# PHP Project Manager

A small project-management application: a REST API written in PHP (Slim 4)
backed by an SQLite file, plus a Vue 3 + TypeScript PWA frontend in [web/](web/).
Each user owns **projects**, and each project holds ordered **cards**.

## Status

| Stage | Scope | State |
|-------|-------|-------|
| 1 | Auth API — register, login, `GET /me` | ✅ done |
| 2 | Frontend shell — Vite PWA, auth-gated routing, register/login pages | ✅ done |
| 3 | Project + card CRUD API | ✅ done |
| 4 | Frontend projects view — project index + create form | ✅ done |
| 5 | Frontend project detail — cards UI with drag-and-drop reorder | ✅ done |
| 6 | Project view — inline title/description editing, delete via a Manage menu | ✅ done |
| 7 | Email verification (magic links) + profile page (resend, change email) | ✅ done |
| 8 | Passwordless login — magic-link by default, password login behind a toggle | ✅ done |
| 9 | Per-project card statuses ("To do" / "Doing" / "Done"); status chip, new cards start with none | ✅ done |
| 10 | Project view — full-width, tabbed: alphabetical "All tasks" list + "Kanban" board, per-column drag ordering | ✅ done |
| 11 | Persistent left sidebar (Dashboard link + project dropdown); dashboard = grid of project tiles + a "Create a project" tile | ✅ done |
| 12 | Passwordless-only auth — registration and password login removed; a magic link is the sole way in, and creates the account if needed | ✅ done |
| 13 | Global inbox — cards can have no project; moved into the sidebar, drag in/out of any project's kanban columns | ✅ done |
| 14 | New-project form moved to the dashboard; sidebar project list is now a switcher dropdown; Kanban is a project's default tab | ✅ done |
| 15 | Passkeys (WebAuthn) — register from the profile page, sign in with one instead of a magic link; a dismissible notice nudges users with none | ✅ done |
| 16 | Project configuration view — manage a project's statuses: add, drag to reorder, delete (reassigning any cards on it first) | ✅ done |

There is no password. Signing in is entering an email address and opening the
magic link sent to it — the same step creates the account the first time. See
[Auth](#auth).

## Run with Docker

The only requirement is Docker with the Compose plugin.

```bash
docker compose up -d
```

This runs a multi-stage build — a Node stage compiles the Vue frontend, then a
PHP 8.3 + Apache stage bakes in the PHP source and the built SPA — applies
migrations, and serves the whole app at <http://localhost:8080>: the SPA at `/`
(assets and all) and the REST API under `/api` (e.g.
`curl http://localhost:8080/api/health`). Unknown paths fall back to the SPA
shell for client-side routing.

- A **[Mailpit](https://mailpit.axllent.org/)** container (the maintained MailHog
  successor — one ~15 MB Go binary, messages kept in memory) also starts. The API
  sends all email to it; read it at <http://localhost:8025>. Set
  `MAIL_TRANSPORT=mail` or `=smtp` (with `MAIL_SMTP_*`) to send for real.
- The image is the artifact: PHP source and the compiled frontend are copied in
  at build time, not bind-mounted. Rebuild to pick up any code change:
  `docker compose up -d --build`. For iterating on the frontend, run the Vite
  dev server on the host instead (see [Frontend](#frontend)).
- The SQLite database and the generated JWT signing key live in the `storage`
  named volume, mounted at `/var/www/storage`, so they survive
  `docker compose restart` / `down` + `up`.
- `docker compose down -v` removes the volume and gives you a clean database.
- Override settings via the environment or a `.env` file in this directory
  (Compose substitutes `APP_DEBUG`, `JWT_SECRET`, `JWT_TTL` — see
  [docker-compose.yml](docker-compose.yml)).

## Run without Docker

Requires PHP 8.1+ with the `pdo_sqlite` and `mbstring` extensions, plus
[Composer](https://getcomposer.org/). On Fedora:

```bash
sudo dnf install php-cli php-pdo php-mbstring composer
```

### Setup

```bash
composer install
cp .env.example .env      # optional; sane defaults are used without it
composer migrate          # creates storage/database.sqlite and its tables
```

### Running

```bash
composer serve            # http://localhost:8080  (php -S localhost:8080 -t public)
```

Any web server can serve the API as long as the document root is `public/` and
unknown paths fall through to `public/index.php`. `public/.htaccess` also serves
a built frontend from `public/` (copy `web/dist/` there) and only falls back to
`index.php` for `/api` and when no `index.html` is present.

