View Webpacker config Rails 6 VueJS vue-loader 15.md

config/webpack/environment.js

const { environment } = require('@rails/webpacker')
const coffee = require('./loaders/coffee')
const vue = require('./loaders/vue')

environment.loaders.append('vue', vue)

  auto* hash = reinterpret_cast<ruby_hash_t*>(p);
