Properties

Name	Type	Description
env	ResourceEnvironment	The environment this resource belongs to.
node	ConstructNode	The construct tree node associated with this construct.
oAuthFlows	OAuthFlows	The OAuth flows enabled for this client.
stack	Stack	The stack in which this resource is defined.
userPoolClientId	string	Name of the application client.
userPoolClientName	string	The client name that was specified via the userPoolClientName property during initialization, throws an error otherwise.

---

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: ConstructNode

The construct tree node associated with this construct.

---

oAuthFlows

Type: OAuthFlows

The OAuth flows enabled for this client.

---

stack

Type: Stack

The stack in which this resource is defined.

---

userPoolClientId

Type: string

Name of the application client.

---

userPoolClientName

Type: string

The client name that was specified via the userPoolClientName property during initialization, throws an error otherwise.

Methods

Name	Description
applyRemovalPolicy(policy)	Apply the given removal policy to this resource.
toString()	Returns a string representation of this construct.
static fromUserPoolClientId(scope, id, userPoolClientId)	Import a user pool client given its id.

---

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).

---

toString()

public toString(): string

Returns

• string

Returns a string representation of this construct.

---

static fromUserPoolClientId(scope, id, userPoolClientId)

public static fromUserPoolClientId(scope: Construct, id: string, userPoolClientId: string): IUserPoolClient

Parameters

• scope Construct
• id string
• userPoolClientId string

Returns

• IUserPoolClient

Import a user pool client given its id.
