Overview
This AWS Solutions Construct implements an Amazon API Gateway REST API connected to an AWS Lambda function pattern.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { ApiGatewayToLambda } from '@aws-solutions-constructs/aws-apigateway-lambda';
import * as lambda from 'aws-cdk-lib/aws-lambda';
new ApiGatewayToLambda(this, 'ApiGatewayToLambdaPattern', {
lambdaFunctionProps: {
runtime: lambda.Runtime.NODEJS_16_X,
handler: 'index.handler',
code: lambda.Code.fromAsset(`lambda`)
}
});
Python
from aws_solutions_constructs.aws_apigateway_lambda import ApiGatewayToLambda
from aws_cdk import (
aws_lambda as _lambda,
Stack
)
from constructs import Construct
ApiGatewayToLambda(self, 'ApiGatewayToLambdaPattern',
lambda_function_props=_lambda.FunctionProps(
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler',
code=_lambda.Code.from_asset('lambda')
)
)
Java
import software.constructs.Construct;
import software.amazon.awscdk.Stack;
import software.amazon.awscdk.StackProps;
import software.amazon.awscdk.services.lambda.*;
import software.amazon.awscdk.services.lambda.Runtime;
import software.amazon.awsconstructs.services.apigatewaylambda.*;
new ApiGatewayToLambda(this, "ApiGatewayToLambdaPattern", new ApiGatewayToLambdaProps.Builder()
.lambdaFunctionProps(new FunctionProps.Builder()
.runtime(Runtime.NODEJS_16_X)
.code(Code.fromAsset("lambda"))
.handler("index.handler")
.build())
.build());
Pattern Construct Props
Name | Type | Description |
---|---|---|
existingLambdaObj? | lambda.Function |
Existing instance of Lambda Function object, providing both this and lambdaFunctionProps will cause an error. |
lambdaFunctionProps? | lambda.FunctionProps |
User provided props to override the default props for the Lambda function. |
apiGatewayProps? | api.LambdaRestApiProps |
Optional user-provided props to override the default props for the API. |
logGroupProps? | logs.LogGroupProps |
User provided props to override the default props for for the CloudWatchLogs LogGroup. |
Pattern Properties
Name | Type | Description |
---|---|---|
lambdaFunction | lambda.Function |
Returns an instance of the Lambda function created by the pattern. |
apiGateway | api.LambdaRestApi |
Returns an instance of the API Gateway REST API created by the pattern. |
apiGatewayCloudWatchRole? | iam.Role |
Returns an instance of the iam.Role created by the construct for API Gateway for CloudWatch access. |
apiGatewayLogGroup | logs.LogGroup |
Returns an instance of the LogGroup created by the construct for API Gateway access logging to CloudWatch. |
Default settings
Out of the box implementation of the Construct without any override will set the following defaults:
Amazon API Gateway
- Deploy an edge-optimized API endpoint
- Enable CloudWatch logging for API Gateway
- Configure least privilege access IAM role for API Gateway
- Set the default authorizationType for all API methods to IAM
- Enable X-Ray Tracing
AWS Lambda Function
-
Configure limited privilege access IAM role for Lambda function
-
Enable reusing connections with Keep-Alive for NodeJs Lambda function
-
Enable X-Ray Tracing
-
Set Environment Variables
- AWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)
