Lodash debounce with React Input

I\'m trying to add debouncing with lodash to a search function, called from an input onChange event. The code below generates a type error \'function is expected\', which I unde

Answer 1

The debounce function can be passed inline in the JSX or set directly as a class method as seen here:

search: _.debounce(function(e) {
  console.log('Debounced Event:', e);
}, 1000)

If you're using es2015+ you can define your debounce method directly, in your constructor or in a lifecycle method like componentWillMount.

Examples:

class DebounceSamples extends React.Component {
  constructor(props) {
    super(props);

    // Method defined in constructor, alternatively could be in another lifecycle method
    // like componentWillMount
    this.search = _.debounce(e => {
      console.log('Debounced Event:', e);
    }, 1000);
  }

  // Define the method directly in your class
  search = _.debounce((e) => {
    console.log('Debounced Event:', e);
  }, 1000)
}