## Frontend

The Vue/TypeScript PWA lives in [web/](web/). The production build is compiled
into the Docker image and served from the `app` container at `/`. For frontend
development, run the Vite dev server on the host — with the API container running
(`docker compose up -d`):

```bash
cd web
npm install
npm run dev        # http://localhost:5173, proxies /api to localhost:8080
```

Unauthenticated visitors are redirected to `/login` — enter an email address
and open the link that arrives; there is no separate sign-up. See
[web/README.md](web/README.md).

## Configuration

All settings are optional environment variables (read from `.env` or the real
environment). See [.env.example](.env.example).

| Variable | Default | Purpose |
|----------|---------|---------|
| `APP_DEBUG` | `false` | Include exception details in error responses |
| `DATABASE_PATH` | `storage/database.sqlite` | SQLite file location |
| `JWT_SECRET` | auto-generated into `storage/secret.key` | Token signing key |
| `JWT_TTL` | `86400` | Token lifetime in seconds |
| `APP_ALLOW_REGISTRATION` | `true` | When `false`, a magic link is only ever sent to an existing address — an unknown one is silently ignored, so no new accounts get created |
| `MAGIC_LINK_RESEND_SECONDS` | `60` | Minimum gap before a magic link can be resent to the same address (sign-in or email-change). Docker Compose overrides this to `0`, so links resend immediately in development |
| `APP_URL` | `http://localhost:8080` | Base URL used to build magic links (`http://localhost:5173` for a host `npm run dev`) |
| `WEBAUTHN_RP_ID` | `APP_URL`'s host | Passkey relying party ID (domain). Must be `localhost` or a real domain over HTTPS — a LAN IP won't work |
| `WEBAUTHN_RP_NAME` | `Projects` | Passkey relying party display name, shown in the browser/OS prompt |
| `MAIL_TRANSPORT` | `mail` | `mail` (PHP `mail()`), `smtp`, or `log` (append to a file) |
| `MAIL_FROM` / `MAIL_FROM_NAME` | `no-reply@todo.test` / `Projects` | Envelope sender |
| `MAIL_LOG_PATH` | `storage/mail.log` | Where `log` transport writes |
| `MAIL_SMTP_HOST` / `_PORT` / `_USERNAME` / `_PASSWORD` / `_ENCRYPTION` | — / `587` / — / — / `tls` | Used only when `MAIL_TRANSPORT=smtp` |

Standalone, SMTP is opt-in and the API otherwise falls back to PHP's `mail()`.
Under Docker Compose the default is `MAIL_TRANSPORT=smtp` pointed at the bundled
Mailpit container (`mailpit:1025`, no auth/TLS); open <http://localhost:8025> to
read what was "sent".

## API

Base path: `/api`. All request and response bodies are JSON; send
`Content-Type: application/json`.

### `GET /api/health`

```json
{ "status": "ok" }
```

### Auth

There is no password and no separate registration endpoint. Entering an email
address and opening the link sent to it is the entire flow, for a brand-new
address and a returning one alike. A user can also register one or more
[passkeys](#passkeys) and use one instead, once signed in at least once.

| Method | Path | Auth | Purpose |
|--------|------|------|---------|
| `POST` | `/api/auth/magic-link` | — | email a one-time sign-in link, creating the account first if the address is new |
| `POST` | `/api/auth/verify-email` | — | consume the token: sign in, and (the first time) mark the address verified, or apply a pending email change |
| `POST` | `/api/auth/passkey/options` | — | a challenge for signing in with a passkey (see [Passkeys](#passkeys)) |
| `POST` | `/api/auth/passkey/verify` | — | verify a passkey response and sign in |
| `GET` | `/api/me` | ✔ | the current user |
| `POST` | `/api/email/change` | ✔ | request a **deferred** email change |

#### `POST /api/auth/magic-link`

Request: `{ "email": "ada@example.com" }`.

