Integrating a Calculator SOAP web service with LoopBack 4.
This example project shows how to integrate a SOAP web service with LoopBack 4 and expose its methods through the REST API server. Acceptance and Integration tests are provided.
Before each step, you will be presented an image containing the artifacts that you will be creating in blue.
You’ll need to make sure you have some things installed:
- Node.js at v8.9 or greater
Lastly, you’ll need to install the LoopBack 4 CLI toolkit:
