# Abacus-React Feature Enhancement Plan
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The web application has developed numerous custom patterns and workarounds for styling, layout, and interactions with the abacus component. These patterns reveal gaps in the abacus-react API that, if addressed, would significantly improve developer experience and reduce code duplication across the application.
|
||||
|
||||
## Priority 1: Critical Features (High Impact, High Frequency)
|
||||
|
||||
### 1. **Inline "Mini Abacus" Component**
|
||||
**Location**: `apps/web/src/app/arcade/complement-race/components/AbacusTarget.tsx`
|
||||
|
||||
**Current Implementation**:
|
||||
```tsx
|
||||
<AbacusReact
|
||||
value={number}
|
||||
columns={1}
|
||||
interactive={false}
|
||||
showNumbers={false}
|
||||
hideInactiveBeads={true}
|
||||
scaleFactor={0.72}
|
||||
customStyles={{
|
||||
columnPosts: { opacity: 0 },
|
||||
}}
|
||||
/>
|
||||
```
|
||||
|
||||
**Problem**: Creating an inline mini-abacus for displaying single digits requires multiple props and style overrides. This pattern appears throughout game UIs.
|
||||
|
||||
**Proposed Solution**: Add a `variant` prop with preset configurations:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
<AbacusReact
|
||||
value={7}
|
||||
variant="inline-digit"
|
||||
// Automatically sets: columns=1, hideInactiveBeads, transparent frame, optimal scaleFactor
|
||||
/>
|
||||
|
||||
// Or more granular:
|
||||
<AbacusReact
|
||||
value={7}
|
||||
compact={true} // Removes frame, optimizes spacing
|
||||
frameVisible={false} // Hide posts and bar
|
||||
/>
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Single prop instead of 5+
|
||||
- Consistent inline abacus appearance across the app
|
||||
- Better semantic intent
|
||||
|
||||
---
|
||||
|
||||
### 2. **Theme-Aware Styling Presets**
|
||||
**Locations**:
|
||||
- `MyAbacus.tsx` (lines 60-85) - structural & trophy styles
|
||||
- `HeroAbacus.tsx` (lines 20-32) - structural styles
|
||||
- `LevelSliderDisplay.tsx` (lines 263-275) - dark theme styles
|
||||
|
||||
**Current Pattern**: Every component defines custom style objects for structural elements:
|
||||
|
||||
```tsx
|
||||
const structuralStyles = {
|
||||
columnPosts: {
|
||||
fill: 'rgb(255, 255, 255)',
|
||||
stroke: 'rgb(200, 200, 200)',
|
||||
strokeWidth: 2,
|
||||
},
|
||||
reckoningBar: {
|
||||
fill: 'rgb(255, 255, 255)',
|
||||
stroke: 'rgb(200, 200, 200)',
|
||||
strokeWidth: 3,
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
**Problem**: Manual style object creation for common themes is repetitive and error-prone.
|
||||
|
||||
**Proposed Solution**: Add theme presets to abacus-react:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
<AbacusReact
|
||||
value={123}
|
||||
theme="dark" // or "light", "translucent", "solid", "trophy"
|
||||
/>
|
||||
|
||||
// Or expose theme constants
|
||||
import { ABACUS_THEMES } from '@soroban/abacus-react'
|
||||
<AbacusReact customStyles={ABACUS_THEMES.dark} />
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Eliminates ~30 lines of style definitions per component
|
||||
- Ensures visual consistency
|
||||
- Makes theme switching trivial
|
||||
|
||||
---
|
||||
|
||||
### 3. **Scaling Containers & Responsive Layouts**
|
||||
**Locations**:
|
||||
- `HeroAbacus.tsx` (lines 133-138) - manual scale transforms
|
||||
- `MyAbacus.tsx` (lines 214-218) - responsive scale values
|
||||
- `LevelSliderDisplay.tsx` (lines 370-379) - dynamic scale calculation
|
||||
|
||||
**Current Pattern**: Components manually wrap abacus in transform containers:
|
||||
|
||||
```tsx
|
||||
<div style={{
|
||||
transform: 'scale(3.5)',
|
||||
transformOrigin: 'center center'
