react-native-scorm-player

react-native-scorm-player is a React Native library for integrating SCORM-compliant e-learning content into your mobile applications. It provides a WebView-based SCORM player with support for SCORM 1.1, SCORM 1.2, and SCORM 2004 standards.

Features

• SCORM 1.1, SCORM 1.2, and SCORM 2004 support
• WebView-based SCORM player
• Handles SCORM API calls (LMSInitialize, LMSFinish, LMSGetValue, LMSSetValue, etc.)
• Injects SCORM JavaScript bridge for seamless communication
• Supports both local and remote SCORM packages

Installation

Install the package using npm or yarn:

npm install react-native-scorm-player

or

yarn add react-native-scorm-player

Usage

Here is an example of how to use the ScormPlayer component:

import React, { useRef } from "react";
import { View } from "react-native";
import ScormPlayer, { SCORMDataModel, API } from "react-native-scorm-player";
import WebView from "react-native-webview";

const App = () => {
  const webViewRef = useRef<WebView | null>(null);

  const scormAPI: API = {
    LMSInitialize: () => console.log("LMSInitialize called"),
    LMSFinish: () => console.log("LMSFinish called"),
    LMSGetValue: (parameter) =>
      console.log("LMSGetValue called with", parameter),
    LMSSetValue: (parameter, value) =>
      console.log("LMSSetValue called with", parameter, value),
    LMSCommit: () => console.log("LMSCommit called"),
    LMSGetLastError: () => console.log("LMSGetLastError called"),
    LMSGetErrorString: () => console.log("LMSGetErrorString called"),
    LMSGetDiagnostic: () => console.log("LMSGetDiagnostic called"),
  };

  const prevSCORMProgress: SCORMDataModel = {
    "cmi.core.student_id": "12345",
    "cmi.core.student_name": "John Doe",
  };

  return (
    <View style={{ flex: 1 }}>
      <ScormPlayer
        scormUrl="https://example.com/path-to-scorm-package"
        webViewRef={webViewRef}
        API={scormAPI}
        prevSCORMProgress={prevSCORMProgress}
      />
    </View>
  );
};

export default App;

API

ScormPlayer

Props

Prop	Type	Description
scormUrl	string	URL or path to the SCORM package
webViewRef	React.RefObject	Reference to the WebView instance
API	API	SCORM API implementation
prevSCORMProgress	SCORMDataModel	Previous SCORM progress data
...webViewProps	WebViewProps	Additional props for the WebView

API

The API interface defines the SCORM API methods:

• LMSInitialize: Initializes the SCORM session
• LMSFinish: Ends the SCORM session
• LMSGetValue: Retrieves a SCORM data model value
• LMSSetValue: Sets a SCORM data model value
• LMSCommit: Commits the SCORM data
• LMSGetLastError: Retrieves the last error code
• LMSGetErrorString: Retrieves the error string for a given error code
• LMSGetDiagnostic: Retrieves diagnostic information

Note on SCORM 2004 Methods

The API interface provided in this library is designed to support SCORM 1.2 and SCORM 2004. However, the method names in SCORM 2004 differ slightly from SCORM 1.2. For example, SCORM 2004 methods are as follows:

• Initialize("") : bool – Begins a communication session with the LMS.
• Terminate("") : bool – Ends a communication session with the LMS.
• GetValue(element : CMIElement) : string – Retrieves a value from the LMS.
• SetValue(element : CMIElement, value : string) : string – Saves a value to the LMS.
• Commit("") : bool – Indicates to the LMS that all data should be persisted (not required).
• GetLastError() : CMIErrorCode – Returns the error code that resulted from the last API call.
• GetErrorString(errorCode : CMIErrorCode) : string – Returns a short string describing the specified error code.
• GetDiagnostic(errorCode : CMIErrorCode) : string – Returns detailed information about the last error that occurred.

In this library, the SCORM 2004 methods are mapped to their SCORM 1.2 equivalents for simplicity. For example:

• Initialize is mapped to LMSInitialize
• Terminate is mapped to LMSFinish
• GetValue is mapped to LMSGetValue
• SetValue is mapped to LMSSetValue
• Commit is mapped to LMSCommit
• GetLastError is mapped to LMSGetLastError
• GetErrorString is mapped to LMSGetErrorString
• GetDiagnostic is mapped to LMSGetDiagnostic

This mapping ensures compatibility with both SCORM 1.2 and SCORM 2004, but users should be aware of these differences to avoid confusion.

SCORMDataModel

The SCORMDataModel interface defines the SCORM data model elements, such as cmi.core.student_id, cmi.core.lesson_status, and more.
