Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

For Usage and Examples, have a look at demo

So, yet another tour library?

No, it is not. Tours are just one of the many use-cases. Driver.js can be used wherever you need some sort of overlay for the page; some common usecases could be: e.g. dimming the background when user is interacting with some component i.e. the way Facebook does when you try to create a post, using it as a focus shifter to bring user's attention to some component on page, or using it to simulate those "Turn off the Lights" widgets that you might have seen on video players online, etc.

Driver.js is written in Vanilla JS, has zero dependencies and is highly customizable. It has several options allowing you to manipulate how it behaves and also provides you the hooks to manipulate the elements as they are highlighted, about to be highlighted, or deselected.

Installation

You can install it using yarn or npm, whatever you prefer.

yarn add driver.js
npm install driver.js

Or include it using CDN. If you want a specific version, put it as [email protected] in the name

<script src="https://unpkg.com/driver.js/dist/driver.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/driver.js/dist/driver.min.css">

Or grab the code from dist directory and include it directly.

<link rel="stylesheet" href="/dist/driver.min.css">
<script src="/dist/driver.min.js"></script>

Usage and Demo

If you are using some sort of module bundler, import the library and the CSS file

import Driver from 'driver.js';
import 'driver.js/dist/driver.min.css';

otherwise use the script and link tags to import the JavaScript and CSS files.

Demos and many more usage examples can be found in the docs page.

Highlighting Single Element – Demo

You can highlight a single element by simply passing the selector.

const driver = new Driver();
driver.highlight('#create-post');

A real world usage example for this is: using it to dim the background and highlight the required element e.g. the way Facebook does it when creating a post.

Highlight and Popover – Demo

You can show additional details beside the highlighted element using the popover.

const driver = new Driver();
driver.highlight({
  element: '#some-element',
  popover: {
    title: 'Title for the Popover',
    description: 'Description for it',
  }
});

Also, title and description can have HTML as well.

Positioning the Popover – Demo

By default, driver automatically finds the suitable position for the popover and displays it. You can override it using position property.

const driver = new Driver();
driver.highlight({
  element: '#some-element',
  popover: {
    title: 'Title for the Popover',
    description: 'Description for it',
    // position can be left, left-center, left-bottom, top,
    // top-center, top-right, right, right-center, right-bottom,
    // bottom, bottom-center, bottom-right, mid-center
    position: 'left',
  }
});

You can also add offset to the popover position by using the offset property

const driver = new Driver();
driver.highlight({
  element: '#some-element',
  popover: {
    title: 'Title for the Popover',
    description: 'Description for it',
    position: 'bottom',
    // Will show it 20 pixels away from the actual position of popover
    // You may also provide the negative values
    offset: 20,
  }
});

Creating Feature Introductions – Demo

Feature introductions are helpful when onboarding new users and giving them an idea about different parts of the application; you can create them seamlessly with Driver. Define the steps and call the start when you want to start presenting. User will be able to control the steps using the keyboard or using the buttons on popovers.

const driver = new Driver();

// Define the steps for introduction
driver.defineSteps([
  {
    element: '#first-element-introduction',
    popover: {
      className: 'first-step-popover-class',
      title: 'Title on Popover',
      description: 'Body of the popover',
      position: 'left'
    }
  },
  {
    element: '#second-element-introduction',
    popover: {
      title: 'Title on Popover',
      description: 'Body of the popover',
      position: 'top'
    }
  },
  {
    element: '#third-element-introduction',
    popover: {
      title: 'Title on Popover',
      description: 'Body of the popover',
      position: 'right'
    }
  },
]);

// Start the introduction
driver.start();

You can also hide the buttons and control the introductions programmatically by using the API methods listed below.

Asynchronous Actions – Demo

For any asynchronous actions between the transition steps, you may delay the execution till the action completes. All you have to do is stop the transition using driver.preventMove() in your onNext or onPrevious callbacks and initiate it manually using driver.moveNext(). Here is a sample implementation where it will stop at the second step for four seconds and then move on to the next step.

const driver = new Driver();

// Define the steps for introduction
driver.defineSteps([
  {
    element: '#first-element-introduction',
    popover: {
      title: 'Title on Popover',
      description: 'Body of the popover',
      position: 'left'
    }
  },
  {
    element: '#second-element-introduction',
    popover: {
      title: 'Title on Popover',
      description: 'Body of the popover',
      position: 'top'
    },
    onNext: () => {
      // Prevent moving to the next step
      driver.preventMove();
      
      // Perform some action or create the element to move to
      // And then move to that element
      setTimeout(() => {
        driver.moveNext();
      }, 4000);
    }
  },
  {
    element: '#third-element-introduction',
    popover: {
      title: 'Title on Popover',
      description: 'Body of the popover',
      position: 'right'
    }
  },
]);

// Start the introduction
driver.start();

You can also hide the buttons and control the introductions programmatically by using the API methods listed below.

