NodeJS RIC Rewrite for Node.js 24 and Lambda Managed Instances

Key Changes

Core Architecture:

  • Migrated to TypeScript with ESM-first environment
  • Targets Node.js 22+ exclusively
  • Implements two-dimensional multi-concurrency model for Lambda Managed Instance (Multiconcurrency) compatibility
  • Replaced Make/shell scripts with npm-based build system

Handler & Context Updates:

  • Removed callback-based handler support (promise-based only)
  • Eliminated legacy context.succeed/fail/done methods
  • Removed legacy callbackWaitsForEmptyEventLoop getters/setters

Developer Experience:

  • Native RIE testing support with single build command
  • Introduced InvokeStore package for trace ID propagation via AsyncLocalStorage

Runtime Behavior:

  • No BeforeExit event loop waiting (pure runtime loop)
  • Worker thread count defaults to logical CPU count
  • Configurable via AWS_LAMBDA_NODEJS_WORKER_COUNT
