# Component Size Guidelines
|
||||
|
||||
All components must be under 150 lines of code (LOC). This refactor follows atomic design principles.
|
||||
|
||||
## Component Categories
|
||||
|
||||
### Atoms (< 50 LOC)
|
||||
Single-purpose, highly reusable components:
|
||||
- DataList
|
||||
- StatCard
|
||||
- ActionButton
|
||||
- LoadingState
|
||||
- EmptyState
|
||||
- StatusBadge
|
||||
- IconButton
|
||||
|
||||
### Molecules (50-100 LOC)
|
||||
Combinations of atoms for specific use cases:
|
||||
- SearchBar (Input + Icon)
|
||||
- DataCard (Card + Content + Actions)
|
||||
- FormField (Label + Input + Error)
|
||||
- FilterBar (Multiple filters)
|
||||
|
||||
### Organisms (100-150 LOC)
|
||||
Complex components combining molecules:
|
||||
- DataTable (with sorting, filtering, pagination)
|
||||
- Dashboard (multiple stat cards and charts)
|
||||
- FormBuilder (dynamic form generation)
|
||||
|
||||
## Refactoring Large Components
|
||||
|
||||
### Before (200+ LOC):
|
||||
```typescript
|
||||
function ProjectDashboard() {
|
||||
// 50 lines of state and logic
|
||||
// 150 lines of JSX with embedded components
|
||||
return <div>...</div>
|
||||
}
|
||||
```
|
||||
|
||||
### After (< 50 LOC):
|
||||
```typescript
|
||||
function ProjectDashboard(props) {
|
||||
return (
|
||||
<JSONPageRenderer
|
||||
schema={dashboardSchema}
|
||||
data={props}
|
||||
functions={{ calculateCompletionScore }}
|
||||
/>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
## Hook Extraction
|
||||
|
||||
Move logic out of components into hooks:
|
||||
|
||||
### Before:
|
||||
```typescript
|
||||
function MyComponent() {
|
||||
const [items, setItems] = useState([])
|
||||
const [search, setSearch] = useState('')
|
||||
const filtered = items.filter(i => i.name.includes(search))
|
||||
const [page, setPage] = useState(1)
|
||||
const paginated = filtered.slice((page-1)*10, page*10)
|
||||
// ... more logic
|
||||
return <div>...</div>
|
||||
}
|
||||
```
|
||||
|
||||
### After:
|
||||
```typescript
|
||||
function MyComponent() {
|
||||
const [items, setItems] = useKV('items', [])
|
||||
const { filtered } = useSearchFilter({ items, searchFields: ['name'] })
|
||||
const { items: page } = usePagination({ items: filtered, pageSize: 10 })
|
||||
return <DataList items={page} renderItem={...} />
|
||||
}
|
||||
```
|
||||
|
||||
## JSON-Driven Pages
|
||||
|
||||
For data-heavy pages, use JSON configuration:
|
||||
|
||||
1. Create JSON schema in `/src/config/pages/`
|
||||
2. Define data bindings and layout
|
||||
3. Implement computed functions
|
||||
4. Use JSONPageRenderer
|
||||
|
||||
This reduces component size from 200+ LOC to < 50 LOC.
|
||||
|
||||
## Composition Over Inheritance
|
||||
|
||||
Build complex UIs by composing simple components:
|
||||
|
||||
```typescript
|
||||
<Card>
|
||||
<CardHeader>
|
||||
<Heading level={2}>Title</Heading>
|
||||
<StatusBadge status="active" />
|
||||
</CardHeader>
|
||||
<CardContent>
|
||||
<DataList items={data} renderItem={renderItem} />
|
||||
</CardContent>
|
||||
<CardFooter>
|
||||
<ActionButton label="Add" onClick={handleAdd} />
|
||||
</CardFooter>
|
||||
</Card>
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **Easier to Test**: Small components = simple tests
|
||||
2. **Easier to Understand**: Clear, focused responsibility
|
||||
3. **Easier to Reuse**: Composable building blocks
|
||||
4. **Easier to Maintain**: Changes are localized
|
||||
5. **Better Performance**: Smaller re-render boundaries

Individual field validation and state management.
