# Project Manager — web

Vue 3 + TypeScript + Vite PWA. Talks to the REST API in the parent directory.

## Develop

```bash
npm install
npm run dev            # http://localhost:5173
```

The dev server proxies `/api` to `http://localhost:8080` (the Dockerised API —
run `docker compose up -d` in the parent directory first). Override the target
with `VITE_PROXY_TARGET`, or point the app at a different API entirely with
`VITE_API_BASE_URL` (see [.env.example](.env.example)).

## Build

```bash
npm run build         # type-checks, then emits dist/
npm run preview
```

The parent `Dockerfile` runs this build in a Node stage and copies `dist/` into
the PHP image's `public/`, so the `app` container serves the compiled SPA at `/`.
There is no separate frontend container — a production image is `docker compose
build app` from the parent directory.

```

Signed-in "app" routes (`meta.requiresAuth`) render inside a persistent shell:
the top bar, then a left **sidebar** (`AppSidebar.vue`) beside the routed view.
The sidebar stays mounted across navigation — it holds a **Dashboard** link, a
divider, a project `<select>`, another divider, then the **Inbox** (see below).
The dropdown is a `v-model`-bound writable `computed` (`selectedProjectId`):
its getter reads the open project from `route.params.id`, so it tracks
whichever project is current; its setter `router.push`es to the chosen one, so
it also works as a project switcher from anywhere. `<RouterView
:key="route.path">` remounts the view on every path change so switching
projects always does a fresh load.

Below `768px` (`style.css`'s one layout breakpoint) the sidebar becomes an
off-canvas drawer instead of sitting beside the page: `position: fixed`,
translated out of view by default, slid in via a `.sidebar--open` class.
`App.vue` owns the `drawerOpen` state -- a `☰` button in the header (hidden
above the breakpoint) opens it; a backdrop tap, the drawer's own `✕` (which
`AppSidebar` emits `close` for), or any navigation (a `route.fullPath`
watcher) closes it. Above the breakpoint `drawerOpen` just goes unused, since
nothing renders the button that would set it.

`/` redirects to `/dashboard` (`DashboardView.vue`): a full-width grid linking
to each project (title + card count), with a **"Create a project" tile**
styled to match sitting last in the same grid (creating one stays on the
dashboard; the grid and the sidebar dropdown both pick it up via the shared
`projects` store). Signed-out routes
(`/login`, `/verify-email`) render without the sidebar.

## Styling

`style.css` is one global stylesheet (no scoped/component styles) with a
handful of conventions worth knowing before adding to it:

- **Tokens** (`:root` custom properties): colours (`--bg`, `--surface`,
  `--border`, `--text`, `--muted`, `--accent`(-text), `--error`, `--warn-bg`/
  `-border`), a border-radius scale (`--radius-sm` 6px compact controls,
  `--radius-md` 8px buttons/inputs, `--radius-lg` 10px tiles, `--radius-xl`
  12px panels, `--radius-pill`), and two opacity values (`--opacity-disabled`
  0.6, `--opacity-ghost` 0.5 for a dragged item's placeholder). Reach for one
  of these before hand-writing a value that's really just "the same grey
  border again" or "the same rounding as every other button."
- **`.field`** is the one themed `<input>`/`<textarea>`/`<select>` look, used
  everywhere from the login form to the sidebar's project switcher.
  `.field--compact` is the same thing smaller, for a control that's a flex
  child beside a button (an inline "add" row) or squeezed into the sidebar.
  `.field--autosize` adds the `resize:none; overflow:hidden` the dashboard's
  JS-driven auto-growing textarea needs. Crucially, **`.field` is applied
  directly to the control**, not to a wrapper (`.form input` no longer
  exists) -- see the next point for why that's load-bearing, not just style.
- **Put component classes on the control itself, not a wrapping element**,
  for anything that needs a `:focus` state. `input:focus`/`textarea:focus`/
  `select:focus` (global, removes the default outline and colours the border
  with `--accent` instead) has specificity `(0,0,1,1)` -- one pseudo-class,
  one element. A rule shaped `.wrapper input { border-color: var(--border) }`
  ties it exactly, and being unconditional, silently wins that tie by simply
  appearing later in the file -- the input keeps `var(--border)` forever,
  focused or not, no matter what `:focus` says. `.field`, applied straight to
  the element, is `(0,0,1,0)` -- strictly lower, so it can never win that
  tie regardless of source order. (This bit a real shipped version of the
  app: half the inputs had a working focus ring and half silently didn't,
  purely from which pattern each one happened to use.) A component that
  needs its own more elaborate `:focus` state (`.card-row__text`, background
  swap included) writes `.card-row__text:focus` explicitly -- specificity
  `(0,0,2,0)`, genuinely higher, wins outright rather than by luck of
  ordering.

## Inbox

A card with no project lives in the caller's inbox (`useInboxStore`), rendered
in the sidebar under the project list -- not per-project, and not tied to
whatever page is open. It's a `vuedraggable` list in the same `"kanban"` drag
group as every project's kanban columns (below), so a card can be dragged
straight out of the sidebar into any status column of whichever project is
currently open, or the other way. `AppSidebar`'s `onInboxChange` persists a
