We recommend using Femto so Nuget and NPM dependencies are installed automatically.
Fable.Lit packages require fable 3.6 dotnet tool and Lit 2 from npm.
In the directory of your .fsproj, install the packages you need. Note the package ids are prefixed by
Fable. but not the actual namespaces.
dotnet femto install Fable.Lit dotnet femto install Fable.Lit.Elmish dotnet femto install Fable.Lit.Test
To get up-to-speed faster you can just clone Lit.TodoMVC, which already includes HTML templates, hook components, hot reloading and testing, and use it as the base for your app.
