SCOBot - Modern SCORM Library for Content Creation

Links: SCOBot Platform · SCOBot at Cybercussion · Documentation Wiki · SCOBOT.md (agent integration contract)

Overview

SCOBot 5 is a modernized, native JavaScript library for SCORM 1.2 and 2004 (2nd, 3rd, 4th Edition). It simplifies the complexity of the SCORM Run-Time Environment (RTE) by providing a robust, object-oriented interface for content developers.

Key Features:

• Modern Syntax: Written in ES6+ (Classes, Modules).
• Module Support: First-class support for generic bundlers (Vite, Webpack, Rollup) and native <script type="module">.
• SCORM Polyfill: Automatically bridges SCORM 1.2 calls to 2004 syntax, allowing you to write one codebase for multiple standards.
• Local Persistence: Built-in Mock LMS with localStorage persistence for developing offline or without an LMS.
• Data Compression: Optional integration with lz-string to compress suspend_data, maximizing storage limits.

Installation

Method 1: NPM / Bundlers

npm install @cybercussion/scobot

import { SCOBot } from '@cybercussion/scobot';

Method 2: Browser (Script Tag)

Use the production-ready UMD bundle.

<script src="dist/scobot.umd.cjs"></script>
<!-- Exposes window.SCOBot as a namespace object: { SCOBot, SCOBotBase, SCOBotUtil, SCOBot_API_1484_11 } -->
<script>
  const { SCOBot } = window.SCOBot;   // unwrap the constructor
</script>

Quick Start

Check out the index.html file in the root directory for a complete, working boilerplate.

// 1. Initialize
const scobot = new SCOBot({
    debug: true,             // Enable console logging
    use_standalone: true,    // Failover to Mock API if no LMS found
    compression: true,       // Compress suspend_data (lz-string)
    exit_type: "suspend"     // Default exit behavior
});

// 2. Connect — initSCO() = initialize() + start():
//    learner info, entry/mode, and suspend-data restore in one call.
if (scobot.initSCO() === 'true') {
    console.log(`Connected. Mode: ${scobot.getMode()}, Entry: ${scobot.getEntry() || 'ab-initio'}`);
}

// 3. Declare totals once — SCOBot manages cmi.progress_measure for you
//    as objectives complete, and gradeIt() gates completion on it.
scobot.setTotals({
    totalInteractions: '3',
    totalObjectives: '3',
    scoreMin: '0',
    scoreMax: '100'
});

// 4. Bookmark + per-page state — no hand-rolled suspend_data blobs.
scobot.setBookmark('page_5');
scobot.setSuspendDataByPageID('page_5', 'Quiz Page', { answered: true, choice: 'b' });
// ...on relaunch: scobot.getBookmark() / scobot.getSuspendDataByPageID('page_5')

// 5. Record a question — the interaction AND its per-question objective.
scobot.setInteraction({
    id: 'q1',
    type: 'choice',              // true-false, choice, matching, fill-in, performance...
    learner_response: ['b'],     // SCOBot handles the SCORM encoding
    result: 'correct',
    weighting: '1',              // note: write key is 'weighting'; getInteraction returns it as 'weight'
    timestamp: new Date().toISOString(),
    latency: 'PT12S'
});
scobot.setObjective({
    id: 'q1',
    score: { scaled: '1', raw: '1', min: '0', max: '1' },
    success_status: 'passed',
    completion_status: 'completed',
    progress_measure: '1',
    description: 'Question 1'
});
// ...read back any time: scobot.getInteraction('q1') / scobot.getObjective('q1')

// 6. Grade & exit — gradeIt() derives score.scaled + success_status and
//    gates completion_status; finish() ends the attempt (or suspend() to
//    save-and-resume). Both commit and terminate for you.
scobot.setvalue('cmi.score.raw', '90');  // gradeIt's input (min/max via setTotals)
scobot.gradeIt();
scobot.finish();

Raw CMI access — scobot.setvalue('cmi.location', 'slide_5') / getvalue(...) remain available for anything the Content API doesn't wrap, with automatic SCORM 1.2 ↔ 2004 syntax bridging.
