Leptos on Workers

A template for using Leptos ssr + server functions in a Cloudflare worker.

Prerequisites

Install Rust from rustup.rs. Then:

cargo install cargo-leptos --locked

Wrangler

You'll need some version of Node.js. I personally recommend using nvm. Then:

npm install --global wrangler

Run locally

wrangler dev

Run on Cloudflare

wrangler deploy
