I don't know much about Rollup sorry, let's ask @chimon2000 who contributed to this branch

[lumine]

This happened to me on the webpack build ERROR in my-vue-component.js from UglifyJs Unexpected token: punc (() UglifyJs did not seem to understand the ES2015 Enhanced Object Literal syntax. The second line where a method is declared. methods: { share ($event) { window.alert('Share on ' + $event.target.innerHTML); } I have node 8 and npm 5.5.1 I don't understand Babel well enough to figure it out yet. Maybe it needs a .babelrc file or an update to babel-preset-env.

I fixed this by adding a .babelrc file with the following content: { "presets": [ ["es2015", {"modules": false}] ] }

This was with the webpack build.

would you please send a PR ?

Just merged this commit to master and added .babelrc to branch rollup
