Keeps technical concerns out of business code in a ddd-ts-kit project. Logging, metrics, tracing, error reporting, the audit trail, retry, timeout, circuit breaker, caching and rate limiting are applied from outside the use cases (the composition root, bus middlewares, adapters), on the standard interfaces of the kernel. Use when adding logs, metrics, traces, an error tracker, an audit log, resilience or a cache, when choosing a logger, when code needs a correlation id, the tenant or the…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cross-cutting concerns A handler that logs, measures, retries, reports and audits is five concerns hiding one use case. Business code states the business; everything else is attached from outside, in `src/platform/` and in adapters. `@ddd-ts-kit/aspects`, `audit`, `redis` and `tracing` are refused in `domain/` and `application/` even when an allow-list names them, and tracing is imported by the platform, `main.ts` and `apps/` only (`tracing/platform-only`). ## Where each concern goes | Need | Put it | With | |---|---|---| | log and measure every use case | bus middlewares, `src/platform/buses/` | `loggingMiddleware`, `metricsMiddleware` | | the logger itself | `src/platform/observability/create-logger.ts` | the kernel `Logger` port; `stack.logger` chooses the adapter: `stdout` (default), `pino` or `winston` | | trace the application | `src/platform/observability/tracing.ts`, first import of `main.ts`, and the instrumentation given to the kernel module | [tracing.md](tracing.md) | …

How to install
mdr add gbourgeat/ddd-ts-kit/cross-cutting@sha256:8cee282ee3677d27The line at the top of this page pins the label git:20261019.3419ca3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
