TypeScript React Apollo

yarn add @graphql-codegen/typescript-react-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 React Apollo components and HOC with TypeScript typings.

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

Config API Reference#

defaultBaseOptions

type: object

hooksSuffix

type: string

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

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

type: boolean default: false

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

experimentalFragmentVariables

type: boolean default: false

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

strictScalars

type: boolean default: false

Makes scalars strict.

If scalars are found in the schema that are not defined in scalars an error will be thrown during codegen.

Usage Examples#

config: strictScalars: true
defaultScalarType

type: string default: any

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

Usage Examples#

config: defaultScalarType: unknown
scalars

type: ScalarsMap

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

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

typesPrefix

type: string default: (empty)

Prefixes all the generated types.

Usage Examples#

config: typesPrefix: I
typesSuffix

type: string default: (empty)

Suffixes all the generated types.

Usage Examples#

config: typesSuffix: I
skipTypename

type: boolean default: false

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

Usage Examples#

config: skipTypename: true
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#

config: nonOptionalTypename: true
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

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: InlineFragmentTypeOptions 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).

Usage Example#

With React Hooks#

For the given input:

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

And the following configuration:

schema: YOUR_SCHEMA_HERE documents: './src/**/*.graphql' generates: ./generated-types.ts: plugins: - typescript - typescript-operations - typescript-react-apollo

Codegen will pre-compile the GraphQL operation into a DocumentNode object, and generate a ready-to-use React Hook for each operation you have.

In your application code, you can import it from the generated file, and use the React Hook in your component code:

import { useTest } from './generated-types' export const MyComponent: React.FC = () => { const { data, error, loading } = useTest() return <div> ... </div> }

Generate Data Component#

Codegen also supports generating data Components (deprecated in @apollo/client v3), you can turn it on this way:

config: withComponent: true

Generate HOC#

Codegen also supports generating High-Order-Components (deprecated in @apollo/client v3), you can turn it on this way:

config: withHOC: true
