fix(biome-lint): resolve critical and medium priority lint issues
CRITICAL FIXES: - Fix noAsyncPromiseExecutor in xcoba.ts and xcoba2.ts * Removed async promise executor pattern * Refactored to proper promise chain with .then()/.catch() * Added proper error handling for unhandled rejections - Fix useIterableCallbackReturn in seed_berita.ts * Replaced forEach with for...of loop to avoid returning values in callbacks MEDIUM FIXES: - Fix useNodejsImportProtocol (728 files auto-fixed) * Updated Node.js builtin imports to use node: protocol * Files: eslint.config.mjs, vitest.config.ts, zgen/image.ts, and 725+ more - Fix useOptionalChain in xcoba.ts (auto-fixed) * Changed 'resOut && resOut.body' to 'resOut?.body' - Fix noImportantStyles in dark-mode-table.css * Added biome-ignore suppression comments with justification * Required to override Mantine UI library styles - Fix noUselessContinue in find-port.ts (auto-fixed) * Removed unnecessary continue statement - Fix useLiteralKeys (700+ files auto-fixed) * Simplified computed expressions to use literal keys * Example: obj['create'] -> obj.create RESULTS: - Errors reduced: 4,516 → 3,521 (-22%) - Warnings reduced: 3,861 → 2,083 (-46%) - Total issues reduced: 8,991 → 6,115 (-32%) - 735 files auto-fixed by biome lint --fix Remaining issues (~6,115): - Mostly noExplicitAny warnings requiring manual refactoring - Will be addressed in gradual code quality improvements Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

## 📂 Breakdown per Kategori
|
||||
|
||||
### 1. **Suspicious** (⚠️ Warnings + ❌ Errors)
|
||||
|
||||
#### `noExplicitAny` - ~3,500+ violations
|
||||
- **Severity:** ⚠️ Warning
|
||||
- **Impact:** Menonaktifkan banyak type checking rules
|
||||
- **Files affected:**
|
||||
- `__tests__/api/fileStorage.test.ts` (lines 10, 25)
|
||||
- `prisma/_seeder_list/desa/berita/seed_berita.ts` (line 85)
|
||||
- `zgen/image.ts` (line 29)
|
||||
- `prisma/lib/get_shared_images.ts` (lines 29, 53, 54)
|
||||
- Dan ~3,490+ files lainnya
|
||||
|
||||
**Rekomendasi:**
|
||||
- Gunakan type yang spesifik atau `unknown` dengan type guard
|
||||
- Prioritaskan fix di files yang sering digunakan
|
||||
|
||||
#### `noAsyncPromiseExecutor` - 2 violations ❌
|
||||
- **Files:**
|
||||
- `xcoba.ts:12` - `new Promise(async (resolve, reject) => {...})`
|
||||
- `xcoba2.ts:14` - `new Promise(async (resolve, reject) => {...})`
|
||||
|
||||
**Masalah:** Async promise executor bisa menyebabkan unhandled rejections
|
||||
|
||||
**Fix:**
|
||||
```typescript
|
||||
// ❌ Before
|
||||
return new Promise(async (resolve, reject) => {
|
||||
await someAsyncOperation();
|
||||
resolve(result);
|
||||
});
|
||||
|
||||
// ✅ After
|
||||
return new Promise(async (resolve, reject) => {
|
||||
try {
|
||||
await someAsyncOperation();
|
||||
resolve(result);
|
||||
} catch (error) {
|
||||
reject(error);
|
||||
}
|
||||
});
|
||||
```
|
||||
|
||||
#### `useIterableCallbackReturn` - 1 violation ❌
|
||||
- **File:** `prisma/_seeder_list/desa/berita/seed_berita.ts:34`
|
||||
|
||||
**Masalah:** forEach callback tidak seharusnya return value
|
||||
|
||||
**Fix:**
|
||||
```typescript
|
||||
// ❌ Before
|
||||
kategoriList.forEach((k) => validKategoriIds.add(k.id));
|
||||
|
||||
// ✅ After
|
||||
for (const k of kategoriList) {
|
||||
validKategoriIds.add(k.id);
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
**Fix:**
|
||||
```typescript
|
||||
// ❌ Before
|
||||
import fs from "fs";
|
||||
import path from "path";
|
||||
|
||||
// ✅ After
|
||||
import fs from "node:fs";

||||
import path from "node:path";
|
||||
```

9. **`noNonNullAssertion`** (~30+ warnings)
|
||||
- Gunakan optional chaining (`?.`) atau nullish coalescing (`??`)
|
||||

|
||||
## 📋 Configuration Issues
|
||||
|
||||
### `biome.json` - Deprecated Property
|
||||
```json
|
||||
{
|
||||
"files": {
|
||||
"experimentalScannerIgnores": [...] // ⚠️ DEPRECATED
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Rekomendasi:** Gunakan `files.includes` dengan negation pattern:
|
||||
```json
|
||||
{
|
||||
"files": {
|
||||
"includes": [
|
||||
"**/*",
|
||||
"!!**/node_modules",
|
||||
"!!**/.next",
|
||||
"!!**/out",
|
||||
"!!**/public"
|
||||
]
|
||||
}
|
||||
}
|
||||
```

|
||||
## 🎯 Action Plan
|
||||
|
||||
### Phase 1: Quick Wins (1-2 hours)
|
||||
```bash
|
||||
# 1. Auto-fix all fixable issues
|
||||
npx biome lint --fix .
|
||||
|
||||
# 2. Format code
|
||||
npx biome format --write .
|
||||
|
||||
# 3. Fix the 2 async promise executor errors manually
|
||||
# Files: xcoba.ts, xcoba2.ts
|
||||
```
|
||||
|
||||
### Phase 2: Critical Fixes (2-4 hours)
|
||||
1. Fix `useIterableCallbackReturn` in seed_berita.ts
|
||||
2. Fix `useOptionalChain` in xcoba.ts
|
||||
3. Remove `!important` styles atau refactor CSS
|
||||
4. Fix Node.js import protocols
|
||||
|
||||
### Phase 3: Type Safety Improvement (1-2 weeks)
|
||||
1. Replace `any` dengan proper types di critical files
|
||||
2. Add type guards untuk `unknown` values
|
||||
3. Implement proper error handling types
|
||||
4. Remove unused imports dan variables
|
||||
|
||||
### Phase 4: Long-term Improvement (Ongoing)
|
||||
1. Setup Biome di CI/CD pipeline
|
||||
2. Add pre-commit hooks untuk auto-lint
|
||||
3. Regular code reviews untuk maintain quality
|
||||
4. Gradually refactor `any` to proper types
|
||||

|
||||
## 📝 Notes
|
||||
|
||||
- **Majority of issues** adalah `noExplicitAny` yang memerlukan manual effort
|
||||
- **Most auto-fixable** issues bisa diselesaikan dalam 1 command
|
||||
- **Critical errors** hanya 3 files yang harus segera di-fix
|
||||
- **Project size:** 1,951 files dengan ~9,000 issues
|
||||
- **Estimated effort:** 1-2 minggu untuk comprehensive cleanup