Emails a one-time sign-in link (`<APP_URL>/verify-email?token=…`, 15-minute
expiry) and always returns `202` with the same message. If the address has no
account yet, one is created (unverified) right here — that's the only "sign
up" there is — unless `APP_ALLOW_REGISTRATION=false`, in which case an unknown
address is silently ignored (still `202`, nothing sent) and only an address
that already has an account can sign in. A link is only actually (re-)sent if
this address hasn't been emailed one in the last 60 seconds. `422` if the
address is malformed.

```json
{ "message": "Check your email for a link to sign in." }
```

#### `POST /api/auth/verify-email`

Body: `{ "token": "..." }`. A missing/invalid, already-used, or expired token is
`400` (distinct messages). Success signs the caller in:

```json
{
  "user": {
    "id": 1,
    "email": "ada@example.com",
    "email_verified": true,
    "email_verified_at": "2026-09-03T12:00:00Z",
    "pending_email": null,
    "has_passkey": false,
    "created_at": "2026-09-03T12:00:00Z"
  },
  "token": "<jwt>",
  "expires_at": "2026-09-04T12:00:00+00:00"
}
```

Opening a link is the only way to obtain a session, so an authenticated request
is always for a verified address — `email_verified` is `true` from the first
token a user's browser ever holds.

#### `GET /api/me`

Requires `Authorization: Bearer <jwt>`. `200 OK`: the same `user` object shown
above. `pending_email` is the address a still-valid email-change link is
waiting on, or `null`. `401` if the header is missing, malformed, or the token
is invalid/expired.

#### `POST /api/email/change`

Requires `Authorization: Bearer <jwt>`. Body: `{ "email": "new@example.com" }`.
The address must be free (`409`) and different from the current one (`422`).
Throttled to **once per 60 seconds** (shared with `/api/auth/magic-link`'s
resend window, per user) — `429` with `error.details.retry_after` when too
soon. On success, `202` with `retry_after` and `pending_email`:

```json
{
  "message": "Confirmation email sent to the new address.",
  "pending_email": "new@example.com",
  "retry_after": 60
}
```

The change is **not applied until** the magic link sent to the new address is
opened — until then `GET /api/me` still shows the old address, with
`pending_email` set. Opening that link both changes the address and re-verifies
it, via the same `/api/auth/verify-email`.

### Passkeys

WebAuthn, via [lbuchs/webauthn](https://github.com/lbuchs/WebAuthn). A passkey
is always registered as a **discoverable, user-verified** credential, which is
what makes login usernameless: the browser prompts the signed-in device for
whichever passkey it has for this site, with no email typed first. There's no
attestation/provenance check (`'none'` format) — this only confirms "the same
device that registered", the standard trust model for a public site's own
users, not a fleet of company-issued security keys.

| Method | Path | Auth | Purpose |
|--------|------|------|---------|
| `GET` | `/api/passkeys` | ✔ | list the caller's passkeys |
| `POST` | `/api/passkeys/options` | ✔ | a registration challenge |
| `POST` | `/api/passkeys` | ✔ | verify the browser's response and store the credential |
| `DELETE` | `/api/passkeys/{id}` | ✔ | remove a passkey (`204`) |
| `POST` | `/api/auth/passkey/options` | — | a login challenge (no email — discoverable) |
| `POST` | `/api/auth/passkey/verify` | — | verify and sign in |

Both `.../options` endpoints return `{ "challenge_id": 1, "options": { "publicKey": {…} } }`
— `options.publicKey` is passed more or less directly to
[`navigator.credentials.create()`](https://developer.mozilla.org/en-US/docs/Web/API/CredentialsContainer/create)
/ [`.get()`](https://developer.mozilla.org/en-US/docs/Web/API/CredentialsContainer/get)
(binary fields travel as base64url strings; the frontend converts them —
see [web/README.md](web/README.md)). `challenge_id` identifies a **single-use**
challenge, good for 5 minutes, and must be sent back with the browser's
response:

- `POST /api/passkeys` body: `{ "challenge_id": 1, "credential": {…}, "label": "My laptop" }`.
  `credential` is `{ id, response: { clientDataJSON, attestationObject } }`
  (all base64url). `201` with the stored passkey
  (`{ id, label, created_at, last_used_at }` — never the credential id or
  public key) on success; `400` if the response doesn't check out, `409` if
  that credential is already registered.
- `POST /api/auth/passkey/verify` body: `{ "challenge_id": 1, "credential": {…} }`,
  where `credential` also carries `authenticatorData`, `signature`, and
  `userHandle`. Success returns the same `{ user, token, expires_at }` envelope
  as `/api/auth/verify-email`. `401` if the credential isn't recognised or the
  signature doesn't check out.

