How does jQuery.sap.require work?
Does SAPUI5 load the libraries each time I call jQuery.sap.require("someLibrary") ? For instance if I am calling the above statement in multiple modules in my application, is "someLibrary" loaded multiple times also? The lib is only loaded once. You can find this information in the SDK https://sapui5.hana.ondemand.com/sdk/#docs/guide/ModularizationConcept.html Module Loading As mentioned already, modules are loaded by calling function jQuery.sap.require with the name of a required module. The framework then checks whether the named module is loaded already. If so, the function simply returns.
