This is not an exhaustive list. Download and install the launcher to gauge all it can do!

You can download from GitHub Releases

Supported Platforms

If you download from the Releases tab, select the installer for your system.

To open the console, use the following keybind.

ctrl + shift + i

Ensure that you have the console tab selected. Do not paste anything into the console unless you are 100% sure of what it will do. Pasting the wrong thing can expose sensitive information.

If you want to export the console output, simply right click anywhere on the console and click Save as..

All development of the launcher should be done using Visual Studio Code.

Paste the following into .vscode/launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Main Process",
      "type": "node",
      "request": "launch",
      "cwd": "${workspaceRoot}",
      "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron",
      "windows": {
        "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron.cmd"
      },
      "args": ["."],
      "console": "integratedTerminal",
      "protocol": "inspector"
    },
    {
      "name": "Debug Renderer Process",
      "type": "chrome",
      "request": "launch",
      "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron",
      "windows": {
        "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron.cmd"
      },
      "runtimeArgs": [
        "${workspaceRoot}/.",
        "--remote-debugging-port=9222"
      ],
      "webRoot": "${workspaceRoot}"
    }
  ]
}

This adds two debug configurations.

This allows you to debug Electron's main process. You can debug scripts in the renderer process by opening the DevTools Window.

This allows you to debug Electron's renderer process. This requires you to install the Debugger for Chrome extension.

Note that you cannot open the DevTools window while using this debug configuration. Chromium only allows one debugger, opening another will crash the program.
