# Username-First with UUID Fallback
|
||||
|
||||
## Overview
|
||||
|
||||
The entire system now uses **usernames as the primary identifier** with **UUID fallback** for all user/creator lookups across routes and APIs.
|
||||
|
||||
This means:
|
||||
- Users visit `/creators/john-doe` (preferred) or `/creators/<uuid>` (also works)
|
||||
- Users visit `/passport/alice-developer` (preferred) or `/passport/<uuid>` (also works)
|
||||
- Users visit `/ethos/artists/bob-musician` (preferred) or `/ethos/artists/<uuid>` (also works)
|
||||
|
||||

|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Core Utility: Identifier Resolver (`code/lib/identifier-resolver.ts`)
|
||||
|
||||
**New file** that provides helper functions:
|
||||
|
||||
```typescript
|
||||
isUUID(str) // Check if string is UUID format
|
||||
resolveIdentifierToCreator(id) // Resolve username/UUID → creator object
|
||||
resolveIdentifierToUserId(id) // Resolve username/UUID → UUID
|
||||
resolveIdentifierToUsername(id) // Resolve UUID → username
|
||||
```
|
||||
|
||||
### 2. Creators API Endpoint (`code/server/index.ts`)
|
||||
|
||||
**Updated** `GET /api/creators/:identifier` to:
|
||||
- Accept username OR UUID in the `:identifier` parameter
|
||||
- Try **username first** (preferred)
|
||||
- Fall back to **UUID lookup** if username lookup fails
|
||||
- Return 404 if neither works
|
||||
|
||||
```javascript
|
||||
// Examples that now work:
|
||||
GET /api/creators/john-doe // ✅ Username lookup
|
||||
GET /api/creators/550e8400-... // ✅ UUID lookup fallback
|
||||
```
|
||||
|
||||
### 3. Creators Profile Component (`code/client/pages/creators/CreatorProfile.tsx`)
|
||||
|
||||
**Updated** to:
|
||||
- Import UUID/identifier resolver helpers
|
||||
- Accept both username and UUID as route parameters
|
||||
- Resolve UUID to username for canonical URL redirect (optional)
|
||||
- Maintain backwards compatibility with old UUID-based URLs
|
||||
|
||||
### 4. Ethos Artist Profile (`code/client/pages/ethos/ArtistProfile.tsx`)
|
||||
|
||||
**Updated** to:
|
||||
- Import identifier resolver helpers
|
||||
- Accept both username and userId as route parameters
|
||||
- Resolve username → userId before API call
|
||||
- Handle both patterns seamlessly
|
||||
|
||||
### 5. Passport Profile (`code/client/pages/ProfilePassport.tsx`)
|
||||
|
||||
**Already supported** username-first with UUID fallback:
|
||||
- Has built-in `isUuid()` function
|
||||
- Tries `getProfileByUsername()` first
|
||||
- Falls back to `getProfileById()` if username lookup fails
|
||||
- No changes needed - already implemented!
|
||||
|
||||
### 6. Creator Profile Validation (`code/api/creators.ts`)
|
||||
|
||||
**Enforced usernames as required**:
|
||||
- Username must be provided when creating creator profile
|
||||
- Username must be unique (409 Conflict if duplicate)
|
||||
- Username is normalized to lowercase
|
||||
- Validation on both client and server
|
||||

## Routes That Support Username-First with UUID Fallback
|
||||
|
||||
| Route | Type | Status |
|
||||
|-------|------|--------|
|
||||
| `/creators/:identifier` | Frontend | ✅ Updated |
|
||||
| `/passport/:identifier` | Frontend | ✅ Already working |
|
||||
| `/ethos/artists/:identifier` | Frontend | ✅ Updated |
|
||||
| `/api/creators/:identifier` | Backend | ✅ Updated |
|
||||

|
||||
|
||||
## How It Works: Flow Example
|
||||
|
||||
### Username Lookup (Preferred)
|
||||
|
||||
```
|
||||
User visits: /creators/john-doe
|
||||
↓
|
||||
CreatorProfile component
|
||||
↓
|
||||
Component calls: GET /api/creators/john-doe
|
||||
↓
|
||||
Server checks: isUUID("john-doe") → false
|
||||
↓
|
||||
Query database: SELECT * FROM aethex_creators WHERE username = "john-doe"
|
||||
↓
|
||||
Return creator data ✅
|
||||
```
|
||||
|
||||
### UUID Lookup (Fallback)
|
||||
|
||||
```
|
||||
User visits: /creators/550e8400-e29b-41d4-a716-446655440000
|
||||
↓
|
||||
CreatorProfile component
|
||||
↓
|
||||
Component calls: GET /api/creators/550e8400-e29b-41d4-a716-446655440000
|
||||
↓
|
||||
Server checks: isUUID("550e8400-...") → true
|
||||
↓
|
||||
Query database: SELECT * FROM aethex_creators WHERE username = "550e8400-..."
|
||||
↓
|
||||
No match, try UUID fallback:
|
||||
SELECT * FROM aethex_creators WHERE id = "550e8400-..."
|
||||
↓
|
||||
Return creator data ✅
|
||||
```
|
||||
|
||||
### Username Resolution (For Ethos Artists)
|
||||
|
||||
```
|
||||
User visits: /ethos/artists/bob-musician
|
||||
↓
|
||||
ArtistProfile component
|
||||
↓
|
||||
Component calls: resolveIdentifierToUserId("bob-musician")
|
||||
↓
|
||||
Utility function calls: GET /api/creators/bob-musician
|
||||
↓
|
||||
Creator found! Extract user_id = "550e8400-..."
|
||||
↓
|
||||
Component calls: GET /api/ethos/artists?id=550e8400-...
|
||||
↓
|
||||
Return artist data ✅
|
||||
```
|
||||
|