drop via `reorderColumn(null, null, ids)`, then reloads the inbox and, if a
project view is currently mounted (`route.name === 'project'`), that project's
cards too -- either side of a drag could have been the inbox. A small form
under the list adds a card straight to the inbox.

Empty (no cards) is shown as a subtle dashed drop-area rather than blank
space -- `.kanban__cards:empty` in `style.css`, so it's pure CSS keyed off the
real DOM child count. Since a card's kanban column/inbox `<draggable>` is
always rendered even with nothing in it (see above), that container is
genuinely childless when empty, so the rule applies with no extra markup or
JS state; it steps aside automatically once Sortable inserts its drag-over
ghost. The same rule covers every kanban status column too (below).

## Project detail

`/projects/:id` shows one project. `ProjectView.vue` is a **layout**, not a
page of its own: it renders on a **full-width** layout (the parent route sets
`meta.wide`, inherited by its children, which widens `.app__main` in
`App.vue`), loads the project and its cards, and renders the header + a small
sub-nav — its two children (below) render into its `<RouterView>`.

The header: a plain title heading, with an inline `.title-back` arrow to the
dashboard right before the text -- renaming lives on the configuration view
(below) -- and `ProjectManageMenu.vue` top right, with a **Configure** link
(to that view) and a **Delete project** action that opens a confirmation
modal; confirming calls `DELETE /api/projects/:id` and returns to the
dashboard.

The sub-nav (`RouterLink`s styled as tabs, active one matched on `route.name`)
is real navigation, not client-side tab state -- **Explore** is the project's
own route (`/projects/:id`, name `project`), **Kanban** a child beneath it
(`/projects/:id/kanban`, name `project-kanban`). Both read the `cards` store
the layout already loaded; App.vue's top-level `<RouterView>` key is derived
from the matched route's *top-level* path plus params rather than the full
path, so switching between them doesn't remount the layout (and re-fetch the
project) the way switching to a different project's id still does.

### Explore

The flat card list, **sorted by name (case-insensitive)** via a `sortedCards`
ref (rebuilt by a `watch` on the store's `cards.cards` -- a plain computed
can't be handed to `<draggable>`, which splices its bound list in place as
the user drags). Each row links to the card's own view (`/cards/:id` — see
[Card detail](#card-detail)); there is no manual order here, and no delete
button either -- deleting lives on that view now.

The list is a `<draggable>` too, but one-directional: `group: { name:
'kanban', put: false }` and `sort: false` mean a card can be dragged *out* --
to the sidebar's inbox, unfiling it from the project -- but Explore can't
receive a drop itself (there's no status to put an incoming card in), nor
reorder on its own drag (it's sorted by name regardless). No `@change`
handler is needed on this side: `<draggable>` already splices the card out of
`sortedCards` locally, and the inbox's own handler (see above) persists the
move and reloads this project's `cards`, which rebuilds the list from the
authoritative result regardless of which side reacted to the drop.

### Kanban

One column per project status, in `position` order -- the inbox is *not* a
column here; it's in the sidebar (see above), though it's still a valid drag
target as well as a source (unlike Explore, which can only send a card *to*
the inbox, not receive one). Unlike the cards, statuses are this route's own
fetch (`GET /api/projects/:id/statuses`) -- Explore has no use for them.
`board` is derived from `cards.cards` + those statuses and rebuilt by a
`watch` whenever either changes.

Every drop — whether reordering within a column (`moved`) or dragging in from
another column or the sidebar's inbox (`added`) — calls
`reorderColumn(projectId, column.statusId, ids)` from `lib/cardOrder.ts` (shared
with the sidebar) → `PUT /api/cards/order`. The server re-parents any moved-in
card and re-packs whatever column it left; afterwards the view always reloads
both `inbox` and this project's `cards`, since either could have been the other
side of the move.

## Project configuration

`/projects/:id/configure` (`ProjectConfigureView.vue`) manages a project's
statuses. The header mirrors the project view's — an inline `.title-back`
arrow before the title, this time back to the project, and
`ProjectManageMenu` top right (its own Configure link is hidden here, since
it would just point at the current page).

A **Rename project** section (a plain `PATCH /api/projects/:id` form,
`{ title }`) sits above **Statuses**. On success it also calls the
`projects` store's `fetchProjects()` -- the local `project` ref (and this
view's own header) update from the PATCH response directly, but the
dashboard grid and the sidebar's project dropdown read from that store, so
without the extra fetch the new name (and alphabetical position -- projects
are API-ordered by title) wouldn't show up there until some other reload.

The status list is a `vuedraggable` list (its own list, no shared drag group
with the kanban board) bound directly to a local `statuses` ref; dragging
mutates it in place, and `@change` persists the whole new order via
`PUT /api/projects/:id/statuses/order`, reverting to the server's copy on
failure. A small form below it adds a status
(`POST /api/projects/:id/statuses`) at the end of the list.

