# Run the whole app locally — Balinyaar bring-up runbook

The one copy-pasteable procedure for standing up **both** projects on one machine and watching a real,
authenticated request cross the wire. Established by **Refinement Phase 0**
([refinement-phase-0-bring-up.md](refinement-phase-0-bring-up.md)).

After this you have: the API on `https://localhost:5002` (against a local SQL Server), the web client on
`http://localhost:3000`, and a working phone-OTP login backed by the real backend. **Auth is the only real
domain** until [Refinement Phase 4](refinement-phase-4-frontend-de-mock.md) — everything else in the UI is
still an in-browser mock.

---

## Prerequisites

- **.NET 10 SDK** (`dotnet --version`) — preview is fine.
- **Node.js 20+** and **npm** (`node --version`).
- **Docker** (Desktop or engine) for the local database — or your own SQL Server on `localhost:1433`.

---

## One-time setup

### 1. Trust the ASP.NET Core HTTPS dev certificate

Without this the browser (and `fetch`) rejects `https://localhost:5002` and every call fails with an opaque
network error.

```bash
dotnet dev-certs https --trust
```

Accept the OS prompt. (macOS/Windows trust the cert; on Linux see the .NET docs for the per-distro step.)

### 2. Start a local SQL Server

From `server/`:

```bash
cd server
docker compose up -d
```

This runs SQL Server 2022 (Developer edition) on `localhost:1433` with a **dev-only** SA password
(`Balinyaar_Dev1433`, defined in `server/docker-compose.yml` — not a secret, never used in production).
Give it ~20–30s on first start (`docker compose ps` shows `healthy`).

> Already have a SQL Server? Skip this and point the connection string in step 3 at it instead.

### 3. Point the API at the local database (via user-secrets — never a committed file)

The committed `appsettings*.json` carry a **placeholder** connection string on purpose. Supply the real
local one through `dotnet user-secrets` so no working credential ever lands in git. From the API project:

```bash
cd server/src/API/Baya.Web.Api
dotnet user-secrets set "ConnectionStrings:SqlServer" "Server=localhost,1433;Database=Baya;User Id=sa;Password=Balinyaar_Dev1433;TrustServerCertificate=True;Encrypt=False;"
```

The `Password` must match `MSSQL_SA_PASSWORD` in `docker-compose.yml`. User-secrets auto-load only in the
Development environment, so this never affects a deployed build.

> **Env-var alternative** (e.g. for CI/containers): set `ConnectionStrings__SqlServer` (double underscore =
> the `:` config separator) instead of using user-secrets.
> PowerShell: `$env:ConnectionStrings__SqlServer = "Server=localhost,1433;Database=Baya;User Id=sa;Password=Balinyaar_Dev1433;TrustServerCertificate=True;Encrypt=False;"`
> bash: `export ConnectionStrings__SqlServer="Server=localhost,1433;Database=Baya;User Id=sa;Password=Balinyaar_Dev1433;TrustServerCertificate=True;Encrypt=False;"`

---

## Run it (two terminals)

### Terminal 1 — backend (from `server/`)

```bash
dotnet run --project src/API/Baya.Web.Api/Baya.Web.Api.csproj
```

On boot the API applies all EF migrations and seeds roles + an admin user + a sandbox payment gateway
against the (empty) local DB, then listens on **`https://localhost:5002`** — Swagger at
`https://localhost:5002/swagger`.

### Terminal 2 — frontend (from `client/`)

```bash
cd client
npm install      # first time only
npm run dev
```

Serves **`http://localhost:3000`**. It reads the API base URL from `client/.env.development`
(`NEXT_PUBLIC_API_URL = https://localhost:5002`). If you run the API on a different port/scheme, create
`client/.env.local` with your `NEXT_PUBLIC_API_URL=…` (it overrides `.env.development`, is git-ignored).

---

## Log in (the real round-trip)

1. Open **`http://localhost:3000/fa/login`**.
2. Enter an Iranian mobile number (e.g. `09120000001`) and request the code.
3. Get the 6-digit OTP one of two ways:
   - **Read the server console** (Terminal 1) — SMS is mocked, so the code is logged:
     `MOCK SMS — OTP code 123456 for phone ending in 0001`.
   - **Or hit the Development-only helper** (handy for scripts/e2e):
     `GET https://localhost:5002/api/v1/dev/last_otp/09120000001` →
     `{ "data": { "phone": "09120000001", "code": "123456" }, ... }`.
     This endpoint returns **404 outside Development** and is superseded by real SMS in
     [Refinement Phase 8](refinement-phase-8-external-rails.md).
4. Enter the code and submit → you land on the customer home.
5. **Verify in DevTools → Network:** `POST /api/v1/auth/request_otp`, `POST /api/v1/auth/verify_otp`, and
   `GET /api/v1/me` all return **200** with the `ApiResult` envelope, and there is **no CORS error** in the
   console. That is the first real authenticated request between the two projects.

---

## Good to know

- **The API speaks HTTP/2** (Kestrel `Protocols: Http2`, for gRPC). Browsers negotiate h2-over-TLS
  automatically, so `fetch` just works; for `curl` add `--http2`.
- **Only `auth` is real by default.** 21 of 22 client service domains default to an in-browser mock
  (`USE_*_MOCK = true`); the home, search, bookings, etc. are fake in-memory data until Refinement Phase 4.
- **The DB self-migrates + self-seeds**, so pointing at an empty local instance is enough. Rich demo data
  (nurses, variants, search rows) arrives in [Refinement Phase 1](refinement-phase-1-database-and-seed.md).
- **Allowed browser origins** are configuration-driven (`Cors:AllowedOrigins`), defaulting to
  `http://localhost:3000` in Development. A deployed environment lists its real web origin(s).

## Stopping / resetting

```bash
docker compose down          # stop the DB, keep its data
docker compose down -v       # stop the DB and wipe the volume (fresh migrate + seed next run)
```

## Troubleshooting

| Symptom | Fix |
| --- | --- |
| Browser: `net::ERR_CERT_AUTHORITY_INVALID` on `:5002` | Run `dotnet dev-certs https --trust` (setup step 1). |
| API startup: `Login failed for user 'sa'` / connect timeout | DB not up or wrong password — check `docker compose ps` and that the user-secrets password matches `docker-compose.yml`. |
| Console: `...has been blocked by CORS policy` | `UseCors` missing/mis-ordered, or the browser origin isn't in `Cors:AllowedOrigins`. It must sit after `UseRouting` and before the rate limiter. |
| `dotnet user-secrets` errors with "could not find UserSecretsId" | Run it from `server/src/API/Baya.Web.Api` (the project with `<UserSecretsId>`). |
