This repository will contain notes, files(?), and other information pertaining Visual Studio Code. There is no code here. Except where it is related to using Visual Studio Code.

Environment

OS: Windows 10 Professional

Application Type: Node.js + JavaScript

Visual Studio Code: v1.13.1

Node.js: v6.10.2, 8.9.0, 8.17.0

Launch JSON File

This file describes one or more methods that vscode will use when starting your program. The launch configurations described here will be for non-typical use.

Attach to Process ID

This method is useful when your Node.js script is expecting input from stdin (think "keyboard"). It is best debugging an already runnin Node.js instance. It is necessary to start the instance from within the same folder that vscode is referencing.

ATTACH - Running Node.js

The script test.js uses the following code to read from stdin:

process.stdin.on('data', function(inputStdin) {
    // check the EOLs for CRLF or just LF
    if(inputStdin.includes('\r')) {
        inputArray = inputStdin.split('\r\n');
    } else {
        inputArray = inputStdin.split('\n');
    }
    main();
});

Run with the following:

node --debug-brk test.js <input.txt

External Console

            "type": "node",
            "request": "launch",
            "externalConsole": true,
            "name": "Launch Program - test.js",
            "program": "${workspaceFolder}/test.js"
        }
     ]
}

Remote Debug

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "attach",
            "name": "Attach to Remote",
            "address": "192.168.0.1000",
            "port": 9229,

            "remoteRoot": "/volume1/NodeSrv/apps/test"
        }
    ]
}

Redirect input to test.js:

> node test.js <input.txt

Piping input to test.js:

type input.txt | node test.js
