# IEventBus

Interface which all EventBus based classes MUST implement.

Extends: IEventBus
Extends: IResource, IEventBusRef
Implemented by: EventBus

- Source: [`aws-events/lib/event-bus.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0/packages/aws-cdk-lib/aws-events/lib/event-bus.ts#L76)
- Type last changed: v2.227.0 · 21 Nov 2025

## Properties

- `env`: [ResourceEnvironment](/cdk/api/v2/docs/aws-cdk-lib.interfaces.ResourceEnvironment.html) — The environment this resource belongs to.

  For resources that are created and managed in a Stack (those created by
  creating new class instances like `new Role()`, `new Bucket()`, etc.), this
  is always the same as the environment of the stack they belong to.

  For referenced resources (those obtained from referencing methods like
  `Role.fromRoleArn()`, `Bucket.fromBucketName()`, etc.), they might be
  different than the stack they were imported into.

- `eventBusArn`: string — The ARN of this event bus resource.

- `eventBusName`: string — The physical ID of this event bus resource.

- `eventBusPolicy`: string — The JSON policy of this event bus resource.

- `eventBusRef`: [EventBusReference](/cdk/api/v2/docs/aws-cdk-lib.interfaces.aws_events.EventBusReference.html) — A reference to a EventBus resource.

- `eventSourceName`: string — The partner event source to associate with this event bus resource.

- `node`: [Node](/cdk/api/v2/docs/constructs.Node.html) — The tree node.

- `stack`: [Stack](/cdk/api/v2/docs/aws-cdk-lib.Stack.html) — The stack in which this resource is defined.

## Methods

- `applyRemovalPolicy(policy: RemovalPolicy): void` — 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`).

- `archive(id: string, props: BaseArchiveProps): Archive` — Create an EventBridge archive to send events to.

  When you create an archive, incoming events might not immediately start being sent to the archive.
  Allow a short period of time for changes to take effect.

  **Parameters**

  - `props` — Properties of the archive.

- `grantPutEventsTo(grantee: IGrantable, sid?: string): Grant` — Grants an IAM Principal to send custom events to the eventBus so that they can be matched to rules.

  **Parameters**

  - `grantee` — The principal (no-op if undefined).
  - `sid` — The Statement ID used if we need to add a trust policy on the event bus.

- `with(...mixins: IMixin[]): IConstruct` — Applies one or more mixins to this construct.

  Mixins are applied in order. The list of constructs is captured at the
  start of the call, so constructs added by a mixin will not be visited.

  **Parameters**

  - `mixins` — The mixins to apply.

  **Returns:** This construct for chaining
