Hello World
Make sure you know how to use
matestack-ui-core
before learning matestack-ui-vuejs
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

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

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

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) /

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;
}
}
}
