Loco + Leptos SSR Showcase

[JonasCir]

Hi there,
I stumbled over leptos_axum which provides an easy way to setup Leptos SSR for Axum. I wondered how much work it would be to bring this to loco and it turns out, it is absolutely feasible. Let me show you:

1. Run loco new -> App name: loco_leptos_ssr -> lightweight-service to keep it simple
2. cargo install --locked cargo-leptos -> official Leptos tooling
3. rustup target add wasm32-unknown-unknown
4. git clone git@github.com:loco-rs/loco.git -> we need a minimal patch for loco
5. Patch loco with this small git diff gist. That's the only change needed for loco. Could be easily put behind a feature flag. Use git apply filename.patch.
6. Patch loco_leptos_ssr with this git diff gist. What I did here was to go through Leptos' official Axum template (licensed under "The Unlicense") and basically applying everything what they did there to the fresh project. Biggest part of the diff is due to them using the Cargo.toml for config and setting up dependencies/features/targets. The actual code changes are small. I also had to change the name of the bin (removed -cli as I was hitting a bug with cargo-leptos w.r.t. name normalization).
7. Drop your favorite favicon.ico into public and run cargo leptos watch -- start
8. Wait -> Two artifacts being build -> http[://]localhost[:]5150/
9. src/leptos_ssr/app.rs allows to seamlessly call server functions unlocking the true power of both projects :)
10. Profit

What do you think? :)
