react-change-highlight

React component to highlight changes in the wrapped component to enhance the UX and grap the focus of the user into the changed value of some parts like the cart in an e-commerce application for example.

Install

or

npm install react-change-highlight

Usage

Basically you need to wrap the components you want to highlight on change inside HighlightChange element then add ref attribute to each child in this component to be used to be highlighted.

In the following example the count variable comes from state, so when ever that function setCount() is called with any different value the background of that wrapped div will be changed

import ChangeHighlight from 'react-change-highlight';

export default () => {
  const [count, setCount] = useState(0);

  <ChangeHighlight>
    <div ref={React.createRef()}>{count}</div>
  </ChangeHighlight>
}

Default styling for highlighting in case the user didn't use a custom styling using the highlightStyle property:

.react-highlight {
    background-color: #f8ffb4;
    transition: all 0.5s ease-in-out;
  }
