# Tx OS

A bilingual (Arabic / English) internal "office OS" web platform. Single-tenant,
self-hosted, designed to live behind a TLS-terminating reverse proxy on a
private VPS or on-prem host.

The repo is a pnpm monorepo containing:

| Package                              | Purpose                                            |
| ------------------------------------ | -------------------------------------------------- |
| `artifacts/api-server`               | Express 5 + Socket.IO + Drizzle ORM API            |
| `artifacts/tx-os`                    | React 19 + Vite SPA (the user-facing app)          |
| `artifacts/mockup-sandbox`           | Internal component preview server (dev-only)       |
| `lib/db`                             | Drizzle schema + migrations                        |
| `lib/api-zod` + `lib/api-client-react` | OpenAPI-generated Zod schemas + React Query hooks |
| `scripts`                            | DB seed + maintenance scripts                      |

## Features

- **Glassmorphism OS UI** with animated gradient backgrounds and an app grid / dock.
- **Bilingual** (RTL Arabic + LTR English) with per-user persisted locale.
- **Session auth** (`express-session` + Postgres-backed `connect-pg-simple`,
  bcrypt password hashing) with full RBAC (admin / user roles + role-permission
  matrix + group-derived permissions).
- **Real-time** chat / notifications / executive-meeting alerts via Socket.IO.
- **Executive Meetings module** — scheduling, change requests, approvals,
  optimistic locking on postpones, audit log, and a Playwright-rendered HTML
  PDF export.
- **S3-compatible object storage** with signed-URL uploads (production: MinIO;
  local dev: built-in filesystem driver — no extra services required).

## Quick start (Docker)

The fastest path to a running stack on a Linux VPS with Docker installed.

```bash
git clone <this-repo>
cd tx-os
cp .env.example .env
# Edit .env — at minimum change SESSION_SECRET, POSTGRES_PASSWORD,
# S3_SECRET_ACCESS_KEY, SEED_ADMIN_PASSWORD, SEED_USER_PASSWORD.
$EDITOR .env

docker compose build
docker compose up -d db minio minio-init
docker compose run --rm migrate          # one-shot: pnpm run migrate (db push + seed)
docker compose up -d api web
```

After this, the running stack exposes:

| Service          | Default host port | URL                            |
| ---------------- | ----------------- | ------------------------------ |
| SPA (`web`)      | `3000`            | `http://<host>:3000/`          |
| API (`api`)      | `8080`            | `http://<host>:8080/api/healthz` |
| MinIO console    | not exposed       | (proxy to `:9001` if you need it) |
| `mockup-sandbox` | `8081`            | dev profile only — `docker compose --profile dev up -d mockup-sandbox` then `http://<host>:8081/__mockup` |

Front the SPA (port `WEB_PORT`, default `3000`) with Caddy / Nginx / Traefik
for TLS and HTTP/2; bind the API port (`API_PORT`, default `8080`) to
`127.0.0.1` in production so the edge proxy is the sole external entry.

### Default seeded accounts

| Username | Password                           | Role  |
| -------- | ---------------------------------- | ----- |
| `admin`  | value of `SEED_ADMIN_PASSWORD`     | admin |
| `ahmed`  | value of `SEED_USER_PASSWORD`      | user  |

Both are seeded by `docker compose run --rm migrate` and **only** if they don't
already exist (the seed is idempotent on conflict).

### Common compose commands

```bash
docker compose logs -f api               # tail API logs
docker compose exec db psql -U tx tx_os  # psql shell
docker compose run --rm migrate          # re-run migrations (safe to repeat)
docker compose down                      # stop everything (data persists)
docker compose down -v                   # stop AND wipe volumes (DANGER)
```

## Local development (without Docker)

You can run the stack natively if you have Node 24+, pnpm 10, and Postgres 16.

```bash
pnpm install
createdb tx_os
export DATABASE_URL=postgres://localhost/tx_os
export PORT=8080 BASE_PATH=/ ALLOWED_ORIGINS=http://localhost:25785
export SESSION_SECRET=$(openssl rand -hex 32)
export PRIVATE_OBJECT_DIR=/local/private
export PUBLIC_OBJECT_SEARCH_PATHS=/local/public
# Note: with no S3_ENDPOINT set, the API falls back to the local-FS storage
# driver and persists uploads under ./storage/. Safe for development only.

pnpm --filter db run push           # apply schema
pnpm --filter scripts run seed      # seed admin/ahmed accounts
pnpm --filter @workspace/api-server dev
# In another terminal:
PORT=25785 BASE_PATH=/ pnpm --filter @workspace/tx-os dev
```

