Zero to Rails & Vue

This is the Day 1 for a 5 day JavaScript & Rails workshop.

Instructions

• Clone this repo & run bundle install
• Install vue devtools if you haven't already.
• start the rails server
• open localhost:3000
• Use the videos & wireframe to complete the goals
• Complete the bonus goals if you wish

Goals

Presentation

• Follow the videos to create a vue-alert component
• Use what you've learned to create a vue-show-more component

Video 1: Include Vue.js in a Rails App

Video 2: Extract a Component

Video 3: Bring that Component to Life

Bonus Goals

• Research how to add animations and transitions to Vue's v-if
• Add a subtle fade out effect when the alert is dismissed
• Add a slide up and slide down effect when the show-more component is toggled.

Rails & Vue Cheatsheet

See also the product-detail-prototype branch for specific examples.

file boilerplate

// All javascript files start with this
;(function () {
  "use strict"

})();

Add vue to the project

vendor
└── assets
    ├── javascripts
    │   └── vue.js

In application.js

//= require vue

Boot the main Vue app

// app/assets/javascripts/main.js
;(function () {
  "use strict"

  $(document).ready(function () {

    new Vue({

      el: "body",

      data: {}

    })
  })
})();

Add a Vue component

<!-- app/views/vue_templates/_alert.html -->
<script id="alert-template" type="text/template">
  <div class="alert" v-if="isDisplayed">
    <button class="alert__close" aria-label="Close" v-on:click="dismiss">
      <span aria-hidden="true">×</span>
    </button>

  </div>
</script>

<%# in app/views/pages/home.html.erb %>

<vue-alert></vue-alert>

<%= render partial: "vue_templates/alert" %>

//app/assets/javascripts/components/alert.js
;(function () {
  "use strict"

  Vue.component("vue-alert", {

    template: "#alert-template",

    data: function () {
      return {
        isDisplayed: true
      }
    },

    methods: {
      dismiss: function () {
        var self = this
        self.isDisplayed = false
      }
    }

  })

}());
