Symfony + Vue: Never loading Vue components?

Question

I'm popping Vue into a Symfony 4 project, and I've followed all the rules I can find. For some reason, I can not get any Vue components to show up - I can't even execute a console.log from my app.js folder.

Here's app.js:

var Vue = require('vue');
import App from './components/App'
console.log('testing')
new Vue({
    el: '#app',
    template: '<App/>',
    components: { App },
});

Here's webpack.config:

var Encore = require('@symfony/webpack-encore');

Encore // directory where compiled assets will be stored .setOutputPath('public/build/') // public path used by the web server to access the output path .setPublicPath('/build') // only needed for CDN's or sub-directory deploy //.setManifestKeyPrefix('build/')

/*
 * ENTRY CONFIG
 *
 * Add 1 entry for each "page" of your app
 * (including one that's included on every page - e.g. "app")
 *
 * Each entry will result in one JavaScript file (e.g. app.js)
 * and one CSS file (e.g. app.css) if you JavaScript imports CSS.
 */
.addEntry('app', './assets/js/app.js')
//.addEntry('page1', './assets/js/page1.js')
//.addEntry('page2', './assets/js/page2.js')

// will require an extra script tag for runtime.js
// but, you probably want this, unless you're building a single-page app
.enableSingleRuntimeChunk()

/*
 * FEATURE CONFIG
 *
 * Enable & configure other features below. For a full
 * list of features, see:
 * https://symfony.com/doc/current/frontend.html#adding-more-features
 */
.cleanupOutputBeforeBuild()
.enableBuildNotifications()
.enableSourceMaps(!Encore.isProduction())
// enables hashed filenames (e.g. app.abc123.css)
.enableVersioning(Encore.isProduction())

// enables Sass/SCSS support
// .enableSassLoader()
.enableSassLoader(function(options) {}, {
    resolveUrlLoader: false
})

// uncomment if you use TypeScript
//.enableTypeScriptLoader()

// uncomment if you're having problems with a jQuery plugin
.autoProvidejQuery()
.enableVueLoader()
;

module.exports = Encore.getWebpackConfig();

And here's my template:

            {% block content %}
             <div id="app"></div>
            {% endblock %}

Like I said, even when console.log directly from app.js it doesn't do anything in the console. I'm certain that the build is getting the app.js file, as in my sources I see app.####.js being loaded (hashed version) and it contains the code I've written.

Make sure you include {{ encore_entry_script_tags('app') }}, in your template.
