You want to make a native wrapper for WhatsApp Web (or any web page).

nativefier web.whatsapp.com

You're done.

Nativefier is a command-line tool to easily create a desktop app for any web site with minimal configuration. Apps are wrapped by Electron (which uses Chromium under the hood) in an OS executable (.app, .exe, etc) for use on Windows, macOS and Linux.

I did this because I was tired of having to ⌘-tab or alt-tab to my browser and then search through the numerous open tabs when I was using Facebook Messenger or Whatsapp Web (HN thread). Nativefier features:

• Automatically retrieval of app icon / name.
• JavaScript and CSS injection.
• Many more, see the API docs or nativefier --help

• macOS 10.9+ / Windows / Linux
• Node.js >= 10 and npm >= 6
• Optional dependencies:
  • ImageMagick to convert icons. Make sure convert and identify are in your system $PATH.
  • Wine to package Windows apps under non-Windows platforms. Make sure wine is in your system $PATH.

npm install -g nativefier

To create a native desktop app for medium.com, simply nativefier "medium.com"

Nativefier will try to determine the app name, and well as lots of other options. If desired, these options can be overwritten. For example, to override the name, nativefier --name 'My Medium App' 'medium.com'

Read the API documentation or run nativefier --help to learn about other command-line flags usable to configure the packaged app.

To have high-resolution icons used by default for an app/domain, please contribute to the icon repository!

Help welcome on bugs and feature requests.
