I have an import issue I can't understand, but I think I'm missing something big with either webpack or Symfony and I can't find what.
I hope you can tell me.
I try to use the reveal.js module. So, using npm I added the content of this github to my node_modules: https://github.com/hakimel/reveal.js/
Without looking at Symfony, only the index.html from the reveal.js module. There is an import line <script src="js/reveal.js"></script>
If this import is missing, then an error occured: Uncaught ReferenceError: Reveal is not defined
But with this import, all works fine.
If I'm telling you about this simple index.html, it's because I have the same error in my Symfony project, and I can't tell why because I think my imports are fine.
So either, my import is not ok...either the error is not the same, but I can't tell where she is.
In my webpack.config.js, I have this
.addEntry('js/app', [
'./assets/js/app.js',
'./node_modules/jquery/dist/jquery.slim.js',
'./node_modules/popper.js/dist/popper.min.js',
'./node_modules/bootstrap/dist/js/bootstrap.min.js',
'./node_modules/holderjs/holder.min.js',
'./node_modules/reveal.js/lib/js/head.min.js',
'./node_modules/reveal.js/js/reveal.js'
])
As you can see, the reveal.js file is there, so he is concatenate into my main js file. But still, I have this Uncaught ReferenceError: Reveal is not defined when I try to use <script>Reveal.initialize();</script> inside of a twig template.
I'm really lost for this moment, so I hope you can help one way or an other, thanks :(
EDIT: In order to add some information, in my build/app.js I can see the import is there.
/***/ "./node_modules/reveal.js/js/reveal.js":

I have this line in one of my tsx file:
import styles from "../../styles/buyTicket.module.css";
got this error:
ERROR in /Applications/MAMP/htdocs/wp-content/plugins/tikex/tikexModule/components/BuyTicket/PricingOptionInvoiceItemsFormFieldsCheckboxes.tsx
./tikexModule/components/BuyTicket/PricingOptionInvoiceItemsFormFieldsCheckboxes.tsx 7:19-54
[tsl] ERROR in /Applications/MAMP/htdocs/wp-content/plugins/tikex/tikexModule/components/BuyTicket/PricingOptionInvoiceItemsFormFieldsCheckboxes.tsx(7,20)
TS2307: Cannot find module '../../styles/buyTicket.module.css' or its corresponding type declarations.
If I remove styles then I got this error no more, but then it will work not as a CSS module, and naming collosion will happen. What would you suggest?
As far as i can understand, you may have a look here:
Can't import CSS/SCSS modules. TypeScript says "Cannot Find Module"
and here:
React, Typescript - Cannot find module ... or its corresponding type declarations
I would like to use CSS Houdini in a Next.js project I am building. I have installed, via yarn, both the CSS Houdini package I want to use along with css-paint-polyfill. I am following the webpack instructions here https://houdini.how/usage
Here is my component:
import 'css-paint-polyfill';
import workletURL from 'url-loader!css-houdini-lines';
import styles from './Separator.module.css';
CSS.paintWorklet.addModule(workletURL);
export default function Separator() {
return <div className={styles.separator} />;
}
I am getting the dreaded
error - ReferenceError: window is not defined
at /home/tithos/code/web/new-tim/node_modules/css-paint-polyfill/dist/css-paint-polyfill.js:1:239
I tried putting the import for css-paint-polyfill in a useEffect, but the throw another error. I even tried const DynamicComponent = dynamic(() => import('../components/hello')) from https://nextjs.org/docs/advanced-features/dynamic-import, but I did not know how to reference the library.
Has any one solved this?
Seems like CSS Paint Polyfill eagerly accesses window, which means it will throw an error when in an environment which has no window, such as server phase of Next. There are multiple things you can do.
Modify your next.config.js to stub the aforementioned module when for Webpack when isServer is true. You can follow this page of the Next docs for this.
Create a dynamic component that's only imported on the client (I see you've tried this, but it should have worked, so maybe if you shared what you did in this regard, I could work out what's wrong with your approach).
Create an issue and send in a PR to the repository where the Polyfill is hosted to lazily access window depending on whether it's available or not.
I am using Meteor with React and Semantic-ui-react. I needed a toast function so I wanted to change to Fomantic UI. Everything related is loaded by NPM.
I removed semantic-ui-css and added fomantic-ui-css.
I removed the
<link rel="stylesheet" href="//cdn.jsdelivr.net/npm/semantic-ui#2.4.2/dist/semantic.min.css" /> from the head.
I changed all import 'semantic-ui-css/semantic.min.css'; to import 'fomantic-ui-css/semantic.css';
When I try to execute a
$('body')
.toast({
title: 'LOOK',
message: 'See, how long i will last',
showProgress: 'bottom'
})
;
I get TypeError: $(...).toast is not a function
I can't find anything on it over various searches through SO and repository issues.
Thanks for any help you can give!!

You basically need to import the semantic.js file, which will add the functionality to your jquery instances:
import 'fomantic-ui-css/semantic.js'
import 'fomantic-ui-css/semantic.css'
However, there is no need to import the .min.* minified files, because Meteor will use a js and css minifier when you build your app for production / deployment later.
Using Symfony 4 and Webpack Encore, I can't get Select2 to work.
I'm using select2#4.0.3 and importing it this way in app.js:
import $ from 'jquery';
import 'bootstrap';
import 'select2';
I also tried to use
Encore.autoProvidejQuery()
in webpack.config.js, then taking care of commenting the
import $ from 'jquery';
line in app.js so that jquery is not imported twice.
I tried everything I could find in other answsers like:
import select2 form 'select2';
$(() => {
$('.select2-enable').select2();
});
or
select2($);
Almost all my attempts result in the same error:
TypeError: $(...).select2 is not a function
EDIT:
Working now. Everytime I made a change in app.js (and rebuilt) I used the firefox devtool console to check if it was working but I always got the
not a function
error even though the problem was solved and select2 was working.
Is this because I'm using Webpack that the browser console doesn't recognize the select2() function anymore?
First install it using yarn:
yarn add select2
Then use it with require instead of import:
require('select2')
at your app.js file.
It works the same using require or import.
Babel converts import and export declaration to CommonJS (require) which lets you load modules dynamically.
So, despite of them looking the same, try to always use require.
The general error: SyntaxError: Invalid or unexpected token, referencing line 1 of index.css.
This is the result of encountering CSS syntax in a CSS file that I'm trying to import for styling.
Attempted fixes and experiments:
Deleted everything out of the CSS file and exported an empty JS module. This works, verifying that the import is treating it as a JS file, not CSS.
Removing the #import statement from line 1 of the CSS file. Of course, this fails to make a difference because the remaining CSS syntax throws the same error.
Paired down the Webpack config file to eliminate the surface area of the problem. Rendering should be handled by Webpack, so the issue may reside there. Config was very basic and set to handle CSS, SASS, JS, and JSX.
Tried importing the CSS file from other file locations, including the server's app.js file.
Tried making use of ExtractTextPlugin as an bundling alternative.
Tried making use of Isomorphic Style Loader.
All in all, given the attempted fixes and tests listed above, the issue seems unrelated to Webpack per se. It's as if the server side rendering is attempting to import the CSS file before Weback gets involved.
The fix, it turns out, was to use the ignore-styles package in our server app.js file:
require('ignore-styles')
The description as listed on the repo:
A babel/register style hook to ignore style imports when running in Node. This is for projects that use something like Webpack to enable CSS imports in JavaScript.
