Add optional `ssg` feature to template

[ActuallyHappening]

I want to use an external tool Tauri along with Leptos, and find it necessary to use trunk serve and trunk build for this purpose. However, I had to manually add the logic on top of the starter template, which explicitly said: no client-side main function unless we want this to work with Trunk.

I believe that adding this feature will be helpful to those who are trying to mix cargo Leptos serve and trunk serve together

Are you just saying that you want to be able to run the same app either hosting on a server with server-side rendering or in Tauri with client-side rendering, and use the same template?

Or do you only want to use it with client-side rendering with Tauri?

If it's just client-side rendering, I'd suggest that creating a client-side-only template is a better idea, except that setting Leptos up with Trunk is so straightforward we haven't created a template yet.

If it's to switch between client-side rendering and server-side rendering, then I'd suggest using csr instead of ssg. What the ssg feature does here is not static site generation and could be confusing for people.

Well, the only way to produce a static site integrating Leptos is with the csr feature. If changing the PR's feature name to csr instead of the current ssg helps other understand how to make a static site as well as a ssr app with Leptos I'll change it

I'm still curious about the answer to the main question though:

Or do you only want to use it with client-side rendering with Tauri?

If it's just client-side rendering, I'd suggest that creating a client-side-only template is a better idea, except that setting Leptos up with Trunk is so straightforward we haven't created a template yet.

If you don't want the server side at all, I think creating a separate template that doesn't have the unneeded complexity is a better idea.

For context, I am using Tauri and leptos to create a cross-platform app + ssr website. I don't strictly need the ssr feature but I wanted to see if it was possible. Template for such a project: https://github.com/ActuallyHappening/start-leptos-tauri When I cloned the official leptos starter project and read the comments 'no client-side only main function, will need to implement this for use with trunk' I thought it best to actually provide a base implementation for others to see instead of needing to do that themselves

• In my tauri-leptos template, I have also set up bundling sass which I haven't added here (because that would require adding an index.html which would be quite confusing since the index.html file is only used locally by trunk)

Sounds good. Merged, and thanks.
