State Overview
WikiOnitViewer maintains the simplest state model among all wiki viewers: just one custom array plus inherited properties from the base class.┌─────────────────────────────────────────────────────┐
│ State Inventory │
├─────────────────────────────────────────────────────┤
│ │
│ Own State: │
│ sessions: OnitSession[] │
│ │
│ Inherited State (from WikiBaseViewer): │
│ container: HTMLElement | null │
│ projectSlug: string │
│ category: string │
│ isWip: boolean │
│ settings: WikiViewerSettings │
│ currentDocument: string │
│ │
│ Total: 7 properties (6 inherited + 1 own) │
│ │
└─────────────────────────────────────────────────────┘
Sessions Array
The only state property unique to OnIt:┌───────────────────────────────────────────────────────────────────────┐
│ SESSIONS ARRAY │
├───────────────────────────────────────────────────────────────────────┤
│ │
│ DECLARATION: │
│ private sessions: OnitSession[] = [] │
│ │
│ CHARACTERISTICS: │
│ ├── Array of parsed session objects │
│ ├── Sorted newest first (descending sortKey) │
│ ├── Populated during loadSessions() │
│ └── Completely replaced on refresh() │
│ │
└───────────────────────────────────────────────────────────────────────┘
┌───────────────────────────────────────────────────────────────────────┐
│ sessions[0] = { │
│ │
│ path: "/full/path/2025-12-28-14-30-session.md" │
│ name: "2025-12-28-14-30-session.md" │
│ date: "2025-12-28" │
│ time: "14:30" │

State Lifecycle
Initialization
┌─────────────────────────────────────────────────────┐
│ Initialization State Changes │
├─────────────────────────────────────────────────────┤
│ │
│ BEFORE init(): │
│ container: null │
│ sessions: [] │
│ isWip: true (default) │
│ │
│ ↓ init(container, projectSlug, "onit") │
│ │
│ AFTER init(): │
│ container: HTMLElement (assigned) │
│ sessions: [OnitSession, ...] │
│ isWip: true (unchanged) │
│ category: "onit" │
│ settings: loaded from localStorage │
│ │
└─────────────────────────────────────────────────────┘
Toggle Transition
┌─────────────────────────────────────────────────────┐
│ WIP/Wiki Toggle Effect │
├─────────────────────────────────────────────────────┤
│ │
│ WIP Mode: │
│ isWip: true │
│ sessions: [WIP sessions from wip/onit/] │
│ │
│ ↓ User clicks [Wiki] button │
│ │
│ Wiki Mode: │
│ isWip: false │
│ sessions: [Wiki sessions from wiki/onit/] │
│ │
│ Note: Other properties unchanged │
│ │
└─────────────────────────────────────────────────────┘
Refresh Cycle
┌─────────────────────────────────────────────────────┐
│ Refresh State Changes │
├─────────────────────────────────────────────────────┤
│ │
│ BEFORE refresh(): │
│ sessions: [old data - may be stale] │
│ │
│ ↓ refresh() called │
│ │
│ AFTER refresh(): │
│ sessions: [new data - fresh from filesystem] │
│ │
│ Note: Complete array replacement │
│ DOM fully re-rendered │
│ Accordion states LOST │
│ │
└─────────────────────────────────────────────────────┘
State Dependencies
Path construction depends on three state properties:┌───────────────────────────────────────────────────────────────────────┐
│ PATH CALCULATION (getBasePath) │
├───────────────────────────────────────────────────────────────────────┤
│ │
│ BASE = "~/Library/Application Support/monolex/protocols/niia/work" │
│ │
│ FORMULA: │
│ folder = isWip ? "wip" : "wiki" │
│ path = "{base}/{projectSlug}/{folder}/{category}" │
│ │
│ EXAMPLE: │
│ projectSlug = "monolex-006" │
│ isWip = true │
│ category = "onit" │
│ │
│ Result: ~/Library/.../work/monolex-006/wip/onit/ │
│ │
│ Changing ANY dependency changes the filesystem path │
│ and thus the loaded sessions. │
│ │
└───────────────────────────────────────────────────────────────────────┘
Unidirectional Data Flow
State flows in one direction only:┌─────────────────────────────────────────────────────┐
│ Data Flow │
├─────────────────────────────────────────────────────┤
│ │
│ User Action (click toggle/refresh) │
│ ↓ │
│ Event Handler │
│ ↓ │
│ State Update (isWip, sessions) │
│ ↓ │
│ Re-render (render() called) │
│ ↓ │
│ DOM Updated (content replaced) │
│ ↓ │
│ Event Listeners Attached (to new elements) │
│ ↓ │
│ (Loop back to User Action) │
│ │
│ No reverse flow: DOM → State │
│ │
└─────────────────────────────────────────────────────┘
DOM vs JavaScript State
Clear separation between persistent state and ephemeral UI state: JavaScript State (this.*):sessions: OnitSession[] (source of truth)isWip: booleansettings: ViewerSettings- Persists across renders
- Accordion expanded/collapsed
- Content loaded (
data-loaded) - Arrow rotation
- Scroll position
- Lost on re-render
- JS state is source of truth for data
- DOM state is ephemeral (recreated on render)
- Re-render regenerates DOM from JS state
- No two-way binding
State Reset Pattern
Complete replacement on refresh:┌───────────────────────────────────────────────────────────────────────┐
│ REFRESH PATTERN │
├───────────────────────────────────────────────────────────────────────┤
│ │
│ refresh() │
│ │ │
│ ├── await this.loadSessions() ← REPLACES this.sessions │
│ │ │
│ └── this.render() ← Re-renders entire DOM │
│ │
│ EFFECT: │
│ ├── No incremental updates │
│ ├── No diffing/patching │
│ ├── Guaranteed consistency │
│ └── Accordion states lost │
│ │
│ TRADE-OFFS: │
│ ├── Simplicity (SMPC principle) │
│ ├── Easy to reason about │
│ ├── Potential performance impact on large lists │
│ └── Loses UI state │
│ │
└───────────────────────────────────────────────────────────────────────┘
Memory Management
Automatic cleanup via garbage collection: On refresh():this.sessions = new array→ Old array becomes unreachable- Container content replaced → Old DOM nodes removed
- JavaScript GC cleans up old arrays
- Browser GC cleans up old DOM nodes
- Event listeners on old nodes auto-removed
Settings Management
User preferences loaded from localStorage:┌───────────────────────────────────────────────────────────────────────┐
│ WIKI VIEWER SETTINGS │
├───────────────────────────────────────────────────────────────────────┤
│ │
│ INTERFACE: │
│ ┌───────────────────────────────────────────────────────────────┐ │
│ │ fontSize: string // "12" │ │
│ │ fontWeight: string // "300" │ │
│ │ lineHeight: string // "1.6" │ │
│ │ opacity: string // "75" │ │
│ │ fontFamily: string // "CodexMono, CodexMono EA" │ │
│ └───────────────────────────────────────────────────────────────┘ │
│ │
│ LOADING: │
│ For each setting: │
│ value = localStorage.getItem("wikiViewer{Setting}") || default │
│ │
│ DEFAULTS: │
│ fontSize = "12" │
│ fontWeight = "300" │
│ lineHeight = "1.6" │
│ opacity = "75" │
│ fontFamily = "CodexMono, CodexMono EA" │
│ │
│ Settings apply to entire viewer container via getViewerStyles() │
