Exercise 01: Creating a new Business Application using local development tools

Estimated time

10 minutes

Objective

In this exercise we will learn to set up our local development environment and create a new node.js project. This will be our codebase to create the Space travel application.

Exercise description

  1. Setup npm registry
npm set @sap:registry=https://npm.sap.com
  1. Install cds command line tool.
npm i -g @sap/cds

Now, the following command should print the version information

cds --version

At the time of writing this exercise the newest version is 3.5.2

  1. With the cds init command a new project is created. Here, let us use cloud-sample-spaceflight-node as the project name. In addition, the option --modules srv,db stating that we want to have service and db modules.The options --mta and --db-technology hana are for the creation of a mta.yml file with description needed once we move to the WebIDE environment.
cds init cloud-sample-spaceflight-node --modules srv,db --mta --db-technology hana

After the successful execution of the command a new directory cloud-sample-spaceflight-node is created together with a project structure and content within.

  1. Goto SAP Development tools page and scroll down to the end to download the CDS extension as shown. Click on the .vsix file and the file download will begin. This may trigger the license agreement popup if you are accessing the page for the first time. Click the I Have Read And Agree button and proceed. In case the downloaded file is a zip archive, extract it.

The project contains db and srv folders which corresponds to the Database and Service modules.

Package.json file contains the list of dependencies of the project. The "node_modules" folder contains dowloaded packages of these dependencies in our local develoment environment.
