Hi!

Vue3 is now beta. I think Encore should support Vue2 and Vue 3... at least for awhile. The changes needed to make Webpack work with v3 are not that many:

  1. Make sure the user installs vue/compiler-sfc instead of vue-template-compiler
  2. require VueLoaderPlugin in a slightly different way
  3. Add a slightly different "alias" for vue

You can choose the version with a new version option to enableVue():

Encore.enableVueLoader(() => {}, {
    version: 3
});

Otherwise, it will configure itself correctly if you have vue2 or vue3 installed, or it will (finally) recommend the vue2 install instructions. When v3 comes out, we would change the default recommendation to be v3.

"vue": "^2.3.4",
"vue-loader": "^15.0.11",
"vue": "^3.0.0beta.9",
"vue-loader": "^16.0.0-alpha.1",

With ^2.3.4 || ^3.0.0beta.9, yarn ALWAYS prefers the stable version 2. So, I've added the -beta, -alpha versions only here so that they will install. Then in scripts/force-lowest-dependencies.js, I manually force vue2 and vue-loader 15. It's super hacky - would love if someone knows a way for me to use ^2.3.4 || ^3.0.0beta.9 but tell yarn to install the beta v3.

[Chore] Updating lock dependencies

This doesn't affect end-users. I'm doing this mostly to isolate what test "hash" changes are unique to Vue 3 in #746 and which are just from upgrading dependencies.

Commits
-------

03bbd97 removing node_modules cache on appveyor
2020aae bumping to 7.7.0 babel/core to support babel.config.json
bf7d18d forcing lock file on appveyor
e3deda8 updating test hashes after dependency update
f87806a updating dependencies
Problem is that if we say "2 || 3-beta" for vue, yarn always prefers 2 because
it's stable. So we have 3-beta in package.json only (and then it installs fine)
and force vue2 manually.
I'm not sure why this is happening, but we kind of need to trust that
Webpack will be putting files in the correct order

The re-ordering works around a vue-loader bug - which was just merged :) vuejs/vue-loader#1671

import { createApp } from 'vue';
import App from './App'

createApp(App).mount('#app');

vue2 code is pretty much compat with vue3, except for how you originally render the app. So I have v2 and v3 entry files.

#app {
margin-top: 40px;
}

Typescript in vue2 vs vue3 is different enough that I have 2 separate directories.

// useJsx and vue 3 are not currently supported by Encore
if (this.vueOptions.useJsx && this.vueOptions.version === 3) {
throw new Error('Setting both "useJsx: true" and "version: 3" for enableVueLoader() is not currently supported. Please use version: 2 or disable useJsx.');

It appears that the babel preset that enables this doesn't work yet - vuejs/jsx-vue2#106

New feature to force what version to show when we recommend something to the user. Causes yarn add vue@^2 to be output.

Works on both versions of vue-loader - we always should have done this ;)
