javascript - How to launch a Chrome App from a Chrome Extension?

Question

Typically an app is opened from chrome://apps/ or in the button Chrome apps, but how would from an external Chrome Extension?

My extension:

->manifest.json
->background.js

My app:

->manifest.json
->background.js

Then, how to launch my app from my extension?

Answer 1

If you own both items you can just use messaging to open the app window when receiving a message from the extension. This does not have a permissions warning that will repel users like management. https://developer.chrome.com/extensions/messaging

First, add this to both manifests:

"externally_connectable": { "ids": [ "idoftheotheritem" ] }

Then, listen for messages in your app and create a app window:

chrome.runtime.onMessageExternal.addListener(function() {
  chrome.app.window.create("app.html");
}

Finally, send from the extension:

chrome.runtime.sendMessage("idoftheapp", { launch: true })
