XS Advanced, Create a CAP model project

07/29/2019

Use the wizard for the Cloud Application Programming model to create a project in SAP HANA, express edition.

You will learn

  • How to create an application with the wizard for the Cloud Application Programming model
  • How to use the local Git repository for development/testing purposes

The images in this tutorial are based on SAP HANA, express edition SPS04. SAP Web IDE Full-Stack may have some minor differences.


Step 1: Create a new project

Log into SAP Web IDE.

The default URL for SAP Web IDE in SAP HANA, express edition is https://hxehost:53075. The default user is XSA_DEV

Right-click on Workspace and select New-> Project from Template

New CAP model project

Choose SAP Cloud Platform Business Application and click Next.

New CAP model project

Use the following name for your project and click Next

MyHANAApp

This name will be used in different steps. It is recommended that you do not change it unless you remember to replace it in future tasks.

Step 2: Explore the generated artifacts

The wizard has generated a Multi-target Application with two modules: a database module and a service module. Expand them to familiarize yourself with the basic folder structure.

New CAP model project

The wizard has also populated the mta.yaml configuration file with the necessary dependencies and parameters for each module. Open it in the code editor to explore it.

This file is the deployment descriptor and it is the glue that keeps all the micro-services together as a single application throughout its lifecycle. It declares the modules (applications or micro-services) and their dependencies with other micro-services or backing services. You can also use this file to inject variables into the environment variable VCAP_SERVICES of your application.

This file is very sensitive to indentation and does not allow for tabs.

Step 3: Initialize local Git repository

You will use the local Git repository for basic version management.

Right-click on the project and choose Git -> Initialize Local Repository.

Initialize Git

You will be asked for an email address and user ID for a remote GitHub server. You can enter bogus values if you do not have an account in a remote GitHub repository.

Initialize Git

After a few seconds, you will see a success message in the top-right corner. Use the Git icon next to it to open the Git pane.

Step 4: Perform your first commit

Each time you commit to the local or remote repository, you create a version. This will allow you to revert and compare any changes.
It is recommended that you perform commits at the end of each tutorial.

Add a commit message and click Commit:

Initialize Git

It is recommended to set a remote repository in, for example, GitHub. This will allow you to have a copy of your code outside your SAP HANA instance.

Click the console icon and look at the messages to complete the validation below.
