tajniak81andClaude Opus 5 f521d2b220 Web App: two sites, one tab — a server you can switch
Two locations means two full stacks, and until now the app could only ever
see the one that served it. The login screen's "Server settings" could point
it elsewhere, but as a global swap: it replaced the server rather than
adding one, and forgot the session you already had.

There is now a server picker at the bottom of the app rail, after signing
in rather than on the login screen. It names the server you are reading —
which matters most when both sites look identical — and switches in a click.

Each server is its own PocketBase with its own users, so nothing is
federated: you sign into each one once and a token is kept per server. The
home server is the one that served the app, reached same-origin through the
BFF proxy; any other is added by address and called straight from the
browser, which asks nothing new of the network — an API Server the phone app
can reach is internet-facing already.

Two things the switch turned out to need:

Views load on mount, so swapping the session alone left B's user looking at
A's cars. The RouterView is keyed on the active server and a switch returns
to the garage, since record ids belong to the server that issued them.

A request now carries the id of the server it went out to, and a 401 clears
that session rather than whatever is active when the answer lands. A page
fires half a dozen calls at once: the first rejection used to switch away
and the rest then cleared the session of the server it had switched to,
turning one stale remote token into a full sign-out.

A remote session expiring falls back to the home server with the entry left
in place to sign into again. Only Log out clears them all.

# DriverVault — Web App
Maintenance tracker for your cars: a **Vue 3 + Vite + Tailwind CSS v4** SPA served
by a small **Go backend-for-frontend (BFF)**. The BFF serves the built SPA and
reverse-proxies `/api/*` to the API Server, so the browser is always same-origin
and all data access still flows through the API Server (never PocketBase directly).
```
Browser ─► Web App BFF (:8090) ──/api/*──► API Server (:8080) ─► PocketBase
│ └── serves embedded Vue SPA
└──────────────────────────────────────► API Server at another site ─► its PocketBase
(added in the app, called straight from the browser)
```

