Stimulus Remote Rails

A Stimulus controller to handle Rails UJS events.

Installation

$ yarn add stimulus-remote-rails

And use it in your JS file:

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

import { Application } from '@hotwired/stimulus'
import Remote from 'stimulus-remote-rails'

const application = Application.start()
application.register('remote', Remote)

Usage

In your controller:

class CommentsController < ApplicationController
  def create
    @comment = Comment.new(comment_params)

    if @comment.save
      render @comment
    else
      render partial: 'comments/form', locals: { comment: @comment }, status: :unprocessable_entity
    end
  end

  private

  def comment_params
    params
      .require(:comment)
      .permit(:content)
  end
end

In your view:

<%= form_with model: @comment, data: { controller: 'remote', action: 'ajax:success->remote#append ajax:error->remote#replace' } do |f| %>
  <% if f.object.errors.any? %>
    <% f.object.errors.full_messages.each do |error| %>
      <p><%= error %></p>
    <% end %>
  <% end %>

  <%= f.label :content %>
  <%= f.text_field :content %>

  <%= f.submit 'Save comment' %>
<% end %>

With a link_to:

<%= link_to 'Click me to append content', content_path, remote: true, data: { controller: 'remote', action: 'ajax:success->remote#append' } %>

<%= link_to 'Click me to prepend content', content_path, remote: true, data: { controller: 'remote', action: 'ajax:success->remote#prepend' } %>

<%= link_to 'Click me to replace content', content_path, remote: true, data: { controller: 'remote', action: 'ajax:success->remote#replace' } %>

You can use append, prepend or replace methods with the events of your choice.

Don't forget to add the remote: true attribute in your link_to!

You can use it with all remote elements available in Rails UJS.

🎛 Extending Controller

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

import Remote from 'stimulus-remote-rails'

export default class extends Remote {
  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.
