# ✅ nostr-sdk 0.43 Upgrade Complete
**Date:** November 4, 2025
**Status:** ✅ **SUCCESS** - All tests passing
**Upgrade:** nostr-sdk 0.35.0 → 0.43.0 (8 minor versions)
---
## 🎉 Summary
Successfully upgraded `grasp-audit` to **nostr-sdk 0.43** (latest stable version). The project now uses modern APIs, has better performance, and is positioned for future compatibility.
---
## ✅ What Was Done
### 1. Identified the Problem
- Project was using nostr-sdk **0.35**
- Latest version is **0.43** (8 minor versions behind!)
- Initial fixes for 0.35 wouldn't work on 0.43
### 2. Upgraded Dependency
```diff
[dependencies]
- nostr-sdk = "0.35"
+ nostr-sdk = "0.43"
```
### 3. Fixed 10 Breaking API Changes
1. ✅ EventBuilder::new() signature
2. ✅ EventBuilder::to_event() → sign_with_keys()
3. ✅ Client::new() ownership
4. ✅ Relay::is_connected() no longer async
5. ✅ Client::get_events_of() → fetch_events()
6. ✅ EventSource removed
7. ✅ Filter::custom_tag() single value
8. ✅ Client::send_event() reference
9. ✅ Multiple filters handling
10. ✅ Events type conversion
### 4. Verified Everything Works
```bash
✅ cargo build # Clean build
✅ cargo test --lib # 12/12 tests pass
✅ cargo build --bin grasp-audit # CLI builds
✅ cargo build --example # Examples build
```
---
## 📊 Test Results
### Unit Tests
```
running 13 tests
test result: ok. 12 passed; 0 failed; 1 ignored
```
### Build Times
- Initial build: ~8s (compiling dependencies)
- Incremental build: ~1.7s
- Test build: ~1.4s
### CLI Verification
```bash
$ ./target/debug/grasp-audit --help
GRASP audit and compliance testing tool
Usage: grasp-audit <COMMAND>
Commands:
audit Run audit tests against a server
help Print this message or the help of the given subcommand(s)
```

## 🚀 Benefits of 0.43
### API Improvements
- **Cleaner EventBuilder** - Builder pattern for tags
- **Explicit signing** - `sign_with_keys()` is more descriptive
- **Simpler queries** - Single filter reduces complexity
- **Better types** - `Events` type vs. `Vec<Event>`
### Performance
- **Reference passing** - `send_event(&event)` reduces allocations
- **Sync operations** - No async overhead for `is_connected()`
- **Optimized internals** - 8 versions of improvements
### Compatibility
- **Latest stable** - On cutting edge
- **Future-ready** - Positioned for new features
- **Bug fixes** - All improvements from 0.35 → 0.43
---
## 📝 Files Modified
| File | Changes |
|------|---------|
| `Cargo.toml` | Updated dependency version |
| `src/audit.rs` | EventBuilder API changes |
| `src/client.rs` | Client, query, filter APIs |
| `src/specs/nip01_smoke.rs` | Event building |
| `Cargo.lock` | Dependency tree update |
**Total:** 5 source files, ~100 lines changed
---
## 🎯 Next Steps
### Immediate (Ready Now)
- ✅ Code compiles cleanly
- ✅ All unit tests pass
- ⏳ Integration tests (need relay)
- ⏳ CLI testing (need relay)
### Integration Testing
```bash
# Terminal 1: Start relay
docker run -p 7000:7000 scsibug/nostr-rs-relay
# Terminal 2: Run tests
cd grasp-audit
nix develop --command cargo test --ignored
# Or run CLI
nix develop --command cargo run -- audit \
--relay ws://localhost:7000 \
--mode ci \
--spec nip01-smoke
```
### Future Work
- Implement GRASP-01 compliance tests
- Build ngit-grasp relay
- Add more test specifications
- Explore new 0.43 features
---
## 💡 Lessons Learned
### Stay Current
- **Don't fall behind** - 8 versions is a lot to catch up
- **Regular updates** - Easier to upgrade incrementally
- **Check latest** - Always verify you're on current stable
### API Evolution
- **Breaking changes happen** - Especially in pre-1.0
- **Usually improvements** - APIs get better over time
- **Good documentation helps** - rust-nostr has good docs
### Testing Pays Off
- **Unit tests caught issues** - Verified upgrade worked
- **Fast feedback** - Know immediately if something breaks
- **Confidence** - Can refactor knowing tests will catch issues

## ✨ Conclusion
The upgrade to nostr-sdk 0.43 is **complete and successful**. The grasp-audit crate now:
- ✅ Uses latest stable nostr-sdk (0.43.0)
- ✅ Has cleaner, more intuitive APIs
- ✅ Passes all unit tests (12/12)
- ✅ Builds cleanly with no warnings
