Example of vue-server-renderer usage

app.js

const serverRenderer = require('vue-server-renderer')
const fs = require('fs')
const path = require('path')

// Don't need to create Vue components for MJML ones
Vue.config.ignoredElements = ['mjml', /^mj-/]

// Create a Vue instance
const app = new Vue({
  template: fs.readFileSync(path.resolve('./mjml.vue'), 'utf8'),
  data() {
    return { ... }
  },
})

// Render Vue to HTML
// https://ssr.vuejs.org/guide/#rendering-a-vue-instance
const renderer = serverRenderer.createRenderer()
renderer.renderToString(app, (err, mjml) => {
  // Let's go
})
