I am using rails-babel-transpiler gem mentioned in the official Babel site
Language API - ruby, for converting es6 code to es5.
The way I am transpiling, below is the erb file
<%
require 'babel/transpiler'
transfromed = Babel::Transpiler.transform("import HelloWrapper from '../assets/javascripts/components/HelloWrapper'; ReactDOM.render(<HelloWrapper />, document.getElementById('app'));")
%>
<%= javascript_tag do %>
<%= transfromed["code"].html_safe %>
<% end %>
It is getting rendered as
//<![CDATA[
'use strict';
function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { 'default': obj }; }
var _assetsJavascriptsComponentsHelloWrapper = require('../assets/javascripts/components/HelloWrapper');
var _assetsJavascriptsComponentsHelloWrapper2 = _interopRequireDefault(_assetsJavascriptsComponentsHelloWrapper);
ReactDOM.render(React.createElement(_assetsJavascriptsComponentsHelloWrapper2['default'], null), document.getElementById('app'));
//]]>
Can the above code be rendered in UMD way? I have used the plugin "transform-es2015-modules-umd" in babelrc file but it is not getting converted as a UMD module. Help me in figuring this out! Thanks

I need help with following code:
Rails 7.0.3
view.html.erb
<div id="calendar"></div>
importmap.rb
pin "fullcalendar", to: "https://ga.jspm.io/npm:fullcalendar#5.11.0/main.js"
javascript/application.js
import "fullcalendar"
javascript/controllers/fullcalendar_controller.js
import { Controller } from "#hotwired/stimulus"
import FullCalendar from 'fullcalendar'
export default class extends Controller {
connect() {
var calendarEl = document.getElementById('calendar');
var calendar = new FullCalendar.Calendar(calendarEl, {
initialView: 'dayGridMonth'
});
calendar.render();
}
}
layouts/applications.html.erb
<%= stylesheet_link_tag "application", "data-turbo-track": "reload" %>
<%= javascript_importmap_tags %>
And the output... :(
Failed to register controller: fullcalendar (controllers/fullcalendar_controller)
ReferenceError: exports is not defined
at main.js? [sm]:20877:37*
Any help would be appreciated
The issue is with calendar js file, you can download the fullcalendar js file to your local project, ./bin/importmap pin fullcalendar --download and then you can see fullcalendar.js file under vendors directory vendors/javascript/fullcalendar.js then replace that js file content with the full_calendar source https://cdn.jsdelivr.net/npm/fullcalendar-scheduler#5.11.2/main.js finally add export line to end of the fullcalendar.js file export default FullCalendar;. Hope it may help you with your issue.
importmap.rb includes
pin "javascript-autocomplete", to: "https://ga.jspm.io/npm:javascript-autocomplete#1.0.5/auto-complete.js"
And, following the rails guides, application.js was amended with
import "javascript-autocomplete"
although uncertainty about the syntax remains. Also attempted, as the script defines var autoComplete was
import autoComplete from "javascript-autocomplete"
in either instance, while the header shows:
<script type="importmap" data-turbo-track="reload">{
"imports": {
"application": "/assets/application-333b944449a4c540424142c36f01f97feebd58f2f41d10565ecfde32cb315110.js",

}
the body has
<%= javascript_tag do %>
var demo1 = new autoComplete({
[...]
});
<% end %>
which fails to run: Uncaught ReferenceError: autoComplete is not defined
so the script is not being accessed.
So where is this lacking?
I'm following along with the Angular/Rails tutorial at Thinkster and I've run into an issue which seems to be most likely be Angular-related. Everything works just fine until I get to the Angular Routing section. Simply put, the inline templates within the <script> tags do not load in the <ui-view></ui-view> element. I originally thought this may be due to having opened the page locally as a file rather than having it loaded from a server, but the same problem persists even after integrating Rails (using an older version of Sprockets, as pointed out in this similar but unrelated issue).
When I load the index page in either the browser as a file or as a URL when running the Rails server, I've inspected the HTML and, sure enough, the only thing it shows in the code are the divs and an empty <ui-view> element, indicating something just isn't adding up correctly. I've tried various things, including:
Using the newest version of ui-router (0.2.15 at this writing) rather than the version in the tutorial
Using <div ui-view></div> instead of <ui-view></ui-view>
Changing the value of 'url' in the home state to 'index.html', including using the full path to the file (file:///...)
