# @loopback/example-soap-calculator Integrating a Calculator SOAP web service with LoopBack 4. ## Overview 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. ![soap-calculator-overview](https://loopback.io/pages/en/lb4/imgs/loopback-example-soap-calculator_figure1.png) ## Setup You'll need to make sure you have some things installed: - [Node.js](https://nodejs.org/en/) at v10 or greater Lastly, you'll need to install the LoopBack 4 CLI toolkit: ```sh npm i -g @loopback/cli ``` ## Start the Tutorial Follow the following steps to start building your application: ### Steps 1. [SOAP web service overview](https://loopback.io/doc/en/lb4/soap-calculator-tutorial-web-service-overview.html) 2. [Scaffold the application](https://loopback.io/doc/en/lb4/soap-calculator-tutorial-scaffolding.html) 3. [Add a data source](https://loopback.io/doc/en/lb4/soap-calculator-tutorial-add-datasource.html) 4. [Add a service proxy](https://loopback.io/doc/en/lb4/soap-calculator-tutorial-add-service.html) 5.
