Dependencies

14 direct dependencies for a fast, secure server:

• fastify - High-performance HTTP server
• @fastify/middie - Express/Connect middleware bridge (for IdP)
• @fastify/rate-limit - Rate limiting for API endpoints
• @fastify/websocket - WebSocket support for notifications
• @simplewebauthn/server - Passkey/WebAuthn authentication
• bcryptjs - Password hashing (pure JS, works on Termux/Android)
• commander - CLI command parsing
• fs-extra - Enhanced file operations
• jose - JWT/JWK handling for Solid-OIDC
• microfed - ActivityPub primitives (only when activitypub enabled)
• n3 - Turtle parsing (only used when conneg enabled)
• nostr-tools - Nostr protocol and Schnorr signature verification

• sql.js - SQLite storage for federation data (WASM, cross-platform)

Performance

This server is designed for speed. Benchmark results on a typical development machine:

Operation	Requests/sec	Avg Latency	p99 Latency
GET resource	5,400+	1.2ms	3ms
GET container	4,700+	1.6ms	3ms
PUT (write)	5,700+	1.1ms	2ms
POST (create)	5,200+	1.3ms	3ms
OPTIONS	10,000+	0.4ms	1ms

Run benchmarks yourself:

npm run benchmark

Running Tests

npm test

Currently passing: 289 tests (including 27 conformance tests)

Conformance Test Harness (CTH)

This server passes the Solid Conformance Test Harness authentication tests:

# Start server with IdP and content negotiation
JSS_PORT=4000 JSS_CONNEG=true JSS_IDP=true jss start

# Create test users
curl -X POST http://localhost:4000/.pods \
  -H "Content-Type: application/json" \
  -d '{"name": "alice", "email": "[email protected]", "password": "alicepassword123"}'

curl -X POST http://localhost:4000/.pods \
  -H "Content-Type: application/json" \
  -d '{"name": "bob", "email": "[email protected]", "password": "bobpassword123"}'

# Run CTH authentication tests
docker run --rm --network=host \
  -e SOLID_IDENTITY_PROVIDER="http://localhost:4000/" \
  -e USERS_ALICE_WEBID="http://localhost:4000/alice/#me" \
  -e USERS_ALICE_PASSWORD="alicepassword123" \
  -e USERS_BOB_WEBID="http://localhost:4000/bob/#me" \
  -e USERS_BOB_PASSWORD="bobpassword123" \
  solidproject/conformance-test-harness:latest \
  --filter="authentication"

CTH Status (v0.0.15):

• Authentication tests: 6/6 passing