|
||||
|
||||
## Benefits
|
||||
|
||||
✅ **SEO-friendly URLs** - Usernames are more human-readable than UUIDs
|
||||
✅ **Backwards compatible** - Old UUID-based links still work
|
||||
✅ **Consistent behavior** - All user profile routes work the same way
|
||||
✅ **User-friendly** - Share `/creators/john-doe` instead of UUID
|
||||
✅ **Enforced usernames** - Everyone has a username, eliminates UUID-only profiles
|
||||
|
||||

|
||||
|
||||
## Implementation Details
|
||||
|
||||
### UUID Detection
|
||||
|
||||
```typescript
|
||||
// UUID regex pattern (standard RFC 4122)
|
||||
const uuidPattern = /^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/i;
|
||||
|
||||
function isUUID(str: string): boolean {
|
||||
return uuidPattern.test(str);
|
||||
}
|
||||
```
|
||||
|
||||
### Lookup Priority
|
||||
|
||||
For any identifier:
|
||||
1. **If it matches UUID pattern** → Try UUID lookup directly
|
||||
2. **If it doesn't match UUID pattern** → Try username lookup first, then UUID fallback
|
||||
3. **If both fail** → Return 404 Not Found
|
||||
|
||||
### Username Normalization
|
||||
|
||||
- Usernames stored as **lowercase**
|
||||
- Lookups are **case-insensitive**
|
||||
- Users can visit `/creators/John-Doe`, `/creators/JOHN-DOE`, `/creators/john-doe` - all work
|
||||
- URLs always redirect to the canonical username (lowercase)
|
||||

||||

|
||||
|
||||
## Client-Side API Functions
|
||||
|
||||
### Using the Resolver Utilities
|
||||
|
||||
```typescript
|
||||
import {
|
||||
isUUID,
|
||||
resolveIdentifierToCreator,
|
||||
resolveIdentifierToUserId,
|
||||
resolveIdentifierToUsername
|
||||
} from '@/lib/identifier-resolver';
|
||||
|
||||
// Check if string is UUID
|
||||
if (isUUID(userInput)) {
|
||||
// It's a UUID, use as user ID
|
||||
}
|
||||
|
||||
// Resolve identifier to creator profile
|
||||
const creator = await resolveIdentifierToCreator("john-doe");
|
||||
// or
|
||||
const creator = await resolveIdentifierToCreator("550e8400-...");
|
||||
|
||||
// Get just the user ID
|
||||
const userId = await resolveIdentifierToUserId("john-doe");
|
||||
|
||||
// Get just the username
|
||||
const username = await resolveIdentifierToUsername("550e8400-...");
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Database Consistency
|
||||
|
||||
### Username Uniqueness
|
||||
|
||||
- Usernames are unique in `aethex_creators` table
|
||||
- Enforced in API validation (returns 409 if duplicate)
|
||||
- Usernames are indexed for fast lookups
|
||||
|
||||
### Required Field
|
||||
|
||||
- `username` column is **NOT NULL**
|
||||
- All profiles created after enforcement have usernames
|
||||
- Migration: Existing profiles without usernames should be given auto-generated usernames
|
||||
|
||||
---
|
||||
|
||||
## Future Improvements
|
||||
|
||||
1. **Profile slugs** - Use human-friendly slugs instead of usernames (e.g., `/profile/john-doe-developer`)
|
||||
2. **Username changes** - Allow users to change usernames with proper redirects
|
||||
3. **Vanity URLs** - Custom profile URLs (e.g., `/john`)
|
||||
4. **Social aliases** - Link multiple usernames to one profile
|
||||

## Testing
|
||||
|
||||
### Test Cases
|
||||
|
||||
```
|
||||
✅ GET /api/creators/john-doe → Returns creator
|
||||
✅ GET /api/creators/JOHN-DOE → Returns same creator (case-insensitive)
|
||||
✅ GET /api/creators/550e8400-... → Returns creator (UUID fallback)
|
||||
✅ GET /api/creators/nonexistent → Returns 404
|
||||
✅ GET /api/creators/invalid-uuid → Tries username, then returns 404
|
||||
|
||||
✅ /creators/john-doe → Loads profile
|
||||
✅ /creators/550e8400-... → Loads profile (UUID fallback)
|
||||
✅ /passport/john-doe → Loads passport
|
||||
✅ /passport/550e8400-... → Loads passport (UUID fallback)
|
||||
✅ /ethos/artists/bob-musician → Loads artist
|
||||
✅ /ethos/artists/550e8400-... → Loads artist (UUID fallback)
|
||||
```

||||
✅ **Username-First with UUID Fallback is now implemented across the entire system.**
