       // Use IntelliSense to learn about possible Node.js debug attributes.
       // Hover to view descriptions of existing attributes.
       // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
       "version": "0.2.0",
       "configurations": [
           {
               "type": "node",
               "request": "launch",
               "name": "Launch Program",
               "program": "${workspaceRoot}/bin/www",
               "cwd": "${workspaceRoot}",
               "skipFiles": [
                   "node_modules/**" // Intentionally doesn't match `http` module
               ]
           },
           {
               "type": "node",
               "request": "attach",
               "name": "Attach to Process",
               "port": 5858
           }
