shallow-compare

Stand alone shallowCompare for use in libraries that support shouldComponentUpdate

API

shallowCompare(instance, nextProps, nextState)

• instance (component instance) - the component's instance (this)
• nextProps (object) - the next props
• nextState (object) - the next state

Example

class Foo extends Component {
  constructor (props) {
    super(props);
    this.state = { color: 'blue' }
  }

  shouldComponentUpdate (nextProps, nextState) {
    return shallowCompare(this, nextProps, nextState)
  }

  render () {
    return (
      <div>{this.state.color}</div>
    )
  }
}
