useSearch

useSearch hook. A hook allowing you to Search your applicaiton

Usage

Hooks are a new addition in React. They let you use state and other React features without writing a class. To learn more abou hook in react please read : https://reactjs.org/docs/hooks-intro.html

The motivation for introducing hooks in React are:

• It’s hard to reuse stateful logic between components
• Complex components become hard to understand
• Classes confuse both people and machines
• Complex components become hard to understand

To solve these problems, Hooks let you use more of React’s features without classes.

We have tried to expose hooks used in the libary so that you can create your own visualisations if you wish.

import { useSearch } from @motor-js/core
//...
  const { searchResults, select } = useSearch({
    engine,
    searchValue,
    dimensions,
    qCount,
    qGroupItemCount,
  });

Once data has been retrived from the search hook it can then pass it on to an object to render its contents.

Props

You do not need to set the Config prop if the component is a child of the Motor component
