Node CLI tool to disable darkmode on specific apps

lightmode.js

#!/usr/bin/env node
const path = require('path')
const { execSync } = require('child_process')

/*
* You can symlink this to a bin dir e.g. "ln -s /Users/owen/lightmode.js /usr/local/bin/lightmode"
* To enable lightmode for an app, simply pass the full path to the application to lightmode e.g.
*
* lightmode /Application/Google\ Chrome.app
*
* You can even drag the app icon straight into your terminal to get the full path.

const appPath = process.argv.pop()
const appName = path.basename(appPath, '.app')

// Open the app so it's accessible by osascript.
execSync(`open "${appPath}"`)

// Extract the application ID.
const appId = execSync(`osascript -e 'id of app "${appName}"'`, {
    encoding: 'utf8',
}).toString().trim()

// Tell the OS to disable darkmode.
execSync(`defaults write ${appId} NSRequiresAquaSystemAppearance -bool Yes`)

// Now we restart the application.
execSync(`pkill "${appName}"`)
execSync(`open "${appPath}"`)
