+# Node Dependency Matrix
+
+This sample is a TypeScript application built to validate Keploy cloud record/replay against a broad dependency matrix.
+
+What it exposes:
+
+- incoming HTTP
+- incoming gRPC
+- outgoing HTTPS
+- outgoing HTTP/2
+- outgoing gRPC
+- outgoing MySQL
+- outgoing Postgres
+- outgoing Mongo
+- outgoing Redis
+- outgoing Kafka
+- outgoing SQS-over-HTTPS
+- outgoing generic TLS traffic
+- a noisy endpoint
+- an expected replay failure endpoint
+- duplicate-friendly endpoints for static dedup verification
+
+## Quick start
+
+```bash
+cd samples-typescript/node-dependency-matrix
+npm install
+npm run build
+bash k8s/deploy-kind.sh
+APP_URL=http://localhost:30081 bash scripts/record_traffic.sh
+```
+
+If the default host ports are already occupied, override them:
+
+```bash
+HOST_PROXY_PORT=31080 HOST_APP_PORT=31081 HOST_GRPC_PORT=31090 bash k8s/deploy-kind.sh
+APP_URL=http://localhost:31081 bash scripts/record_traffic.sh
+```
+
+Optional incoming gRPC traffic:
+
+```bash
+GRPC_TARGET=localhost:30090 bash scripts/send_grpc_traffic.sh
+```
+
+## Docker Compose
+
+For a non-Kubernetes local stack:
+
+```bash
+cd samples-typescript/node-dependency-matrix
+npm install
+bash scripts/compose_up.sh
+APP_URL=http://localhost:38081 bash scripts/record_traffic.sh
+GRPC_TARGET=localhost:39090 bash scripts/send_grpc_traffic.sh
+```
+
+To stop it:
+
+```bash
+bash scripts/compose_down.sh
+```
+
+If `38081` or `39090` are occupied:
+
+```bash
+APP_HTTP_PORT=48081 APP_GRPC_PORT=49090 bash scripts/compose_up.sh
+APP_URL=http://localhost:48081 bash scripts/record_traffic.sh
+GRPC_TARGET=localhost:49090 bash scripts/send_grpc_traffic.sh
+```
+
+## Keploy expectations
+
+The machine-readable contract is:
+
+```bash
+fixtures/expected-values.json
+```
+
+Use it later in Playwright or manual verification for:
+
+- testcase counts
+- required and acceptable mock kinds
+- scenario-to-mock-kind mapping
+- the exact HTTP and gRPC traffic plans
+- hosted UI + Helm expectations for Kind
+- total mock count ranges
+- dedup expectations
+- expected replay pass/noisy/fail scenarios
+
+## Kubernetes
+
+The full Kind and hosted UI flow is in:
+
+```bash
+k8s/README.md
+```