`user.has_passkey` (on every user object) is `true` once at least one is
registered — that's what the frontend's "add a passkey" notice keys off.

### Projects

All routes below require `Authorization: Bearer <jwt>`. A project belongs to one
owner (the creator); another user's project — or a missing one — always responds
`404`.

| Method | Path | Purpose |
|--------|------|---------|
| `GET` | `/api/projects` | the caller's projects, sorted A→Z by title |
| `POST` | `/api/projects` | create a project |
| `GET` | `/api/projects/{id}` | one project |
| `PATCH` | `/api/projects/{id}` | update `title` and/or `description` |
| `DELETE` | `/api/projects/{id}` | delete the project and its cards (`204`) |

`GET /api/projects` is always ordered alphabetically (case-insensitive) by
title; there is no other sort option. A user may own at most **100 projects** —
creating one beyond that responds `409`.

Create/update body: `title` (required on create, 1–255 chars), `description`
(optional, ≤ 2000 chars, defaults to `""`). `PATCH` needs at least one field.

Project representation:

```json
{
  "project": {
    "id": 1,
    "title": "Website relaunch",
    "description": "Q3",
    "owner_id": 1,
    "card_count": 3,
    "completed_count": 1,
    "created_at": "2026-09-03T12:00:00Z",
    "updated_at": "2026-09-03T12:00:00Z"
  }
}
```

`GET /api/projects` returns `{ "projects": [ … ] }`.

Creating a project also seeds it with three **statuses** — "To do", "Doing",
"Done" (see [Statuses](#statuses)).

### Cards

A card either sits in its owner's **inbox** (`project_id` and `status_id` both
`null`) or belongs to exactly one of their projects with a status in it (both
set) — enforced by a database CHECK constraint, never one without the other.
The inbox is global to the user, not per-project. Because a card may have no
project, single-card and ordering routes are addressed globally, by the card's
own id, rather than nested under a project:

| Method | Path | Purpose |
|--------|------|---------|
| `GET` | `/api/projects/{id}/cards` | a project's cards, grouped by status then `position` |
| `POST` | `/api/projects/{id}/cards` | add a card directly to the project (its first status) |
| `GET` | `/api/inbox/cards` | the caller's inbox |
| `POST` | `/api/inbox/cards` | add a card to the inbox |
| `GET` \| `PATCH` \| `DELETE` | `/api/cards/{cardId}` | one card, owner-scoped (`404` otherwise) |
| `PUT` | `/api/cards/order` | set the order/contents of one column |

Create body (either creation route): `text` (required, 1–1000 chars),
`complete` (optional bool, default `false`). `PATCH` accepts `text` and/or
`complete` only — moving a card is done via the order route below, not PATCH.

**Ordering.** `position` is a dense `0..n-1` rank *within a column* — the cards
that share an `(owner, project, status)`. The inbox is its own column, per
owner. `PUT /api/cards/order` sets one column's contents and order:

```json
{ "project_id": 5, "status_id": 12, "card_ids": [3, 1, 2] }
```

`project_id`/`status_id` are both `null` for the inbox, or both set to a
project owned by the caller and one of its statuses (`404`/`422` otherwise).
`card_ids` must be distinct cards owned by the caller and must include every
card already in the target column (`422` otherwise); it rewrites positions to
`0..n-1`. Any card in the list that wasn't already in that column is
re-parented into it — moving it from another project's status, or the inbox,
or vice versa — and the column it left is re-packed, all in one transaction.
Returns `{ "cards": [ … ] }` for the new column. This is what dragging a card
in the kanban board (or the sidebar's inbox) calls on every drop; moving a
card from one project to another is just two calls, via the inbox in between.

