Watch for file changes to support hotreload

[MJRasicci]

The Tailwind CLI supports a flag --watch which will rebuild tailwind any time one of the configured source files changes, We should run the CLI in watch mode to support hotreload scenarios. This will require managing the lifetime of the tailwind cli process more closely.

Any updates on this issue? :)

This would be a really helpful feature. What's left to do to make this work?

I had create an similar pack toolset for tailwindcss: Tailwind Hosting
This contains 2 main packages, one for Hosting Startup and other for MsBuild.
Check the examples/Blazor for how can use it.

But is simple, just dotnet add Tailwind.Hosting and dotnet add Tailwind.Hosting.Build
Then add the following to your Properties/launchSettings.json

"environmentVariables": {
    "ASPNETCORE_ENVIRONMENT": "Development",
    "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "Tailwind.Hosting"
}

My Tailwind.Hosting.Build implementation has less features and customizations than Tailwind.MSBuild package but works for integrate tailwindcss with .Net.

The available variables are:

Property	Value
TailwindVersion	latest or custom value like 3.3.5
TailwindWatch	true
TailwindInputCssFile	{Project Folder}/wwwroot/styles.css
TailwindOutputCssFile	{Project Folder}/wwwroot/app.css
TailwindConfigFile	{Project Folder}/tailwind.config.js
