Welcome to SAP Cloud Application Programming model samples

Find here the samples for the openSAP course Building Applications with the SAP Cloud Application Programming Model.

Get Access to SAP Business Application Studio

The recommended environment for the course is SAP Business Application Studio. Watch unit 2 of week 1 for how to get access.

Setup

In SAP Business Application Studio, open a terminal. Then clone the repo with this specific branch:

git clone https://github.com/sap-samples/cloud-cap-samples projects/cloud-cap-samples -b openSAP-week3-unit5
cd projects/cloud-cap-samples

In the cloud-cap-samples folder run:

npm install

Run

Now you're ready to run the samples, for example:

cd packages/bookshop
cds deploy
cds watch

After that, watch out for the little popup in the lower right corner of SAP Business Application Studio that asks you to open the application in your browser.

Hints

If your demo user logon window does not show up: clear the browsers login data
If your port is still in use run in your terminal:

> pkill node      //kill running node proceses

Deploy to Cloud Foundry

Clean-up the CF space in your trial account if you already used it before. Make sure that there are no services or applications deployed.

Generation of the XSUAA service configuration file xs-security.json:

cds compile srv/ --to xsuaa > xs-security.json

In this unit we use MTA to do the deployment to CF

npm install -g mbt

You can generate the MTA.yaml from CDS and do manual modifications or simply use the already generated and adapted mta.yaml in the branch and directly generate the .mtar file

BEGIN OPTIONAL PART

If you want to generate the MTA.YAML yourself please do the following:

Generate the mta.yaml with the HANA dependency

cds add hana --force
cds add mta

Add the path to the generated xs-security.json in the MTA.YAML

    parameters:
         path: ./xs-security.json
         service:xsuaa
         service-plan: application
         ....

Add the application block in the MTA.YAML

     ##############    APP   #########################
     - name: capire-bookshop-app
       type: nodejs
       path: gen/app
       parameters:
          memory: 256M
       build-parameters:
         requires:
           - name: capire-bookshop-srv
       requires:
        - name: capire-bookshop-uaa
        - name: srv-binding
          group: destinations
          properties:
             forwardAuthToken: true
             name: srv-binding
             url: ~{srv-url}

Make sure to use service hanatrial instead of hana in the MTA.YAML

   parameters:
     service: hanatrial

END OPTIONAL PART

Generate the .mtar file for the deployment and deploy to cloud foundry:

mbt build -t ./
cf login -a https://api.cf.eu10.hana.ondemand.com
cf deploy sap.capire-bookshop_1.0.0.mtar
