Deploy and Host bun-starter on Railway

Bun is an all-in-one JavaScript runtime and toolkit designed for speed. Built from scratch using Zig, it features a fast JavaScript/TypeScript runtime, bundler, test runner, and package manager that aims to replace Node.js with faster performance.

This is a starter template for Bun apps with a simple web server with routing capabilities and static file serving. It provides a minimal setup to build web applications using Bun's APIs, with core features like HTML imports, route handling, and static asset serving without external frameworks.

  }
})

The application showcases:

Direct HTML file imports as modules
Simple route definitions without frameworks
Static asset serving with styling
