I will try to be concise, I must work on a Reactjs project for school project, my task is to take a existing html/css theme and and put it in React components.
But I have a problem since the start, I used CreateReactApp for a clean start and import index.css of the theme.
Create a basic form base on the theme and have this error. (She disapear when I delete index.css)
Error I see
Failed to compile
./src/css/index.css
Module not found: Can't resolve '../images/category-1-bg.jpg' in
'C:\Users\50031\Documents\React-Project-master\src\css'
Structure of the project is that
Structure project
Thanks so much, I already check for an answer but I suck as hell in code and understand nothing.... Sorry
Your images directory is not inside css directory and that is what the error says. This is because somewhere in your index.css you have not assigned correct path for the images. Assign correct paths to the images in your index.css and the app should compile.
Install css-loader so that it will include the image during build time.

I am working through the Odin Project and am stuck on the first lesson where we must build a webapp using webpack. I followed the tutorials here and hereon webpack's website, and I was able to get them to work. However, when I try to set up my own files to build my own project, I can't get CSS to load or a function in my index.js file.
I have the same directory style set up, and have even tried using the exact same index.js file they use in the tutorial.
I expect to get: a webpage to load that says "hello webpack" in red text.
Instead, I get this error: when I run $npx webpack, it says:
ERROR in ./src/style.css 1:0
Module parse failed: Unexpected token (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
> .hello{
| color: red;
| }
# ./src/index.js 1:0-21
Upon googling the error, I found a stack overflow article and I tried renaming my rules array to 'loaders' in my .config file as this article suggests, but I still get the same error.
“You may need an appropriate loader to handle this file type” with Webpack and CSS
Also weird is the fact that some of the code in my index.js file works, and some does not. To elaborate, my console.log and alert works just fine after I run $npx webpack and load the page. However, they function that is supposed to add "hello webpack" to the DOM, does not, as evidence by the fact that nothing shows up at all. The page itself is blank.
My index.js code:
import './style.css';
console.log("console works");
alert("alert works");
function component() {
const element = document.createElement('div');
// Lodash, now imported by this script
element.innerHTML = _.join(['Hello', 'webpack'], ' ');
element.classList.add('hello');
return element;
}
document.body.appendChild(component());
You will notice that it is nearly the exact same as the asset management index.js file from the webpack tutorial. I did this purposely to have as little variance as possible between my stuff and the tutorial.
I don't know if it is too much information, but a link to the whole repo as it currently is set up can be found here
Update:
I re-setup the file from the ground up and noticed that the CSS stopped working when I went out of my way to change the bundle.js link they had in their example to main.js. While I double-checked to make sure that I made the correct corresponding changes to output in my config file, making this change had the sum total outcome of not allowing my CSS to work for some reason.
What this reason is? I have no idea, and would be very interested to learn why this happened if someone has a suggestion
But on the offchance that one of my fellow Odin learners googles this problem, I kept the example's bundle.js instead of changing to main.js as my output script and it worked fine.
I'm going to update my github now so my original github link will likely be out of date going forward.
Going through your GitHub repo commit history, I see that at some point you named your Webpack configuration file weback.config.js instead of webpack.config.js (the p was missing). This was likely the source of the problem, as Webpack couldn't find a loader configuration for the .css file you're importing.
Firstly, I am loving vite!
However, I am having a problem when importing my CSS file from a JS file.
The CSS file looks like this;
#tailwindcss base;
#tailwindcss components;
#tailwindcss utilities;
The error;
[vite]: Rollup failed to resolve import "about-page-globals.css" from "src/ux-about.js". This is most likely unintended because it can break your application at runtime. If you do want to externalize this module explicitly add it to 'build.rollupOptions.external'
I'm Vite in a shopify theme development project. What I want to achieve are two files, a JS and a CSS that get bundled and outputted to /dist directory.
I'm looking to use Vite across all future projects so I really want to get a good grasp of how to set it up.
Any pointers are much appreciated 🙏🏽
I'm creating a utility project that will supply React components and resources to my other projects.
I'd like it to include a set of images (mostly .png files for icons) that can then be imported by the child projects.
I can't figure out how to make this work.
I can export the images from the library, and I can see them, name-mangled, in the node_modules of the child project. So, all good so far.
But, import {imgName} from "myLib" does not include the file in the child project's bundle.
It looks to me like my problem is explained by a clue in https://create-react-app.dev/docs/adding-images-fonts-and-files/:
You can import a file right in a JavaScript module. This tells
webpack to include that file in the bundle.
Presumably, CRA is not triggering this webpack behavior in my case, since I'm importing from another module, not from a file.
How can I get things working?
Assume:
I have complete ownership of the library and child projects, so I can change this solution in whatever way works. I just want to have a single common resource for the images.
