matestack-ui-vuejs

Boost your productivity & easily create reactive web UIs in pure Ruby.
matestack-ui-vuejs ships all you need to build reactive UIs in pure Ruby orchestrating prebuilt Vue.js components with a simple Ruby DSL. 
The prebuilt reactive components built on top of Vue.js are covering typical features of a reactive web UI, such as async form submission, dynamic page transitions or async partial UI updates. No Opal involved
If required, it can be easily extended with pure JavaScript.

Feature walk-through
1. Use reactive UI components in pure Ruby
Matestack's generic, reactive components can be placed on your UI with a simple Ruby DSL. While putting these generic components in your UI code, you inject some configuration in order to adjust the behaviour to your needs. This enables you to create reactive UIs without touching JavaScript!
Behind the scenes: When calling a reactive component with the Ruby DSL, Matestack will render a special component tag with a bunch of attributes to the resulting, server-side rendered HTML. Within the browser, Vue.js will pick up these component tags and mount the JavaScript driven components on it.
Toggle parts of the UI based on events
matestack-ui-vuejs offers an event hub. Reactive components can emit and receive events through this event hub. "onclick" and "toggle" calling two of these reactive core components. "onclick" emits an event which causes the body of the "toggle" component to be visible for 5 seconds in this example.
app/matestack/components/some_component.rb
class Components::SomeComponent < Matestack::Ui::Component
​
  def response
    onclick emit: "some_event" do
      button "click me"
    end
    toggle show_on: "some_event", hide_after: 5000 do
      plain "Oh yes! You clicked me!"
    end
  end
​
end
Call controller actions without JavaScript
Core components offer basic dynamic behaviour and let you easily call controller actions and react to server responses on the client side without full page reload. The "action" component is configured to emit an event after successfully performed an HTTP request against a Rails controller action, which is received by the "toggle" component, displaying the success message.
app/matestack/components/some_component.rb
class Components::SomeComponent < Matestack::Ui::Component
​
  def response
    action my_action_config do
      button "click me"
    end
    toggle show_on: "some_event", hide_after: 5000 do
      plain "Success!"
    end
  end
​
  def my_action_config
    {
      path: some_rails_route_path,
      method: :post,
      success: {
        emit: "some_event"
      }
    }
  end
​
end
Dynamically handle form input without JavaScript
Create dynamic forms for ActiveRecord Models (or plain objects) and display server side responses, like validation errors or success messages, without relying on a full page reload. Events emitted by the "form" component can be used to toggle parts of the UI.
app/matestack/components/some_component.rb
class Components::SomeComponent < Matestack::Ui::Component
​
  def response
    matestack_form my_form_config do
      form_input key: :some_model_attribute, type: :text
      button "click me", type: :submit
    end
    toggle show_on: "submitted", hide_after: 5000 do
      span class: "message success" do
        plain "created successfully"
      end
    end
    toggle show_on: "failed", hide_after: 5000 do
      span class: "message failure" do
        plain "data was not saved, please check form"
      end
    end
  end
​
  def my_form_config
    {
      for: MyActiveRecordModel.new,
      path: some_rails_route_path,
      method: :post,
      success: {
        emit: "submitted"
      },
      failure: {
        emit: "failed"
      }
    }
  end
​
end
Implement asynchronous, event-based UI rerendering in pure Ruby
Using Matestack's built-in event system, you can rerender parts of the UI on client side events, such as form or action submissions. Even server side events pushed via ActionCable may be received! The "async" component requests a new version of its body at the server via an HTTP GET request after receiving the configured event. After successful server response, the DOM of the "async" component gets updated. Everything else stays untouched.
app/matestack/components/some_component.rb
class Components::SomeComponent < Matestack::Ui::Component
​
  def response
    matestack_form my_form_config do
      #...
    end
    #...
    async rerender_on: "submitted", id: "my-model-list" do
      ul do
        MyActiveRecordModel.last(5).each do |model|
          li model.some_attribute
        end
      end
    end
  end
​
  def my_form_config
    {
      #...
      success: {
        emit: "submitted"
      },
      failure: {
        emit: "failed"
      }
    }
  end
​
end
Manipulate parts of the UI via ActionCable
"async" rerenders its whole body - but what about just appending the element to the list after successful form submission? The "cable" component can be configured to receive events and data pushed via ActionCable from the server side and just append/prepend new chunks of HTML (ideally rendered through a component) to the current "cable" component body. Updating and deleting is also supported!
app/matestack/components/some_component.rb
class Components::SomeComponent < Matestack::Ui::Component
​
  def response
    matestack_form my_form_config do
      #...
    end
    #...
    cable prepend_on: "new_element_created", id: "some-cable-driven-list" do
      MyActiveRecordModel.last(5).each do |model|
