Cav

NOTE: This is new and probably broken somehow, don’t use it in production. (Unless you’re me lol)

Cav is an experimental full stack web framework for Deno. Here’s some notable features:

• Compatible with Zod parsers, enabling end-to-end type safety
• Serves static assets and serializes (nearly) any JavaScript type to JSON
• Web socket support
• Zero config (i.e. good defaults), and zero third-party dependencies
• Dev-time bundling for frontend TypeScript assets
• Compatible with frontend frameworks like Preact
• Deno Deploy without a build step

Inspirations

• Zod / tRPC
• Express / Koa / Oak
• superjson / devalue / json-dry
• Next.js / Aleph.js

Introduction

Cav requires Deno v1.21.2 or higher. If you’re new to Deno, read the manual to get up to speed.

A simple “hello world” app in Cav looks like this:

TODO: Start with the smallest hello world possible, introduce other features step by step, building it out into a full blown app
