API Reference

Constructs

SourceApiAssociationMergeOperation

The SourceApiAssociationMergeOperation triggers a merge of a source API during a Cloudformation stack update.

This can be used to propagate changes from the source API to the Merged API when the association is using type MANUAL_MERGE. If the merge operation fails, it will fail the Cloudformation update and rollback the stack.

Initializers 

import { SourceApiAssociationMergeOperation } from 'awscdk-appsync-utils'

new SourceApiAssociationMergeOperation(scope: Construct, id: string, props: SourceApiAssociationMergeOperationProps)
Name Type Description
scope constructs.Construct No description.
id string No description.
props SourceApiAssociationMergeOperationProps No description.
scopeRequired
  • Type: constructs.Construct
idRequired
  • Type: string
propsRequired

Methods

Name Description
toString Returns a string representation of this construct.
toString 
public toString(): string

Returns a string representation of this construct.

Static Functions

Name Description
isConstruct Checks if x is a construct.
isConstruct 
import { SourceApiAssociationMergeOperation } from 'awscdk-appsync-utils'

SourceApiAssociationMergeOperation.isConstruct(x: any)

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.

ID

ID scalar type is a unique identifier. ID type is serialized similar to String.

Often used as a key for a cache and not intended to be human-readable.

STRING

String scalar type is a free-form human-readable text.

INT

Int scalar type is a signed non-fractional numerical value.

FLOAT

Float scalar type is a signed double-precision fractional value.

BOOLEAN

Boolean scalar type is a boolean value: true or false.

AWS_DATE

AWSDate scalar type represents a valid extended ISO 8601 Date string.

In other words, accepts date strings in the form of YYYY-MM-DD. It accepts time zone offsets.

AWS_TIME

AWSTime scalar type represents a valid extended ISO 8601 Time string.

In other words, accepts date strings in the form of hh:mm:ss.sss. It accepts time zone offsets.

AWS_DATE_TIME

AWSDateTime scalar type represents a valid extended ISO 8601 DateTime string.

In other words, accepts date strings in the form of YYYY-MM-DDThh:mm:ss.sssZ. It accepts time zone offsets.

AWS_TIMESTAMP

AWSTimestamp scalar type represents the number of seconds since 1970-01-01T00:00Z.

Timestamps are serialized and deserialized as numbers.

AWS_EMAIL

AWSEmail scalar type represents an email address string (i.e.username@example.com).

AWS_JSON

AWSJson scalar type represents a JSON string.

AWS_URL

AWSURL scalar type represetns a valid URL string.

URLs wihtout schemes or contain double slashes are considered invalid.

AWS_PHONE

AWSPhone scalar type represents a valid phone number. Phone numbers maybe be whitespace delimited or hyphenated.

The number can specify a country code at the beginning, but is not required for US phone numbers.

AWS_IP_ADDRESS

AWSIPAddress scalar type respresents a valid IPv4 of IPv6 address string.

INTERMEDIATE

Type used for Intermediate Types (i.e. an interface or an object type).
