# Paste

A minimal pastebin web app built on [CAN Service](../../). Type text and press Enter, or paste an image from your clipboard. Everything gets stored as a CAN asset.

## Features

- **Text paste** -- type and hit Enter to store a text snippet
- **Image paste** -- Ctrl+V an image from your clipboard, or click the paperclip to attach a file
- **Auto-tagging** -- use `#hashtags` in your text and they're extracted as CAN tags
- **Live refresh** -- new pastes appear instantly via Server-Sent Events (including content arriving from P2P sync on another machine)

## Running

Make sure CAN Service is running on port 3210 first:

```bash
# From the repo root
cargo run
```

Then start Paste:

```bash
cd examples/paste
cargo run
```

Opens automatically at [http://127.0.0.1:3211](http://127.0.0.1:3211).

## How It Works

Paste is a thin proxy layer. The Rust backend serves a single-page HTML/JS frontend and forwards requests to the CAN Service API:

| Paste Route | Proxies To | Purpose |
|-------------|-----------|---------|
| `POST /paste/text` | `POST /api/v1/can/0/ingest` | Store text as a `.txt` asset |
| `POST /paste/file` | `POST /api/v1/can/0/ingest` | Store an uploaded file |
| `GET /paste/list` | `GET /api/v1/can/0/list?application=paste` | List paste assets |
| `GET /paste/asset/{hash}` | `GET /api/v1/can/0/asset/{hash}` | Download an asset |
| `GET /paste/thumb/{hash}` | `GET /api/v1/can/0/asset/{hash}/thumb/200/200` | Image thumbnail |
| `GET /paste/events` | `GET /api/v1/can/0/events` | SSE stream for live updates |

All pastes are tagged with `application=paste` so they're scoped separately from other CAN content.
