Flexivue

Integrate Vue.js with Rails views and webpacker.

Flexivue is a flexible tool to use Vue with Rails. The benefits:

• Lets you both use Rails views and Vue components
• Lets you use ES6, TypeScript, CoffeeScript
• Supports Webpacker

Get started

Webpacker provides modern JS tooling for Rails. So we need to create a Rails project which which supports Vue first.

1. Create a new Rails app

$ rails new my-project --webpack=vue
$ cd my-project

2. Yarn add flexivue

$ yarn add flexivue

3. Use Flexivue webpack-helpers to automatically load instances files from a folder in your app

// app/javascript/packs/application.js
import Vue from "vue/dist/vue.esm"
import { Application } from "flexivue"
import { definitionsFromContext } from "flexivue/webpack-helpers"

const application = Application.initialize({ vue: Vue })
const context = require.context("instances", true, /\.js$/)

// Or addEventListener("turbolinks:load") if you use turbolinks
document.addEventListener("DOMContentLoaded", () => {
  application.load(definitionsFromContext(context))
})

4. Create a Vue instance

// app/javascript/instances/hello.js
import { Instance } from "flexivue"

export default class extends Instance {
  data = {
    name: "Flexivue"
  }
}

5. Link the JavaScript pack in Rails view using javascript_pack_tag helper

<!-- app/views/layout/application.html.erb in Head tag -->
<%= javascript_pack_tag 'application' %>

6. Render instance in a Rails view

<div instance="hello">
  <h1> Hello {{name}}</h1>
</div>

7. You can also use Vue components

<!-- app/javascript/components/counter.vue -->
<template>
  <div class="counter">
    <span>{{count}}</span>
    <button @click="inc">+</button>
  </div>
</template>

<script>
  export default {
    data() {
      return { count: 0 }
    },
    methods: {
      inc() { this.count++ }
    }
  }
</script>

8. Then update hello instance

import { Instance } from "flexivue"
import Counter from "../components/counter.vue"

export default class extends Instance {
  data = {
    name: "Flexivue"
  }

  components = {
    "counter": Counter
  }
}

9. Render instance with component in a Rails view

<div instance="hello" data={ greet: "Welcome!" }>
  <h1> Hello {{name}} </h1>
  <h1> {{greet}} </h1>
  <counter></counter>
</div>

Instance file naming

Typescript support

Flexivue supports Typescript, just fell free to use it.
