DriverVault/API Server

DriverVault — API Server

The central API Server for the DriverVault project. Written in Go (standard library only, module drivervault/apiserver). It is the single gateway between all clients (web app, phone app, Home Assistant plugin, ESP32 device) and the PocketBase database — clients never talk to PocketBase directly. The API Server authenticates to PocketBase as a superuser and all collection access rules are left null, so data is only reachable through this server.

It also serves the superadmin web panel at the server root (/).

Auth & access control

Authentication is PocketBase's own. POST /api/auth/login is proxied to the PocketBase users collection and the client keeps the token PocketBase minted; this server does not issue its own JWT. Every protected request re-resolves that token against PocketBase (auth-refresh), so a role change or a deletion takes effect immediately rather than lingering until a token expires.

POST /api/auth/login   { "email": "...", "password": "..." }  -> PocketBase { token, record }
GET  /api/auth/me      (Authorization: <token>)               -> { id, email, name, role }
GET  /api/identity     (Authorization: <token>)               -> + organization

Both Authorization: Bearer <token> and a raw Authorization: <token> are accepted (PocketBase's own SDKs send the latter).

Roles

users.role is user | admin | superadmin (empty is treated as user).

Role	Can
user	their own cars, service records, parts, profile
admin	the above, plus manage users within their own organization
superadmin	everything, across all organizations, plus the PocketBase connection and plugins

Guards worth knowing: an admin cannot create or edit a superadmin, cannot move users between organizations, and nobody can change their own role or delete their own account. An organization cannot be deleted while it still has members.

Organizations

organizations is the tenant collection; users.organization is the membership. A superadmin spans all organizations; an admin is scoped by the server to their own. Users may have no organization at all.

Creating one is self-service: any user who does not already belong to an organization may POST /api/orgs, and becomes that organization's admin and first member in the same request (if the promotion fails the new organization is rolled back, so it is never left with nobody able to administer it). A user who already belongs to one is refused — membership is a single relation, so creating a second would mean silently abandoning the first.

A superadmin is the exception: they create organizations without joining them, since they already span every tenant.

From there an admin manages their own organization — rename it, or delete it once they are its only member. Deleting it detaches and demotes them back to a plain user before the record is removed, so the organization is empty when it goes. A superadmin may rename or delete any organization, but still only once it has no members at all.

Per-user car ownership + sharing

Cars are not a global list. cars.owner marks ownership and car_shares grants other users read or write access. Every car/service/part handler is gated by requireCarAccess:

• read — view the car, its service records and parts.
• write — edit the car and full service/part CRUD.
• owner only — delete the car and manage its shares.

Data model

Collection	Purpose	Key fields
cars	one per car	name, make, model, year, registration, registrationCountry, vin, fuelType, buildDate, firstRegistrationDate, currentKm, serviceIntervalDays (365), serviceIntervalKm (15000), technicalCheckIntervalDays (365), oilSpec, transmissionOilSpec, differentialOilSpec, brakeFluidSpec, coolantSpec, owner
service_records	the service log	car, date, km, changed_oil, changed_engine_air_filter, changed_cabin_air_filter, notes
technical_checks	roadworthiness inspections (przegląd techniczny / MOT / TÜV)	car, date, result (passed | failed), cost, station, valid_until, notes
parts	per-car parts catalog	car, name, part_number, category, notes
fuel_entries	refuelling log (efficiency derived on read)	car, date, km, liters, cost, full_tank, missed_fill, station, notes
charging_sessions	EV charging log, the same shape as the refuelling one (kWh/100km derived on read)	car, date, km, kwh, cost, full_charge, missed_session, location, notes
maintenance_entries	workshop visits & repairs (outside routine service)	car, date, km, type, status, workshop, parts_used, labor_cost, parts_cost, invoice_number, warranty_until, notes
car_documents	paperwork (insurance, registration, road tax, …)	car, type, title, provider, reference, issue_date, expiry_date, cost, notes
reminders	date/odometer reminders (some auto-derived)	car, title, type, due_date, due_km, repeat_days, repeat_km, done, done_at, notes
car_shares	grants another user access to a car	car, user, permission (read | write)
organizations	tenants	name (unique)
control_audit	OCPP control-command audit trail	user, charger, action, result, timestamp
users	login + profile (built-in auth collection)	name, email, avatar, role (user | admin | superadmin), organization, bio, theme, locale, date_format, currency, font_size, deletion_requested_at

Every record collection except car_shares / organizations / control_audit carries one optional file attachment, served only through the API Server (GET /api/{records}/{id}/file) — never a public PocketBase URL.

Spreadsheet formulas (from the original Car Service.xlsx), reproduced by the API on read:

Next Service Date = service date + serviceIntervalDays   (Excel: =A+365)
Next Service Km   = service km   + serviceIntervalKm      (Excel: =B+15000)

These come back on each service record as nextServiceDate / nextServiceKm.

