Notification

GitHub

A Stimulus controller for showing notifications.

Installation

  1. Install the package

    Terminal
    $ yarn add @stimulus-components/notification

  2. Register the controller in your application

    app/javascript/controllers/index.js
    import { Application } from '@hotwired/stimulus'
import Notification from '@stimulus-components/notification'

const application = Application.start()
application.register('notification', Notification)

This controller uses stimulus-use/use-transition under the hood. You can change the animation behavior as you want.

Example

Notification

Reload to re-run the animation.

This alert will magically disappear!

Pretty cool, huh?

Usage

app/views/index.html
<div
  data-controller="notification"
  data-notification-delay-value="2000"
  class="transition transform duration-1000 hidden"
  data-transition-enter-from="opacity-0 translate-x-6"
  data-transition-enter-to="opacity-100 translate-x-0"
  data-transition-leave-from="opacity-100 translate-x-0"
  data-transition-leave-to="opacity-0 translate-x-6"
>
  <p>This alert will magically disappear!</p>

  <button data-action="notification#hide">Close</button>
</div>

You can hide the notification by default and open it programmatically. Use a CustomEvent and set the correct value and action.

For instance:

app/views/index.html
<div
  data-controller="notification"
  data-notification-hidden-value="true"
  data-action="awesome@window->notification#show"
  class="transition transform duration-1000 hidden"
  data-transition-enter-from="opacity-0 translate-x-6"
  data-transition-enter-to="opacity-100 translate-x-0"
  data-transition-leave-from="opacity-100 translate-x-0"
  data-transition-leave-to="opacity-0 translate-x-6"
>
  <p>This alert will magically disappear!</p>

  <button data-action="notification#hide">Close</button>
</div>

<script>
  document.addEventListener("DOMContentLoaded", () => {
    const event = new CustomEvent("awesome")

    window.dispatchEvent(event)
  })
</script>

Extending Controller

You can use inheritance to extend the functionality of any Stimulus component:

app/javascript/controllers/notification_controller.js
import Notification from "@stimulus-components/notification"

export default class extends Notification {
  connect() {
    super.connect()
    console.log("Do what you want here.")
  }
}

This controller will automatically have access to targets defined in the parent class.

If you override the connect, disconnect or any other methods from the parent, you'll want to call super.method() to make sure the parent functionality is executed.
