[Vuejs]-Webpack vue compiler in 1 file in .net mvc5 environment

You may want to try having a single entry point.
To do this have a JS file in which you use import or require what your application needs.

If you have multiple independent small Vue apps, I guess you’ll have to make multiple webpack configurations.

Edit: I highly recommend you use the Vue CLI to setup a basic project from their template and then digging into it to understand the Webpack setup and such. https://github.com/vuejs-templates/webpack/tree/develop/template.
