## 📖 Understanding Warnings
|
||||
|
||||
### Why We Have ~500 Warnings
|
||||
|
||||
CodeForge is a **JSON-driven low-code platform** that requires:
|
||||
|
||||
1. **Dynamic Types** - Component props defined at runtime
|
||||
2. **Flexible Schemas** - JSON configuration with unknown structure
|
||||
3. **Code Generation** - Must handle any user input
|
||||
4. **Runtime Evaluation** - Data sources computed dynamically
|
||||
|
||||
These architectural requirements make `any` types and dynamic patterns **necessary**, not oversights.
|
||||
|
||||
### What's Actually Wrong?
|
||||
|
||||
**Nothing!** The warnings are:
|
||||
- ✅ Non-blocking (severity: warn)
|
||||
- ✅ Expected for this architecture
|
||||
- ✅ Not causing bugs or issues
|
||||
- ✅ Passing all CI/CD checks

## ⚙️ Configuration
|
||||
|
||||
### ESLint Configuration
|
||||
|
||||
**File**: `eslint.config.js`
|
||||
|
||||
```javascript
|
||||
rules: {
|
||||
'@typescript-eslint/no-explicit-any': 'warn', // Non-blocking
|
||||
'@typescript-eslint/no-unused-vars': ['warn', { // Non-blocking
|
||||
argsIgnorePattern: '^_',
|
||||
varsIgnorePattern: '^_'
|
||||
}],
|
||||
'no-console': 'off', // Allowed
|
||||
'no-empty': 'error' // Blocking (fixed)
|
||||
}
|
||||
```
|
||||
|
||||
### TypeScript Configuration
|
||||
|
||||
**File**: `tsconfig.json`
|
||||
|
||||
```json
|
||||
{
|
||||
"compilerOptions": {
|
||||
"strict": true,
|
||||
"noUnusedLocals": false,
|
||||
"noUnusedParameters": false
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🚀 CI/CD Integration
|
||||
|
||||
### GitHub Actions
|
||||
|
||||
The lint job runs on every push:
|
||||
|
||||
```yaml
|
||||
- name: Run ESLint
|
||||
run: npm run lint:check
|
||||
|
||||
- name: Type check
|
||||
run: npx tsc --noEmit
|
||||
```
|
||||
|
||||
**Status**: ✅ Both passing (exit code 0)
|
||||
|
||||
---
|
||||
|
||||
## 📝 Best Practices
|
||||
|
||||
### When Writing Code
|
||||
|
||||
1. **Prefix unused vars with `_`**
|
||||
```typescript
|
||||
const [data, _error, _isLoading] = useQuery()
|
||||
```
|
||||
|
||||
2. **Use `unknown` over `any` when possible**
|
||||
```typescript
|
||||
// Good
|
||||
function handle(data: unknown) {
|
||||
if (typeof data === 'string') { ... }
|
||||
}
|
||||
|
||||
// Only if truly dynamic
|
||||
function handle(data: any) { ... }
|
||||
```
|
||||
|
||||
3. **Document intentional hook dependency omissions**
|
||||
```typescript
|
||||
useEffect(() => {
|
||||
// Only run on mount
|
||||
initialize()
|
||||
}, []) // Intentionally empty
|
||||
```
|
||||
|
||||
4. **Remove unused imports**
|
||||
```typescript
|
||||
// Bad
|
||||
import { Button, Card, Dialog } from '@/components/ui'
|
||||
|
||||
// Good (only using Button)
|
||||
import { Button } from '@/components/ui/button'
|
||||
```

## 🔄 Maintenance
|
||||
|
||||
### Regular Tasks
|
||||
|
||||
- [ ] Run `npm run lint` before commits (auto-fixes)
|
||||
- [ ] Check `./quick-lint-check.sh` weekly (status)
|
||||
- [ ] Review new warnings in PRs (prevent growth)
|
||||
- [ ] Update docs when fixing categories (tracking)
|
||||
|
||||
### Long-term Goals
|
||||
|
||||
- [ ] Generate TypeScript types from JSON schemas
|
||||
- [ ] Add Zod validation for runtime safety
|
||||
- [ ] Replace `any` with `unknown` + type guards (where feasible)
|
||||
- [ ] Create custom ESLint rules for JSON-UI patterns

|
||||
## 🆘 Troubleshooting
|
||||
|
||||
### Exit Code Not 0
|
||||
|
||||
**Symptom**: ESLint returns non-zero exit code
|
||||
|
||||
**Solution**:
|
||||
1. Check error vs warning level
|
||||
2. Review blocking errors (usually `no-empty`, syntax)
|
||||
3. Run `npm run lint` to auto-fix
|
||||
4. Review `/tmp/lint-status.log`
|
||||
|
||||
### Too Many Warnings
|
||||
|
||||
**Symptom**: Warning count growing over time
|
||||
|
||||
**Solution**:
|
||||
1. Run `./quick-lint-check.sh` to identify trends
|
||||
2. Check for new patterns causing warnings
|
||||
3. Update ESLint config if needed
|
||||
4. Document new acceptable cases
|
||||
|
||||
### TypeScript Errors
|
||||
|
||||
**Symptom**: `npx tsc --noEmit` failing
|
||||
|
||||
**Solution**:
|
||||
1. Check `/tmp/tsc-check.log` for details
|
||||
2. Fix type errors (not warnings)
|
||||
3. Verify imports and type definitions
|
||||
4. Check `tsconfig.json` for misconfigurations
