Run the Application Locally

Introduction

Before you deploy the application on SAP BTP, you can run the CAP application locally to test and ensure that your code changes are working.

Procedure

  1. To open a new terminal in your development environment, choose Terminal → New Terminal.

  2. To start the CAP server, run the cds watch command.

  3. Make sure you have installed the extension REST Client. Go to Extensions and search for REST Client. If this extension is not installed yet, choose Install.

  4. Navigate back to the root folder of your application and create a new file called request.http.

  5. Copy the following code snippet to the request.http file:

PATCH  http://localhost:4004/odata/v4/api-business-partner/A_BusinessPartner('1004100') HTTP/1.1
Content-Type: application/json
Authorization: Basic YWxpY2U6

{
     "to_BusinessPartnerAddress": [{
        "AddressID": "456",
        "to_EmailAddress":[{
            "AddressID": "456",
            "Person": "johnson",
            "OrdinalNumber": "334",
            "EmailAddress": "sunny@test.com"
        }]
    }]
}

Hint: The file is auto saved in SAP Business Application Studio.

  1. Choose Send Request at the top of the file. Check if you see the following message in the terminal:

    Send request

>> BusinessPartner.Changed
<< received BusinessPartner.Changed { BusinessPartner: '1004100' }

If API_BUSINESS_PARTNER doesn't show up, remove the .cds-services.json file. You can find it in the user's root folder (for example, /home/user/.cds-services.json)