API

Driver comes with several options that you can manipulate to make Driver behave as you like

Driver Definition

Here are the options that Driver understands:

const driver = new Driver({
  className: 'scoped-class',        // className to wrap driver.js popover
  animate: true,                    // Whether to animate or not
  opacity: 0.75,                    // Background opacity (0 means only popovers and without overlay)
  padding: 10,                      // Distance of element from around the edges
  allowClose: true,                 // Whether the click on overlay should close or not
  overlayClickNext: false,          // Whether the click on overlay should move next
  doneBtnText: 'Done',              // Text on the final button
  closeBtnText: 'Close',            // Text on the close button for this step
  stageBackground: '#ffffff',       // Background color for the staged behind highlighted element
  nextBtnText: 'Next',              // Next button text for this step
  prevBtnText: 'Previous',          // Previous button text for this step
  showButtons: false,               // Do not show control buttons in footer
  keyboardControl: true,            // Allow controlling through keyboard (escape to close, arrow keys to move)
  scrollIntoViewOptions: {},        // We use `scrollIntoView()` when possible, pass here the options for it if you want any
  onHighlightStarted: (Element) => {}, // Called when element is about to be highlighted
  onHighlighted: (Element) => {},      // Called when element is fully highlighted
  onDeselected: (Element) => {},       // Called when element has been deselected
  onReset: (Element) => {},            // Called when overlay is about to be cleared
  onNext: (Element) => {},                    // Called when moving to next step on any step
  onPrevious: (Element) => {},                // Called when moving to previous step on any step
});

Note that all the button options that you provide in the driver definition can be overridden for a specific step by giving them in the step definition

Step Definition

Here are the set of options that you can pass while defining steps defineSteps or the object that you pass to highlight method:

const stepDefinition = {
  element: '#some-item',        // Query selector string or Node to be highlighted
  stageBackground: '#ffffff',   // This will override the one set in driver
  popover: {                    // There will be no popover if empty or not given
    className: 'popover-class', // className to wrap this specific step popover in addition to the general className in Driver options
    title: 'Title',             // Title on the popover
    description: 'Description', // Body of the popover
    showButtons: false,         // Do not show control buttons in footer
    doneBtnText: 'Done',        // Text on the last button
    closeBtnText: 'Close',      // Text on the close button
    nextBtnText: 'Next',        // Next button text
    prevBtnText: 'Previous',    // Previous button text
  },
  onNext: () => {},             // Called when moving to next step from current step
  onPrevious: () => {},         // Called when moving to previous step from current step
};

For example, here is how it would look when highlighting a single element:

const driver = new Driver(driverOptions);
driver.highlight(stepDefinition);

And this is how it would look when creating a step by step guide:

const driver = new Driver(driverOptions);
driver.defineSteps([
    stepDefinition1,
    stepDefinition2,
    stepDefinition3,
    stepDefinition4,
]);

API Methods

Below are the set of methods that are available:

const driver = new Driver(driverOptions);

// Checks if the driver is active or not
if (driver.isActivated) {
    console.log('Driver is active');
}

// In case of the steps guide, you can call below methods
driver.defineSteps([ stepDefinition1, stepDefinition2, stepDefinition3 ]);
driver.start(stepNumber = 0);  // Starts driving through the defined steps
driver.moveNext();             // Moves to next step in the steps list
driver.movePrevious();         // Moves to previous step in the steps list
driver.hasNextStep();          // Checks if there is next step to move to
driver.hasPreviousStep();      // Checks if there is previous step to move to

// Prevents the current move. Useful in `onNext` or `onPrevious` if you want to
// perform some asynchronous task and manually move to next step
driver.preventMove();

// Highlights the element using query selector or the step definition
driver.highlight(string|stepDefinition);

// Reposition the popover and highlighted element
driver.refresh();

// Resets the overlay and clears the screen
driver.reset();

// Additionally you can pass a boolean parameter
// to clear immediately and not do the animations etc
// Could be useful when you, let's say, want to run
// a different instance of driver while one was running
driver.reset(clearImmediately = false);

// Checks if there is any highlighted element
if(driver.hasHighlightedElement()) {
    console.log('There is an element highlighted');
}

// Gets the currently highlighted element on screen
// It would be an instance of `/src/core/element.js`
const activeElement = driver.getHighlightedElement();

// Gets the last highlighted element, would be an instance of `/src/core/element.js`
const lastActiveElement = driver.getLastHighlightedElement();

activeElement.getCalculatedPosition(); // Gets screen co-ordinates of the active element
activeElement.hidePopover();           // Hide the popover
activeElement.showPopover();           // Show the popover

activeElement.getNode();  // Gets the DOM Element behind this element

Note – Do not forget to add e.stopPropagation() to the click binding that triggers driver.
