What are you doing that causes you to need several files for a single component? I am working on a multi-page app using the TypeScript class decorators and .vue component files. I turned off most of the optional features (including babel), and it's just a single .vue file most most components. I configured the Webpack and TypeScript settings when I created the project and haven't had to do much since. I've used Vue on several other projects and have enjoyed using it every time. I like that parts of the Vue framework are optional. Don't want the router or state management? Don't use it. The codebase is well organized, the output files are small and the app is performant. I don't like all the dev dependencies you need to get going, but I have that same complaint about most other modern front-end frameworks.
