This project is part of the 'IBM Cloud Native Reference Architecture' suite, available at https://github.com/ibm-cloud-architecture/refarch-cloudnative
This project sits between the API gateway and the backend inventory microservices. It is built with Node.js Express and request framework with following functionality:
- Route requests to backend Inventory microservice over Netflix Zuul.
- Serve the application images
- Augment the JSON data payload for Mobile and Web client
The Node.js application is managed under the inventory
folder.
This application depends on Netflix Zuul service to be operational and routing to the backend Inventory microservice.
Routes to microservice URIs are defined in routes/itemservices.js
. Run following command to set microservice base URL to Zuul proxy URL.
# cd inventory
# /bin/bash set-zuul-proxy-url.sh [-m <microservice-app-name> -c <context-path>] -z <zuul-cluster-url>
defaults: -m inventory-microservice -c micro
-
Run the application:
# npm install # npm start
This will start the application on port 3001.
- Validate the local application
http://localhost:3001/api/items/validate
To test the actual endpoint with backend services http://localhost:3001/api/items
- List all items in inventory. Send
GET
request to/api/items
- List item by id. Send

- List all items containing name. Send
GET
request to/api/items//name/{name}
- List all items with price less than or equal to. Send
GET
request to/api/items/price/{price}
- Add item. Send json paylond with
POST
request to/api/items
- Update item by id. Send json payload with

-
Create Auto-Scaling service.
manifest.yml
has Auto-Scaling service name set tocloudnative-autoscale
. If you have an existing Auto-Scaling service with a different name, then edit manifest.yml to update the service name.To create a new Auto-Scaling service with name used in manifest.yml, use the following command.
# cf create-service Auto-Scaling free cloudnative-autoscale
-
Set Cloud Foundry application name.
manifest.yml
has the application and host names set toinventory-bff-app
. You can leave the name as-is or change it. Now, deploy the application.# cf push
-
Validate the Cloud Foundry application. http://inventory-bff-app.mybluemix.net/api/items/validate
This completes deployment of the application to Bluemix Cloud Foundry runtime.