GET /api/cars returns the caller's owned cars plus any shared with them, each annotated with an access field. The per-record list endpoints also accept a ?car={id} filter (e.g. GET /api/service-records?car={id}).

Gotcha: updateCar rewrites all car columns from the payload, so a PATCH /api/cars/{id} must send the full car object — omitted spec fields get blanked. (The phone's odometer quick-edit sends the whole car for this reason.) The two exceptions are owner and the provider link (provider, provider_vehicle_id), which carPayload deliberately leaves out so an ordinary edit can neither reassign the car nor break its connected service.

Vehicle providers

internal/api/vehicleproviders.go turns a manufacturer-service plugin into a car you can create from your own account with that service, plus a per-car tab showing everything the service currently knows about it. Toyota (MyToyota) is the first provider; adding the next one means writing a vehicleSource adapter and appending it to vehicleSources() — no new endpoints and no Web App changes.

Two properties shape the design:

• Credentials are always the caller's. Every provider call resolves through the same global → org → user cascade as the integration settings, so a car shared with someone else shows them provider data only when that vehicle is on their manufacturer account. The owner's credentials are never borrowed.
• Upstream shapes are not modelled. These are unofficial APIs. Rather than hard-coding field paths, the layer searches payloads by key name for the handful of readings worth promoting (odometer, fuel, battery, range) and flattens the rest to dotted key/value pairs, shipping the raw payload alongside. A renamed field costs one blank value instead of a broken page.

POST .../import takes {vehicleId, name?, include?}, where include selects which groups to pull (identity, fuelType, dates, odometer). Omitting it means "everything available". POST /api/cars/{id}/provider/sync takes the same selection, and only ever moves the odometer forward — a reading that appears to go backwards is a stale provider, not a car driven in reverse.

The panel (/)

A Vue 3 + Tailwind app (source in panel/, built into internal/api/dist and embedded at compile time). It is the superadmin console:

• Overview — live health of the API Server, PocketBase and the Web App.
• Users / Organizations — full management, scoped to the caller's role.
• PocketBase — retarget the database connection at runtime; test before saving. Applied immediately and persisted to .env, so it survives a restart. This is the escape hatch when the configured PocketBase is wrong or unreachable — the settings endpoints deliberately do not require a working service account.
• Plugins — enable/disable/configure integrations, run health checks, register external plugins.
• API — the endpoint reference.

Log in with any DriverVault account; the sections you see depend on your role.

cd panel
npm install
npm run dev          # localhost:5174, proxies /api to localhost:8080
npm run build        # -> ../internal/api/dist   (then rebuild the Go binary)

Editing panel source alone does nothing to the served panel — run npm run build and then rebuild the Go binary, since dist is embedded.

Plugins

An extension system for integrating third-party services, managed by a superadmin. Two kinds share one contract: built-in (Go, compiled in) and external (any HTTP service, registered at runtime, no rebuild). Enable state and global config persist to PocketBase, in the app_settings singleton — the same place the per-org and per-user layers of the cascade live.

See internal/plugins/README.md for the full guide. Two built-in connectors ship today — Toyota Connected (toyota, read-only MyToyota vehicle data) and the Anker Solix V1 EV charger (anker-solix) — and any number of external HTTP plugins can be registered at runtime with no rebuild.

Integrations & charging control

Beyond the superadmin plugin registry, the built-in connectors are exposed per-user through /api/integrations/* under a superadmin → org admin → user cascade (each layer supplies defaults the next can override). For Anker Solix chargers the server additionally runs an OCPP 1.6J Central System (internal/ocpp): when the owner sets a control mode of own/proxy, the charger dials back in at GET /ocpp/{serial} (authenticated with OCPP Basic auth using a per-charger control token, not a bearer token) and the owner can start/stop and set charge limits, with every command rate-limited and written to a control_audit trail.

Configuration

Copy .env.example to .env and fill in. Summary:

Variable	Default	Purpose
API_ADDR	:8080	listen address (bare port accepted)
POCKETBASE_URL	http://10.2.1.10:8027	PocketBase base URL
POCKETBASE_ADMIN_EMAIL / _PASSWORD	—	superuser service account
CORS_ALLOW_ORIGINS	*	comma-separated browser origins
WEBAPP_URL	http://localhost:8090	probed by /api/status
AUTH_USERS_COLLECTION	users	PocketBase auth collection
PLUGINS_FILE	plugins.json	legacy plugin store, imported once then renamed
OCPP_REQUIRE_TLS	true	reject chargers that did not connect over TLS
OCPP_PUBLIC_URL	—	canonical ws(s):// base to point chargers at
PB_BOOTSTRAP	true	run the on-boot schema create/reconcile (leave on across upgrades)
DRIVERVAULT_SUPERADMIN_EMAIL / _PASSWORD / _NAME	— / — / Administrator	first superadmin, created on boot when absent

PB_URL, PB_ADMIN_EMAIL, PB_ADMIN_PASSWORD, PORT and CORS_ORIGINS are still honoured for older deployments; the modern names win when both are set.

