First step toward Redis-backed sessions. Adds the shared `ioredis` connection that every downstream consumer (session storage, OBO token cache, …) will inject via the new `REDIS_CLIENT` DI token. What lands: - `ioredis@^5.10.1` as a direct dependency. Chosen by ADR-0010 for its mature Sentinel support — single-instance URL today, Sentinel-HA configuration plumbing lands with the production infrastructure ADR. - `.env.example` promotes `REDIS_URL` from its previous future-vars comment block into an active variable, with a default that matches `infra/local/.env` (REDIS_PASSWORD + REDIS_PORT). The Sentinel-style keys (`REDIS_SENTINEL_HOSTS`, `REDIS_SENTINEL_NAME`, `REDIS_TLS`) stay in the future-vars comment until the prod deploy lands. - `apps/portal-bff/src/config/check-redis-config.ts` — boot-time guard mirroring the existing four: `assertDatabaseUrl` / `assertEntraConfig` / `assertSessionSecret`. Refuses to start if `REDIS_URL` is unset, not a valid `redis://` / `rediss://` URL, missing the password (the local stack requires one), or still set to the `redis_dev_change_me` .env.example placeholder. Returns a typed `RedisConfig` with parsed `host` + `port` for downstream observability. - `apps/portal-bff/src/redis/redis.token.ts` — `REDIS_CLIENT` string token + `Redis` type alias. Same shape as `ENTRA_CONFIG` / `MSAL_CLIENT`. - `apps/portal-bff/src/redis/redis.module.ts` — `RedisModule` exposes a factory provider for `REDIS_CLIENT`. The factory builds the `ioredis` client from the parsed config, caps `maxRetriesPerRequest` at 3 (so an unreachable Redis surfaces a command-time error instead of an infinite reconnect storm), and wires `connect` / `ready` / `error` / `close` / `reconnecting` events into the Pino stream with the `redis` Pino context. Non-global on purpose — modules import it to state "I depend on Redis". - `main.ts` calls `assertRedisConfig()` alongside the other three validators. `AppModule` imports `RedisModule`. Verification: - `nx run-many -t lint test build --projects=portal-bff` — green. - 62 / 62 specs (was 52; +10 across the config validator spec and the module spec — the latter exercises both the happy path against an unreachable URL — `ioredis` constructs lazily so no real socket opens — and the missing-env failure mode). - Boot smoke (with the local Compose stack running): the `redis` Pino context shows `redis.connect` → `redis.ready` lines on startup; killing the Redis container later produces `redis.close` / `redis.reconnecting`. What this PR explicitly does NOT do: - Mount `express-session` + `connect-redis` middleware. The next PR wires the session cookie (`__Host-portal_session`) + the encrypted payload + the lookup middleware that attaches `user` to every request. - Plug the callback into session creation. Auth still ends with a Pino log + redirect; the SPA still sees the user anonymous on the next request.
