@graphql-codegen/typescript-react-apollo | Nov 24th, 2022 |
Installation
yarn add -D @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.

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

typesPrefix
typesSuffix
skipTypename
type: boolean
default: false
Does not add __typename
to the generated types, unless it was specified in the selection set.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file': {
// plugins...
config: {
skipTypename: true
},
},
},
};
export default config;
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...
config: {
useTypeImports: true
},
},
},
};
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: 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).
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
With React Hooks
For the given input:
query Test {
feed {
id
commentCount
repository {
full_name
html_url
owner {
avatar_url
}
}
}
}
And the following configuration:
import type { CodegenConfig } from '@graphql-codegen/cli'
const config: CodegenConfig = {
schema: 'YOUR_SCHEMA_HERE',
documents: './src/**/*.graphql',
generates: {
'./generated-types.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-react-apollo']
}
}
}
export default config
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:
import type { CodegenConfig } from '@graphql-codegen/cli'
const config: CodegenConfig = {
schema: 'YOUR_SCHEMA_HERE',
documents: './src/**/*.graphql',
generates: {
'./generated-types.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-react-apollo'],
config: {
withComponent: true
}
}
}
}
export default config
Generate HOC
Codegen also supports generating High-Order-Components (deprecated in @apollo/client
v3), you can turn it on this way:
import type { CodegenConfig } from '@graphql-codegen/cli'
const config: CodegenConfig = {
schema: 'YOUR_SCHEMA_HERE',
documents: './src/**/*.graphql',
generates: {
'./generated-types.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-react-apollo'],
config: {
withHOC: true
}
}
}
}
export default config