Putting the contents of the inline <script> templates into their own files (without the <script> tags, of course) and specifying the 'templateUrl' field using both relative and full paths
Trying both Chrome and Firefox just to be extra certain
None of these things have worked, even when accessing http://localhost:3000/#/home when the Rails server is running after having integrated Angular into the asset pipeline in the Integrating the Front-end with the Asset Pipeline section of the tutorial. Indeed, the route loads but does not show anything more than a completely blank page with a lonesome and empty <ui-view> element when inspecting the HTML using Chrome's dev tools.
Given that the issue seems to occur even before the Rails portion, it does seem like something to do with Angular itself, but I've got no clue what's going on, especially since I've followed along to the letter.
I'm using Bower to manage the Angular dependencies and the HTML does show that the Angular javascript files in both the app/assets/javascripts directory and in the vendor/assets/bower_components directory are being loaded properly in the <head> section, so everything seems to be okay on the asset pipeline integration.
Versios I'm using:
Rails: 4.2.3
Ruby: 2.2.1p85
Angular: 1.4.3
ui-router: 0.2.15
The code I've got for the major moving parts is below:

'posts': []
};
o.getAll = function() {
return $http.get('/posts.json').success(function(data) {
angular.copy(data, o.posts);
});
};
return o;
}]);
If any other code is required to help uncover the problem, please let me know and I'll supply anything requested.
it seems that the angular-ui-router is incompatible with the new Rails sprockets. To fix this, add this earlier version of sprockets to your gemfile:
gem 'sprockets', '2.12.3'
And then run bundle update sprockets.
This was answered a few times in other similar questions, like the one below:
Angular Rails Templates just not working
$urlRouteProvider in my code should've been $urlRouterProvider. Be sure to double-check everything, folks, and make good use of the console!
I'm porting my symfony app to Ruby on Rails 4.2.0. My setup works fine in symfony. There is this old post on how to use dojo with RoR, but it uses deprecated code.
In my application.html.erb I have
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
I replaced the symfony wrappers with Rails ones. I also changed the dojo version. I was using 1.9.1. Rails generates this html:
<script>
dojoConfig = {async: true}
</script>
<script src="http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js">
The last line is followed by a bunch of compressed javascript and the close script tag in Firebug.
I didn't make any changes in my home/index.html.erb where I'm testing this code. In app/assets/javaascipts/home.js, I have:
//require(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip)
define(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip)
{
ready(function()
{
var head = "<div class='footnote-text'>";
var tail = "</div>";
var fnt1 = head + dom.byId("fnb1").innerHTML + tail;
var fnt2 = head + dom.byId("fnb2").innerHTML + tail;
var fnt4 = head + dom.byId("fnb4").innerHTML + tail;
new Tooltip({ connectId: ["footnote1"],position:["after","above","below"],label: fnt1 });
new Tooltip({ connectId: ["footnote2"],position:["after","above","below"],label: fnt2 });
new Tooltip({ connectId: ["footnote4"],position:["after","above","below"],label: fnt4 });
new Tooltip({ connectId: ["footnote5"],position:["after","above","below"],label: fnt4 });
});
});
//require(["dojo/dom", "dojo/ready", "dijit/Dialog"], function(dom, ready, Dialog){
define(["dojo/dom", "dojo/ready", "dijit/Dialog"], function(dom, ready, Dialog){
ready(function(){
var fnt3 = dom.byId("fnb3").innerHTML;
myDialog = new Dialog({
title: "Contact Me",
content: fnt3,
style: "width: 300px"
});
});
});
The commented out require lines are what I use in my symfony app. As you can see, I replaced them with define as described on the dojo site. When I run it, I get the following error on the Firebug console:
ReferenceError: define is not defined
...define(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip
If I used require instead of define, I get require is not defined.