Each row has a delete button. A status with no cards deletes immediately; one
still holding cards gets `409` back from `DELETE .../statuses/:statusId` with
`error.details.card_count` (surfaced as `ApiError#cardCount`) -- that opens a
modal asking which other status to move its cards to, then resubmits the same
delete with `{ reassign_to }`, which reassigns and deletes in one request. The
last remaining status can't be deleted (a project card always needs one); its
row's delete button is disabled once `statuses.length <= 1`.

## Card detail

A card's text is no longer inline-editable anywhere it's listed -- the
Explore row, a kanban column, and the sidebar inbox all just link to
`/cards/:id` (`CardView.vue`) instead. Its header follows the same pattern as
every other view now: an inline `.title-back` arrow before the title text,
`Manage` in the actions corner. The arrow goes to the card's project, or the
dashboard for an inbox card (there's no standalone view of the inbox to
return to). Below the header sits just the status badge -- no tabs, since
there's nothing else to show for a single card.

`/cards/:id/configure` (`CardConfigureView.vue`) mirrors the project
configuration view once more: same header (its back arrow instead returns to
the card view), with a **Rename card** form below it (`PATCH /api/cards/:id`,
`{ text }`). `CardManageMenu.vue` -- the card equivalent of
`ProjectManageMenu.vue` -- provides both views' **Manage** menu: a
**Configure** link (hidden on the configure view itself) and a **Delete
card** action behind a confirmation modal.

Saving a rename or confirming a delete refreshes whichever store holds the
card -- the `cards` store (for a project card) or the `inbox` store -- so the
board or sidebar it came from picks up the change; deleting also navigates
back to wherever its back arrow points.

## Auth flow

There is no password and no separate sign-up — `LoginView` is an email field
and a "Send sign-in link" button (`POST /api/auth/magic-link`), for a new
address or a returning one alike. On success it shows a "check your email"
message; it does not sign the caller in itself. If the browser supports
WebAuthn, a **"Log in with a passkey"** button sits below the form, past a
divider (see [Passkeys](#passkeys)) — that one *does* sign the caller in
directly, no email round trip.

- `/verify-email?token=…` is the target for every magic link (sign-in and
  email-change confirmation both). `VerifyEmailView` POSTs the token via
  `auth.verifyEmail()`, which returns a session — opening the link is what
  actually signs the caller in — then redirects to the dashboard.
- The token is kept in `localStorage` and sent as `Authorization: Bearer …`.
  On load, `fetchMe()` validates it via `GET /api/me`; a failure clears it.
- Routes with `meta.requiresAuth` redirect to `/login` (preserving the intended
  path) when there is no authenticated user.
- Because the only way to get a session is opening a link or using a passkey
  (which itself requires a prior link-based sign-in to register), `user.
  email_verified` is always `true` for a signed-in user — the frontend doesn't
  show any verification nagging or resend UI.

## Passkeys

`src/lib/webauthn.ts` wraps the two ceremonies. Both fetch a `{ challenge_id,
options }` pair from the API, decode `options.publicKey`'s base64url fields
(`challenge`, `user.id`, `*Credentials[].id`) into `ArrayBuffer`s, call
`navigator.credentials.create()` / `.get()`, then base64url-encode the
resulting `PublicKeyCredential`'s response back into JSON for the API
(`{ id, response: { clientDataJSON, ... } }`). `passkeysSupported()` is a
one-line `window.PublicKeyCredential` check gating the UI everywhere below.

- **Register** (`ProfileView`, "Passkeys" section) — lists the caller's
  passkeys (`GET /api/passkeys`) with a **Remove** button each
  (`DELETE /api/passkeys/{id}`), and an "Add a passkey" form: a label input
  (pre-filled with a guess from `navigator.userAgent`, e.g. "Mac") and a
  button calling `registerPasskey(label)`. On success it appends to the local
  list and calls `auth.fetchMe()` so `user.has_passkey` (and the notice below)
  updates immediately.
- **Login** (`LoginView`) — the passkey button calls
  `auth.loginWithPasskey()`, which adopts the returned session exactly like
  `verifyEmail()`, then redirects to `route.query.redirect` or `/`. A
  cancelled prompt (`DOMException` named `NotAllowedError`) shows "Cancelled."
  rather than a generic error.
- **`PasskeyNotice.vue`** (mounted in `App.vue`, between the header and the
  sidebar/main body — spans the full page width) shows when signed in with
  `user.has_passkey === false`. Dismissing it writes
  `localStorage['passkeyNoticeDismissedUntil'] = Date.now() + 7 days`; the
  banner stays hidden until that passes, and reappears immediately (no reload
  needed, since `has_passkey` is reactive on the shared `auth.user`) if every
  passkey is later removed.

## Profile

`/profile` (`ProfileView`) sets `meta.wide` like the dashboard/project views,
rather than sitting in the default narrow column (that's now just the login
form). It shows the current address, the **Passkeys** section
described above, and a **Change email** form (new address only, no password).
On success the API has emailed a confirmation link to the *new* address and
set `user.pending_email` (shown as a notice until it's opened); the change
only lands once that link is opened. The button shows a live countdown driven
by `retry_after` and by `429` responses.
