Platform Features Guide (Phase 13)

MyCLI generates observability, security, tenancy, feature flags, and search modules for production Node.js apps.

Quick start

my add observability
my security setup              # or: my add security
my add tenancy
my add feature-flags
my add search --provider meilisearch
my doctor

Features

| Command | Module | Purpose | |---------|--------|---------| | my add observability | src/platform/observability/ | Pino logging, OpenTelemetry, /metrics | | my add security / my security setup | src/platform/security/ | Helmet, CORS, rate limiting | | my add tenancy | src/platform/tenancy/ | Multi-tenant context via header | | my add feature-flags | src/platform/feature-flags/ | JSON-backed feature toggles | | my add search | src/platform/search/ | Meilisearch or Elasticsearch |

Each command generates source files, docs/<feature>.md, env vars in .env.example, and updates PLATFORM.md.

Tenancy modes

When adding tenancy, choose an isolation strategy:

my add tenancy --mode single-db              # default — shared DB, row-level filtering
my add tenancy --mode schema-per-tenant      # PostgreSQL schema per tenant
my add tenancy --mode db-per-tenant          # dedicated DATABASE_URL per tenant

| Mode | Generated files | Env vars | |------|-----------------|----------| | single-db | tenant.middleware.ts, context | TENANT_HEADER, DEFAULT_TENANT | | schema-per-tenant | + tenant.resolver.ts (schema) | + TENANT_SCHEMA_PREFIX | | db-per-tenant | + tenant.resolver.ts (DB URL) | + DATABASE_URL_<TENANT> |

The selected mode is stored in .myclirc.json under extensions.tenancyMode and documented in docs/tenancy.md.

Search providers

my add search --provider meilisearch    # default
my add search --provider elasticsearch

Feature flag aliases

my add feature-flags
my add flags              # alias

Manager

| Package | Responsibility | |---------|----------------| | @mycli-cli/platform-manager | Observability, security, tenancy, feature-flags, search |
