React Native: Using lodash debounce

by

Debounce function should be defined somewhere outside of render method since it has to refer to the same instance of the function every time you call it as oppose to creating a new instance like it’s happening now when you put it in the onChangeText handler function.

The most common place to define a debounce function is right on the component’s object. Here’s an example:

class MyComponent extends React.Component {
  constructor() {
    this.onChangeTextDelayed = _.debounce(this.onChangeText, 2000);
  }

  onChangeText(text) {
    console.log("debouncing");
  }

  render() {
    return <Input onChangeText={this.onChangeTextDelayed} />
  }
}
