Amazon web services – Creating Lambda Snapstart with Typescript CDK

Here is the TypeScript sample:

import * as lambda from "@aws-cdk/aws-lambda";
import * as cdk from "@aws-cdk/core";

export class LambdaSnapStartStack extends cdk.Stack {
    constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
        super(scope, id, props);

        const lambdaFunction = new lambda.Function(this, "lambda-function", {
            functionName: "MyPrettyFunction",
            runtime: lambda.Runtime.PYTHON_3_9,
            memorySize: 1024,
            timeout: cdk.Duration.seconds(30),
            handler: "my_lambda.lambda_handler",
            code: lambda.Code.fromAsset("my_lambda.zip")
            // other properties
        });

        // Enable SnapStart
        const cfnFunction = lambdaFunction.node.defaultChild as lambda.CfnFunction;
        cfnFunction.addPropertyOverride("SnapStart", { ApplyOn: "PublishedVersions" });
    }
}
