TypeScript Stencil Apollo

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.

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.


typescript-stencil-apollo plugin version
Using yarn
yarn add -D @graphql-codegen/typescript-stencil-apollo

API Reference


type: StencilComponentType default: functional

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


type: boolean default: false

Deprecated. Changes the documentMode to documentNode.


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

gqlImport: graphql.macro#gql
gqlImport: gatsby#graphql


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.


type: boolean default: false

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


type: boolean default: false

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


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.


type: string default: ``

Adds a suffix to generated operation result type names


type: string default: ``

Changes the GraphQL operations variables prefix.


type: string default: Document

Changes the GraphQL operations variables suffix.


type: string default: ``

Changes the GraphQL fragments variables prefix.


type: string default: FragmentDoc

Changes the GraphQL fragments variables suffix.


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.


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).


type: string default: ``

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.


type: string default: ``

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

documentMode: external
importDocumentNodeExternallyFrom: path/to/document-node-file
documentMode: external
importDocumentNodeExternallyFrom: near-operation-file


type: boolean default: false

This config adds PURE magic comment to the static variables to enforce treeshaking for your bundler.


type: boolean default: false

If set to true, it will enable support for parsing variables on fragments.


type: ScalarsMap

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


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 preserves 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


type: string default: ``

Prefixes all the generated types.

Usage Examples

typesPrefix: I


type: string default: ``

Suffixes all the generated types.

Usage Examples

typesSuffix: I


type: boolean default: false

Does not add __typename to the generated types, unless it was specified in the selection set.

Usage Examples

skipTypename: true


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

nonOptionalTypename: true


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 Example#

For the given input:

query Test {
feed {
repository {
owner {

We can use the generated code like this:

<TestComponent variables={...}>