|
||||
|
||||
```typescript
|
||||
import { useFormField } from '@/hooks/forms'
|
||||
|
||||
const field = useFormField({
|
||||
name: 'email',
|
||||
defaultValue: '',
|
||||
rules: [
|
||||
{
|
||||
validate: (val) => val.includes('@'),
|
||||
message: 'Must be valid email'
|
||||
}
|
||||
]
|
||||
})
|
||||
|
||||
<input
|
||||
value={field.value}
|
||||
onChange={(e) => field.onChange(e.target.value)}
|
||||
onBlur={field.onBlur}
|
||||
/>
|
||||
{field.touched && field.error && <span>{field.error}</span>}

||||
---
|
||||
|
||||
### useForm
|
||||
Form submission with async support.
|
||||
|
||||

|
||||
import { useForm } from '@/hooks/forms'
|
||||
|
||||
const { submit, isSubmitting } = useForm({
|
||||
fields: { email: {...}, password: {...} },
|
||||
onSubmit: async (values) => {
|
||||
await api.submit(values)
|
||||
}
|
||||
})
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Always use functional updates with useCRUD:**
|
||||
```typescript
|
||||
// ✅ CORRECT
|
||||
crud.create(newItem)
|
||||
crud.update(id, updates)
|
||||
|
||||
// ❌ WRONG - Never manually modify items
|
||||
setItems([...items, newItem]) // Can cause data loss!
|
||||
```
|
||||
|
||||
2. **Combine hooks for complex scenarios:**
|
||||
```typescript
|
||||
const [items, setItems] = useKV('data', [])
|
||||
const crud = useCRUD({ items, setItems })
|
||||
const { filtered } = useSearchFilter({ items })
|
||||
const { sorted } = useSort({ items: filtered })
|
||||
const { items: page } = usePagination({ items: sorted })
|
||||
```
|
||||
|
||||
3. **Use computed data sources for derived state:**
|
||||
```typescript
|
||||
useDataSource({
|
||||
type: 'computed',
|
||||
compute: (data) => ({
|
||||
total: data.items?.length || 0,
|
||||
completed: data.items?.filter(i => i.done).length || 0
|
||||
}),
|
||||
dependencies: ['items']
|
||||
})
|
||||
```

# JSON Page Configuration Guide
|
||||
|
||||
## Overview
|
||||
Define entire pages using JSON configuration instead of writing React components.
|
||||
|
||||
## Page Schema Structure
|
||||
|
||||
```json
|
||||
{
|
||||
"id": "my-page",
|
||||
"layout": {
|
||||
"type": "vertical",
|
||||
"spacing": "6",
|
||||
"sections": [...]
|
||||
},
|
||||
"dataBindings": ["prop1", "prop2"],
|
||||
"components": [...]
|
||||
}
|
||||
```
|
||||
|
||||
## Layout Types
|
||||
|
||||
### Vertical Layout
|
||||
```json
|
||||
{
|
||||
"type": "vertical",
|
||||
"spacing": "6",
|
||||
"sections": [
|
||||
{ "type": "header", "title": "Page Title", "description": "Description" },
|
||||
{ "type": "grid", "items": "statCards", "columns": { "md": 2, "lg": 3 } },
|
||||
{ "type": "cards", "items": "dashboardCards" }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Grid Layout
|
||||
```json
|
||||
{
|
||||
"type": "grid",
|
||||
"items": "myItems",
|
||||
"columns": {
|
||||
"sm": 1,
|
||||
"md": 2,
|
||||
"lg": 3,
|
||||
"xl": 4
|
||||
},
|
||||
"gap": "4"
|
||||
}
|
||||
```
|
||||
|
||||
## Data Binding
|
||||
|
||||
### Simple Bindings
|
||||
```json
|
||||
{
|
||||
"dataBinding": "files.length"
|
||||
}
|
||||
```
|
||||
|
||||
### Complex Expressions
|
||||
```json
|
||||
{
|
||||
"dataBinding": "flaskConfig.blueprints.reduce((acc, bp) => acc + bp.endpoints.length, 0)"
|
||||
}
|
||||
```
|
||||
|
||||
### Computed Data Sources
|
||||
```json
|
||||
{
|
||||
"dataSource": {
|
||||
"type": "computed",
