Deploy Leptos CSR Apps on Spin

After installing both the Spin framework and Leptos, then clone this repo and run trunk watch in one terminal while also running spin watch in another terminal -- when making changes in your Leptos app, the only thing you need to do is reload the browser window: Leptos and Spin will take care of the rest!

For building and releasing the app, run trunk build --release and spin deploy to get your app up and running in the cloud!

If you'd like to deploy an existing Leptos CSR app to Spin:

1. Ensure you have the Spin CLI installed
2. in your CLI, move to the directory that contains your existing Leptos CSR app - for example purposes, we'll call this project directory "leptos-csr"
3. set up a new Spin project by using spin new
4. in the spin new CLI prompt, select the "static-fileserver" option
5. When the spin new CLI prompts you to provide a name for your application, provide the directory name of your existing project, eg. leptos-csr
6. Confirm that you want to generate the Spin project even though your direcotry already contains other files
7. Add a description for your project
8. for the HTTP path, use / instead of the default (/static/...)
9. for the directory containing the files to serve, enter dist (which is where the Leptos CSR app will automatically output your files when you run trunk watch or trunk build --release)
10. enter your directory and start developing with trunk watch & spin watch in separate terminals
11. to build and deploy your app, run trunk build --release, then spin deploy
12. Profit!

Optionally, you can add a build command to your spin.toml manifest file to automatically build Leptos for deployment just using the spin build & spin deploy commands. For example, if your project is named "leptos-csr", then include the following somewhere in your spin.toml file:

[component.leptos-csr.build]
command = "trunk build --release"

Further info about developing with Spin can be found in their excellent documentation.
