Stimulus Popover

A Stimulus controller to deal with HTML popover.


$ yarn add stimulus-popover

And use it in your JS file:

// Probably in app/javascript/controllers/index.js

import { Application } from '@hotwired/stimulus'
import Popover from 'stimulus-popover'

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

With remote content

In your controller:

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

In your routes:

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

In your view:

With server rendered content on the fly:

<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>

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

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

With local template

<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>


data-popover-url-valueundefinedURL to fetch the content.βœ…

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

πŸŽ› Extending Controller

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

import Popover from 'stimulus-popover'

export default class extends Popover {
  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.
