Service Invocation

In this quickstart, you'll create a checkout service and an order processor service to demonstrate how to use the service invocation API. The checkout service uses Dapr's http proxying capability to invoke a method on the order processing service.

Visit this link for more information about Dapr and service invocation.

This quickstart includes one checkout service:

  • Node client service checkout

And one order-processor service:

  • Node order-processor service order-processor

Run Node order-processor with Dapr

  1. Open a new terminal window and navigate to order-processor directory and install dependencies:
cd service_invocation/javascript/http/order-processor
npm install
  1. Run the Node order-processor app with Dapr:
cd service_invocation/javascript/http/order-processor
dapr run --app-port 5001 --app-id order-processor --app-protocol http --dapr-http-port 3501 -- npm start

Run Node checkout with Dapr

  1. Open a new terminal window and navigate to checkout directory and install dependencies:
cd service_invocation/javascript/http/checkout
npm install
  1. Run the Node checkout app with Dapr:
cd service_invocation/javascript/http/checkout
dapr run  --app-id checkout --app-protocol http --dapr-http-port 3500 -- npm start
