Server-side JavaScript files have the file suffix .xsjs, for example, hello.xsjs and contain the code that is
executed when SAP HANA XS handles a URL request.
$.response.contentType = "text/plain";
$.response.setBody( "Hello, World!");
6. Check the layout workspace.
Your application package structure should have a structure that looks like the following example:
.
\
helloxsjs
\.xsapp
.xsaccess
hello.xsjs
7. Save and activate your changes and additions.
8. View the results.
The SAP HANA XS Web server enables you to view the results immediately after activation in the repository,
for example: http://dbhost:80/helloxsjs/hello.xsjs
9.3 Writing JavaScript Libraries
9.3.1 Server-Side JavaScript Libraries
The elements defined in normal server-side JavaScript programs cannot be accessed from other JavaScript
programs. To enable the reuse of program elements, SAP HANA Extended Application Services support serverside
JavaScript libraries.
Server-side JavaScript libraries are a special type of JavaScript program that can be imported and called in other
JavaScript programs. You can use JavaScript libraries to perform simple, repetitive tasks, for example, to handle
forms and form date, to manipulate date and time strings, to parse URLs, and so on.
Note: JavaScript libraries are internally developed extensions for SAP HANA.
The following example shows how to import a JavaScript mathematics library using the import function:
// import math lib
$.import("sap.myapp.lib","math");
// use math lib
var max_res = $.sap.myapp.lib.math.max(3, 7);
The import function requires the following parameters:
● Package name
Full name of the package containing the library object you want to import, for example, sap.myapp.lib
● Library name
Name of the library object you want to import, for example, math
