| 130 | +### Key Dependencies & Data Flow |
| 131 | + |
| 132 | +**Data Sources → Processing Pipeline:** |
| 133 | +1. **Markdown Files** (`/data/blog/*.md`) contain blog posts with frontmatter metadata |
| 134 | +2. **File System** operations read these files using Node.js `fs/promises` |
| 135 | +3. **Gray Matter** parses frontmatter (title, date, author, tags, excerpt) |
| 136 | +4. **Marked** converts markdown content to HTML with custom renderer |
| 137 | +5. **Posts Library** (`lib/posts.server.ts`) orchestrates the entire data processing pipeline |
| 138 | + |
| 139 | +**Server-Side Rendering Flow:** |
| 140 | +1. **Page Component** (`app/page.tsx`) fetches posts using `getBlogPosts()` |
| 141 | +2. **Server Components** render initial HTML with post data |
| 142 | +3. **Client Components** hydrate for interactivity (blog list, theme switching) |
| 143 | + |
| 144 | +**State Management Architecture:** |
| 145 | +1. **TextSizeProvider** manages font size preferences via React Context |
| 146 | +2. **ThemeProvider** handles light/dark theme switching |
| 147 | +3. **localStorage** persists user preferences across sessions |
| 148 | +4. **Context Consumers** throughout the app access and update these states |
| 149 | + |
| 150 | +**UI Component Architecture:** |
| 151 | +1. **Radix UI** provides headless, accessible component primitives |
| 152 | +2. **Custom Components** compose these primitives with Tailwind styling |
| 153 | +3. **Terminal-themed Design** creates a unique developer-focused aesthetic |
| 154 | + |
| 155 | +**Build & Deployment:** |
| 156 | +1. **Next.js** handles SSR, static generation, and optimization |
| 157 | +2. **GitHub Actions** automates build and deployment to Vercel |
| 158 | +3. **Vercel Analytics** provides usage insights |
| 159 | + |
| 160 | +This architecture creates a modern, performant blog platform with excellent developer experience, accessibility, and user customization options. |
