npm i -D @graphql-codegen/typescript-graphql-request
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 graphql-request
ready-to-use SDK, which is fully-typed.
Config API Reference
rawRequest
type: boolean
default: false
By default, the request
method return the data
or errors
key from the response. If you need to access the extensions
key you can use the rawRequest
method.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-graphql-request'],
config: {
rawRequest: true
},
},
},
};
export default config;
extensionsType
type: string
default: any
Allows you to override the type for extensions when rawRequest
is enabled.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-graphql-request'],
config: {
rawRequest: true,
extensionsType: 'unknown'
},
},
},
};
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 (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.
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

generates: {
'path/to/file': {
// plugins...
config: {
namingConvention: {
typeNames: 'change-case-all#pascalCase',
transformUnderscore: true
}
},
},
},
};
export default config;
typesPrefix
type: string
default: (empty)
Prefixes all the generated types.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file': {
// plugins...
config: {
typesPrefix: 'I',
},
},
},
};
export default config;
typesSuffix
type: string
default: (empty)
Suffixes all the generated types.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file': {
// plugins...
config: {
typesSuffix: 'I',
},
},
},
};
export default config;
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: 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.
typescript
plugin and typescript-operations
as well in your configuration:Usage Example
For the given input:
query continents {
continents {
name
countries {
...CountryFields
}
}
}
fragment CountryFields on Country {
name
currency
}
It generates SDK you can import and wrap your GraphQLClient
instance, and get fully-typed SDK based on your operations:
import { GraphQLClient } from 'graphql-request'
import { getSdk } from './sdk' // THIS FILE IS THE GENERATED FILE
async function main() {
const client = new GraphQLClient('https://countries.trevorblades.com')
const sdk = getSdk(client)
const { continents } = await sdk.continents() // This is fully typed, based on the query
console.log(`GraphQL data:`, continents)
}
Simple Request Middleware
The generated sdk accepts an optional middleware function to wrap the requests the client
makes.
This can enable scenarios like request failure retries and logging at the sdk level.
To use middleware, just pass an SdkFunctionWrapper
as the second argument to getSdk
.
// `SdkFunctionWrapper` is a type we provide. `action` is the `client` request execution generated by this template. The wrapper MUST invoke `action()` and should return the promise returned by `action`, or its resolution.
type SdkFunctionWrapper = <T>(action: () => Promise<T>) => Promise<T>
Examples of Middleware
- This example shows a naive request timing logger.
const client = new GraphQLClient('')
const clientTimingWrapper: SdkFunctionWrapper = async <T>(action: () => Promise<T>): Promise<T> => {
const startTime = new Date()
const result = await action()
console.log('request duration (ms)', new Date() - startTime)
return result
}
const sdk = getSdk(client, clientTimingWrapper)
- This example uses polly-js to define a failure retry wrapper. (this is the use case for which I originally intended to add this capability)
const withRetries: RetryWrapper = <T>(action: () => Promise<T>) =>
polly()
.handle((err: Error) => {
warn('GraphqlClient:NetworkError', err)
return err.message.includes('connect ETIMEDOUT')
})
.waitAndRetry(3)
.executeForPromise(info => {
if (info.count === 3) {
error('GraphqlClient:MaxRetries', null, {
...info,
action: action.toString()
})
} else if (info.count > 0) {
warn('GraphqlClient:RetryingCall', null, {
...info,
action: action.toString()
})
}
return action()
})
const sdk = getSdk(client, withRetries)
