This is a stable example. It should successfully build out of the box

This example is built on Construct Libraries marked "Stable" and does not have any infrastructure prerequisites to build.

This an example of an APIGateway with Express Step Functions integrated. The Step Functions invokes two Lambda functions in parallel. The outcomes from these two Lambda functions are aggregated and returned as the response through APIGateway.

{
    "normal":"{\"message\":\"Hello World!\"}",
    "fast":"{\"message\":\"Hello World zzZ! (Sleepy)\"}"
}

Property normal is the outcome from Lambda-1 and fast is the outcome from Lambda-2.

To build this app, you need to be in this example's root folder. Then run the following:

npm install -g aws-cdk
npm install

This will install the necessary CDK, then this example's dependencies.

Run cdk deploy. This will deploy / redeploy your Stack to your AWS Account.

After the deployment you will see the API's URL, which represents the url you can then use.

The cdk.json file in the root of this repository includes instructions for the CDK toolkit on how to execute this program.

After building your TypeScript code, you will be able to run the CDK toolkit commands as usual:

    $ cdk ls
    <list all stacks in this program>

    $ cdk synth
    <generates and outputs cloudformation template>

    $ cdk deploy
    <deploys stack to your account>

    $ cdk diff
    <shows diff against deployed stack>
