ONLYOFFICE Cloud

You can add a plugin to the Cloud service as an extension. It can be done for Google Chrome, Opera, or Microsoft Edge browsers.

Step 1. Creating extensions

1. To create an extension, you need an account on GitHub. Sing in to an existing account or create a new one.

2. Fork the plugin marketplace repository: https://github.com/ONLYOFFICE/onlyoffice.github.io.

   You get a repository with the following address - https://github.com/YOUR-USERNAME/ONLYOFFICE/onlyoffice.github.io.

3. Build your own GitHub Pages site from this repository. Explore the official GitHub documentation to learn how to do it.

4. Clone the fork to your local computer.

5. Add the plugin folder to onlyoffice.github.io/sdkjs-plugins/content/ and push it to the remote repository.

   

6. Open the onlyoffice.github.io/store/plugin-dev/extension/inject.js file and assign the path to your plugin on GitHub Pages site to the URL_TO_PLUGIN variable:

   const URL_TO_PLUGIN = "https://YOUR-USERNAME.github.io/onlyoffice.github.io/sdkjs-plugins/content/helloworld/"
   

The onlyoffice.github.io/store/plugin-dev/extension folder is a new extension.

Please note that when adding an extension to ONLYOFFICE App Directory, the Title and Summary are filled in automatically with the name and description parameters from the manifest.json file. You cannot change them later in the store.
