Construct Props

Name	Type	Description
parent	`IResource`	The parent resource of this resource.
pathPart	`string`	A path name for the resource.
defaultCorsPreflightOptions?	`CorsOptions`	Adds a CORS preflight OPTIONS method to this resource and all child resources.
defaultIntegration?	`Integration`	An integration to use as a default for all methods created within this API unless an integration is specified.
defaultMethodOptions?	`MethodOptions`	Method options to use as a default for all methods created within this API unless custom options are specified.

parent

Type: IResource

The parent resource of this resource.

You can either pass another Resource object or a RestApi object here.

pathPart

Type: string

A path name for the resource.

defaultCorsPreflightOptions?

Type: CorsOptions (optional, default: CORS is disabled)

Adds a CORS preflight OPTIONS method to this resource and all child resources.

You can add CORS at the resource-level using addCorsPreflight.

defaultIntegration?

Type: Integration (optional, default: Inherited from parent.)

An integration to use as a default for all methods created within this API unless an integration is specified.

defaultMethodOptions?

Type: MethodOptions (optional, default: Inherited from parent.)

Method options to use as a default for all methods created within this API unless custom options are specified.

Properties

Name	Type	Description
api	`IRestApi`	The rest API that this resource is part of.
env	`ResourceEnvironment`	The environment this resource belongs to.
node	`Node`	The tree node.
path	`string`	The full path of this resource.
resourceId	`string`	The ID of the resource.
stack	`Stack`	The stack in which this resource is defined.
defaultCorsPreflightOptions?	`CorsOptions`	Default options for CORS preflight OPTIONS method.
defaultIntegration?	`Integration`	An integration to use as a default for all methods created within this API unless an integration is specified.
defaultMethodOptions?	`MethodOptions`	Method options to use as a default for all methods created within this API unless custom options are specified.
parentResource?	`IResource`	The parent of this resource or undefined for the root resource.

api

Type: IRestApi

The rest API that this resource is part of.

The reason we need the RestApi object itself and not just the ID is because the model is being tracked by the top-level RestApi object for the purpose of calculating it's hash to determine the ID of the deployment. This allows us to automatically update the deployment when the model of the REST API changes.

env

Type: ResourceEnvironment

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

node

Type: Node

The tree node.

path

Type: string

The full path of this resource.

resourceId

Type: string

The ID of the resource.

stack

Type: Stack

The stack in which this resource is defined.

defaultCorsPreflightOptions?

Type: CorsOptions (optional)

Default options for CORS preflight OPTIONS method.

defaultIntegration?

Type: Integration (optional)

An integration to use as a default for all methods created within this API unless an integration is specified.

defaultMethodOptions?

Type: MethodOptions (optional)

Method options to use as a default for all methods created within this API unless custom options are specified.

parentResource?

Type: IResource (optional)

The parent of this resource or undefined for the root resource.

Methods

Name	Description
addCorsPreflight(options)	Adds an OPTIONS method to this resource which responds to Cross-Origin Resource Sharing (CORS) preflight requests.
addMethod(httpMethod, integration?, options?)	Defines a new method for this resource.
addProxy(options?)	Adds a greedy proxy resource ("{proxy+}") and an ANY method to this route.
addResource(pathPart, options?)	Defines a new child resource where this resource is the parent.
applyRemovalPolicy(policy)	Apply the given removal policy to this resource.
getResource(pathPart)	Retrieves a child resource by path part.
resourceForPath(path)	Gets or create all resources leading up to the specified path.
toString()	Returns a string representation of this construct.
static fromResourceAttributes(scope, id, attrs)	Import an existing resource.

addCorsPreflight(options)

public addCorsPreflight(options: CorsOptions): Method

Parameters

options CorsOptions

Returns

Method

Adds an OPTIONS method to this resource which responds to Cross-Origin Resource Sharing (CORS) preflight requests.

Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell browsers to give a web application running at one origin, access to selected resources from a different origin. A web application executes a cross-origin HTTP request when it requests a resource that has a different origin (domain, protocol, or port) from its own.

addMethod(httpMethod, integration?, options?)

public addMethod(httpMethod: string, integration?: Integration, options?: MethodOptions): Method

Parameters

httpMethod string
integration Integration
options MethodOptions

Returns

Method

Defines a new method for this resource.

addProxy(options?)

public addProxy(options?: ProxyResourceOptions): ProxyResource

Parameters

options ProxyResourceOptions

Returns

ProxyResource

Adds a greedy proxy resource ("{proxy+}") and an ANY method to this route.

addResource(pathPart, options?)

public addResource(pathPart: string, options?: ResourceOptions): Resource

Parameters

pathPart string
options ResourceOptions

Returns

Resource

Defines a new child resource where this resource is the parent.

applyRemovalPolicy(policy)

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

policy RemovalPolicy

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

getResource(pathPart)

public getResource(pathPart: string): IResource

Parameters

pathPart string

Returns

IResource

Retrieves a child resource by path part.

resourceForPath(path)

public resourceForPath(path: string): Resource

Parameters

path string

Returns

Resource

Gets or create all resources leading up to the specified path.

Path may only start with "/" if this method is called on the root resource.
All resources are created using default options.

toString()

public toString(): string

Returns

string

Returns a string representation of this construct.

static fromResourceAttributes(scope, id, attrs)

public static fromResourceAttributes(scope: Construct, id: string, attrs: ResourceAttributes): IResource

Parameters

scope Construct
id string
attrs ResourceAttributes

Returns

IResource

Import an existing resource.