|
||||
}}>
|
||||
<AbacusReact value={1234} columns={4} />
|
||||
</div>
|
||||
```
|
||||
|
||||
**Problem**: Manual transform handling requires extra DOM nesting, breaks click boundaries, and makes centering complex.
|
||||
|
||||
**Proposed Solution**: Enhanced `scaleFactor` with responsive breakpoints:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
<AbacusReact
|
||||
value={1234}
|
||||
scaleFactor={{ base: 2.5, md: 3.5, lg: 4.5 }} // Responsive
|
||||
scaleOrigin="center" // Handle transform origin
|
||||
scaleContainer={true} // Apply correct boundaries for interaction
|
||||
/>
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Eliminates wrapper divs
|
||||
- Proper click/hover boundaries
|
||||
- Built-in responsive scaling
|
||||
|
||||
---
|
||||
|
||||
## Priority 2: Developer Experience Improvements
|
||||
|
||||
### 4. **Bead Diff Calculation System**
|
||||
**Location**: `apps/web/src/utils/beadDiff.ts` (285 lines) + `abacusInstructionGenerator.ts` (400+ lines)
|
||||
|
||||
**Current Implementation**: Complex utilities to calculate which beads need to move between states:
|
||||
|
||||
```tsx
|
||||
// Current external pattern
|
||||
import { calculateBeadDiffFromValues } from '@/utils/beadDiff'
|
||||
|
||||
const diff = calculateBeadDiffFromValues(fromValue, toValue)
|
||||
const stepBeadHighlights = diff.changes.map(change => ({
|
||||
placeValue: change.placeValue,
|
||||
beadType: change.beadType,
|
||||
direction: change.direction,
|
||||
// ...
|
||||
}))
|
||||
```
|
||||
|
||||
**Problem**: Tutorial/game developers need to calculate bead movements manually. This core logic belongs in abacus-react.
|
||||
|
||||
**Proposed Solution**: Add a diff calculation hook:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
import { useAbacusDiff } from '@soroban/abacus-react'
|
||||
|
||||
function Tutorial() {
|
||||
const diff = useAbacusDiff(startValue, targetValue)
|
||||
|
||||
return (
|
||||
<AbacusReact
|
||||
value={currentValue}
|
||||
stepBeadHighlights={diff.highlights} // Generated by hook
|
||||
// diff also includes: instructions, order, validation
|
||||
/>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Centralizes "diff" algorithm
|
||||
- Eliminates ~500 lines of application code
|
||||
- Better tested and maintained
|
||||
|
||||
---
|
||||
|
||||
### 5. **Tutorial/Step Context Provider**
|
||||
**Location**: `apps/web/src/components/tutorial/TutorialContext.tsx`
|
||||
|
||||
**Current Pattern**: Apps need to implement complex state management for multi-step tutorial flows with reducer patterns, event tracking, and error handling.
|
||||
|
||||
**Problem**: Tutorial infrastructure is duplicated across components. The logic for tracking progress through abacus instruction steps is tightly coupled to application code.
