deno is drinking fresh lemon squash

The next-gen web framework.

Fresh is a next generation web framework, built for speed, reliability, and simplicity. Some stand out features:

Just-in-time rendering on the edge.
Island based client hydration for maximum interactivity.
Zero runtime overhead: no JS is shipped to the client by default.
No build step.
No configuration necessary.
TypeScript support out of the box.

Fresh embraces the tried and true design of server side rendering and progressive enhancement on the client side.

Getting started

To get started, make sure you have the Deno CLI version 1.23.0 or higher installed.

Then you can use the Fresh init script to bootstrap a new project:

deno run -A -r https://fresh.deno.dev my-app

Enter the newly created project directory and run the following command to start the development server:

deno task start

You can now open http://localhost:8000 in your browser to view the page.

A more in-depth getting started guide is available in the docs.

Example

This text is being server side rendered on the fly. It was rendered at 18:43:40 UTC.

The counter below was rendered on the server with a starting value of 3, and was then hydrated on the client to provide interactivity. Try out the buttons!

3

Only the JS required to render that counter is sent to the client.
