What is TS Plugin?

What does it do? Why should I enable it?

Since TypeScript cannot handle type information for .vue imports, they are shimmed to be a generic Vue component type by default. In most cases, this is fine if you don't really care about component prop types outside of templates. However, if you wish to get actual prop types in .vue imports (for example to get props validation when using manual h(...) calls), then you need to enable this plugin.
