This topic provides an overview of files used to develop DataV widgets.
Before you develop widgets, you must create a folder to serve as the widget package. We recommend that you use the widget name to name the package. A widget package contains the following files.
|index.js||The API of the widget.|
|package.json||The settings of the widget.|
|readme.md||The description of the widget.|
|history.md||The update history of the widget.|
