Native Messaging

This directory contains an example of Chrome extension that uses Native Messaging to communicate with a native application.

Running this extension

  1. Clone this repository.
  2. Load this directory in Chrome as an unpacked extension.
  3. Follow the installation instructions below.
  4. Open the popup.
  5. Send messages from either the native application or extension.

To install the host:

Windows

Run install_host.bat script in the host directory.

This script installs the native messaging host for the current user, by creating a registry key HKEY_CURRENT_USER\SOFTWARE\Google\Chrome\NativeMessagingHosts\com.google.chrome.example.echo and setting its default value to the full path to host\com.google.chrome.example.echo-win.json.

If you want to install the native messaging host for all users, change HKCU to HKLM.

Note that you need to have Python installed.

Mac and Linux

Run install_host.sh script in the host directory: host/install_host.sh

By default the host is installed only for the user who runs the script, but if you run it with admin privileges (i.e. sudo host/install_host.sh), then the host will be installed for all users. You can later use host/uninstall_host.sh to uninstall the host.
