Quicklinks

Example

You can find a small example here on codesandbox.io.

Installation

Install using Npm (don't forget to add the --save option if you're still using npm < 5):

$ npm install intro.js-react

Or Yarn:

$ yarn add intro.js-react

Make sure to have React & Intro.js installed (they're peer dependencies) and the Intro.js CSS definitions properly loaded into your project.

This would usually looks like:

import 'intro.js/introjs.css';

Usage

Two component are available for both steps and hints:

import { Steps, Hints } from 'intro.js-react';

Steps

Note: Steps indexes always starts from 0 in this wrapper instead of 1 like in Intro.js.

Basic example:

<Steps
  enabled={stepsEnabled}
  steps={steps}
  initialStep={initialStep}
  onExit={this.onExit}
/>

Step

const steps = [
  {
    element: '.selector1',
    intro: 'test 1',
    position: 'right',
    tooltipClass: 'myTooltipClass',
    highlightClass: 'myHighlightClass',
  },
  {
    element: '.selector2',
    intro: 'test 2',
  },
  {
    element: '.selector3',
    intro: 'test 3',
  },
];
Name Description Type Required
element CSS selector to use for the step. String
intro The tooltip text. String
position Position of the tooltip. String
tooltipClass CSS class of the tooltip. String
highlightClass CSS class of the helperLayer. String

Dynamic elements

If you want to use Intro.js Steps with dynamically created elements, you have to update the element associated to the step when it's available.

To do that, you can use the updateStepElement() API and pass to it the index of the step to update:

<Steps
  enabled={stepsEnabled}
  steps={steps}
  ref={steps => (this.steps = steps)}
/>
onBeforeChange = nextStepIndex => {
  if (nextStepIndex === 4) {
    this.steps.updateStepElement(nextStepIndex);
  }
}

Hints

Basic example:

<Hints
  enabled={hintsEnabled}
  hints={hints}
/>

Props

Name Description Type Required
enabled Defines if the hints are visible or not.
Default: false.
Boolean
hints All the hints. Hint[]
onClick Callback called when a hint is clicked. Function
( )
onClose Callback called when a hint is closed. Function
( )
options Intro.js options. Object

Hint

const hints = [
  {
    element: '.selector1',
    hint: 'test 1',
    hintPosition: 'middle-middle',
  },
  {
    element: '.selector2',
    hint: 'test 2',
  },
];
Name Description Type Required
element CSS selector to use for the hint. String
hint The tooltip text. String
hintPosition Position of the tooltip. String

Intro.js API

If for some reasons you need to use the Intro.js API, you can still get the Intro.js instance by using a ref on either the <Steps /> or <Hints /> components and using this.refName.introJs.

<Hints
  enabled={hintsEnabled}
  steps={hints}
  ref={hints => (this.hints = hints)}
/>

You can find more details regarding Intro.js options and their default values in the documentation or directly in their code.

The wrapper overrides some Intro.js default options in the helpers/defaultProps.js file.
