TutorialScreen

A lightweight, zero-dependency JavaScript library for creating interactive, step-by-step product tours.

Created by Mark Gondelman.

Features

• Lightweight: Zero external dependencies for the end-user (Optional Hammer.js support for swipes).
• Zero-Dependency: No runtime dependencies required to use the library on your webpage.
• Customizable: Control transitions, colors, and positioning via options or CSS.
• Responsive: Handles window resizing and maintains target anchoring.
• Multi-Format: Distributed as IIFE and ES Modules (minified and non-minified versions included). Available for both JavaScript and TypeScript environments.
• JavaScript & TypeScript Support: Choose between src/tutorial.js and src/tutorial.ts. Both produce the same high-quality bundles.
• TypeScript Ready: Includes full type definitions (.d.ts) for a better development experience.
• Lifecycle Hooks: onTipLoad and onTipClose hooks for advanced page interaction.
• Modern Build: Developed in a single source file and built for multiple environments.

Installation

You can include the pre-built files from the dist folder.

JavaScript (IIFE)

<linkrel="stylesheet" href="styles/tutorial.css"><!-- Choose between JS-built or TS-built bundles --><scriptsrc="dist/tutorial.js.min.js"></script><!-- OR --><scriptsrc="dist/tutorial.ts.min.js"></script>

JavaScript / TypeScript (ES Module)

// From JavaScript buildimport{TutorialScreen}from'./dist/tutorial.js.esm.min.js';// OR from TypeScript build (includes types automatically)import{TutorialScreen}from'./dist/tutorial.ts.esm.min.js';

Quick Start

Define your stages and launch the tour:

constmyTour=[{name: 'Welcome',content: 'Welcome to our app!',target: null// Centered on screen},{name: 'Dashboard',content: 'This is where you see your data.',target: '#dashboard-id'// Element ID or CSS selector to highlight}];TutorialScreen.startTutorial(myTour);

Configuration Options

Option	Default	Description
BASE_SLEEP	350	Delay before tip starts moving.
BASE_SLEEP_EXPOSITION	550	Delay after tip moved and before exposition.
BASE_SLEEP_ARROW_ADD	560	Delay before adding the arrow.
FAST_SLEEP	50	Faster delay before tip starts moving.
FAST_SLEEP_EXPOSITION	150	Faster delay after tip moved and before exposition.
FAST_SLEEP_ARROW_ADD	260	Faster delay before adding the arrow.
VERTICAL_SPACING	20	Vertical padding between tip and target.
HORIZONTAL_SPACING	20	Horizontal padding between tip and target.
SHOW_TIP_NAMES	true	Display the stage name in the header.
SHOW_TIP_COUNT	true	Display '1/5' step indicator.
SHOW_INTERNAL_NAVIGATION	true	Show side buttons inside the tip.
SHOW_INTERNAL_CLOSE_BUTTON	true	Show 'x' close button in the tip.
ADD_SWIPE_ACTIONS	true	Enable swipe gestures (requires Hammer.js).
CLOSE_ON_ESCAPE	true	Close tour when Escape key is pressed.
DEFAULT_T_LINK	'styles/tutorial.css'	Default path to the library CSS file.
DEFAULT_THEME	'light'	Default theme applied (internal).
THEME_CLASS_NAME	'light'	Default global theme class name.
DEFAULT_TUTORIAL	[...]	Default stage if none provided to startTutorial.

Update options using:

TutorialScreen.setTutorialOptions({THEME_CLASS_NAME: 'dark-mode'});

Advanced Theming

You can apply different themes and classes to specific stages or elements.

Important: For custom theme classes to be correctly removed during transitions (in between stages), they must contain the string "theme" in their class name (e.g., my-custom-theme, theme-dark, solarized-theme).

constmyTour=[{name: 'Stage 1',content: 'Custom theme for this stage',target: '#target',// Element ID or CSS selector to highlightthemeClassName: 'my-custom-theme'// Overrides global THEME_CLASS_NAME},{name: 'Stage 2',content: 'Fine-tuned classes for elements',target: '#target2',// Element ID or CSS selector to highlightadditionalTipClassName: 'special-theme-tip',// Note 'theme' in nameadditionalVeilClassName: 'special-theme-veil',additionalVeilControlClassName: 'special-theme-controls'}];

Lifecycle Hooks

onTutorialClose

Fires when the entire tutorial is closed.

TutorialScreen.setOnTutorialClose(()=>{console.log('User finished the tour!');});

onTipLoad & onTipClose

These hooks can be defined for each stage of the tutorial to handle logic specific to that step.

• onTipLoad: Executes when the stage starts rendering.
• onTipClose: Executes when the stage is about to be replaced by the next one or when the tutorial is closed.

constmyTour=[{name: 'Interaction',content: 'Observe the change!',target: '#my-element',// Element ID or CSS selector to highlightonTipLoad: ()=>{document.querySelector('#my-element').classList.add('active');},onTipClose: ()=>{document.querySelector('#my-element').classList.remove('active');}}];

Dependencies

• End-Users: Zero external dependencies. If you are using the pre-built files from the dist folder, you don't need to install anything. Simply include the script and style on your page.
• Developers: If you want to modify the source code or re-build the project using Rollup, you will need to install the devDependencies listed in package.json (Rollup, Babel, Terser, etc.) via npm install.

Development

This project uses Rollup for building. Building is only necessary if you plan to modify the library's features.

1. Install development dependencies: npm install
2. Build the library: npm run build
3. Watch mode for development: npm run dev

Examples

The examples folder contains several demonstrations of how to use the library:

• Basic:
  • Standard IIFE Load
  • ES Module Load
• Advanced:
  • Scripted Interactions
  • Custom Themes (Dark Mode, Global vs Stage)
  • Multiple Themes & Fine-tuning (Solarized, Forest)
  • Lifecycle Hooks (onTipLoad, onTipClose)
