A modernized, high-performance port of Ghost's default theme [Casper 2.0](https://github.com/tryghost/casper) built on top of **Astro 7**.

This port replaces the original Jekyll setup (`jasper2`), offering incredibly fast builds, type-safe content validation, server-side pre-rendering, and client-side page load times.

## 🚀 Key Features

- **Astro 7 & TypeScript**: Full TypeScript configuration and strict schema validations.
- **Type-Safe Content Schema**: Powered by Astro Content Collections and Zod to validate posts, tags, and authors.
- **Modern Asset Pipeline**: Stylesheets are bundled, minified, and optimized via Vite out of the box.
- **Zero-Dependency Vanilla JS Interactivity**: Ported jQuery scripts (infinite scrolling, scroll progress bar, and floating headers) to clean, performant **Vanilla JS**, and replaced FitVids with a native, zero-JS **CSS aspect-ratio** solution.
- **100% SEO Compliance**: Automatic metadata, canonical URLs, Open Graph images, Twitter cards, and Schema.org JSON-LD data pre-rendered on the server.
- **Compliance Feeds**: Auto-generated Atom XML RSS feeds matching the original Jekyll feeds exactly (`/feed.xml`, `/tag/[tag]/feed.xml`, `/author/[author]/feed.xml`).
- **Disqus & Subscribe Forms**: Out-of-the-box toggleable Disqus comments and location-aware email newsletter subscription forms.

## 🛠️ Local Development

### 1. Installation
Install the project dependencies using `pnpm` (recommended) or `npm`:

```bash
pnpm install
# or
npm install
```

### 2. Development Server
Start the local hot-reloading development server:

```bash
pnpm run dev
# or
npm run dev

## ⚙️ Configuration & Integration

### 1. Algolia Search Setup

The theme includes a lightweight, pre-configured **Algolia InstantSearch** overlay. To configure search:

1. Create an index on [Algolia](https://www.algolia.com/).
2. Index your site posts. You can index them using Algolia's web crawler or upload your post list JSON feed.
3. Open [config.ts](file:///c:/Users/anton/Documents/Github/casper/src/config.ts) and add your Algolia credentials to the `SITE_CONFIG` object:
   ```typescript
   algolia: {
     applicationId: 'YOUR_APP_ID',
     indexName: 'YOUR_INDEX_NAME',
     searchOnlyApiKey: 'YOUR_SEARCH_ONLY_API_KEY',
   }
   ```
4. If the `algolia` configuration block is removed or undefined, the search icons and widget will automatically disable.

### 2. Decap CMS (Netlify CMS) Integration

A fully configured Decap CMS admin dashboard is built into the template under `public/admin/` to manage posts, authors, and tags directly from your browser.

#### Setup Instructions:
1. **Host on Netlify**: Connect your GitHub repository to Netlify.
2. **Enable Netlify Identity**:
   - Navigate to **Site Configuration** > **Identity** > **Enable Identity**.
   - Under **Identity** > **Registration preferences**, change registration from **Public** to **Invite only** to restrict access to yourself.
3. **Enable Git Gateway**:
   - Under **Identity** > **Services** > **Git Gateway**, click **Enable Git Gateway** to authorize repository read/write access.
4. **Log in**:
   - Send yourself an invite under the **Identity** tab in Netlify.
   - Click the validation link in the email, create your credentials, and visit `https://yourdomain.com/admin/` to log in and start writing!

## 🔄 Keeping Your Blog Updated

If you created your blog by **forking** or **cloning** this repository, you can pull upstream updates, fixes, and performance optimizations (like code refactoring or package upgrades) into your personal repository using Git.

### 1. Add Upstream Remote
Inside your local blog repository directory, link this template repository as an `upstream` remote:
```bash
git remote add upstream https://github.com/AntonyLeons/casper.git
```

### 2. Fetch and Merge Changes
To pull the latest template updates and merge them:
```bash
# Fetch changes from the template repo
git fetch upstream

# Merge upstream main branch into your current branch
git merge upstream/main
```
If you customized configurations (e.g., in `src/config.ts`) or added custom content, resolve any merge conflicts that arise, and then commit and push to your remote repository.
