Stimulus Popover

GitHub Live preview

A Stimulus controller to deal with HTML popover.

Installation

Install the package
```
$ yarn add @stimulus-components/popover
```
Register the controller in your application
app/javascript/controllers/index.js
```
import { Application } from '@hotwired/stimulus'
import Popover from '@stimulus-components/popover'

const application = Application.start()
application.register('popover', Popover)
```

Usage

With remote content

In your controller:

app/controllers/users_controller.rb

class UsersController < ApplicationController
  def card
    render partial: 'users/card', locals: { user: @user }
  end
end

In your routes:

config/routes.rb

Rails.application.routes.draw do
  get :card, to: 'users#card'
end

With server rendered content on the fly:

app/views/index.html.erb

<div data-controller="popover" data-popover-url-value="<%= card_path %>">
  You can load popover with AJAX. For instance, this is my
  <a href="/profile" data-action="mouseenter->popover#show mouseleave->popover#hide">profile card</a>
</div>

In the card partial app/views/users/_card.html.erb:

app/views/users/\_card.html.erb

<div data-popover-target="card">
  <p>This content is loaded with AJAX.</p>
</div>

With local template

app/views/index.html

<div data-controller="popover">
  This is my GitHub card available on
  <a href="/profile" data-action="mouseenter->popover#show mouseleave->popover#hide"> GitHub </a>

  <template data-popover-target="content">
    <div data-popover-target="card">
      <p>This content is in a hidden template.</p>
    </div>
  </template>
</div>

Configuration

Attribute	Default	Description	Optional
`data-popover-url-value`	`undefined`	URL to fetch the content.	✅

Important note: It's up to you to provide the popover style!

Extending Controller

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

app/javascript/controllers/popover_controller.js

import Popover from '@stimulus-components/popover'

export default class extends Popover {
  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.
