[Vuejs]-Need to import non ES6 library without export to VueJS

Use eslint cli and run it with the --fix flag. This can fix a lot of these issues with the linter. https://eslint.org/docs/user-guide/migrating-from-jscs#–fix

Other than stylistic changes and es6 syntactic sugar, it will work just fine in the browser, so there’s no need to rewrite anything.
