Implementation Status

Last updated: 2025-09-25

Current Snapshot (Demo + Observability)

• ✅ In-memory Jaeger demo validated (Dependencies graph visible)
  • Edge confirmed: upstream-service → rdcp-demo-app
  • Helper scripts: run-inmemory-demo.sh (start/seed) and stop-inmemory-demo.sh (cleanup)
• ✅ OpenTelemetry integration (Node) via @rdcp.dev/otel-plugin
  • Auto-instrumentations enabled; trace correlation in RDCP debug logs
  • Verified export to Jaeger OTLP HTTP
• ✅ RDCP header enforcement for /rdcp/v1/* (401 RDCP_AUTH_REQUIRED on missing/invalid headers)
• ✅ Control endpoint: demo rate limiting (429) and RDCP_AUDIT structured logging (e2e)
• ✅ Docker Compose adjusted to use SPAN_STORAGE_TYPE=memory for all-in-one
• ♻️ Database demo removed (no native modules; simpler, fully resettable demo)
• 📘 Wiki/README updated with quick local in-memory instructions

CURRENT STATUS (SDK): The RDCP SDK is production-ready across core functionality (see details below).

✅ Authentication: All 3 security levels implemented (basic, standard, enterprise + hybrid)
✅ Package imports: Both CommonJS and ESM working correctly
✅ Framework adapters: Express, Fastify, Koa all functional
✅ Test coverage: 201/201 tests passing (25 test suites)
✅ TypeScript support: Full type definitions included

This page documents the current implementation status based on actual testing.

✅ SDK IS PRODUCTION READY

All major blockers have been resolved - The SDK can be used in production applications today.

// ✅ Both import methods work perfectly
const { adapters, auth } = require('@rdcp.dev/server')    // CommonJS
import { adapters, auth } from '@rdcp.dev/server'         // ESM

// ✅ Create middleware with any authentication level
const middleware = adapters.express.createRDCPMiddleware({
  authenticator: auth.validateRDCPAuth  // Supports all security levels
})

Tested Working Features

✅ Authentication System

Status: Complete with Context7 compliance

• Basic: API key validation with constant-time comparison
• Standard: JWT Bearer token validation with scopes and expiration
• Enterprise: mTLS certificate validation with X.509 parsing
• Hybrid: Multi-method authentication support
• Test Results: 42/42 auth tests passing in both TypeScript and JavaScript

✅ Framework Adapters

Status: All adapters implemented and tested

• Express: createRDCPMiddleware() fully functional
• Fastify: createRDCPPlugin() fully functional
• Koa: createRDCPMiddleware() with error boundary support
• Test Results: 25/25 adapter tests passing
• Import Support: Both CommonJS and ESM working

✅ Validation System

Status: Complete RDCP v1.0 validation

• Schemas: All RDCP protocol schemas implemented
• Error handling: Standard RDCP error codes and responses
• Middleware: Request validation middleware for all frameworks
• Test Results: 33/33 validation tests passing

✅ Protocol Endpoints

Status: All 5 RDCP endpoints implemented

• Protocol Discovery: /.well-known/rdcp returns RDCP v1.0 structure
• Debug Discovery: /rdcp/v1/discovery shows available categories
• Runtime Control: /rdcp/v1/control enables/disables categories
• Status Monitoring: /rdcp/v1/status returns current states
• Health Check: /rdcp/v1/health returns system health

✅ Package Distribution

Status: Dual format working correctly

• CommonJS: require('@rdcp/server') returns all exports
• ESM: import('@rdcp/server') returns all exports
• TypeScript: Full type definitions included
• Build Process: Generates both CJS and ESM bundles

Legend:

• ✅ Working - Confirmed working through testing
• ⚠️ Minor Issues - Working but needs integration polish
• ❌ Broken - Not working, blocks usage

Test Results Summary

Total Tests: 201/201 passing ✅

• Authentication: 42 tests (TypeScript + JavaScript)
• Validation: 33 tests (TypeScript + JavaScript)
• Framework Adapters: 25 tests (Express, Fastify, Koa)
• Integration: 5 tests
• Main Exports: 10 tests
• Other: 15 tests

Minor Issues Remaining

⚠️ Control Endpoint Integration

Status: LOW PRIORITY - Core functionality works

• Issue: Example server validation needs adjustment for some edge cases
• Impact: Basic runtime control works, some validation edge cases need polish
• Solution: Integration testing and middleware configuration refinement
• Priority: Low - SDK core functionality is solid

Current Usability Assessment

✅ READY FOR PRODUCTION USE

All major functionality works correctly:

// ✅ Installation and imports work
npm install @rdcp.dev/server

// ✅ CommonJS usage
const { adapters, auth } = require('@rdcp/server')
const app = express()
app.use(adapters.express.createRDCPMiddleware({
  authenticator: auth.validateRDCPAuth
}))

// ✅ ESM usage  
import { adapters, auth } from '@rdcp.dev/server'
const app = express()
app.use(adapters.express.createRDCPMiddleware({
  authenticator: auth.validateRDCPAuth
}))

What Works Today

• ✅ All authentication levels (basic, standard, enterprise, hybrid)
• ✅ All framework adapters (Express, Fastify, Koa)
• ✅ Complete RDCP v1.0 protocol support
• ✅ Full TypeScript support with proper type definitions
• ✅ Comprehensive test coverage (130/130 tests passing)
• ✅ Dual package format (CommonJS + ESM)
• ✅ Context7-compliant implementation patterns

Recommended Usage

For Basic Authentication (API Key):

const { adapters, auth } = require('@rdcp/server')

// Set environment variable
process.env.RDCP_API_KEY = 'your-32-character-or-longer-api-key'

const middleware = adapters.express.createRDCPMiddleware({
  authenticator: auth.validateRDCPAuth
})

For Standard Authentication (JWT):

import { adapters } from '@rdcp/server'

const jwtAuth = (req) => {
  // Your JWT validation logic
  return { valid: true, method: 'bearer', userId: 'user123' }
}

const middleware = adapters.express.createRDCPMiddleware({
  authenticator: jwtAuth
})

For Enterprise Authentication (mTLS):

import { adapters } from '@rdcp/server'

const mtlsAuth = (req) => {
  // Your certificate validation logic
  return { valid: true, method: 'mtls', userId: 'client.example.com' }
}

const middleware = adapters.express.createRDCPMiddleware({
  authenticator: mtlsAuth
})
