`luckysheet` stores all operations in the history to `undo` and `redo`. If `allowupdate` is set to true and `updateURL` is available in initial, operations will be updated on the backend in real-time via webSocket. And every one can edit same sheet on the same time.
## Cell refresh
>Source code [`src/controllers/server.js`] (https://github.com/mengshukeji/Luckysheet/blob/master/src/controllers/server.js) The module shows us the function of background saving.
In general, shared editing(or collaborative editing) is controled by the account system created by developers to control permissions.
The following are all types of operations that support transferring to the background. In this case, I use mongodb as a storage example to explain how front-end and back-end interacts with eachother.
Pay attention, `i` in the object is the `index` of the sheet rather than `order`.
