Built a complete discussion forum using Bun's native HTTP server and SQLite database with server-side rendered HTML.

Implementation

  • Database layer (database.ts): Type-safe SQLite functions for posts and comments with foreign key relationships
  • Server (index.ts): HTTP routes for CRUD operations on posts and comments, form handling with proper validation
  • Templates (templates.ts): Server-side HTML generation with embedded CSS, XSS protection via HTML escaping

Architecture

No build step required. Server-side rendering eliminates client JavaScript. Form submissions use standard HTTP POST with 303 redirects. Database operations use Bun's native SQLite bindings.

Security

  • Input validation with type guards before database operations
  • HTML escaping for all user-generated content
  • Path parameter validation with NaN checks
  • CodeQL scan: 0 vulnerabilities

UI

Purple gradient background with card-based layout. Smooth transitions and hover effects. Fully responsive without media queries.
