AWS Lambda Step Functions

This is a demonstration of serverless state machines with AWS Step Functions.

It uses the Serverless framework for easy deployment.

Make sure the plugins are installed (npm install) and then run serverless deploy to deploy the project.

Step Functions

The project defines Step Functions composed of Lambda Functions. The Step Functions are exposed over HTTPS.

The Step Functions can be executed like so (you need to substitute the correct URL)

curl -XPOST https://SOMEPREFIX.execute-api.eu-central-1.amazonaws.com/dev/sales/upload -d  @data/sales_aalborg.json

Lambda Functions

You can use the example data in the data directory to try out the services.

Shops

upload-shops

For example, you can try out the upload-shops function like this:

serverless invoke -f upload-shops -p data/shops.json

The -p option specifies a path to a JSON or YAML file holding input data.

list-shops

Get the list of all shops.

serverless invoke -f list-shops

Sales

upload-sales

You can upload some sales data for the shops like so:

serverless invoke -f upload-sales -p data/sales_aalborg.json
serverless invoke -f upload-sales -p data/sales_hobro.json
serverless invoke -f upload-sales -p data/sales_randers.json

generate-weekly-sales-report

This generates the weekly sales report for one shop for one week. You must specify the date for the report and the shopNumber.

serverless invoke -f generate-weekly-sales-report --data '{"date":"2017-07-12", "shopNumber": 1}'
