How to connect Node.js application to public and On-Premise system – Cloud Foundry environment
Github repository:
To be published soon…
Introduction:
- In this session, we will look at how to connect Node.js application to public and On-Premise systems in SAP Cloud Platform – Cloud Foundry environment
Synopsis:
- In the previous sessions, we had looked at how to connect SAPUI5 applications to public and On-Premise systems
- The key differentiator between SAPUI5 application and Node.js application is that the Node.js application runs on the backend whereas the SAPUI5 application runs on the browser
- We will make use of axios – a popular npm package for making HTTP requests
- The Connectivity Service and Destination Service together can be used to connect to On-Premise systems
- The Connectivity Service acts as a standard HTTP proxy to connect and retrieve data from the On-Premise system
Steps:
- In this example, we will create a simple Node.js application and consume the publicly available Northwind OData Service
- Then we will modify the Node.js application to consume the publicly available Northwind OData Service – but this time reading key information from the Destination Service
- We will then consume the On-Premise OData Service using both the Destination Service and the Connectivity Service

Conclusion:
- This video should give you a clear idea on how to use the Destination Service and Connectivity Service together in a Node.js application to connect to both publicly available endpoints and On-Premise systems
- If you have questions or comments, please list them below and I will be happy to answer