## Configuration reference

Every option is read from environment variables. See `.env.example` for the
complete list with comments. Highlights:

| Variable                          | Purpose                                                                |
| --------------------------------- | ---------------------------------------------------------------------- |
| `DATABASE_URL`                    | Postgres connection string. **Required.**                              |
| `SESSION_SECRET`                  | HMAC key for session cookies + local-driver upload tokens. **Required in production.** |
| `ALLOWED_ORIGINS`                 | Comma-separated CORS allow-list. Defaults to `*` (dev only).           |
| `STORAGE_DRIVER`                  | `s3` or `local`. Defaults to `s3` if `S3_ENDPOINT` set, else `local`.  |
| `S3_ENDPOINT` etc.                | MinIO / S3 connection. Required when `STORAGE_DRIVER=s3`.              |
| `PRIVATE_OBJECT_DIR`              | Path inside the bucket for private uploads, e.g. `/tx-private/private`.|
| `PUBLIC_OBJECT_SEARCH_PATHS`      | Comma-separated bucket paths searched by `GET /storage/public-objects/*`. |
| `LOCAL_STORAGE_ROOT`              | Filesystem root used by the local driver. Defaults to `./storage`.     |
| `SEED_ADMIN_PASSWORD` / `SEED_USER_PASSWORD` | Required by the seed script in production.                  |
| `SMTP_*`                          | Optional outbound mail config for Executive Meetings notifications.    |
| `LOG_LEVEL`                       | pino log level. Defaults to `info`.                                    |

### Storage drivers

The API server has two object-storage backends, selected automatically:

- **`s3`** (production): targets any S3-compatible endpoint (MinIO, AWS S3, R2,
  Backblaze B2, ...) via `@aws-sdk/client-s3` + presigned PUT URLs.
- **`local`** (dev fallback, default when `S3_ENDPOINT` is unset): persists
  files under `LOCAL_STORAGE_ROOT` and issues HMAC-signed upload URLs that
  the API server validates and accepts on `PUT /api/storage/_local/upload`.
  Single-host only; not suitable for production.

The route layer is unaware of which driver is active — both expose the same
`StoredObject` interface in `lib/objectStorage.ts`.

## Tests

```bash
pnpm --filter @workspace/api-server build
pnpm --filter @workspace/api-server start &        # boot API on 8080
pnpm --filter @workspace/api-server test           # node --test suite
pnpm --filter @workspace/tx-os test:e2e            # Playwright UI tests
```

The `test` workflow chains all of the above. Tests use the same database
specified in `DATABASE_URL` and clean up after themselves with `LIKE`-prefixed
fixture rows.

## Production checklist

Before fronting Tx OS with a public domain:

1. **Set every secret in `.env`.** No defaults in production.
2. **Run behind TLS.** Caddy / Nginx / Traefik should terminate HTTPS and
   forward to `web` on `${WEB_PORT}`. The API server trusts `X-Forwarded-For`
   from the first proxy hop (`app.set("trust proxy", 1)`).
3. **Restrict the API port.** The `api` service should never be exposed
   directly to the internet — only `web` is intended to be reachable.
4. **Back up the volumes.** `db_data` and `minio_data` are the only stateful
   surfaces. Snapshot them on a schedule.
5. **Rotate seeded passwords.** The first thing an admin should do is change
   the seeded `admin` and `ahmed` passwords from the user-management screen.
6. **Review `threat_model.md`.** Document-level threat model lives in the repo
   root and lists the trust boundaries this deployment relies on.

## Project conventions

- **Package manager**: pnpm 10. The repo refuses to install with npm/yarn.
- **Node**: 24 LTS. Older Nodes will not run the API bundle.
- **TypeScript**: 5.9, strict mode, project-references build (`pnpm typecheck`).
- **API contracts**: hand-written Zod schemas in `lib/api-zod` are the source
  of truth; the React-Query client in `lib/api-client-react` is generated
  from the same OpenAPI spec via Orval.
- **Migrations**: Drizzle Kit. `pnpm --filter db run push-force` for dev,
  `pnpm --filter db run push` for production.
