$ cd typescript/my-widget-service
$ npm install
$ npm run build
$ cdk deploy  // Deploys the CloudFormation template

# Afterwards
$ cdk destroy

JavaScript examples

Select the following link to see how to install and run the example.

Example	Description
aws-cdk-changelogs-demo	A full serverless Node.js application stack deployed using CDK. It uses AWS Lambda, AWS Fargate, DynamoDB, Elasticache, S3, and CloudFront.

.NET examples

Example	Description
my-widget-service	Use Lambda to serve up widgets
random-writer	This sample application demonstrates some essential mechanisms of the AWS CDK for .NET. It uses AWS Lambda, DynamoDB, CloudWatch.

To run a .NET example, say my-widget-service:

$ npm install -g aws-cdk
$ cd csharp/my-widget-service
$ dotnet build src
