are generated on client side i.e. the module used to generate this will be shipped to the client
• documentNode: document nodes will be generated as objects when we generate the templates.
• documentNodeImportFragments: Similar to documentNode except it imports external fragments instead of embedding them.
• external: document nodes are imported from an external file. To be used with importDocumentNodeExternallyFrom

Note that some plugins (like typescript-graphql-request) also supports string for this parameter.

optimizeDocumentNode

type: boolean default: true

If you are using documentNode: documentMode | documentNodeImportFragments, you can set this to true to apply document optimizations for your GraphQL document. This will remove all "loc" and "description" fields from the compiled document, and will remove all empty arrays (such as directives, arguments and variableDefinitions).

importOperationTypesFrom

type: string default: (empty)

This config is used internally by presets, but you can use it manually to tell codegen to prefix all base types that it's using. This is useful if you wish to generate base types from typescript-operations plugin into a different file, and import it from there.

importDocumentNodeExternallyFrom

type: string default: (empty)

This config should be used if documentMode is external. This has 2 usage:

• any string: This would be the path to import document nodes from. This can be used if we want to manually create the document nodes e.g. Use graphql-tag in a separate file and export the generated document

• 'near-operation-file': This is a special mode that is intended to be used with near-operation-file preset to import document nodes from those files. If these files are .graphql files, we make use of webpack loader.

Usage Examples

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {
       // plugins...
       config: {
         documentMode: 'external',
         importDocumentNodeExternallyFrom: 'path/to/document-node-file',
       },
     },
   },
 };
 export default config;

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {
       // plugins...
       config: {
         documentMode: 'external',
         importDocumentNodeExternallyFrom: 'near-operation-file',
       },
     },
   },
 };
 export default config;

pureMagicComment

type: boolean default: false

       config: {
         strictScalars: true,
       },
     },
   },
 };
 export default config;

defaultScalarType

type: string default: any

Allows you to override the type that unknown scalars will have.

Usage Examples

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {
       // plugins...
       config: {
         defaultScalarType: 'unknown'
       },
     },
   },
 };
 export default config;

scalars

type: ScalarsMap

Extends or overrides the built-in scalars and custom GraphQL scalars to a custom type.

Usage Examples

 import type { CodegenConfig } from '@graphql-codegen/cli';
 
 const config: CodegenConfig = {
   // ...
   generates: {
     'path/to/file': {
       // plugins...
       config: {
         scalars: {
           DateTime: 'Date',
           JSON: '{ [key: string]: any }',
         }
       },
     },
   },
 };
 export default config;

namingConvention

type: NamingConvention default: change-case-all#pascalCase

Allow you to override the naming convention of the output. You can either override all namings, or specify an object with specific custom naming convention per output. The format of the converter must be a valid module#method. Allowed values for specific output are: typeNames, enumValues. You can also use "keep" to keep all GraphQL names as-is. Additionally, you can set transformUnderscore to true if you want to override the default behavior, which is to preserve underscores.

Available case functions in change-case-all are camelCase, capitalCase, constantCase, dotCase, headerCase, noCase, paramCase, pascalCase, pathCase, sentenceCase, snakeCase, lowerCase, localeLowerCase, lowerCaseFirst, spongeCase, titleCase, upperCase, localeUpperCase and upperCaseFirst See more

nonOptionalTypename

type: boolean default: false

Automatically adds __typename field to the generated types, even when they are not specified in the selection set, and makes it non-optional

Usage Examples

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

useTypeImports

type: boolean default: false

Will use import type {} rather than import {} when importing only types. This gives compatibility with TypeScript's "importsNotUsedAsValues": "error" option

Usage Examples

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

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

dedupeFragments

type: boolean default: false

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: string 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

For the given input:

query Test {
  feed {
    id
    commentCount
    repository {
      full_name
      html_url
      owner {
        avatar_url
      }
    }
  }
}

We can use the generated code like this:

<TestComponent variables={...}>
  …
</TestComponent>
