März 2026) + +**Analyst:** GitHub Copilot (Claude Opus 4.6) +**Kontext:** Nach umfangreicher Sanierung (Issues ~1.400 → 891) soll ein priorisierter Refactoring-Plan für die verbleibenden Cognitive Complexity- und Typunsicherheits-Issues erstellt werden. + +--- + +## 1. Strukturelle Diagnose: Zentren der Komplexität + +### 🔥 A: Die 428-LOC `useEffect`-Bombe in `arduino-board.tsx` +- **Problem:** Ein einziger `useEffect` (L264–L691) führt einen 10ms-Polling-Loop aus, der imperativ DOM-Elemente verändert. +- **Folge:** Extrem hohe Cognitive Complexity, hoher Wartungsaufwand, schwer testbar. + +### 🔥 B: Callback-Kaskaden in `execution-manager.ts` +- Hauptprobleme: `runSketch()` (114 LOC) und `setupLocalHandlers()` (98 LOC) enthalten mehrere verschachtelte Callback-Ketten (`PinStateBatcher`, `SerialOutputBatcher`, `onStdout/onStderr/onClose`). +- Resultat: viele Sonar-Complexity-Flags und schwer nachverfolgbare Prozesszustände. + +### 🔥 C: Mikro-Patterns, die Sonar-Issues multiplizieren +- `arr[arr.length-1]` statt `.at(-1)` +- `window` statt `globalThis` +- `substr()` statt `substring()` +- redundante Union-Typen statt Typalias +- nicht `readonly` markierte Member +- Nested template literals + +Diese Muster erzeugen viele (~40) leicht fixbare Issues. + +--- + +## 2. Low-Hanging Fruit (Prio A) + +### ✅ A1: ESLint-Autofixes (0 Risiko) +Aktiviere/verschärfe Regeln in `eslint.config.js` und führe `npx eslint --fix .` aus: +- `unicorn/prefer-at`: `arr[arr.length-1]` → `arr.at(-1)` +- `unicorn/prefer-global-this`: `window` → `globalThis` +- `unicorn/prefer-string-slice`: `substr` → `substring` / `slice` +- `unicorn/prefer-node-protocol`: `fs` → `node:fs` (beliebte Imports) +- `sonarjs/no-nested-ternary`: zerlege verschachtelte Ternares in Klartext +- `@typescript-eslint/prefer-readonly`: `readonly`-Member + +### ✅ A2: Shared Helper für `pinMode` (4 Issues) +Extrahiere `pinModeToString(mode: number)` und ersetze alle nested ternaries in: +- `output-panel.tsx` (2x) +- `registry-manager.ts` +- `simulation.ws.ts` + +### ✅ A3: `console.*` → `Logger` (6–9 Issues) +- `use-compile-and-run.ts` (`console.info`) → `Logger.info` +- `simulation.ws.ts` (`console.info`) → `Logger.info` +- `arduino-board.tsx` debug `console.log` → entfernen / `Logger.debug` + +### ✅ A4: `String.raw` für C++-Template (1 Issue) +- `arduino-string.ts`: `String.raw` statt normalem Template, damit Backslashes korrekt bleiben. + +**Ergebnis:** ~50 Issues sofort raus, Baseline sauber. + +--- + +## 3. Architektonische Operationen (Prio B) + +### 💥 B1: `arduino-board.tsx` zerschlagen (Key-Op) +**Ziel:** Reduzierung von LOC + Cognitive Complexity, solide API für UI/DOM-Logik. + +#### B1.1 → `usePinPollingEngine()` (428 LOC → Hook) +- Extrahiere den 10ms-Polling-Loop vollständig. +- Zerlege ihn in 4 Sub-Runner: `updateDigitalPins()`, `updateAnalogPins()`, `updateLEDs()`, `updateLabels()`. +- Resultat: `ArduinoBoard` verliert ~40% seines Codes; `performAllUpdates` wird testbar. + +#### B1.2 → `useAnalogSliders()` (93 LOC) +- Entferne Slider-Position- und Value-Sync-Logik aus `ArduinoBoard`. +- Hook liefert `sliderPositions` und `sliderValues`. + +#### B1.3 → `useBoardScale()` (60 LOC) +- ResizeObserver + `getModifiedSvg`/`getOverlaySvg` werden ein eigener Hook. + +#### B1.4 → `AnalogPinDialog` in eigene Datei +- Auskapselung von Positionierungs-Logik (3× `getComputedStyle`) und