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 or GraphicsMagick to convert icons. Make sure convert and identify or gm are in your system $PATH.
  • Wine to package Windows apps under non-Windows platforms. Make sure wine is in your system $PATH.

Then, install Nativefier globally with 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!

Nativefier is also usable from Docker.

• Pull the latest stable image from Docker Hub: docker pull nativefier/nativefier
• ... or build the image yourself: docker build -t local/nativefier . (in this case, replace nativefier/ in the below examples with local/)

By default, the command nativefier --help will be executed. To build e.g. a Gmail nativefier app to a writable local ~/nativefier-apps,

docker run --rm -v ~/nativefier-apps:/target/ nativefier/nativefier https://mail.google.com/ /target/

You can pass Nativefier flags, and mount volumes to provide local files. For example, to use an icon,

docker run --rm -v ~/my-icons-folder/:/src -v $TARGET-PATH:/target nativefier/nativefier --icon /src/icon.png --name whatsApp -p linux -a x64 https://web.whatsapp.com/ /target/

Before submitting a question or bug report, please ensure you have read through these common issues and see if you can resolve the problem on your own. If you still encounter issues after trying these steps, or you don't see something similar to your issue listed, please submit a bug report.

This issue comes up for sites that do not wish to support an app made with Nativefier or similar technologies (such as Google and WhatsApp)

1. First try setting the --user-agent to something different. Try using the value you would get at [https://www.whatismybrowser.com/detect/what-is-my-user-agent] and use your current browser's user agent.
2. If this doesn't work, the site (such as WhatsApp) may be using a service worker to analyze the app and detect. You can disable the service worker cache by doing the following, which is a known fix for WhatsApp:
   1. Create a javascript file containing the following snippet:

      if ('serviceWorker' in navigator) {
          caches.keys().then(function (cacheNames) {
              cacheNames.forEach(function (cacheName) {
                  caches.delete(cacheName);
              });
          });
      }

   2. Inject the javascript file into your app when generating it with the --inject argument.

This issue comes up for certain sites like HBO Max and Udemy.

1. First try using the --widevine argument when building the app. This uses the Castlabs version of Electron which allows the playback of DRM enabled video.
2. If this doesn't work, the site may require your app to be signed for --widevine to work. See the Castlabs documentation on using their application signing service to sign the application.

This issue can occur because the cache of the app and the app itself are kept separate by default. You can try clearing out the cache.

1. Delete your app's cache, which can be found under the folder <your_app_name_lower_case>-nativefier-<random_id> in your OS's app data directory
   • <your_app_name_lower_case> represents the lowercase version of your app's name. E.g., GitHub would be github.
   • <random_id> represents a randomly generated id for your app. Open the containing folder to see what it may be.
2. For Linux, the app data directory is $XDG_CONFIG_HOME or ~/.config
3. For MacOS, the app data directory is ~/Library/Application\ Support/
4. For Windows, the app data directory is %APPDATA%
