Native Messaging is a Chrome-specific mechanism that allows Chrome extensions to communicate with Native applications running on the host machine.

Native Messaging is a Chrome-specific mechanism that allows Chrome extensions to communicate with native applications running on the host machine. The communication is done via standard in/out streams. This mechanism is supported for Windows, Mac and Linux operating systems.

This feature of Chrome allows developers to reach beyond the limits of the browser and into the host machine's domain (albeit in a limited fashion). The traditional way to do this was using the deprecated NPAPI plugin technology.

The documentation at https://developer.chrome.com/extensions/nativeMessaging includes examples and debugging tips. Check them out before posting a new question.