|
||||
|
||||
**Proposed Solution**: Add optional tutorial/stepper context to abacus-react:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
import { AbacusReact, AbacusTutorial } from '@soroban/abacus-react'
|
||||
|
||||
<AbacusTutorial
|
||||
steps={[
|
||||
{ from: 0, to: 5, instruction: "Add 5" },
|
||||
{ from: 5, to: 15, instruction: "Add 10" },
|
||||
]}
|
||||
onStepComplete={(step) => { /* analytics */ }}
|
||||
onComplete={() => { /* celebration */ }}
|
||||
>
|
||||
<AbacusReact />
|
||||
</AbacusTutorial>
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Reusable tutorial infrastructure
|
||||
- Built-in progress tracking and validation
|
||||
- Could power educational features across projects
|
||||
|
||||
---
|
||||
|
||||
## Priority 3: Nice-to-Have Enhancements
|
||||
|
||||
### 6. **Animation Speed Configuration**
|
||||
**Location**: `LevelSliderDisplay.tsx` (lines 306-345)
|
||||
|
||||
**Current Pattern**: Applications control animation speed by rapidly changing the value prop:
|
||||
|
||||
```tsx
|
||||
const intervalMs = 500 - danProgress * 490 // 500ms down to 10ms
|
||||
setInterval(() => {
|
||||
setAnimatedDigits(prev => {
|
||||
// Rapidly change digits to simulate calculation
|
||||
})
|
||||
}, intervalMs)
|
||||
```
|
||||
|
||||
**Problem**: "Rapid calculation" animation requires external interval management.
|
||||
|
||||
**Proposed Solution**: Add animation speed prop:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
<AbacusReact
|
||||
value={calculatingValue}
|
||||
animationSpeed="fast" // or "normal", "slow", or ms number
|
||||
autoAnimate={true} // Animate value prop changes automatically
|
||||
/>
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- Smoother animations with internal management
|
||||
- Consistent timing across the app
|
||||
|
||||
---
|
||||
|
||||
### 7. **Draggable/Positionable Abacus Cards**
|
||||
**Location**: `InteractiveFlashcards.tsx`
|
||||
|
||||
**Current Pattern**: Complex drag-and-drop implementation wrapped around each AbacusReact instance with pointer capture, offset tracking, and rotation.
|
||||
|
||||
**Problem**: Making abacus instances draggable requires significant boilerplate.
|
||||
|
||||
**Proposed Solution**: This is probably too specific to remain external. However, a ref-based API to get bounding boxes would help:
|
||||
|
||||
```tsx
|
||||
// Possible improvement
|
||||
const abacusRef = useAbacusRef()
|
||||
|
||||
<AbacusReact ref={abacusRef} />
|
||||
|
||||
// abacusRef.current.getBoundingBox() for drag calculations
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 8. **Column Highlighting for Multi-Step Problems**
|
||||
**Location**: Tutorial system extensively
|
||||
|
||||
**Current Pattern**: Manual column highlighting based on place values with custom overlay positioning logic.
|
||||
|
||||
**Problem**: Highlighting specific columns (e.g., "the tens column") requires external overlay management.
|
||||
|
||||
**Proposed Solution**: Add native column highlighting:
|
||||
|
||||
```tsx
|
||||
// Native API proposal
|
||||
<AbacusReact
|
||||
value={123}
|
||||
highlightColumns={[1]} // Highlight tens column
|
||||
columnLabels={["ones", "tens", "hundreds"]} // Optional labels
|
||||
/>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Priority 4: Documentation & Exports
