Ember IntroJS wraps introjs in an Ember Component to guide users through your app.

Compatibility

  • Ember.js v2.18 or above
  • Ember CLI v2.13 or above
  • Node.js v8 or above

Installation

ember install ember-introjs

Usage

Use intro-js/step component as a wrapper

{{#intro-js/step step=1 intro="Step Component"}}
  <h1>Hello!</h1>
{{/intro-js/step}}

You can customize wrapper using:

  • position="top"
  • intro="Welcome!"
  • tooltipClass="tooltip-class"
  • highlightClass="highlight-class"
  • position="top"
  • hint="Use it :)"
  • hintPosition="bottom-left"

Options are documented in the code as well as in IntroJS Docs

2nd option

1. Declare your steps:

You can declare an array in JavaScript in your controller or parent component:

// app/controllers/ticket.js
import Controller from '@ember/controller';
import { computed } from '@ember/object';

export default Controller.extend({
  steps: computed(function() {
    return [
      {
        element: $('#step1'),
        intro: 'Step 1!'
      },
      {
        element: $('#step2'),
        intro: 'Step2!'
      }
    ];
  })
});

2. Use intro-js component

Then to use the steps, you can use the steps in your handlebars template:

{{! app/templates/ticket }}
{{intro-js start-if=true}}

Action Hooks

IntroJS supports a series of hooks for getting notified for when users switch between steps or exit. You can subscribe to these actions using the typical actions hash in your Route or Controller:

// app/routes/ticket.js
import Ember from 'ember';

export default Ember.Route.extend({
  actions: {
    introBeforeChange(previousStep, nextStep, introJSComponent,
elementOfNewStep){
      // You could track user interactions here, e.g. analytics.
      this.sendAnalytics(prevStep);
    }
  }
});

Then pass the name of the action in the handlebars helper that renders the component below.

{{intro-js steps=steps start-if=true on-before-change=(action "introBeforeChange")}}

on-before-change (currentStep, nextStep, introJSComponent, nextElement)

Called when the user clicks next (or uses their keyboard). Called before on-change. Given the currentStep, the nextStep, the introJSComponent, and the DOM element of the next step.

on-change (step, introJSComponent, currentElement)

Called after on-before-change when the user moves a step (backwards or forward) in the introduction. Gives the current step, the introJS component isntance, and the element of the current step.

on-after-change (step, introJSComponent, currentElement)

Called after on-change when the user moves a step (backwards or forward) in the introduction. Gives the current step, the introJS component isntance, and the element of the current step.

on-before-exit (step, introJSComponent)

Called when the user quits the intro via the "Skip" button, hitting escape, or clicking outside the overlay. Given the current step, and the introJS component.

on-exit (step, introJSComponent)

Called after on-before-exit when the user quits the intro via the "Skip" button, hitting escape, or clicking outside the overlay. Given the current step, and the introJS component.

on-complete (step, introJSComponent)

Called when the user finishes the intro by clicking "Done" or hitting right on the keyboard until the end. Called with the last step and the introJS component instance.

Intro JS Options

Intro JS has a variety of options available to it. You can see the full list here, but we also provided the full list below. You'll notice that in the list below options all follow the dasherized convention of HTML and ember-cli filenames. The original list uses camelCase names, and so does IntroJS. Ember IntroJS will do the conversion for you.

You can also set other options using the Handlebars helper syntax: `

{{intro-js steps=steps show-bullets=true}}

Or you could extend your own base class to override defaults instead of specifying them every time in the Handlebars helper:

myapp/app/components/my-intro-js.js
import IntroJSComponent from 'ember-introjs/components/intro-js';

export default IntroJSComponent.extend({
  'exit-on-esc': true
});

You can also reopen the class:

import IntroJSComponent from 'ember-introjs/components/intro-js';

IntroJSComponent.reopen({
  'exit-on-esc': true
});