Two paths are resolved relative to the working directory: the .env the panel rewrites when a superadmin retargets PocketBase, and PLUGINS_FILE (read once, to import a pre-PocketBase plugin store). In Docker the working directory is /data, a volume, so the .env survives a container recreate — see Dockerfile and ../Docker. Plugin settings no longer depend on that volume: they live in the database with everything else.

CORS_ALLOW_ORIGINS only matters for browser clients (the web app). Native mobile apps are not subject to CORS.

The service account is optional at startup: without it the server still runs and a superadmin can log in and configure it from the panel, while management endpoints return 503.

Scripts (scripts/)

node scripts/setup-pocketbase.mjs                    # create/reconcile collections (idempotent)
node scripts/create-user.mjs <email> <pw> "Name"     # create an app login
node scripts/set-role.mjs <email> user|admin|superadmin
node scripts/backfill-car-owners.mjs                 # one-off: assign owner to legacy cars
python scripts/seed_from_excel.py "C:/Users/jania/Desktop/Car Service.xlsx"

The Node scripts read POCKETBASE_URL / POCKETBASE_ADMIN_EMAIL / POCKETBASE_ADMIN_PASSWORD (or the legacy PB_* names) from the environment.

PocketBase note: collections created by the setup script do not get automatic created/updated autodate fields in this PocketBase version — sorting on created fails unless an explicit F.autodate(...) is added. When adding a new car spec field, extend DESIRED.cars in setup-pocketbase.mjs, add it to models.Car + the record mapping in records.go, then rebuild.

Startup bootstrap: the server also runs this same create/reconcile on boot (internal/bootstrap, a Go mirror of setup-pocketbase.mjs) whenever a service account is configured, so the Docker prod stack needs no manual setup step. It is idempotent and gated by PB_BOOTSTRAP (default true; set to false to skip). With DRIVERVAULT_SUPERADMIN_EMAIL + DRIVERVAULT_SUPERADMIN_PASSWORD set it also creates the first superadmin user when absent. Keep the two schemas in sync: a change to DESIRED in the script must be mirrored in internal/bootstrap/schema.go (guarded by TestSchemaConsistency).

First-time setup

1. Create the PocketBase collections (idempotent — safe to re-run on an existing deployment; it adds organizations, users.organization, and grows users.role to include superadmin):

   $env:POCKETBASE_URL="http://10.2.1.10:8027"
   $env:POCKETBASE_ADMIN_EMAIL="you@example.com"
   $env:POCKETBASE_ADMIN_PASSWORD="secret"
   node scripts/setup-pocketbase.mjs
   

2. Mint the first superadmin. The panel's management screens need one, and only a superadmin can promote another — so the first has to come from the script:

   node scripts/create-user.mjs admin@example.com "a-long-password" "Admin"
   node scripts/set-role.mjs admin@example.com superadmin
   

3. Run the server — go run ./cmd/server, or build and run the binary.

4. Open the panel at http://localhost:8080/ and sign in.

5. (Optional) Seed from the spreadsheet with the server running (see scripts).

Build & run

go build -o bin/api-server.exe ./cmd/server

The deployment runs the prebuilt binary bin/api-server.exe (not go run), started detached so it survives the shell:

Start-Process -FilePath ".\bin\api-server.exe" -WorkingDirectory "." `
  -WindowStyle Hidden -RedirectStandardOutput api-server.out.log `
  -RedirectStandardError api-server.err.log

Go's log package writes to stderr, so check api-server.err.log for request logs and errors. After editing any Go source, rebuild and restart the process — editing source alone does nothing until the binary is rebuilt.

Migrating from the JWT build

Earlier builds minted their own HS256 JWT and tracked a sessions collection for "active devices" / remote logout. That is gone — the server now relays PocketBase tokens. Consequences:

• AUTH_SECRET is obsolete and ignored.
• Login returns PocketBase's envelope — {token, record}, not {token, user}.
• GET|DELETE /api/sessions* are gone. PocketBase tokens are stateless, so there is nothing to revoke per-device. To lock every device out of an account, change its password: PocketBase rotates the user's token key, which invalidates every token already issued.
• User management moved from /api/admin/users* to /api/users*, and the separate password-reset endpoint folded into PATCH /api/users/{id} ({"password": "..."}). Responses are enveloped: {users} / {user}.
• Existing tokens are invalid — every client must log in once more.
• The sessions collection is left in PocketBase rather than dropped; delete it by hand if you want it gone.

The Web App and Phone App in this repo are already updated for all of the above.
