Great article. Just an update: as of serverless 1.40.0 and VS Code 1.32.3, you need to set "autoAttachChildProcesses": true in your launch.json for the debugger to work correctly.

Also a trick that I found useful is to put every function in a file with the same name (directory structure doesn’t matter), then use "-f", "${fileBasenameNoExtention}" in the args instead of "-f", "hello" . This way you can just open the file you want to debug in a tab and press F5 and debug it instead of hard coding the function name in launch.json or making one launch configuration for every function.
