ServiceConfig

GraphqlServiceConfig

init

Sets a given value for a given key in the GraphQL context.



'key

string

value

Retrieves a value using the given key from the GraphQL context.



The value if the key is present in the context, a `graphql:Error` otherwise

Context

ClientError

Executes a GraphQL document and data binds the GraphQL response to a record with data and extensions 
which is a subtype of GenericResponse.



executeWithType

The GraphQL document. It can include queries & mutations. 
For example `query OperationName($code:ID!) {country(code:$code) {name}}`.


document

The GraphQL variables. For example `{"code": "<variable_value>"}`.


variables

The GraphQL operation name. If a request has two or more operations, then each operation must have a name. 
A request can only execute one operation, so you must also include the operation name to execute.


operationName

The GraphQL API headers to execute each query 


headers

The payload, which is expected to be returned after data binding. For example 
`type CountryByCodeResponse record {| map<json?> extensions?; record {| record{|string name;|}? country; |} data;`


targetType

The GraphQL response or a `graphql:ClientError` if failed to execute the query


Executes a GraphQL document and data binds the GraphQL response to a record with data, extensions and errors 
which is a subtype of GenericResponseWithErrors.



execute

The GraphQL document. It can include queries & mutations. 
For example `query countryByCode($code:ID!) {country(code:$code) {name}}`.


The payload (`GenericResponseWithErrors`), which is expected to be returned after data binding. For example 
`type CountryByCodeResponse record {| map<json?> extensions?; record {| record{|string name;|}? country; |} data; ErrorDetail[] errors?; |};`


Client

The prefix used to denote the Basic authentication scheme.


AUTH_SCHEME_BASIC

The prefix used to denote the Bearer authentication scheme.


AUTH_SCHEME_BEARER

Represents the authentication error type.


Error

AuthnError

ServerError

Represents any error related to the Ballerina GraphQL module.


Represents GraphQL client side or network level errors.


anydata

body

Represents GraphQL API response during GraphQL API server side errors.


json

data

ErrorDetail

errors

extensions

Invoked during the initialization of a `graphql:Listener`. Either an `http:Listner` or a port number must be
provided to initialize the listener.



An `http:Listener` or a port number to listen to the GraphQL service endpoint


listenTo

The additional configurations for the GraphQL listener


configuration

ListenerConfiguration

A `graphql:Error` if the listener initialization is failed or else `()`


Attaches the provided service to the Listener.



attach

The `graphql:Service` object to attach to the listener


Service

name

A `graphql:Error` if an error occurred during the service-attaching process or the schema
generation process or else `()`


Detaches the provided service from the Listener.



detach

The service to be detached from the listener


A `graphql:Error` if an error occurred during the service detaching process or else `()`


'start

A `graphql:Error`, if an error occurred during the service starting process, otherwise nil


Gracefully stops the graphql listener. Already accepted requests will be served before the connection closure.



gracefulStop

A `graphql:Error`, if an error occurred during the service stopping process, otherwise nil


Stops the service listener immediately.



immediateStop

A `graphql:Error` if an error occurred during the service stopping process or else `()`


Listener

exposeHeaders

Specifies whether credentials are required to access the service

allowCredentials

The maximum duration to cache the preflight from client side

maxAge

CorsConfig

Represents the details of an error occurred during parsing, validating, or executing a GraphQL document.


message

The locations in the GraphQL document related to the error

locations

path

Represents file user store configurations for Basic Auth authentication.


FileUserStoreConfig

Represents the auth annotation for file user store configurations with scopes.



File user store configurations for Basic Auth authentication


fileUserStoreConfig

scopes

FileUserStoreConfigWithScopes

Represents the target type binding record with data and extensions of a GraphQL response for `executeWithType` method.



Meta information on protocol extensions from the GraphQL server


The requested data from the GraphQL server


GenericResponse

Represents the target type binding record with data, extensions and errors of a GraphQL response for `execute` method.



The errors occurred (if present) while processing the GraphQL request.


GenericResponseWithErrors

Represent GraphiQL client configurations



enable

boolean

Graphiql

Provides a set of configurations for the GraphQL service.



maxQueryDepth

auth
