This AWS Solutions Construct implements an Amazon Cognito securing an Amazon API Gateway Lambda backed REST APIs pattern.
Here is a minimal deployable pattern definition:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { CognitoToApiGatewayToLambda } from '@aws-solutions-constructs/aws-cognito-apigateway-lambda';
import * as lambda from 'aws-cdk-lib/aws-lambda';
new CognitoToApiGatewayToLambda(this, 'test-cognito-apigateway-lambda', {
lambdaFunctionProps: {
code: lambda.Code.fromAsset(`lambda`),
runtime: lambda.Runtime.NODEJS_16_X,
handler: 'index.handler'
}
});
Python
from aws_solutions_constructs.aws_cognito_apigateway_lambda import CognitoToApiGatewayToLambda
from aws_cdk import (
aws_lambda as _lambda,
Stack
)
from constructs import Construct
CognitoToApiGatewayToLambda(self, 'test-cognito-apigateway-lambda',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset('lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
)
)
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.cognitoapigatewaylambda.*;
new CognitoToApiGatewayToLambda(this, "test-cognito-apigateway-lambda",
new CognitoToApiGatewayToLambdaProps.Builder()
.lambdaFunctionProps(new FunctionProps.Builder()
.runtime(Runtime.NODEJS_16_X)
.code(Code.fromAsset("lambda"))
.handler("index.handler")
.build())
.build());
If you are defining resources and methods on your API (e.g. proxy = false), then you must call addAuthorizers() after the API is fully defined to ensure every method is protected. Here is an example:
Typescript
import { Construct } from 'constructs';
import { Stack, StackProps } from 'aws-cdk-lib';
import { CognitoToApiGatewayToLambda } from '@aws-solutions-constructs/aws-cognito-apigateway-lambda';
import * as lambda from 'aws-cdk-lib/aws-lambda';
const construct = new CognitoToApiGatewayToLambda(this, 'test-cognito-apigateway-lambda', {
lambdaFunctionProps: {
code: lambda.Code.fromAsset(`lambda`),
runtime: lambda.Runtime.NODEJS_16_X,
handler: 'index.handler'
},
apiGatewayProps: {
proxy: false
}
});
const resource = construct.apiGateway.root.addResource('foobar');
resource.addMethod('POST');
// Mandatory to call this method to Apply the Cognito Authorizers on all API methods
construct.addAuthorizers();
Python
from aws_solutions_constructs.aws_cognito_apigateway_lambda import CognitoToApiGatewayToLambda
from aws_cdk import (
aws_lambda as _lambda,
aws_apigateway as api,
Stack
)
from constructs import Construct

# Overriding LambdaRestApiProps with type Any
gateway_props = dict[Any, Any]
construct = CognitoToApiGatewayToLambda(self, 'test-cognito-apigateway-lambda',
lambda_function_props=_lambda.FunctionProps(
code=_lambda.Code.from_asset(
'lambda'),
runtime=_lambda.Runtime.PYTHON_3_9,
handler='index.handler'
),
api_gateway_props=gateway_props(
proxy=False
)
)
resource = construct.api_gateway.root.add_resource('foobar')
resource.add_method('POST')
# Mandatory to call this method to Apply the Cognito Authorizers on all API methods
construct.add_authorizers()
