What are the steps to debug a Node.js application using SAP Web IDE for SAP HANA? There are 3 correct answers to this question.
Correct Answer: A,B,E
To debug a Node.js application using SAP Web IDE for SAP HANA, you need to perform the following steps:
* Open the debugger. You can open the debugger from the toolbar by clicking the \uE921 (debugger) icon, or from the menu by choosing Tools Debugger . The debugger opens in a new browser tab and shows a list of all Node.js modules in your project, as well as the available debug configurations.
* Attach the debugger to the node module. You can attach the debugger to any running Node.js module in your project by selecting the module name and clicking the \uE921 (attach) icon. Alternatively, you can create a new debug configuration for the module by clicking the \uE921 (create) icon and specifying the module name, the port number, and the source mapping. The debugger will connect to the Node.js module and switch it to debug mode.
* Set a breakpoint in the application. You can set a breakpoint in the application code by opening the file in the editor and clicking the left margin next to the line number where you want to pause the execution.
A red dot will appear to indicate the breakpoint. You can also use the \uE921 (breakpoints) pane to view, enable, disable, or remove breakpoints.
* Run the application. You can run the application from the browser by clicking the application URL in the run console, or from the command line by using the cf CLI commands. The application will execute until it reaches a breakpoint or an exception, and then pause and show the current state of the variables, call stack, and watch expressions in the debugger.
* Debug the application. You can use the debugger to inspect and modify the variables, evaluate expressions, step over, step into, step out, or resume the execution, as well as view the console output and the server log. You can also detach the debugger from the module by clicking the \uE921 (detach) icon, or stop the module by clicking the \uE921 (stop) icon.
The other option is incorrect because you do not need to specify the proper Git repository in the debug properties. The Git repository is used to manage the source code of the application, but it is not relevant for the debugging process. You also do not need to build the application with the debug option, because the debugger can attach to any running Node.js module without any special build settings. References:
