|
|
|
|
## Overview
|
|
|
|
Successfully created both TypeScript and Go client libraries for the Distributed Directory Consensus Protocol (NIP-XX), mirroring functionality while following language-specific idioms.
|
|
|
|
## TypeScript Client (`pkg/protocol/directory-client/`)

## Implementation Notes
|
|
|
|
### TypeScript-Specific Features
|
|
- Observable-based event streams with RxJS
|
|
- Promise-based async operations
|
|
- Optional chaining and nullish coalescing
|
|
- Class-based architecture
|
|
|
|
### Go-Specific Features
|
|
- Goroutine-safe with mutexes
|
|
- Struct-based API (not classes)
|
|
- Multiple return values for error handling
|
|
- Zero-dependency beyond internal packages
|
|
- Memory-efficient with manual caching control
|
|
|
|
### Differences from Protocol Package
|
|
|
|
The client libraries provide **high-level conveniences** over the base protocol package:
|
|
|
|
**Protocol Package (`pkg/protocol/directory/`):**
|
|
- Low-level event parsing
|
|
- Event construction
|
|
- Message validation
|
|
- Tag handling
|
|
|
|
**Client Libraries:**
|
|
- Identity relationship tracking
|
|
- Trust score aggregation
|
|
- Event filtering & collection
|
|
- Replication decision-making
|
|
- Trust graph analysis
|
|
|
|
### Trust Score Calculation
|
|
|
|
Both implementations use identical weighted averaging:
|
|
- High trust: 100 points
|
|
- Medium trust: 50 points
|
|
- Low trust: 25 points
|
|
|
|
Expired acts are excluded from calculation.
|
|
|
|
### Known Limitations
|
|
|
|
1. **IdentityTag Structure**: The Go implementation currently uses `NPubIdentity` field and maps it as both identity and delegate, as the actual I tag structure in the protocol needs clarification.
|
|
|
|
2. **GroupTagAct Fields**: The Go struct has `GroupID`, `TagName`, `TagValue`, `Actor` fields which differ from the TypeScript expectation of `targetPubkey` and `groupTag`. Helper functions adapted accordingly.
|
|
|
|
3. **TypeScript Signature Verification**: Not yet implemented - requires schnorr library integration.
|
|
|
|
4. **Event Store Integration**: TypeScript uses AppleSauce's EventStore; Go version designed for custom integration.
|
|
|
|
## Testing Status
|
|
|
|
- **TypeScript**: Package structure complete, ready for `npm install && npm build`
|
|
- **Go**: Successfully compiles with `go build .`, zero errors, one minor efficiency warning
|
|
|
|
## Next Steps
|
|
|
|
1. Implement unit tests for both libraries
|
|
2. Add integration tests with actual event data
|
|
3. Implement schnorr signature verification in TypeScript
|
|
4. Clarify and align IdentityTag structure across implementations
|
|
5. Add benchmark tests for performance-critical operations
|
|
6. Create example applications demonstrating usage
|
|
|
|
## File Counts
|
|
|
|
- TypeScript: 10 files (6 source, 4 config/docs)
|
|
- Go: 5 files (4 source, 1 doc)
|
|
- Total: 15 new files
|
|
|
|
## Lines of Code
|
|
|
|
- TypeScript: ~1,800 lines
|
|
- Go: ~725 lines
|
|
- Total: ~2,525 lines
|
|
|
|
## Documentation
|
|
|
|
Both libraries include:
|
|
- Comprehensive README with usage examples
|
|
- Inline code documentation
|
|
- Package-level documentation
|
|
- API reference
|
|
|
|
The implementations successfully mirror each other while respecting language idioms and ecosystem conventions.
