A few weeks ago I’ve created an issue around Webpack 2 support for SPFx build pipeline. And there are some good reasons why it’s a good idea to use webpack 2 in SPFx:

• webpack 1 is deprecated
• documentation for webpack 2 is better
• webpack 2 schema more understandable
• sometimes webpack 2 faster (it depends, but still)
• all core webpack loaders supports version 2 and might have issues with previous version down the road
• SPFx introduced as a framework which supports modern web technologies and tools. Someone use Angular, React, someone Vue.js. Vue.js uses webpack 2 and it’s more natural to use webpack 2 with Vue when building SPFx web parts

Finally a few days ago SPFx team released a new version which built with webpack 2! And that’s a good news.

I had to fix all samples around Vue.js and SPFx, because webpack schema is changed. But now I personally feels more comfortable about extending SPFx with Vue.js, because at least they are using the same version of bundler.

Please checkout updated samples with Vue.js in official repository here - https://github.com/SharePoint/sp-dev-fx-webparts/tree/master/samples/vuejs-todo-single-file-component and experimental sample where everything in .vue file (including TypeScript code) - https://github.com/s-KaiNet/spfx-vue-sfc-one-file