|
||||
"compute": "calculateCompletionScore"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Component Types
|
||||
|
||||
### Stat Cards

||||
"icon": "Shield",
|
||||
"title": "Test Coverage",
|
||||
"dataBinding": "tests.coverage",
|
||||
"description": "of code tested",
|
||||
"color": "text-green-500"
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Usage in React
|
||||
|
||||
```typescript
|
||||
import { JSONPageRenderer } from '@/components/JSONPageRenderer'
|
||||
import pageSchema from '@/config/pages/my-page.json'
|
||||
|
||||
function MyPage(props) {
|
||||
const functions = {
|
||||
calculateScore: (data) => {
|
||||
// Custom calculation logic
|
||||
return Math.round((data.completed / data.total) * 100)
|
||||
}
|
||||
}
|
||||
|
||||
return (
|
||||
<JSONPageRenderer
|
||||
schema={pageSchema}
|
||||
data={props}
|
||||
functions={functions}
|
||||
/>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
1. **No Code Deployment**: Update UI without code changes
|
||||
2. **Consistent Design**: Enforced design patterns
|
||||
3. **Rapid Prototyping**: Build pages in minutes
|
||||
4. **Easy Maintenance**: Clear structure and readability
|
||||
5. **Type Safety**: Still benefits from TypeScript
|
||||
|
||||
## Migration Strategy
|
||||
|
||||
1. Start with simple stat-heavy pages (dashboards)
|
||||
2. Define JSON schema for page
|
||||

### [502 Bad Gateway Error Fix](./502_ERROR_FIX.md)
|
||||
Comprehensive guide for fixing 502 Bad Gateway errors in Codespaces/local development.
|
||||
|
||||
**Quick Fix:**
|
||||
```bash
|
||||
# Run the diagnostic script
|
||||
bash scripts/diagnose-502.sh
|
||||
|
||||
# Then restart the dev server
|
||||
npm run kill
|
||||
npm run dev
|
||||
### After: JSON-Driven (< 50 LOC)
|
||||
```typescript
|
||||
function ProjectDashboard(props) {
|
||||
return (
|
||||
<JSONPageRenderer
|
||||
schema={dashboardSchema}
|
||||
data={props}
|
||||
functions={{ calculateCompletionScore }}
|
||||
/>
|
||||
)
|
||||
}
|
||||
```
|
||||
|
||||
**Key Changes Made:**
|
||||
- ✅ Updated `vite.config.ts` to use port 5000 (was 5173)
|
||||
- ✅ Server already configured to bind to `0.0.0.0`
|
||||
- ✅ Updated CI/CD workflows to use `npm install` instead of `npm ci`
|
||||
## Best Practices
|
||||
|
||||
## Common Issues
|
||||
1. **Extract Logic to Hooks**
|
||||
- Keep components focused on rendering
|
||||
- Move state management to custom hooks
|
||||
- Use data hooks for CRUD operations
|
||||
|
||||
### 1. Port Mismatch
|
||||
**Symptom**: 502 errors when accessing Codespaces URL
|
||||
**Cause**: Vite running on different port than forwarded
|
||||
**Fix**: Ensure vite.config.ts uses port 5000
|
||||
2. **Use JSON for Data-Heavy Pages**
|
||||
- Dashboards with multiple metrics
|
||||
- Settings pages
|
||||
- Status displays
|
||||
|
||||
### 2. Workspace Dependencies
|
||||
**Symptom**: CI/CD fails with `EUNSUPPORTEDPROTOCOL`
|
||||
**Cause**: `npm ci` doesn't support workspace protocol
|
||||
**Fix**: Use `npm install` or switch to pnpm
|
||||
3. **Compose Small Components**
|
||||
- Build complex UIs from atomic pieces
|
||||
- Each component has single responsibility
|
||||
- Maximum 150 LOC per component
|
||||
|
||||
### 3. Server Not Accessible
|
||||
**Symptom**: 502 errors even when server is running
|
||||
**Cause**: Server bound to localhost only
|
||||
