# PHP Todo List

A small todo-list application: a REST API written in PHP (Slim 4) backed by an
SQLite file, plus a Vue 3 + TypeScript PWA frontend in [web/](web/).

## 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 | Todo list + item CRUD API | ✅ done |
| 4 | Frontend lists view — list index + create form | ✅ done |
| 5 | Frontend list detail — items UI with drag-and-drop reorder | ✅ done |
| 6 | List view — inline title/description editing, delete via a Manage menu | ✅ done |
| 7 | Email verification (magic links) + profile page (resend, change email) | ✅ done |

Registration signs the user in immediately and emails a magic link that verifies
the address; `user.email_verified` stays `false` until the link is opened. See
[Email verification](#email-verification--profile).

## Run with Docker

The only requirement is Docker with the Compose plugin.

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

This builds a PHP 8.3 + Apache image, applies migrations, and serves the API at
<http://localhost:8080> (e.g. `curl http://localhost:8080/api/health`).

- 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 project directory is bind-mounted into the container, so editing PHP
  source takes effect without a rebuild (within ~2s, due to the opcache
  revalidation interval). `vendor/` is used from the host — run `composer`
  once first if it is missing (see "Run without Docker" below, or
  `docker compose run --rm --entrypoint composer app install`).
- The SQLite database and the generated JWT signing key live in the `storage`
  named volume, mounted at `/var/www/storage` (outside the bind-mounted source),
  so they survive `docker compose restart` / `down` + `up`.
- Rebuild only after changing the `Dockerfile`: `docker compose up -d --build`.
- `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 app as long as the document root is `public/` and
unknown paths fall through to `public/index.php`.

## Frontend

The Vue/TypeScript PWA lives in [web/](web/) and talks to this API. With the API
running (`docker compose up -d`):

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

Or run it inside Compose alongside the API:

```bash
docker compose --profile frontend up -d
```

Unauthenticated visitors are redirected to `/login`; `/register` creates an
account and signs in immediately. 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_URL` | `http://localhost:5173` | Frontend base URL used to build magic links |
| `MAIL_TRANSPORT` | `mail` | `mail` (PHP `mail()`), `smtp`, or `log` (append to a file) |
| `MAIL_FROM` / `MAIL_FROM_NAME` | `no-reply@todo.test` / `Todo List` | 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" }
```

### `POST /api/auth/register`

Request:

```json
{ "email": "ada@example.com", "password": "correct horse battery staple" }
```

`201 Created`:

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

New accounts are created with an unverified email (`email_verified: false`).

Errors: `422` invalid input, `409` email already registered.

Validation: `email` must be a valid address (≤ 255 chars); `password` must be
8–72 characters.

### `POST /api/auth/login`

Request:

```json
{ "email": "ada@example.com", "password": "correct horse battery staple" }
```

`200 OK`: same shape as register. `401` on bad credentials (the message does not
say whether it was the email or the password that was wrong).

### `GET /api/me`

Requires `Authorization: Bearer <jwt>`.

`200 OK`:

```json
{
  "user": {
    "id": 1,
    "email": "ada@example.com",
    "email_verified": false,
    "email_verified_at": null,
    "pending_email": null,
    "created_at": "2026-09-03T12:00:00Z"
  }
}
```

`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.

### Email verification & profile

Registration emails a magic link — `<APP_URL>/verify-email?token=<opaque>` — that
expires **15 minutes** after it is sent. Only a hash of the token is stored.

| Method | Path | Auth | Purpose |
|--------|------|------|---------|
| `POST` | `/api/auth/verify-email` | — | consume a token: verify the address (or apply a pending change), then return a session so the caller is logged in |
| `POST` | `/api/email/verification` | ✔ | resend the verification email; `409` if already verified |
| `POST` | `/api/email/change` | ✔ | request a **deferred** email change |

`POST /api/auth/verify-email` body: `{ "token": "..." }`. Success returns the
same `{ user, token, expires_at }` envelope as login. A missing/invalid, already
used, or expired token is `400` (distinct messages).

`POST /api/email/verification` and `/api/email/change` are throttled to **once
per 60 seconds** per user (shared window). When throttled they return `429` with
`error.details.retry_after` (seconds). On success they return `202` with
`retry_after`, and `/api/email/change` also returns `pending_email`.

`POST /api/email/change` body: `{ "email": "new@example.com", "password": "<current>" }`.
The current password is required (`422` if wrong). The address must be free
(`409`) and different from the current one (`422`). The change is **not applied
until** the magic link sent to the new address is opened — until then `GET
/api/me` shows the old address with `pending_email` set.

### Todo lists

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

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

`GET /api/lists` is always ordered alphabetically (case-insensitive) by title;
there is no other sort option. A user may own at most **100 lists** — 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.

List representation:

```json
{
  "list": {
    "id": 1,
    "title": "Shopping",
    "description": "For the week",
    "owner_id": 1,
    "item_count": 3,
    "completed_count": 1,
    "created_at": "2026-09-03T12:00:00Z",
    "updated_at": "2026-09-03T12:00:00Z"
  }
}
```

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

### Todo items

Scoped to a list; the parent list's ownership is checked first (`404` otherwise).

| Method | Path | Purpose |
|--------|------|---------|
| `GET` | `/api/lists/{id}/items` | items, ordered by `position` then `id` |
| `POST` | `/api/lists/{id}/items` | add an item |
| `PUT` | `/api/lists/{id}/items/order` | reorder all items in one shot |
| `GET` | `/api/lists/{id}/items/{itemId}` | one item |
| `PATCH` | `/api/lists/{id}/items/{itemId}` | update `text`, `complete`, and/or `position` |
| `DELETE` | `/api/lists/{id}/items/{itemId}` | delete the item (`204`) |

Create body: `text` (required, 1–1000 chars), `complete` (optional bool,
default `false`), `position` (optional integer ≥ 0; when omitted the item is
appended after the current highest position). `PATCH` needs at least one field.
`position` is a plain sort key the client manages — updating one item never
renumbers its siblings.

`PUT …/items/order` takes `{ "item_ids": [3, 1, 2] }` — every item in the list,
each exactly once (`422` otherwise). It rewrites positions to `0..n-1` in one
transaction and returns `{ "items": [ … ] }` in the new order. This is what the
drag-and-drop reorder in the UI calls.

Item representation:

```json
{
  "item": {
    "id": 10,
    "list_id": 1,
    "text": "Milk",
    "complete": false,
    "position": 0,
    "created_at": "2026-09-03T12:00:00Z",
    "updated_at": "2026-09-03T12:00:00Z"
  }
}
```

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

### 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

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

curl -s -X POST $BASE/api/auth/register \
  -H 'Content-Type: application/json' \
  -d '{"email":"ada@example.com","password":"password123"}'

TOKEN=$(curl -s -X POST $BASE/api/auth/login \
  -H 'Content-Type: application/json' \
  -d '{"email":"ada@example.com","password":"password123"}' | grep -o '"token":"[^"]*"' | cut -d'"' -f4)

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

LIST=$(curl -s -X POST $BASE/api/lists \
  -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json' \
  -d '{"title":"Shopping","description":"For the week"}' \
  | grep -o '"id":[0-9]*' | head -1 | cut -d: -f2)

curl -s -X POST $BASE/api/lists/$LIST/items \
  -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json' \
  -d '{"text":"Milk"}'

curl -s $BASE/api/lists/$LIST/items -H "Authorization: Bearer $TOKEN"
```
