# NetX Windows packaging

**Linux is unchanged:** keep using your own PostgreSQL and `NETX_DATABASE_URL` with `scripts/start_netx.sh`. Nothing under this folder is required on Linux.

This directory builds a Windows deliverable with:

- Optional **bundled** portable PostgreSQL **or** **external** existing Postgres
- API-hosted UI (`web/dist`) — no separate Vite process for end users
- Program / data split so upgrades do not wipe the database
- Manual update script + auto-update **manifest contract** (fetch not implemented yet)

## What users get

| Artifact | How |
|----------|-----|
| `NetX-x.y.z-win64.zip` | `build_release.ps1` |
| `NetX-Setup-x.y.z.exe` | Compile `installer/netx.iss` with [Inno Setup](https://jrsoftware.org/isinfo.php) after staging |

## Build (developer machine)

Prerequisites: Python 3.11+, Node 20+, PowerShell, network (to download PG binaries once).

```powershell
cd netx
# Optional: download portable Postgres into packaging\postgres\pgsql
powershell -ExecutionPolicy Bypass -File .\packaging\download_postgres.ps1

# Build web + stage + zip (-CreateVenv ships a ready .venv; large)
powershell -ExecutionPolicy Bypass -File .\packaging\build_release.ps1 -CreateVenv
```

Output:

- `packaging/release/netx-win64/` — stage tree
- `packaging/release/NetX-<ver>-win64.zip`

Inno Setup:

```text
ISCC.exe packaging\installer\netx.iss
```

Override version in the `.iss` or edit `#define MyAppVersion`.

## End-user install

### Setup.exe

1. Run `NetX-Setup-x.y.z.exe` (admin).
2. Files → `%ProgramFiles%\NetX\` (program root).
3. Data → `%ProgramData%\NetX\` (`.env`, `pgdata`, spool, secrets).
4. Optional post-install task runs `setup_first_run.ps1` (choose bundled vs external DB).
5. Start menu: **Start NetX** / **Stop NetX** / **Open NetX UI**.

### Zip (portable)

1. Unpack anywhere.
2. Marker `.portable` → data root is sibling `NetXData\`.
3. Target needs **Python 3.11+** on PATH unless the zip was built with `-CreateVenv`.
4. Run:

```powershell
.\packaging\setup_first_run.ps1
.\packaging\start_netx_app.ps1
```

## Database modes

| Mode | Behavior |
|------|----------|
| `bundled` | Start portable PG on `127.0.0.1:15432`, data in data-root `pgdata\` |
| `external` | Do not start PG; use `NETX_DATABASE_URL` (same as today / Linux) |
| unset | Treated as **external** |

Existing Windows deploys that only set `NETX_DATABASE_URL` keep working: never set `NETX_DB_MODE=bundled` unless you want the portable engine.

## Manual update

```powershell
.\packaging\update_netx.ps1 -PackagePath .\NetX-0.3.0-win64.zip
```

Stops services, replaces program folders (`netx_api`, `web`, `packaging`, `postgres`, …), **keeps** the data root, restarts. Schema migrations still run via Alembic on API start.

## Auto-update (reserved)

See `manifest.example.json`. Future: set `NETX_UPDATE_URL` + `NETX_UPDATE_CHANNEL`; a checker will download the zip and call `update_netx.ps1`. Not implemented in this phase.