**Fix**: Use `host: '0.0.0.0'` in vite.config.ts (already done)
|
||||
|
||||
### 4. MIME Type Errors
|
||||
**Symptom**: Resources refused as wrong content type
|
||||
**Cause**: Usually secondary to 502 errors
|
||||
**Fix**: Fix 502 errors first, MIME issues resolve automatically
|
||||
|
||||
## Quick Commands
|
||||
|
||||
```bash
|
||||
# Check if server is running
|
||||
lsof -i :5000
|
||||
|
||||
# Kill server on port 5000
|
||||
npm run kill
|
||||
|
||||
# Start dev server
|
||||
npm run dev
|
||||
|
||||
# Run diagnostics
|
||||
bash scripts/diagnose-502.sh
|
||||
|
||||
# Check Codespaces ports
|
||||
gh codespace ports
|
||||
|
||||
# Install dependencies (with workspace support)
|
||||
npm install
|
||||
```
|
||||
|
||||
## File Changes Made
|
||||
|
||||
| File | Change | Status |
|
||||
|------|--------|--------|
|
||||
| `vite.config.ts` | Port 5173 → 5000 | ✅ Fixed |
|
||||
| `.github/workflows/ci.yml` | `npm ci` → `npm install` (4 places) | ✅ Fixed |
|
||||
| `.github/workflows/e2e-tests.yml` | `npm ci` → `npm install` | ✅ Fixed |
|
||||
| `scripts/diagnose-502.sh` | Created diagnostic script | ✅ New |
|
||||
| `docs/502_ERROR_FIX.md` | Created comprehensive guide | ✅ New |
|
||||
|
||||
## Next Steps After Fixes
|
||||
|
||||
1. **Restart Development Server**
|
||||
```bash
|
||||
npm run kill # Kill existing processes
|
||||
npm run dev # Start fresh
|
||||
4. **Always Use Functional Updates**
|
||||
```typescript
|
||||
// ✅ CORRECT
|
||||
setItems(current => [...current, newItem])
|
||||
|
||||
// ❌ WRONG - Can cause data loss
|
||||
setItems([...items, newItem])
|
||||
```
|
||||
|
||||
2. **Verify in Browser**
|
||||
- Open Codespaces forwarded URL for port 5000
|
||||
- Should see React app load without errors
|
||||
- Check browser console - no 502s
|
||||
## Quick Start
|
||||
|
||||
3. **Test CI/CD**
|
||||
- Push changes to trigger workflow
|
||||
- Verify `npm install` succeeds
|
||||
- Build should complete successfully
|
||||
|
||||
4. **Long-term Improvements**
|
||||
- Consider migrating to pnpm for better workspace support
|
||||
- Add health check endpoint for monitoring
|
||||
- Document port configuration for team
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
If issues persist after applying fixes:
|
||||
|
||||
1. **Check the diagnostic output**:
|
||||
```bash
|
||||
bash scripts/diagnose-502.sh
|
||||
1. **Use existing hooks:**
|
||||
```typescript
|
||||
import { useCRUD, useSearchFilter } from '@/hooks/data'
|
||||
```
|
||||
|
||||
2. **Verify Codespaces port forwarding**:
|
||||
- Open Ports panel in VS Code
|
||||
- Ensure port 5000 is forwarded
|
||||
- Set visibility to Public or Private to Org
|
||||
|
||||
3. **Check server logs**:
|
||||
- Look for errors in terminal where dev server runs
|
||||
- Common issues: missing deps, syntax errors, port conflicts
|
||||
|
||||
4. **Clear Vite cache**:
|
||||
```bash
|
||||
rm -rf node_modules/.vite
|
||||
npm run dev
|
||||
2. **Create JSON page schema:**
|
||||
```json
|
||||
{
|
||||
"id": "my-page",
|
||||
"layout": { ... },
|
||||
"statCards": [ ... ]
|
||||
}
|
||||
```
|
||||
|
||||
5. **Rebuild dependencies**:
|
||||
```bash
|
||||
rm -rf node_modules package-lock.json
|
||||
npm install
|
||||
npm run dev
|
||||
3. **Render with JSONPageRenderer:**
|
||||
```typescript
|
||||
<JSONPageRenderer schema={mySchema} data={props} />
|
||||
```
