@storysdk/types v2.0.1

@storysdk/types

TypeScript definitions and interfaces for StorySDK. This package provides shared type definitions used across all StorySDK packages, ensuring type safety and consistency.

Installation

npm install @storysdk/types

Overview

This package contains TypeScript definitions for:

• Common data structures (colors, fonts, backgrounds, etc.)
• Widget type definitions (text, image, video, quiz widgets, etc.)
• Story and group structures
• UI element types (buttons, icons, animations)

Basic Usage

import { 
  GroupType, 
  WidgetType, 
  MaterialIconValueType,
  BackgroundType,
  ColorValue
} from '@storysdk/types';

// Define a custom group
const myGroup: GroupType = {
  id: 'custom-group',
  name: 'My Custom Group',
  // ... other properties
};

// Type-safe widget configuration
const textWidget: TextWidgetParamsType = {
  text: 'Hello World',
  fontParams: {
    fontSize: 16,
    fontWeight: 'bold'
  }
};

Type Categories

Common Types (common/)

Core data types used throughout the SDK:

• MaterialIconValueType - Enumeration of supported Material Design icons
• BackgroundType - Background configuration (color, gradient, image)
• BorderType - Border styling properties
• ColorValue - Color representation (hex, rgba, named colors)
• FontParamsType - Typography configuration
• VideoMetadataType - Video file metadata and properties
• QuizAnswersScoreParams - Quiz scoring and answer validation
• EmojiItemType - Emoji data structure

Widget Types (widgets/)

Type definitions for all supported widget types:

• TextWidgetParamsType - Text content and styling
• ImageWidgetParamsType - Image display and positioning
• VideoWidgetParamsType - Video playback and controls
• RectangleWidgetParamsType - Shape and container widgets
• QuizWidgetParamsType - Interactive quiz elements
• EmojiWidgetParamsType - Emoji reaction widgets
• IconWidgetParamsType - Icon display and styling
• WidgetType - Base widget interface

Group and Story Types

High-level structure definitions:

• GroupType - Story group configuration and metadata
• StoryContext - Runtime story state and context
• GroupsListProps - Props for rendering story groups

Advanced Usage

Custom Widget Development

import { WidgetType, WidgetParamsType } from '@storysdk/types';

// Define custom widget parameters
interface CustomWidgetParams extends WidgetParamsType {
  customProperty: string;
  customConfig: {
    enabled: boolean;
    value: number;
  };
}

// Use in widget implementation
const customWidget: WidgetType<CustomWidgetParams> = {
  type: 'custom',
  params: {
    customProperty: 'value',
    customConfig: {
      enabled: true,
      value: 42
    }
  }
};

Type Guards and Validation

import { WidgetType } from '@storysdk/types';

function isTextWidget(widget: WidgetType): widget is WidgetType<TextWidgetParamsType> {
  return widget.type === 'text';
}

// Usage
if (isTextWidget(someWidget)) {
  // TypeScript now knows this is a text widget
  console.log(someWidget.params.text);
}

Contributing

When adding new types:

1. Place common types in common/
2. Widget-specific types go in widgets/
3. Export new types from index.ts
4. Add JSDoc comments for complex types
5. Ensure backward compatibility

Version Compatibility

• v1.6.x: Compatible with StorySDK Core 1.9.x and React 1.9.x
• Follows semantic versioning for type additions and changes
• Breaking changes will increment major version
