Installation

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

``sh
$ npm install intro.js-react
`

Or Yarn:


`sh
$ 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:

`js
import 'intro.js/introjs.css';
`

Usage

Two component are available for both steps and hints:

`js
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.

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:

`js
enabled={stepsEnabled}
steps={steps}
ref={steps => (this.steps = steps)}
/>
`

`js
onBeforeChange = nextStepIndex => {
if (nextStepIndex === 4) {
this.steps.updateStepElement(nextStepIndex);
}
}
`

Hints

`js
enabled={hintsEnabled}
hints={hints}
/>

| onClick | Callback called when a hint is clicked. | Function
( ) | |
| onClose | Callback called when a hint is closed. | Function

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 or components and using this.refName.introJs.

`js
enabled={hintsEnabled}
hints={hints}
ref={hints => (this.hints = hints)}
/>
`
