SAP HANA XS Advanced, Connecting to SAP Web IDE and cloning a Git Repository to begin development

Connect to Web IDE and Clone a Git Repository to create a Multi-Target Application

Details

SAP HANA Extended Application Services, advanced model is the new development paradigm from SAP based around the Cloud Foundry concepts and architectures.
To begin with you will need see how to connect to the SAP Web IDE for SAP HANA and clone a Git Repository.

As of SPS12, all design-time artifacts are stored in Git instead of the HANA database. We need to setup the repository so development can be collaborative.

Check this series of blogs posts to get introduced to the basic concepts in XS Advanced development, such as Multi-target Applications and micro-services.


Step 1: Launch SAP Web IDE for SAP HANA

These tutorials are based on SAP HANA, express edition. You can get your instance for free following these instructions

By default, in SAP HANA, express edition, SAP Web IDE for SAP HANA can be accessed using https://hxehost:53075/. If you are using a different system, you can check the URL using command xs apps | grep webide in the XS Command Line Interface.

User: XSA_DEV
Password: The password provided when you set up HANA Express

Step 2: Sign in to your Git account

From a separate tab in the web browser, log into GitHub. If you do not have an account, proceed to create one by following the instructions to create and activate your account in the sign up button.

Sign in or sign up to your GitHub account

If you are setting up the repository for use beyond this tutorial, you may want to create an organization and invite other users to join your repository. Further information can be found on GitHub

Alternatively, if you do not wish to create an account on GitHub, you can create a project by right-clicking on your workspace and following the wizard for Multi-Target Applications in New->Project from Template

Step 3: Create a GitHub repository

Whether you have just activated a newly-created account or have been using GitHub disconnected from a HANA workspace, you may wish to create a new repository for this tutorial. If you already have a GitHub repository you would like to use, continue to Step 3.

Follow the instructions in the New Repository option from the + menu in the upper right corner on GitHub.com

New Repository

Complete the form adding a name and description, make sure to tick Initialize this repository with a README and click on Create Repository.

Step 4: Clone the Repository into the Workspace

Form the GitHub page, copy the URL of the repository from the Clone or Download menu

Use the Clone or Download button from the right corner

Return to the SAP Web IDE for SAP HANA. Right click on the Workspace and choose Clone Repository from the Git menu.
Clone Repository in Web IDE

SAP Web IDE for SAP HANA will request the Git URL to access the repository, which you have copied from GitHub:
Repository Cloning parameters

Enter authentication details:
- User: <Your GitHub User ID>
- Password: <You've guessed: Your GitHub password!>

Tick the Remember me box so it will not ask again for the remainder of the session.

If successful, you will see the repository folder in your workspace, which is now connected to the git repository.

Step 5: Configure the Space for the repository

Last, you need to configure the space for the repository you have just linked.

Introduced in SPS12, spaces enable applications to access shared resources that can be used to develop, deploy, and maintain applications.

Right-click on the folder for the repository and select Project Settings

Project Settings for Git repository

Select the proper space (for HANA express, development) from the list of available spaces, or use the space setup by the System Administrator:

Select development space

If you cannot find an appropriate space, you may either lack the SpaceDeveloper role to one or may need to create one. By default, SAP HANA, express edition brings a development space that is implicitly mapped to the system database. If you are planning on using any of the advanced analytics features (such as Machine Learning), you need to map the space to a tenant database, such as the default one, HXE.

Click Save.

Open the GitHub pane using the menu bar on the right to complete the validation for this tutorial
