Getting Started with Zerho

Quick start guide to create and deploy technical documentation in Deno.

Getting Started with Zerho #

Zerho is a pro-grade static documentation engine built natively for Deno 2 and optimized for instant global edge deployment on Deno Deploy.

Inspired by the ergonomics of modern documentation systems, Zerho eliminates legacy Node.js toolchains:

  1. Pure Deno 2 Runtime: Zero node_modules, zero npm baggage.
  2. Integrated Interactive Playground: Execute TypeScript/JavaScript directly within documentation pages.
  3. Instant Cmd+K Search: Client-side full-text index built during SSG.
  4. Synchronized Polyglot Code-Groups: Automatic tab switching with localStorage memory across the entire site.
  5. Native Mermaid Diagrams & OpenAPI Explorer: Diagramming and interactive REST explorer out of the box.

Quick Start #

To launch a Zerho project on your machine, you only need Deno installed:

# 1. Start development server with Live-Reload
deno task dev


# 2. Build static production bundle
deno task build


# 3. Preview production server with Edge Deno KV
deno task serve

LIVE

RELOAD (HMR) The deno task dev command starts a WebSocket file watcher that instantly reloads your browser whenever Markdown or config files change.

Interactive Live Demo #

Try the interactive Deno sandbox below. Click Ejecutar en Deno to execute the TypeScript snippet:

Deno Sandbox 
interface RuntimeInfo {
  engine: string;
  version: string;
  features: string[];
}

const info: RuntimeInfo = {
  engine: "Zerho Edge",
  version: Deno.version.deno,
  features: ["Web Workers", "WebCrypto", "Edge KV", "Native LLM Context"],
};

console.log("⚡ Zerho runtime successfully initialized:");
console.log(JSON.stringify(info, null, 2));
