In Chrome browser, just open chrome://inspect and click Inspect.

In VS Code, use the Debug: Attach to Node Process command.

If you executed cds watch on a standalone terminal, you can still attach a Node.js debugger to the process.

If you do this in VS CodeвЂ™s integrated terminal with the вЂAuto AttachвЂ™ feature enabled, debugging starts right away:

Similarly, debug-brk will start debug mode, but pause the application at the first line, so that you can debug bootstrap code. This restarts the application in debug mode. Use cds repl to live-interact with Node.js APIs.Use cds env to inspect currently effective config settings.Use cds add to gradually add features to projects.Use cds help or cds ? to get specific help.

Use cds help to see an overview of all commands.

Use cds version to get information about your installed package version.

To allow debugging of the currently opened file in the editor, modify the launch.json file by adding a new configuration, Launch Current File, for debugging the current file.Д¬onfiguration can be switched in the visual studio code editor by selecting the appropriate configuration.

outFiles вЂ“ specifies the location to the compiled files, that is, the build folder.

envFile вЂ“ specifies the location to the environment variables file.

program вЂ“ specifies the entry point to the application.

The following three properties where added to the file: In visual studio code, create a node.js launch.json file with the following Launch App configuration. Setting up debugging in visual studio code With the watch option enabled, babel will automatically compile a file every time it is changed. In a terminal or console, run the following command to compile the src folder and to output the compiled code to the build folder. The -watch option enables babel to compile a file every time it is changed. The -source-maps option generates source maps that can be used by the visual studio debugger. The above script will compile all the code in the src folder to a compatible JavaScript version (that is, version < es6) and output the compiled files to a folder called build. Open the package.json file and modify the scripts object as follows. npm install -save-dev a file in the root folder of the application with the below json. npm install -save-dev install -save-dev install -save-dev to install all dependencies in one command, run the below command. Run the below commands to install babel as a development dependency. env file to store environment variables as follows.Д«abel is a JavaScript compiler that is mainly used to convert ECMAScript2015+ code into a backwards compatible version of JavaScript in current and older browsers or environments. In the root folder of the project, create a. The expected result that is to be displayed in the console is 4.ДЄdd a breakpoint to line 3 in the server.js file. The result of the calculator will be outputted to the console. When the application is executed, a new calculator will be initialized and the add method will be invoked with two numbers, 1 and 3. Open the project in visual studio code and create an src folder with the following files.ДЄs can be seen from the above files, a simple calculator is created that adds two numbers. This article will present the steps required to get a simple node.js project running using es6+ features with debugging enabled in visual studio code.Д«efore proceeding with this article, ensure that you have node.js and visual studio code installed.Д¬reate a new project folder and navigate to it using a console or terminal. Two most common tools used to make these initial steps much more simpler are

to ensure debugging is enabled in the node.js project.

to ensure that the new es6+ features can be used, and.
