i i use "react-video-thumbnail-image" the video thumbnail is generated on each render of the component. But it only should render one time and not again.

How can i do that?

CodePudding user response：

You have several options to control re-rendering.

For class components:

• shouldComponentUpdate (https://reactjs.org/docs/react-component.html#shouldcomponentupdate)
• React.PureComponent (https://reactjs.org/docs/react-api.html#reactpurecomponent)

For functional components:

• React.memo() (https://reactjs.org/docs/react-api.html#reactmemo)

Here is the Problem, React.memo does not solve the problem. All the time i reorder the list, the VideoThumbnail-Element is rerendered.