        Components::SomeListItemComponent.call(content: model.some_content)
      end
    end
  end
​
end
app/controllers/some_controller.rb
# within your controller action handling the form input
ActionCable.server.broadcast("matestack_ui_core", {
  event: "new_element_created",
  data: Components::SomeListItemComponent.call(content: model.some_content) # or plain HTML
})
Easily extend with Vue.js
Matestack's dynamic parts are built on Vue.js. If you want to implement custom dynamic behaviour, you can simply create your own Vue components and use them along Matestack's components. It's even possible to interact with Matestack's components using the built-in event bus.
app/matestack/components/some_component.rb
class Components::SomeComponent < Matestack::Ui::Component
​
  def response
    Components::MyVueJsComponent.call()
    toggle show_on: "some_event", hide_after: "3000" do
      span class: "message success" do
        plain "event triggered from custom vuejs component"
      end
    end
  end
​
end
app/matestack/components/my_vue_js_component.rb
class Components::MyVueJsComponent < Matestack::Ui::VueJsComponent
​
  vue_name "my-vue-js-component"
​
  def response
    div class: "my-vue-js-component" do
      button "@click": "vc.increaseValue"
      br
      plain "{{ vc.dynamicValue }}!"
    end
  end
​
end
app/matestack/components/my_vue_js_component.js
import MatestackUiVueJs from 'matestack-ui-vuejs'
​
const myComponent = {
  mixins: [MatestackUiVueJs.componentMixin],
  template: MatestackUiVueJs.componentHelpers.inlineTemplate,
  data: () => {
    return {
      dynamicValue: 0
    };
  },
  methods: {
    increaseValue(){
      this.dynamicValue++
      MatestackUiVueJs.eventHub.$emit("some_event")
    }
  }
}
​
export default myComponent
​
// and then in your application pack file you register the component like:
​
appInstance.component('my-vue-js-component', myComponent) /
3. Create whole SPA-like apps in pure Ruby
The last step in order to leverage the full Matestack power: Create a Matestack layout (~Rails layout) and Matestack page (Rails ~view) classes (as seen on matestack-ui-core) and implement dynamic page transitions with components coming from matestack-ui-vuejs without any custom JavaScript implementation required.
Create your layouts and views in pure Ruby
The layout class is used to define a layout, usually containing some kind of header, footer and navigation. The page class is used to define a view. Following the same principles as seen on components, you can use components (core or your own) in order to create the UI. The matestack_vue_js_app page_switch and transition components enable dynamic page transition, replacing the yielded content with new serverside rendered content rendered by the requested page.
app/matestack/some_app/some_layout.rb
class SomeApp::SomeLayout < Matestack::Ui::Layout
​
  def response
    h1 "My App"
    matestack_vue_js_app do
      nav do
        transition path: page1_path do
          button "Page 1"
        end
        transition path: page2_path do
          button "Page 2"
        end
      end
      main do
        div class: "container" do
          page_switch do
            yield
          end
        end
      end
    end
  end
​
end
app/matestack/some_app/pages/page1.rb
class SomeApp::Pages::Page1 < Matestack::Ui::Page
​
  def response
    div class: "row" do
      div class: "col" do
        plain "Page 1"
      end
    end
  end
​
end
app/matestack/some_app/pages/page2.rb
class SomeApp::Pages::Page2 < Matestack::Ui::Page
​
  def response
    div class: "row" do
      div class: "col" do
        plain "Page 2"
      end
    end
  end
​
end
Layouts and pages are referenced in your Rails controllers and actions
Instead of referencing Rails layouts and views on your controllers, you just use apps and pages as substitutes. Work with controllers, actions and routing as you're used to! Controller hooks (e.g. devise's authenticate_user) would still work!
app/controllers/some_controller.rb
class SomeController < ApplicationController
​
  include Matestack::Ui::Core::Helper
​
  matestack_layout SomeApp::SomeLayout
​
  def page1
    render SomeApp::Page1
  end
​
  def page2
    render SomeApp::Page2
  end
​
end
app/config/routes.rb
Rails.application.routes.draw do
​
  root to: 'some#page1'
​
  get :page1, to: 'some#page1'
  get :page2, to: 'some#page2'
​
end
Use CSS animations for fancy page transition animations
Use Matestack's css classes applied to the wrapping DOM structure of a page in order to add CSS animiations, whenever a page transition is performed. You can even inject a loading state element, enriching your page transition effect.
app/matestack/some_app/some_layout.rb
class SomeApp::SomeLayout < Matestack::Ui::Layout
​
  def response
    h1 "My App"
    matestack_vue_js_app do
      nav do
        transition path: page1_path do
          button "Page 1"
        end
        transition path: page2_path do
          button "Page 2"
        end
      end
      main do
        div class: "container" do
          page_switch do
            yield
          end
        end
      end
    end
  end
  
  def loading_state_element
    div class: 'some-loading-element-styles'
  end
​
end
app/assets/stylesheets/application.scss
.matestack-page-container{
​
  .matestack-page-wrapper {
    opacity: 1;
    transition: opacity 0.2s ease-in-out;
​
    &.loading {
      opacity: 0;
    }
  }
​
  .loading-state-element-wrapper{
    opacity: 0;
    transition: opacity 0.3s ease-in-out;
​
    &.loading {
      opacity: 1;
    }
  }
​
}
