If you are using the runtime-only build, it seems like you will need to either provide a render function or incorporate the standalone build. At this stage, I assume you are in the process of setting everything up, so the next step would be to determine how you plan to structure your application.
In case you opt for blade templating, you must utilize the standalone build. Simply add an alias in your webpack config to include it (refer to: https://github.com/JeffreyWay/laravel-elixir-webpack-official):
resolve: {
alias: {
'vue$': 'vue/dist/vue.common.js'
}
}
Alternatively, if you are working with browserify, make sure to update your package.json as follows:
"browser": {
"vue": "vue/dist/vue.common"
}
Laravel 5.4 includes this functionality by default (using Laravel mix), but it appears that version 5.3 does not offer it.
For those interested in utilizing .vue files to build a Single Page Application (SPA), the runtime-only build can be used along with creating an App.vue file containing your layout and mounting it accordingly:
var Vue = require('vue');
var App = require('./components/App.vue');
const app = new Vue({
render: h => h(App)
}).$mount('#app');
