Implements IConstruct, IDependable, IResource, IRestApi

Defines an API Gateway REST API with AWS Lambda proxy integration.

Use the proxy property to define a greedy proxy ("{proxy+}") and "ANY" method from the specified path. If not defined, you will need to explicity add resources and methods to the API.

Example

declare const sourceQueue: sqs.Queue;

const fn = new lambda.Function( this, 'MyFunc', {
  handler: 'index.handler',
  runtime: lambda.Runtime.NODEJS_LATEST,
  code: lambda.Code.fromInline( 'exports.handler = e => {}' ),
});

const restApi = new api.LambdaRestApi( this, 'MyRestAPI', { handler: fn } );
const apiTarget = new targets.ApiGatewayTarget(restApi);

const pipe = new pipes.Pipe(this, 'Pipe', {
    source: new SqsSource(sourceQueue),
    target: apiTarget,
});

Initializer

new LambdaRestApi(scope: Construct, id: string, props: LambdaRestApiProps)

• scope Construct
• id string

handler

Type: IFunction

The default Lambda function that handles all requests from this API.

This handler will be used as a the default integration for all methods in this API, unless specified otherwise in addMethod.

---

apiKeySourceType?

Type: ApiKeySourceType (optional, default: Metering is disabled.)

The source of the API key for metering requests according to a usage plan.

---

binaryMediaTypes?

Type: string[] (optional, default: RestApi supports only UTF-8-encoded text payloads.)

The list of binary media mime-types that are supported by the RestApi resource, such as "image/png" or "application/octet-stream".

---

cloneFrom?

Type: IRestApi (optional, default: None.)

The ID of the API Gateway RestApi resource that you want to clone.

---

cloudWatchRole?

Automatically configure an AWS CloudWatch role for API Gateway.

---

cloudWatchRoleRemovalPolicy?

Type: RemovalPolicy (optional, default: RemovalPolicy.RETAIN)

The removal policy applied to the AWS CloudWatch role when this resource is removed from the application.

Requires cloudWatchRole to be enabled.

---

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.)

---

deploy?

Type: boolean (optional, default: true)

Indicates if a Deployment should be automatically created for this API, and recreated when the API model (resources, methods) changes.

Since API Gateway deployments are immutable, When this option is enabled (by default), an AWS::ApiGateway::Deployment resource will automatically created with a logical ID that hashes the API model (methods, resources and options). This means that when the model changes, the logical ID of this CloudFormation resource will change, and a new deployment will be created.

If this is set, latestDeployment will refer to the Deployment object and deploymentStage will refer to a Stage that points to this deployment. To customize the stage options, use the deployOptions property.

A CloudFormation Output will also be defined with the root URL endpoint of this REST API.

---

deployOptions?

Type: StageOptions (optional, default: Based on defaults of StageOptions.)

Options for the API Gateway stage that will always point to the latest deployment when deploy is enabled.

If deploy is disabled, this value cannot be set.

A description of the RestApi construct.

---

disableExecuteApiEndpoint?

Type: boolean (optional, default: false)

Specifies whether clients can invoke the API using the default execute-api endpoint.

To require that clients use a custom domain name to invoke the API, disable the default endpoint.

See also: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-restapi.html

---

domainName?

Type: DomainNameOptions (optional, default: no domain name is defined, use addDomainName or directly define a DomainName.)

Configure a custom domain name and map it to this API.

---

---

integrationOptions?

Type: LambdaIntegrationOptions (optional, default: see defaults defined in LambdaIntegrationOptions.)

Specific Lambda integration options.

---

minCompressionSize?

Type: Size (optional, default: Compression is disabled.)

A Size(in bytes, kibibytes, mebibytes etc) that is used to enable compression (with non-negative between 0 and 10485760 (10M) bytes, inclusive) or disable compression (when undefined) on an API.

When compression is enabled, compression or decompression is not applied on the payload if the payload size is smaller than this value. Setting it to zero allows compression for any payload size.

---

minimumCompressionSize?⚠️

⚠️ Deprecated: - superseded by minCompressionSize

Type: number (optional, default: Compression is disabled.)

A nullable integer that is used to enable compression (with non-negative between 0 and 10485760 (10M) bytes, inclusive) or disable compression (when undefined) on an API.

When compression is enabled, compression or decompression is not applied on the payload if the payload size is smaller than this value. Setting it to zero allows compression for any payload size.

---

Type: { [string]: string } (optional, default: No parameters.)

Custom header parameters for the request.

See also: https://docs.aws.amazon.com/cli/latest/reference/apigateway/import-rest-api.html

---

policy?

Type: PolicyDocument (optional, default: No policy.)

A policy document that contains the permissions for this RestApi.

---

proxy?

Type: boolean (optional, default: true)

If true, route all requests to the Lambda Function.
