Installation
npm i -D @graphql-codegen/typescript-vue-apollo-smart-ops
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 Vue Apollo Smart Query, Smart Subscription and mutation operation functions with TypeScript typings.
This plugin relies on some helper functions and types from the vue-apollo-smart-ops
package. That package also adds
some optional functionality for improved error handling in Vue Apollo operations which can be configured in the
generated code from this plugin.
It extends the basic TypeScript plugins: @graphql-codegen/typescript
, @graphql-codegen/typescript-operations
-
and thus shares a similar configuration.
Config API Reference
withSmartOperationFunctions
type: boolean
default: true
Customize the output by enabling/disabling the generated Vue Apollo Smart Operations functions.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
withSmartOperationFunctions: true
},
},
},
};
export default config;
vueApolloOperationFunctionsImportFrom
type: string
default: vue-apollo-smart-ops
The typescript-vue-apollo-smart-ops
plugin requires three functions that are used to define your
query, subscription and mutation operation functions:
createMutationFunction
createSmartQueryOptionsFunction
createSmartSubscriptionOptionsFunction
By default, these functions are provided by the vue-apollo-smart-ops
package, but you can substitute
your own import path if you want to replace them with other implementations.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueApolloOperationFunctionsImportFrom: 'vue-apollo-smart-ops'
},
},
},
};
export default config;
vueApolloErrorType
type: string
default: ApolloError
The operation functions generated by typescript-vue-apollo-smart-ops
include some functionality for
error handling. This configuration parameter allows you to customise the name of the error type that
will be used. The default is to use ApolloError
from the apollo-client
package.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueApolloErrorType: 'ApolloError',
vueApolloErrorTypeImportFrom: 'apollo-client'
},
},
},
};
export default config;
vueApolloErrorTypeImportFrom
type: string
default: vue-apollo-smart-ops
The operation functions generated by typescript-vue-apollo-smart-ops
include some functionality for
error handling. This configuration parameter allows you to customise the package where the error type
will be imported from. The default is to use ApolloError
from the apollo-client
package.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueApolloErrorType: 'ApolloError',
vueApolloErrorTypeImportFrom: 'apollo-client'
},
},
},
};
export default config;
vueApolloErrorHandlerFunction
type: string
default: undefined
The operation functions generated by typescript-vue-apollo-smart-ops
include some functionality for
error handling. You may supply an error handler function that will be called when an error occurs in
a query, subscription or mutation operation. This function should implement the
ApolloOperationErrorHandlerFunction
interface from vue-apollo-smart-ops
package. You can
have a custom handler in your app that shows a notification to the user, for example. If unspecified,
this functionality will be disabled and errors handled (or not) by Vue Apollo in the normal way.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueApolloErrorHandlerFunction: 'handleApolloError',
vueApolloErrorHandlerFunctionImportFrom: './src/handleApolloError.ts',
},
},
},
};
export default config;
vueApolloErrorHandlerFunctionImportFrom
type: string
default: undefined
The import path where vueApolloErrorHandlerFunction
should be imported from. Can be a package name
or a local file path (anything that works in an import statement).
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueApolloErrorHandlerFunction: 'handleApolloError',
vueApolloErrorHandlerFunctionImportFrom: './src/handleApolloError.ts',
},
},
},
};
export default config;
vueAppType
type: string
default: undefined
The operation functions generated by typescript-vue-apollo-smart-ops
include some functionality for
error handling. When an error occurs, the Vue app instance is passed to the error handler. You can
customise the expected type of the app object. For example, a Nuxt.js app might use NuxtApp
from
@nuxt/types/app
instead. When unspecified, the default type is Vue
from vue/types/vue
.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueAppType: 'Vue',
vueAppTypeImportFrom: 'vue/types/vue'
},
},
},
};
export default config;
vueAppTypeImportFrom
type: string
default: undefined
The import path where vueAppType
should be imported from. Can be a package name or a local file path
(anything that works in an import statement).
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
vueAppType: 'Vue',
vueAppTypeImportFrom: 'vue/types/vue'
},
},
},
};
export default config;
addDocBlocks
type: boolean
default: true
Allows you to enable/disable the generation of docblocks in generated code. Some IDE’s (like VSCode) add extra inline information with docblocks, you can disable this feature if your preferred IDE does not.
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {
// ...
generates: {
'path/to/file.ts': {
plugins: ['typescript', 'typescript-operations', 'typescript-vue-apollo-smart-ops'],
config: {
addDocBlocks: true
},
},
},
};
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 = {

'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;

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: {

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

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

, spongeCase
, titleCase
, upperCase
, localeUpperCase
and upperCaseFirst

}
},
},
},
};

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

const config: CodegenConfig = {
// ...
generates: {
'path/to/file': {

export default config;
useTypeImports
type: boolean
default: false

compatibility with TypeScript’s “importsNotUsedAsValues”: “error” option
Usage Examples
import type { CodegenConfig } from '@graphql-codegen/cli';
const config: CodegenConfig = {

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.
Examples
Queries
Using the generated query code.
Basic query
For the given input:
query Messages($type: FeedType!) {
feed(type: $type) {
id
}
}
We can use the generated code like this:
<template>
<div>
<div v-if="loading > 0">Loading…</div>
<ul v-else>
<li v-for="message in messages">{{ message.id }}</li>
</ul>
</div>
</template>
<script lang="ts">
import { useMessagesQuery } from '../generated/graphqlOperations'
export default {
apollo: {
messages: useMessagesQuery({
// variables will be correctly typed here!
variables: {
type: 'HOT'
},
loadingKey: 'loading',
update: data => data.feed
})
},
data() {
return {
messages: null,
loading: 0
}
}
}
</script>
Basic mutation
For the given operation:
mutation CreateMessage($text: String!) {
createMessage(text: $text) {
id
}
}
We can use the generated code like this:
<template>
<div>
<textarea v-model="text"></textarea>
<button @click="send">Send Message</button>
</div>
</template>
<script lang="ts">
import { createMessageMutation } from '../generated/graphqlOperations'
export default {
data() {
return {
text: ''
}
},
async send() {
const result = await createMessageMutation(this, {
variables: {
text: this.text
}
})
if (!result.success || !result.data) {
alert('Failed to create message')
return
}
const messageId = result.data.createMessage.id
}
}
</script>
