Stimulus Rails Autosave

A Stimulus controller to autosubmit Rails forms.


$ yarn add stimulus-rails-autosave

And use it in your JS file:

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

import { Application } from '@hotwired/stimulus'
import Autosave from 'stimulus-rails-autosave'

const application = Application.start()
application.register('autosave', Autosave)

πŸ‘€ Demo

See demo β†’


<%= form_with model: @todo, data: { controller: 'autosave' } do |f| %>
  <div class="field">
    <%= f.label :description %>

    <!-- With custom event! -->
    <%= f.text_field :description, data: { action: 'keyup->autosave#save' } %>

  <div class="field">
    <%= f.label :completed %>
    <%= f.check_box :completed, data: { action: 'autosave#save' } %>

  <%= f.submit %>
<% end %>

πŸŽ› Extending Controller

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

import Autosave from 'stimulus-rails-autosave'

export default class extends Autosave {
  static values = {
    delay: {
      type: Number,
      default: 1000, // You can change the default delay here.

  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.
