# PHP Todo List

A small todo-list application: a REST API written in PHP (Slim 4) backed by an
SQLite file, plus a single-page frontend (added in a later stage).

## Status

| Stage | Scope | State |
|-------|-------|-------|
| 1 | Auth API — register, login, `GET /me` | ✅ done |
| 2 | Todo CRUD API | planned |
| 3 | Single-page frontend | planned |

## 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`).

- 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`.

## 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 |

## 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", "created_at": "2026-09-03T12:00:00Z" },
  "token": "<jwt>",
  "expires_at": "2026-09-04T12:00:00+00:00"
}
```

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", "created_at": "2026-09-03T12:00:00Z" } }
```

`401` if the header is missing, malformed, or the token is invalid/expired.

### 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"
```

## Tests

```bash
composer install         # installs phpunit (require-dev)
vendor/bin/phpunit
```
