At the moment there are about 30 additions in the catalog, which were created over the past two months, by developers in collaboration with Google.



To install add-ons, it is necessary, being in any document or table, click on the new menu item “Add-ons” and select “Get add-ons”. Works for all accounts except Google Apps for Business accounts. For them promise to activate within the next 2 weeks.



After the add-on is installed, the corresponding item will appear in the Add-ons menu, by clicking on which the add-on panel will open. All that is in this panel is the domain of third-party developers.

Google has published guidelines and styles for creating add-ons. Their observance is one of the conditions for entering the add-ons catalog. Thanks to this, the add-ons are close to the native interface of Google Drive.

Add-ons are written in JavaScript, and the code is conventionally divided into server (has access to various Google API) and client parts (usual HTML, CSS, JS). In addition, the server part has the ability to send requests for third-party services. Google provides a development environment integrated into Google Drive. With auto-completion, debugging and versioning. Developing a project "locally", not in this development environment, unfortunately, is not yet possible.

More information about creating add-ons can be found in the documentation .
