React Likert Scale

React Likert Scale is a React component that renders a Likert Scale. It is fully responsive, very small size (about 9kb), and the styling can be customized by providing your own CSS styles.

Installation

npm install -P react-likert-scale

Usage

import React from 'react';
import Likert from 'react-likert-scale';

export default () => {
  const likertOptions = {
    question: "What is your opinion of the President’s performance?",
    responses: [
      { value: 1, text: "Abysmal" },
      { value: 2, text: "Poor" },
      { value: 3, text: "Average" },
      { value: 4, text: "Good" },
      { value: 5, text: "Excellent" }
    ],
    picked: val => {
      console.log(val);
    }
  };
  return (
    <Likert {...likertOptions} />
  )
}

Likert Props

This component has three props:

  • question — (string) This is the prompt that displays above the options.
  • responses — (array of objects) These are your options. The value key is what is returned to the calling application in the picked callback.
  • picked — (callback function) Optionally, you can provide a callback function that returns the value of the option that was clicked.

FAQ

How do I change colors or other CSS styling?

The top-level DOM element that gets created by this component is <fieldset class="likertScale">. You can override any styles by prefixing your rule with fieldset.likertScale. For example, let’s say you want the radio button “dots” to have a light gray background with a dark green ring.

fieldset.likertScale .likertIndicator {
  border: thin solid darkGreen;
  background-color: lightGray;
}

I need access to the DOM element created by React. How is that done?

This isn’t very common, but you may want to set focus on a Likert Scale after the page renders. This is done with React via refs. Either create your ref with React.createRef() or the useRef() hook. You can then pass your ref to the Likert component.

import React, { useRef } from 'react';
import Likert from 'react-likert-scale';

export default () => {
  const likertOptions = {
    question: "What is your opinion of the President’s performance?",
    responses: [
      { value: 1, text: "Abysmal" },
      { value: 2, text: "Poor" },
      { value: 3, text: "Average" },
      { value: 4, text: "Good" },
      { value: 5, text: "Excellent" }
    ]
  };

  const likertRef = useRef();

  return (
    <Likert {...likertOptions} ref={likertRef} />
  )
}

Can I pass in DOM attributes such as id, class, disabled, data-*, onClick, etc.?

Sure. They will be applied to the likert component’s top-level DOM element, <fieldset>. e.g.:

<Likert {...likertOptions}
  id='Q1'
  className='myClass'
  onClick={() => {
    doThis();
    andThis();
  }}
/>