## Requirements
- **Node 20.19+ or 22.12+** (Vite 8's floor — Node 18 is end-of-life and will not
build) and **Go 1.26+** (the `go.mod` directive). The Docker image builds on
`node:22-alpine`.
- A running **API Server** (see `../API Server`)
## Develop
Two terminals:
```powershell
# terminal 1 — API Server (see ../API Server/README.md)
cd "../API Server"; .\bin\api-server.exe
# terminal 2 — Vite dev server with hot reload (proxies /api -> :8080)
cd web; npm install; npm run dev # http://localhost:5173
```
The dev server proxies `/api/*` to the API Server (default `http://localhost:8080`,
override with `VITE_API_TARGET`), so the client uses same-origin relative URLs and
avoids CORS. It also listens on all interfaces (`host: true`) so it's reachable on
the LAN (e.g. `http://10.2.1.101:5173`).
The base URL each call goes to comes from the active server (see **More than one
server** below); with only the built-in one, that resolves to `VITE_API_BASE`
`/api`.
## Build & run (production-style)
```powershell
./server/Run-WebApp.ps1 # builds frontend, then serves on :8090
# or manually:
cd web; npm run build # outputs to ../server/dist
cd ../server; go run . # http://localhost:8090
```
Config (`server/.env`, copy from `.env.example`):
| Variable | Purpose | Default |
|---|---|---|
| `WEB_ADDR` | Listen address | `:8090` |
| `API_BASE` | API Server base URL | `http://localhost:8080` |
## Features
- **Dashboard** — one card per car: last service, odometer, next-due date/km, and
a status badge (OK / due soon ≤30d / overdue) from the Excel formulas. Add a
car by hand, or **import from service** — pick a vehicle off a connected
manufacturer account and have its details filled in (the button appears only
once an account is connected). Shared cars are labelled and gated by your access
level. **Drag a card** to rearrange the garage: the order is saved per user (so
it covers shared cars and never reorders anybody else's garage) and applied by
the API on every list. Pointer-only — the native drag events it uses don't fire
on touch.
- **What a car shows** — the gear button in a car's header picks both the
sections that car's page shows (connected service, service history, technical
checks, maintenance, fuel cost, charging cost, documents, parts, reminders —
Fuel cost off on an EV and Charging cost off on a petrol car) and which of the
14 Information rows it lists (no Differential oil on a car without one). It belongs to the car, so everyone it is shared with sees
the same page; setting it needs write access. Stored as the *hidden* sets, so
anything added in a later release is on by default, and the Information tab
itself can't be switched off.
- **Locking the layout** — the padlock in the sidebar, above the theme toggle,
holds every arrangement still at once: the garage, a car's tabs, its
Information rows, the provider's readings. It is a guard against nudging a
layout while reading it, not a permission — it is the user's own setting
(`dragLocked` on the profile, so it follows them to the next device) and says
nothing about what they may edit. Unlocked by default; while locked the drag
cursor and the hints go too.
- **Arranging the tabs** — the tabs themselves drag into any order, saved on
drop. A property of the car like the choice of which tabs show, so everyone it
is shared with sees the same bar, and it needs write access. It covers the
hidden tabs too, so switching one back on returns it to where it was, and
Information is arrangeable even though it can't be switched off. Where the
page opens is unchanged: Information, wherever it now sits in the bar.
- **Arranging the Information rows** — the rows on a car's Information tab drag
into any order, saved on drop. Also a property of the car, and it covers the
hidden rows too, so switching one back on returns it to where it was. Same
native drag events as the garage, so also pointer-only.
- **Arranging the connected service's readings** — the headline readings on that
tab drag the same way. Only what the provider reported can be arranged, so a
reading that turns up later (an EV range on a car that was parked unplugged)
joins the end rather than displacing the arrangement.
- **Car detail** — all car spec fields (engine / transmission / differential oil,
brake fluid, coolant, VIN, fuel type, …) plus tabbed histories, each with an
optional file attachment and add/edit/delete gated by your access level:
- **The connected service** (e.g. **MyToyota**) — the first tab, present for a
car linked to a manufacturer account: live readings (odometer, fuel, battery,
range, position), the vehicle record, and every section the plugin can fetch
with its raw response. Offers the provider's odometer when it is ahead of the
stored one. Every card below the live readings — the vehicle record and each
provider section — folds away, and which ones you folded is remembered per
device in localStorage. On an unlinked car the tab instead offers to connect
it to a vehicle on your account. Read under *your* account, so a car shared
from someone else shows data only if that vehicle is on your account too.
- **Service history** — date, km, computed next date/km, and changed-parts flags.
- **Technical checks** — roadworthiness inspections; result, cost, station and
the certificate's valid-until, which drives the next-due date.
- **Maintenance** — workshop visits and repairs (type/status, workshop, parts,
labour + parts cost, invoice, warranty-until).
- **Fuel cost** — refills with a summary panel (average / best / worst
consumption, cost per km, price per litre), measured between full tanks.
- **Charging cost** — the same log for an electric car: charges in kWh with
consumption in kWh/100km, km per kWh, cost per km and price per kWh,
measured between charges to the car's usual full point. Partial charges
still count towards the cost and roll into the next full one, and a charge
taken without logging it (flagged on the next session) leaves that window
uncomputed rather than reporting an implausible figure.
- **Documents** — insurance, registration, road tax, … with a renewal badge.
- **Parts** — the per-car parts catalog.
- **Reminders** — date/odometer, one-off or recurring; server-derived ones are
read-only.
Also **share** the car with other users (read/write, owner only); edit/delete
controls are hidden for read-only shares.
- **Charging** — the EV charging screen for connected Anker Solix chargers:
live status and, in own/proxy control mode, start/stop and charge-limit
controls driven by the API Server's OCPP Central System.
- **Settings** — split into tabs: *Personal settings* — account (name / email
verification / password), appearance (theme light/dark/system, locale, date
format, currency, font size), profile (avatar, bio), data **export/import**,
and the account-deletion state machine; *Integrations* (Toyota, Anker Solix);
*Users* for admins; and *Organization* (create your own — which makes you its
admin — or rename/delete the one you administer).
- **Users** — user management (list / create / role / reset password / delete)
as the admin-only Settings tab; `/admin` redirects there for old links.
- **Theming** — light/dark/system app-wide (Tailwind v4 class strategy); `prefs.js`
toggles `.dark` on `<html>` and applies the saved theme/locale/date/font.
## More than one server
Two sites, two full DriverVault stacks — and one browser tab. The server picker
sits at the bottom of the app rail (after signing in, not on the login screen):
it names the server you are reading right now, and switches between them in a
click.
- **The home server** is the one that served the app, reached same-origin through
the BFF's `/api` proxy. It is always in the list and can't be removed.
- **Any other server** is added by address — `https://garage.example.com`; the
`/api` is appended for you if you leave the path off — and is called **straight
from the browser**, not relayed through the BFF. That server therefore has to be
reachable from wherever the browser is, which it already is if the phone app
talks to it.
- **A session per server.** Each server is its own PocketBase with its own users,
so a token can't be carried across: you sign into each one once, and after that
switching needs no password. Sessions live in `localStorage` under
`cc_session_<id>`, the list under `cc_servers`, the active one under
`cc_active_server`.
- **Switching goes back to the garage**, because record ids belong to the server
that issued them — a car page can't survive the change.
- **An expiring remote session doesn't sign you out of the app**: that server's
token is dropped, the app falls back to the home server, and the entry stays in
the list to sign into again. Only *Log out* clears every server at once.
The remote server must allow the Web App's origin in **`CORS_ALLOW_ORIGINS`**
(API Server setting, `*` by default — so this works out of the box, and only
needs attention on a server whose list has been narrowed). Nothing needs to be
configured on the server you are browsing *from*.
## Auth & access
Login proxies to the API Server, which relays PocketBase's own token — there is
no JWT the server mints and no server-side session list. The token is stored
client-side, per server, and sent as `Authorization` on every call; each request
is pinned to the server that was active when it went out, so one server's `401`
can never drop another's session. `auth.js` exposes
`isAdmin` and the current profile; the router guards `public` / `admin` routes.
Cars are per-user (owned + shared), and the UI mirrors the server's read / write
/ owner access levels.
