# URL Manager

A URL management tool that helps you organize and access your links efficiently.

## Features

- Create and manage short links
- Template links with dynamic parameters
- Bookmark pages with automatic title and summary extraction
- Screenshot capture for bookmarked pages
- Advanced search capabilities
- REST API access
- In-process background task scheduling (APScheduler)
- Network security scanner (NetScan)

## Prerequisites

- Python 3.12+
- [uv](https://github.com/astral-sh/uv) — fast Python package manager
- [just](https://github.com/casey/just) — command runner (`brew install just`)
- Docker + Docker Compose (for containerised setup)

## Quick Start (Local)

```bash
# 1. Install dependencies and apply migrations
just install

# 2. Install Playwright browsers (for screenshot capture)
just install-browsers

# 3. Run the full stack (Django + Tailwind watcher)
just dev-all
```

The app will be available at **http://localhost:8000**

> Run `just` (no arguments) to see all available recipes.

## Usage

### Managing Links

1. Create a new link at `/create/`
2. Access a link at `http://localhost:8000/your-alias`
3. For template links use `{param, default=value}` syntax in the URL

### Managing Pages (Bookmarks)

1. Add a bookmark at `/ui/pages/new/` — title and summary are auto-extracted
2. Screenshots are captured automatically in the background
3. View all bookmarks at `/ui/pages/`

### X (Twitter) Bookmarks

The app includes an offline archive of X.com bookmarks. Export your bookmarks from X, then import them for full-text search, filtering, and browsing — no further API calls needed.

#### 1. Export bookmarks from X

Use [x-bookmarks-exporter](https://github.com/nickcam/x-bookmarks-exporter) to download your X bookmarks as JSON files:

```bash
# Install
git clone https://github.com/nickcam/x-bookmarks-exporter.git
cd x-bookmarks-exporter
npm install

# Configure — copy .env.example to .env and fill in your X credentials
cp .env.example .env

# Export (produces individual <tweet_id>.json files in data/bookmarks/)
npm run export
```

The exporter produces either:
- A directory of `<tweet_id>.json` files (one per bookmark), or
- A `bookmarks_index.json` file containing all bookmarks in a `{"bookmarks": [...]}` wrapper.

Both formats are supported.

#### 2. Import into URL Manager

**Via management command:**

```bash
# Import a directory of JSON files
just import-bookmarks data/bookmarks/

# Import an index file
just import-bookmarks data/bookmarks_index.json

# Import a single file
just import-bookmarks data/single_bookmark.json

# Wipe existing bookmarks first, then re-import
just import-bookmarks data/bookmarks/ --clear
```

The command reports `created`, `updated`, `unchanged`, and `skipped` counts. Re-importing the same data is safe — unchanged items are detected via content hash and skipped.

**Via REST API:**

```bash
# Bulk import (export-format payload)
curl -X POST http://localhost:8000/api/bookmarks/import/ \
  -H "Content-Type: application/json" \
  -d '{"bookmarks": [{...}, {...}]}'

# Bulk upsert (flat array, either format)
curl -X POST http://localhost:8000/api/bookmarks/bulk/ \
  -H "Content-Type: application/json" \
  -d '[{"tweet_id": "123", "text": "hello"}, ...]'
```

#### 3. Browse imported bookmarks

- **Web UI**: visit `/ui/bookmarks/` — filter by media type, search by text/author, view full details
- **API**: `GET /api/bookmarks/` with filters like `?q=search&has_video=true&author=screen_name`
- **API docs**: `/ui/api-docs/` (Bookmarks section)

#### Dedup behaviour

Each bookmark is keyed by `tweet_id`. On re-import:
- **New tweet_id** → created
- **Existing tweet_id, content changed** → updated (engagement counts, media, etc. refreshed)
- **Existing tweet_id, content identical** → `unchanged` (only `last_imported_at` bumped; no save/signal overhead)

### Network Scanner (NetScan)

Available at `/ui/netscan/`. Create a scan profile to automatically monitor your home network for security issues (router exposure, DNS, TLS certs, camera access).

### API

- List pages: `GET /api/pages/`
- Full API docs: `/ui/api-docs/`

## Architecture

```
core/         — Django project config, APScheduler setup
links/        — Main app: links, pages, tags, posts, collections
netscan/      — Network security scanner
templates/    — Base HTML templates
```

Background tasks (screenshot capture, page metadata extraction, network scans) run via **APScheduler** in-process — no separate worker or Redis needed.

## Dependencies

Managed with `uv` via `pyproject.toml`.

```bash
# Add a new package
uv add package-name

# Sync environment from lockfile
uv sync
```
