How to test a Chrome App locally?

[张华]

I've generated a crx package locally. When I drag it into chrome://apps page, Chrome reports a warning 'Apps, extensions, and user scripts cannot be added from this website.'.

If I drag the crx package into chrome://extensions page, it works well on the extensions page. However, I can't see the icon on the apps page. Hence, I'm still not able to launch the app.

I'm wondering if Google has enhanced the security check so that I must upload my app to the Google store and download it from there. Otherwise, I can't launch the app.

Anyone has any ideas? Thanks a lot.

When you load it as an unpacked extension (I know it is an application, but I think it is the same in this regard), does it work?

chrome:extensions

Tick "Developer mode" on the right top corner.

Click on "Load unpacked extension..." and select the folder that contains manifest.json.

No, it doesn't. BTW, my manifest.json looks like below:

{

   "manifest_version": 2,

   ...

   "background": {

      "scripts": ["main.js"],

      "persistent": false

   },

   "permissions": [

      "storage",

      "webview",

      "fullscreen"

   ],

   ...

}

If I enclose 'background' into 'app' scope like below, I'm able to upload the app in the Chrome://extensions page and is able to see the app in the apps tab.

{

   "manifest_version": 2,

   ...

   "app": {

      "background": {

         "scripts": ["main.js"],

         "persistent": false

      }

   },

   "permissions": [

      "storage",

      "webview",

      "fullscreen"

   ],

   ...

}

But the problem with above manifest.json is I'm not able to package the app into crx on the Linux platform. When I run following command on Linux 64 machine:

/opt/google/chrome/google-chrome --pack-extension=XXX --pack-extension-key=XXX

I always get error "Either 'app.launch.local_path' or 'app.launch.web_url' is required.".

Looks like you have not structured your manifest well.

Look at the various examples at https://github.com/GoogleChrome/ (anything that ends with -app, I guess) for reference implementations.
