AWS AppSync Construct Library

This module is part of the AWS Cloud Development Kit project.

import appsync "github.com/aws/aws-cdk-go/awscdk"

There are no official hand-written (L2) constructs for this service yet. Here are some suggestions on how to proceed:

An experimental construct library for this service is available in preview. Since it is not stable yet, it is distributed as a separate package so that you can pin its version independently of the rest of the CDK. See the package:

@aws-cdk/aws-appsync-alpha

There are no hand-written (L2) constructs for this service yet. However, you can still use the automatically generated L1 constructs, and use this service exactly as you would using CloudFormation directly.

For more information on the resources and properties available for this service, see the CloudFormation documentation for AWS::AppSync.

(Read the CDK Contributing Guide and submit an RFC if you are interested in contributing to this construct library.)

Functions

func CfnApiCache_CFN_RESOURCE_TYPE_NAME 

func CfnApiCache_CFN_RESOURCE_TYPE_NAME() *string

func CfnApiCache_IsCfnElement 

func CfnApiCache_IsCfnElement(x interface{}) *bool

Returns `true` if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of `instanceof` to allow stack elements from different versions of this library to be included in the same stack.

Returns: The construct as a stack element or undefined if it is not a stack element.

func CfnApiCache_IsCfnResource 

func CfnApiCache_IsCfnResource(construct constructs.IConstruct) *bool

Check whether the given construct is a CfnResource.

func CfnApiCache_IsConstruct 

func CfnApiCache_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Use this method instead of `instanceof` to properly detect `Construct` instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the `constructs` library on disk are seen as independent, completely different libraries. As a consequence, the class `Construct` in each copy of the `constructs` library is seen as a different class, and an instance of one class will not test as `instanceof` the other class. `npm install` will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the `constructs` library can be accidentally installed, and `instanceof` will behave unpredictably. It is safest to avoid using `instanceof`, and using this type-testing method instead.

Returns: true if `x` is an object created from a class which extends `Construct`.

A CloudFormation `AWS::AppSync::FunctionConfiguration`.

The `AWS::AppSync::FunctionConfiguration` resource defines the functions in GraphQL APIs to perform certain operations. You can use pipeline resolvers to attach functions. For more information, see [Pipeline Resolvers](https://docs.aws.amazon.com/appsync/latest/devguide/pipeline-resolvers.html) in the *AWS AppSync Developer Guide* .

> When you submit an update, AWS CloudFormation updates resources based on differences between what you submit and the stack's current template. To cause this resource to be updated you must change a property value for this resource in the AWS CloudFormation template. Changing the Amazon S3 file content without changing a property value will not result in an update operation. > > See [Update Behaviors of Stack Resources](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html) in the *AWS CloudFormation User Guide* .

A CloudFormation `AWS::AppSync::GraphQLSchema`.

The `AWS::AppSync::GraphQLSchema` resource is used for your AWS AppSync GraphQL schema that controls the data model for your API. Schema files are text written in Schema Definition Language (SDL) format. For more information about schema authoring, see [Designing a GraphQL API](https://docs.aws.amazon.com/appsync/latest/devguide/designing-a-graphql-api.html) in the *AWS AppSync Developer Guide* .

> When you submit an update, AWS CloudFormation updates resources based on differences between what you submit and the stack's current template. To cause this resource to be updated you must change a property value for this resource in the CloudFormation template. Changing the Amazon S3 file content without changing a property value will not result in an update operation. > > See [Update Behaviors of Stack Resources](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html) in the *AWS CloudFormation User Guide* .