State. + +**Impact:** `arduino-board.tsx` wird ~460 LOC und ~15–20 CC, plus klar definierte Hooks. + +--- + +## 4. Typ-Härtung (Prio C) + +### C1: Schnelle Typfixes (5 Stellen) +- `arduino-compiler.ts` → `IOPinRecord[]` +- `use-debug-console.ts` / `use-pin-state.ts` → `CustomEvent<{value: boolean}>` +- `shared/logger.ts` → `reason: unknown` +- `compiler.routes.ts` → `headers?: Array<{name: string; content: string}>` + +### C2: `any` → Node-Types (3 Stellen) +- `process-executor.ts`: `ChildProcess` statt `any` + global augmentation für `spawnInstances` +- `run-sketch-types.ts`: `TelemetryMetrics` statt any, aligned mit `execution-manager.ts` + +### C3: `ParsedLine` Discriminated Union (1 Stelle, hoher Hebel) +- `stream-handler.ts` `handleParsedLine(parsed: any, ...)` → `ParsedLine`-Union (Registry, PinState, SerialOutput, etc.) +- Ergebnis: Compiler erzwingt Exhaustiveness, `any` verschwindet + Code lesbar. + +### C4: `as`-Casts in `arduino-board.tsx` (8 Stellen) +- Alle `as EventListener` usw. entfernen via `onCustomEvent(target, name, handler)` Utility. + +--- + +## 5. Risiko-Einschätzung (wo brennt es am meisten?) + +### 🔥 Höchstes Regressions-Risiko +1. **B1 (`usePinPollingEngine`)** – Polling-Loop manipuliert DOM direkt, kann raceconditions erzeugen. *Test-Absicherung erforderlich!* (E2E + Visual / Snapshot) +2. **Stream/Parser-Refactoring** (`stream-handler.ts`) – Core-Pipeline für Pin-/Serial-State. Fehler hier schlägt in vielen Szenarien durch. + +### ⚠️ Mittleres Risiko +- `execution-manager.ts` Dekomposition (siehe oben) – wenn Handler-Reihenfolge nicht 1:1 bleibt, kann Simulation state-locken. +- `registry-manager.ts` `updatePinMode()` (CC=29) – hier wird Konfliktlogik gepflegt. + +### ✅ Niedrigstes Risiko +- ESLint-Autofixes + `console.*` → `Logger` + `pinModeToString` Helper + `readonly`-Fixes: keine Logikveränderung. + +--- + +## 6. Nächste Schritte (empfohlene Abfolge) + +1. **Sofort:** Regelset erweitern + `npx eslint --fix .` → Baseline sichern. +2. **Parallel:** `pinModeToString()`-Helper + `console.*` → `Logger` + `String.raw` fixen. +3. **Big Move:** `arduino-board.tsx` in 4 Module (`usePinPollingEngine`, `useAnalogSliders`, `useBoardScale`, `AnalogPinDialog`) zerschneiden (+ Tests). +4. **Typen:** `any`-Stellen aus C1/C2 angehen, dann `ParsedLine`-Union einführen. +5. **Als letztes:** `execution-manager.ts` und `registry-manager.ts` strukturieren (Modul-Extraktion, kleinere private helpers). + +--- + +## 7. Quick-Win-Priorität (Auswahl) + +1. **Prio A:** ESLint-Regeln + `eslint --fix` (Schnellster Impact, niedrigstes Risiko) +2. **Prio B:** `arduino-board.tsx` Polling-Hook (größter Komplexitätshebel) +3. **Prio C:** `any` → typed Event/ParsedLine (Weniger Fehler & bessere Code-Qualität) + +--- + +### Hinweis +Die Analyse beruht auf der aktuellen Codebasis (Stand 16. März 2026). Nach Abschluss der Prio-A-Patches sollten wir erneut die Sonar/Metrics-Liste laufen lassen, um die tatsächliche Issue-Reduktion zu verifizieren und ggf. den nächsten “multiplikativen” Hotspot zu bestimmen. diff --git a/REFACTORING_ANALYSIS.md b/REFACTORING_ANALYSIS.md new file mode 100644 index 00000000..8cb076fd --- /dev/null +++ b/REFACTORING_ANALYSIS.md @@ -0,0 +1,415 @@ +# ArduinoSimulatorPage Refactoring Analysis + +**Current File Size:** 1510 lines +**Goal:** Extract large code blocks into sub-components to improve maintainability + +--- + +## 1.
