chrome.runtime.connectNative generates Uncaught TypeError: undefined is not a function
connectNative() is not available in a content scripts. To connect to a local program the content script must send the data e.g. to the background script of the extension and in the background script, port = chrome.extension.connectNativecan be used.So here a solution:
contentscript.js:
....// send data to background scriptchrome.extension.sendRequest("Some Data");....background.js:
function connect() { // connect to local program com.a.chrome_interface port = chrome.extension.connectNative('com.a.chrome_interface'); port.onMessage.addListener(onNativeMessage); port.onDisconnect.addListener(onDisconnected);}chrome.extension.onRequest.addListener(function(data, sender) { if (data.length > 0) { connect(); sendNativeMessage(data); }});manifest.json as above in my question but additionaly:
... "background": { "scripts": ["background.js"] },...com.a.chrome_interface.json is unchange as in the question above.