Card representation:

```json
{
  "card": {
    "id": 10,
    "project_id": 1,
    "text": "Design homepage",
    "complete": false,
    "position": 0,
    "status_id": 2,
    "status": { "id": 2, "name": "Doing" },
    "created_at": "2026-09-03T12:00:00Z",
    "updated_at": "2026-09-03T12:00:00Z"
  }
}
```

`project_id` and `status_id` are `null` together for an inbox card. `status` is
the embedded `{ id, name }` of the linked status, or `null`. `GET …/cards`
returns `{ "cards": [ … ] }`.

### Statuses

Every project has an ordered set of card statuses, created with the project:
"To do", "Doing", "Done". They are project-specific — each project owns its own
rows, managed from the project's **configuration** view (create, reorder,
delete). A project always keeps at least one status, since a project card must
have one; deleting the last one is rejected (`409`).

| Method | Path | Purpose |
|--------|------|---------|
| `GET` | `/api/projects/{id}/statuses` | the project's statuses, ordered by `position` |
| `POST` | `/api/projects/{id}/statuses` | add one at the end — `{ "name": "Blocked" }` |
| `PUT` | `/api/projects/{id}/statuses/order` | reorder — `{ "status_ids": [3, 1, 2] }`, every status once |
| `DELETE` | `/api/projects/{id}/statuses/{statusId}` | delete (see below) |

```json
{
  "statuses": [
    { "id": 1, "project_id": 1, "name": "To do", "position": 0 },
    { "id": 2, "project_id": 1, "name": "Doing", "position": 1 },
    { "id": 3, "project_id": 1, "name": "Done",  "position": 2 }
  ]
}
```

Requires `Authorization: Bearer <jwt>`; a project that is missing or not owned by
the caller responds `404`.

**Deleting a status that still has cards** fails with `409` and
`error.details.card_count` set, rather than silently orphaning them (a
referenced status can't be deleted at the database level either — the FK is
`ON DELETE RESTRICT`). Retry with `{ "reassign_to": <another status id> }` in
the same project; those cards are moved there and the status deleted, in one
transaction.

### Error shape

Every error response looks like:

```json
{ "error": { "message": "The submitted data was invalid.", "details": { "email": ["Email must be a valid address."] } } }
```

`details` is present only when relevant (e.g. validation).

## Try it

Signing in needs the link the API emails, so this pulls it back out of the
bundled Mailpit catcher (adjust if you've pointed `MAIL_TRANSPORT` elsewhere).
The API pretty-prints its JSON, so responses are piped through `tr -d ' \n'`
before grep (Mailpit's own JSON doesn't need that):

```bash
BASE=http://localhost:8080

curl -s -X POST $BASE/api/auth/magic-link \
  -H 'Content-Type: application/json' \
  -d '{"email":"ada@example.com"}'

MSG_ID=$(curl -s "http://localhost:8025/api/v1/messages?limit=1" | grep -o '"ID":"[^"]*"' | head -1 | cut -d'"' -f4)
LINK_TOKEN=$(curl -s "http://localhost:8025/api/v1/message/$MSG_ID" | grep -o 'token=[a-f0-9]*' | head -1 | cut -d= -f2)

TOKEN=$(curl -s -X POST $BASE/api/auth/verify-email \
  -H 'Content-Type: application/json' \
  -d "{\"token\":\"$LINK_TOKEN\"}" | tr -d ' \n' | grep -o '"token":"[^"]*"' | cut -d'"' -f4)

curl -s $BASE/api/me -H "Authorization: Bearer $TOKEN"

PROJECT=$(curl -s -X POST $BASE/api/projects \
  -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json' \
  -d '{"title":"Website relaunch","description":"Q3"}' \
  | tr -d ' \n' | grep -o '"id":[0-9]*' | head -1 | cut -d: -f2)

curl -s $BASE/api/projects/$PROJECT/statuses -H "Authorization: Bearer $TOKEN"

curl -s -X POST $BASE/api/projects/$PROJECT/cards \
  -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json' \
  -d '{"text":"Design homepage"}'

curl -s $BASE/api/projects/$PROJECT/cards -H "Authorization: Bearer $TOKEN"
```

## Provenance

This project was generated with [Claude Code](https://claude.com/claude-code).
