runtime.Port object to the caller.Port to exchange messages with the native application using Port.postMessage() and port.onMessage.Port.disconnect(), or the page that created the Port is destroyed. Once the Port is disconnected the browser will give the process a few seconds to exit gracefully, and then kill it if it has not exited.For more information, see Native messaging.
Syntax

This API is also available as browser.runtime.connectNative().
Parameters
applicationstring. The name of the native application to connect to. This must match the "name" property in the native application's manifest file.
Return value
A runtime.Port object. The port which the caller can use to exchange messages with the native application.

Examples
This example connects to the native application "ping_pong" and starts listening for messages from it. It also sends the native application a message when the user clicks a browser action icon:
/*
On startup, connect to the "ping_pong" app.
*/
var port = chrome.runtime.connectNative("ping_pong");
/*
Listen for messages from the app.
*/
port.onMessage.addListener((response) => {
console.log("Received: " + response);
});
/*
On a click on the browser action, send the app a message.
*/
chrome.browserAction.onClicked.addListener(() => {
console.log("Sending: ping");
port.postMessage("ping");
});
