Deno Fresh

Build fast web apps with Deno Fresh. Create islands of interactivity, server-rendered pages, API routes, and middleware using Deno's secure runtime with zero build step and just-in-time rendering.

This skill helps you build web applications with Fresh, Deno's full-stack framework. It generates islands for interactive components, server-rendered routes, API endpoints, middleware chains, and Preact components — with no build step, instant deploys to Deno Deploy, and TypeScript by default.

When to use

Use when building web apps on Deno, creating server-rendered sites with minimal client JavaScript, or when you want a secure-by-default runtime with built-in TypeScript and zero configuration.

Examples

Interactive dashboard

Build a server-rendered page with interactive islands

Create a Fresh dashboard page with a server-rendered data table and interactive chart island that updates in real-time without full page reloads

API with middleware

Build authenticated API routes

Set up Fresh API routes for a CRUD app with authentication middleware, CORS handling, and Deno KV for persistent storage
