Adding plugins to ONLYOFFICE Cloud

You can add a plugin to the Cloud service as a Chrome extension.

1. Create a main folder on your computer and put manifest.json and main.js extension files.
2. Create a subfolder with the plugin files.

3. In the main.js file, change the directory to the necessary plugin:

   (function(window, undefined){
       if ("frameEditor" == window.name)
       {
           var _url = chrome.extension.getURL("main.js");
           _url = _url.substr(0, _url.lastIndexOf("main.js"));
           var _baseUrl = _url + "helloworld/";
           var _configUrl = _baseUrl + "config.json";
           ...
       }
   })(window, undefined);
   

4. Change the plugin name and description, the paths to the plugin icons and all the necessary plugin resources in the manifest.json file:

   {
       "name": "Asc.helloworld",
       "description": "Plugin for ONLYOFFICE. helloworld",
       "version": "1.0",
       "manifest_version": 2,
       "background": {
       },
       "browser_action": {
           "default_icon": {
               "19": "/helloworld/resources/img/icon.png",
               "38": "/helloworld/resources/img/icon@2x.png"
           }
       },
       "web_accessible_resources": [
           "/main.js",
           "/helloworld/scripts/helloworld.js",
           "/helloworld/config.json",
           "/helloworld/resources/img/icon.png",
           "/helloworld/resources/img/icon@2x.png",
           "/helloworld/index.html",
           "/helloworld/index_about.html"
       ],
       ...
   }
   

5. Launch your Chrome browser and go to chrome://extensions/. Turn on the Developer mode, click the Load unpacked button and select the created main extension folder:
