Configure IDE to Debug Node.js Functions

For the purposes of this help documentation we are going to illustrate how to configure debugging preferences of Node.js non-HTTPS and Integration functions in Visual Studio Code.

Configure your VS Code IDE’s debugger in the following manner:

1. Ensure you have all the functions you need to debug in the local machine, and open the concerned project in VS Code.
   

2. Click the Run/Debug button present in the menu-bar and create a launch.json file, by clicking the “create a launch.json file” option.
   

This is how the launch.json file appears before you begin configurations.

3. Copy the JSON snippet below and paste it as value in the “configurations” JSON key.

    

        
launch.json
        

            
copy
            

                

            
        
    
    

    

         "configurations": [{
			"name": "cron_fun",  // name can be any name but having the same function name will be helpful while debugging
            		"type": "node",
            		"request": "attach",
            		"address": "localhost",
          		  "port": 9001, // The debug port number you specified in the catalyst functions:shell --tunnel 8001 --debug 9001. The port number can be any number which is not being used by any other processes
            		"localRoot": "/Users/jack/tun_cli/functions/cron_fun" //Exact path where the function folder is present
    }],

    

4. Save this file and apply the breakpoints in your required lines of code and proceed to the next step.
