During the development and testing phase of SAP UI5 applications, we often use a special HTML file called flpSandbox.html. This file is mainly used to simulate the Fiori Launchpad environment in the local environment, so that developers can develop and debug without real SAP system support.
The source code of this file can be found in the author's tutorial:
SAP Fiori Elements Development Tutorial - From Beginner to Master
Fiori Launchpad is SAP's portal platform, and users can access various Fiori applications through Fiori Launchpad. In Fiori Launchpad, each Fiori application exists in the form of a tile (the English term is tile). When the user clicks on this tile, the corresponding Fiori application can be launched.
For more introduction about Fiori Launchpad tile, refer to this article of the author:
The main function of the flpSandbox.html file is to simulate this Fiori Launchpad in the local environment. In this file we can configure some simulated Fiori tiles that link to the Fiori app we are developing. In this way, we can start and test our application in the local environment, just like it has been deployed to the real SAP system.
As an example, let's say we are developing a Fiori app called "MyApp". We can configure a simulated Fiori tile in the flpSandbox.html file that links to our "MyApp" application. We then open the flpSandbox.html file in a browser to see a simulated Fiori Launchpad interface with a tile linking to "MyApp". Click on this tile to launch the "MyApp" application.
The flpSandbox.html file serves a few other purposes besides simulating the Fiori Launchpad environment. For example, we can configure some simulated services and data in this file, so that we can simulate the behavior of the backend during the development and testing phases. In addition, we can also configure some running parameters of the application in this file, such as the language setting when starting the application, etc.
I observed file flpSandbox.html is loaded in SAP UI5 application startup phase. What’s the purpose of this file?