Update
I tried installing dojo into the app and made some progress. I copied the download from dojo to vendor/assets/javascript/dojo. The dojo directory contains the subdirectories dojo, dojox, and digit
I then added
//= require dojo/dojo/dojo.js
to app/assets/javascript/application.js. I also changed the define back to require in the home.js file. When I reloaded the page, I got an error complaining that it couldn't find Tooltip. I then added:
//= require dojo/dijit/Tooltip.js
On reload it complained about a bunch of other missing js files. This is the same problem I had using symfony, which is why I went to the google image. How can I get to rails to search for the files in the vendor directories? This is one of the errors:
"NetworkError: 404 Not Found - http://amcolan.loc/dijit/_base/manager.js"
Update 2
Since require_tree worked for app assets, I thought it might work to vendor as well. I added
//= require_tree ../../../vendor/assets/javascripts/dojo
to my application.js file. When I reloaded the page, it took about a minute. My guess is that it's loading everything in the dojo directory tree, which is not surprising. The page load completed without any errors. When I hovered over a tooltip item (the purpose of the code is to show tooltips), Firebug cranked out about two thousand errors and quit. All the errors appear to be "ReferenceError: define is not defined"
Update 3
I went back to using the googleapi. My application.html.erb header looks like this
<head>
<meta charset="UTF-8">
<title><%= content_for?(:title) ? yield(:title) : "American Colonial Ancestors" %></title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
I reversed the order of the javascript includes. The page reloaded without errors. The tooltip doesn't work, but it doesn't generate any errors when I hover over an item. I put a bad statement in the home.js code and it came up on the console so I know the code is being parsed. I may just have a bug in my page setup.
There may be more than one way to get Dojo toolkit to work with Ruby on Rails. This is the easiest if not the most efficient way. This works in Rails 4.2.0. I would imagine it would work in other versions as well.
In views/layouts/application.html.erb add the following prior to the inclusion of the site scripts:
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
Change the version to the latest or to which ever one you want to use. Here I'm using version 1.10.3. The dojo site says there are other CDN's (Content Delivery Network) for the source code. I'm using google as it was in their example. Here are the pertinent parts of my head section:
<head>
<meta charset="UTF-8">
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag "http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dijit/themes/claro/claro.css" %>
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= content_for :page_script %>
<%= csrf_meta_tags %>
</head>
If you are going to use any of the toolkit's dialog boxes, tooltips, etc, you will need to include a stytlesheet by adding something like this:
<%= stylesheet_link_tag "http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dijit/themes/claro/claro.css" %>
Change the version and the theme to your own requirements. Here I'm using the claro theme. You can see it in my head section above. I don't think placement is critical. You also need to declare your theme class in the body statement. Here's mine:
<body class="claro">
An older post on the subject had different javascript formatting. I don't think anything special is needed. Here's an example of a working script:
require(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip)
{
ready(function()
{
var head = "<div class='footnote-text'>";
var tail = "</div>";
var fnt1 = head + dom.byId("fnb1").innerHTML + tail;
var fnt2 = head + dom.byId("fnb2").innerHTML + tail;
new Tooltip({connectId: ["footnote1"], position:["after","above","below"], label: fnt1 });
new Tooltip({connectId: ["footnote2"], position:["after","above","below"], label: fnt2 });
});
});
As mentioned in my question, I tried placing the Dojo Toolkit source in vendor/assets/javascript. Starting with with version 1.7, dojo started using Asynchronous Module Definition (AMD). It may be the case that the AMD loader is incompatible with the Rails pre-compile feature. I don't know enough about it to say for sure.
Environment: Rails 3.2.3, ruby 1.9.3-p125
My gemfile has the following in it:
gem 'calendar_date_select'
my layouts/application.html.erb has the following statement (as the last statement in the head section):
<%= calendar_date_select_includes %>
I installed the gem via gem install calendar_date_select
and ran rake bundle:install
I read the documentation, and some of the responses on StackOverflow, and here's what I ended up putting in my view:
<%= form_for(#panel) do |f| %>
.......
Start Date/Time: <%= f.calendar_date_select :start_time, :iso_date => true %>
I am getting the following error message:
undefined method `calendar_date_select' for #<#:0x007fae3b136938>
Any ideas?
I've switched from using that gem to just using jqueryUI which has the same functionality.
To do that:
view
= f.text_field :content_date, id: 'datepicker', size:10
= f.time_select :content_date, :ignore_date => true # Added later. not shown in screenshot
Gemfile
# Nothing - jquery & jqueryUI are now the default.
# Check web pages to see what really gets included (in the header).
application.js
%script
# The main code
$(function() {
$( "#datepicker" ).datepicker();
});
# This makes the pop-up show the actual db date by fixing a format difference.
$(function (){
var dateInput = $("#datepicker");
var format = 'yy-mm-dd';
dateInput.datepicker({dateFormat: format});
dateInput.datepicker('setDate', $.datepicker.parseDate(format, dateInput.val()));
});
Use this code to enable time in calender select tag
<%= f.calendar_date_select "date", :time => true , :readonly=>true, :popup=>"force" %>
