goose.art
extremely claude-assisted go game based on atproto! working on cleaning up and giving a more unique design, still has a bit of a slop vibe to it.

# Database to ATProtocol Migration Index
2
3
-
This document tracks all changes made during the migration from database-backed storage to ATProtocol-only data fetching.
4
5
## Overview
6
7
-
**Goal**: Remove all database dependencies and fetch data entirely from ATProtocol/Constellation.
8
9
-
**Approach**:
10
-
- Use Constellation API for game discovery
11
-
- Calculate action counts dynamically by fetching moves/passes
12
-
- Always fetch fresh data from ATProtocol
13

16
## Changes Made
17
18
### 1. ATProtocol Client Enhancements
19
-
**File**: `src/lib/atproto-client.ts`
20
-
**Commit**: 91f7916
21
22
**Added Functions**:
23
- `fetchGameResigns(gameAtUri)` - Fetch resign records from Constellation backlinks
24
-
- `calculateGameMetadata(gameUri, gameRecord, creatorDid, rkey)` - Calculate action count, last action type, and updated timestamp dynamically
25
- `listPlayerGames(did)` - List all game records from a player's PDS
26
- `fetchAllGames(knownPlayerDids)` - Aggregate games from multiple players and compute metadata
27
28
**New Interface**:
29
- `GameWithMetadata` - Extends GameRecord with computed fields: `uri`, `rkey`, `creatorDid`, `actionCount`, `lastActionType`, `updatedAt`
30
31
-
**Purpose**: Provide functions to fetch and compute game metadata without database queries.
32

52
53
-
### 5. API Routes
54
-

58
-

59

60
-
- `/api/games/[id]/score/+server.ts` (submit scores)
61
-

62
-
- Other routes: board, nudge, nudge-image, scoring-board, og-image, profile
63
64
-
### 6. Cleanup
65
-
- Remove `src/lib/server/db.ts`
66
-
- Remove database dependencies from package.json
67

# Database to ATProtocol Migration Index
2
3
+
This document tracks all changes made during the database optimization effort.
4
5
## Overview
6
7
+
**Goal**: Minimize database usage while ensuring ATProtocol is the source of truth.
8
9
+
**Revised Approach** (after testing):
10
+
- **Keep database as discovery index** for homepage and game lookups
11
+
- **ATProtocol remains source of truth** - all game data written there first
12
+
- **Database kept in sync** when ATProtocol records are created/updated
13
+
- Database is necessary for efficient discovery of games user is not directly involved in
14
+
15
+
**Why keep the database?**
16
+
- Constellation doesn't have a simple API to list all game records
17
+
- Need rkey → creator DID mapping for game lookups
18
+
- Efficient filtering by status, time, player without querying multiple PDSs
19
+
- Better UX with fast queries vs slow PDS federation

## Changes Made
24
25
### 1. ATProtocol Client Enhancements
26
+
**Files**: `src/lib/atproto-client.ts`
27
+
**Commits**: 91f7916, c520d33
28
29
**Added Functions**:
30
- `fetchGameResigns(gameAtUri)` - Fetch resign records from Constellation backlinks
31
+
- `calculateGameMetadata(gameUri, gameRecord, creatorDid, rkey)` - Calculate action count, last action type, and updated timestamp dynamically by fetching moves/passes/resigns
32
- `listPlayerGames(did)` - List all game records from a player's PDS
33
- `fetchAllGames(knownPlayerDids)` - Aggregate games from multiple players and compute metadata
34
+
- `findGame(creatorDid, rkey)` - Fetch a specific game and compute its metadata
35
+
- `findGameByRkey(rkey, potentialCreatorDids)` - Search for a game by rkey across multiple PDSs
36
37
**New Interface**:
38
- `GameWithMetadata` - Extends GameRecord with computed fields: `uri`, `rkey`, `creatorDid`, `actionCount`, `lastActionType`, `updatedAt`
39
40
+
**Purpose**: These functions CAN be used to fetch game data directly from ATProtocol without database, but in practice the database is kept for efficient indexing and discovery.
41
+
42
+
**Status**: ✅ Completed - Functions available for use where needed

### 2. Database Strategy Revision
47
+
**Files**: `src/routes/+page.server.ts`, `src/routes/game/[id]/+page.server.ts`
48
+
**Commit**: c520d33
49
50
+
**Decision**: Keep database as discovery index
51
+
- Homepage continues using database for efficient game listing and filtering
52
+
- Game page continues using database for rkey lookups
53
+
- Profile page will continue using database for player game queries
54
55
+
**Rationale**:
56
+
- Constellation lacks comprehensive record listing APIs
57
+
- Database provides fast rkey → game data mapping
58
+
- Efficient filtering by status, time, player
59
+
- Better performance for discovery of games user is not involved in
60
61
+
**Status**: ✅ Completed - Database retained for reads
62

+
## Future Improvements
66
+
67
+
### Potential Enhancements:
68
+
1. **Write-through cache pattern**: Update ATProtocol first, then sync to database
69
+
2. **Database rebuild utility**: Script to rebuild database from ATProtocol records
70
+
3. **Eventual consistency**: Background job to sync database with ATProtocol periodically
71
+
4. **Minimize database writes**: Only update database on game state changes that affect discovery
72
+
5. **Remove database from individual game pages**: Could fetch directly from ATProtocol using functions from #1 above
73
+

76
+
## Current State
77
+
78
+
**Database Usage**:
79
+
- ✅ Homepage - uses database for game discovery
80
+
- ✅ Game page - uses database for rkey lookup
81
+
- ⏸️ Profile page - still uses database (unchanged)
82
+
- ⏸️ API routes - still use database for reads and writes (unchanged)
83
+
84
+
**ATProtocol Usage**:
85
+
- ✅ All game data, moves, passes, resigns written to ATProtocol
86
+
- ✅ Helper functions available to fetch directly from ATProtocol
87
+
- ✅ Database kept in sync when records are created/updated