|
||||
|
||||
### 9. **Utility Functions & Types**
|
||||
**Current State**: Apps re-implement utilities for working with abacus states:
|
||||
- `numberToAbacusState()` - convert numbers to bead states
|
||||
- `calculateBeadChanges()` - diff algorithm
|
||||
- `ValidPlaceValues` type - imported but limited
|
||||
|
||||
**Proposed Solution**: Export more utilities from abacus-react:
|
||||
|
||||
```tsx
|
||||
// Expanded exports
|
||||
export {
|
||||
// Utilities
|
||||
numberToAbacusState,
|
||||
abacusStateToNumber,
|
||||
calculateBeadDiff,
|
||||
validateAbacusValue,
|
||||
|
||||
// Types
|
||||
AbacusState,
|
||||
BeadState,
|
||||
PlaceValue,
|
||||
|
||||
// Hooks
|
||||
useAbacusDiff,
|
||||
useAbacusValidation,
|
||||
useAbacusState,
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Questions for Discussion
|
||||
|
||||
1. Should we split these into separate packages (e.g., `@soroban/abacus-tutorial`)?
|
||||
2. Which theme presets should be included by default?
|
||||
3. Should responsive scaling use CSS media queries or JS breakpoints?
|
||||
4. How much tutorial logic belongs in the core library vs. app code?

### Theme Presets
|
||||
|
||||
Use pre-defined themes for quick styling:
|
||||
|
||||
```tsx
|
||||
import { AbacusReact, ABACUS_THEMES } from '@soroban/abacus-react';
|
||||
|
||||
// Available themes: 'light', 'dark', 'trophy', 'translucent', 'solid', 'traditional'
|
||||
<AbacusReact
|
||||
value={123}
|
||||
columns={3}
|
||||
customStyles={ABACUS_THEMES.dark}
|
||||
/>
|
||||
|
||||
<AbacusReact
|
||||
value={456}
|
||||
columns={3}
|
||||
customStyles={ABACUS_THEMES.trophy} // Golden frame for achievements
|
||||
/>
|
||||
|
||||
<AbacusReact
|
||||
value={789}
|
||||
columns={3}
|
||||
customStyles={ABACUS_THEMES.traditional} // Brown wooden appearance
|
||||
/>
|
||||
```
|
||||
|
||||
**Available Themes:**
|
||||
- `light` - Solid white frame with subtle gray accents (best for light backgrounds)
|
||||
- `dark` - Translucent white with subtle glow (best for dark backgrounds)
|
||||
- `trophy` - Golden frame with warm tones (best for achievements/rewards)
|
||||
- `translucent` - Nearly invisible frame (best for inline/minimal UI)
|
||||
- `solid` - Black frame (best for high contrast/educational contexts)
|
||||
- `traditional` - Brown wooden appearance (best for traditional soroban aesthetic)
|
||||
|
||||
### Compact/Inline Display
|
||||
|
||||
Create mini abacus displays for inline use:
|
||||
|
||||
```tsx
|
||||
// Compact mode - automatically hides frame and optimizes spacing
|
||||
<AbacusReact
|
||||
value={7}
|
||||
columns={1}
|
||||
compact={true}
|
||||
hideInactiveBeads={true}
|
||||
scaleFactor={0.7}
|
||||
/>
|
||||
|
||||
// Or manually control frame visibility
|
||||
<AbacusReact
|
||||
value={42}
|
||||
columns={2}
|
||||
frameVisible={false} // Hide column posts and reckoning bar
|
||||
/>
|
||||
```

||||
**Column Highlighting:**
|
||||
- `highlightColumns` - Array of column indices to highlight (e.g., `[0, 2]` highlights first and third columns)
|
||||
- `columnLabels` - Optional labels displayed above each column (indexed left to right)

|
||||
|
||||
```tsx
|
||||
import { useAbacusDiff } from '@soroban/abacus-react';
|
||||
|
||||
function Tutorial() {
|
||||
const [currentValue, setCurrentValue] = useState(5);
|
||||
const targetValue = 15;
|
||||
|
||||
// Get diff information: which beads need to move
|
||||
const diff = useAbacusDiff(currentValue, targetValue);
|
||||
|
||||
return (
|
||||
<div>
|
||||
<p>{diff.summary}</p> {/* "add heaven bead in tens column, then..." */}
|
||||
<AbacusReact
|
||||
value={currentValue}
|
||||
stepBeadHighlights={diff.highlights} // Highlight beads that need to change
|
||||

|
||||
// Check bead positions
|
||||
const onesHasHeaven = state[0].heavenActive; // false (3 < 5)
|
||||
const tensEarthCount = state[1].earthActive; // 2 (20 = 2 tens)

||||
|
||||
return <div>Ones column heaven bead: {onesHasHeaven ? 'active' : 'inactive'}</div>;