I don't want to eject my child projects
Ideally, any complexity should be in the library project. The child projects should have minimal complex tooling. (My intent is for this library to be used by a team of other developers, who will want to focus on their own tasks; not on tooling details)
EDIT (ADDED LATER)
Per the comments in the first answer below, I've created a simple example of my problem. See:
Library repo: github.com/deg/media-file-bug-library
Library package: npmjs.com/package/media-file-bug-library
Client repo: github.com/deg/media-file-bug-client
Just pull the client repo and do yarn install and yarn start. This will bring up a little web page that shows the problem:
SCREEN SNAPSHOT:
The Problem is Not in CRA Trigger. Importing Png File like JavaScript Hides a Magic. Here you are importing a Image and Exporting it which then get Processed by bundler and The Bundled Index Actually Exports The name of the Processed Image File Which in Your Case is corss~nAalnlvj.png. That's Why Your Image is Broken but you are able to render name of File, The Case is Same for microbundle or parcel.
How You Can solve it is by separating your assets and components By Placing Images on separate assets folder and place your images there and then add assets to files in your files in package.json
{
.
.
"files": [ "dist", "assets"],
}
And Then Import Image & Using Like This
import React from 'react'
import ico_cross from 'media-file-bug-library-fix/assets/cross.png'
function App() {
return (
<div className="App">
<img src={ico_cross} alt="im"/>
</div>
);
}

hey David I found the solution please do check the above screenshot
as in you package just change in index.modern.js
// WebPack doesnt listen as a path it listen
// var cross = "cross~nAalnlvj.png";
// use import rather than simple name as it generate a full absolute path at parent level so that in child level it can be accessible as an Image
import cross from "./cross~nAalnlvj.png"
I decided to try out WebPack on a new project I'm spinning up today and I'm getting really strange behavior from the sourcemaps. I can't find anything about it in the documentation, nor can I find anyone else having this issue when skimming StackOverflow.
I'm currently looking at the HelloWorld app produced by Vue-CLI's WebPack template -- no changes have been made to the code, the build environment, or anything.
I installed everything and ran it like so:
vue init webpack test && cd test && npm install && npm run dev
Looking at my sourcemaps, I see the following:
This is a hot mess. Why are there three version of HelloWorld.vue and App.vue? Worse yet, each version has a slightly different version of the code and none of them match the original source. The HellowWorld.vue sitting in the root directory does match the original source, but what's it doing down there instead of in the ./src/components folder? Finally, why isn't there a fourth App.vue that has the original source for it?
As far as I can tell this may have something to do with the WebPack loaders. I've never gotten these kinds of issues with any other bundler, though. Below is an example of the exact same steps using the Browserify Vue-CLI template:
No webpack:// schema, only one copy of every file, the files actually contain the original source code (kind of important for source maps), no unexpected (webpack)/buildin or (webpack)-hot-middleware, no . subdirectory,.... just the source code.
I haven't worked with Vue so can't really describe how exactly this is happening but it seems to be related to Vue Loader. Looking at the documentation I did not really find anything that clarifies why it would create three different files for one component. But it does seem logical considering that a .vue file might contain three types of top-level language blocks: <template>, <script>, and <style>.
Also, looking at two of those files you do see a comment at end of each file that suggests it was modified in some way by a Vue loader. Either this
//////////////////
// WEBPACK FOOTER
// ./node_modules/vue-loader/lib/template-compiler
or
//////////////////
// WEBPACK FOOTER
// ./node_modules/vue-style-loader!./node_modules/css-loader
The third file is different but it still does have code that identifies it as being modified by Vue loader. Here is some of that code
function injectStyle (ssrContext) {
if (disposed) return
require("!!vue-style-loader...")
}
/* script */
import __vue_script__ from "!!babel-loader!../../node_modules/vue-loader/..."
/* template */
import __vue_template__ from "!!../../node_modules/vue-loader/..."
/* styles */
var __vue_styles__ = injectStyle
The document also says this:
vue-loader is a loader for Webpack that can transform Vue components written in the following format into a plain JavaScript module:
Which explains why you might not see the same type of behaviour with other bundlers.
Now, This might not be the answer you were looking for but just wanted to share what I had found.
This is actually a feature of webpack.
webpack has HMR (Hot Module Reloading). If you look in your network tab, go ahead and make an update to your HelloWorld.vue file. You'll see a js chunk come thru as well as an updated JSON manifest. Both of these will have a unique hash at the end for each time you make a change to the application. It does this so the browser does not have to do a full reload.
For a better explanation of this I would highly recommend reading through https://webpack.js.org/concepts/hot-module-replacement/
The question is simple although the approach can vary.
First I am using the following:
1 - Webpack
2 - Babel
3 - ES6
4 - npm
I have the module Bootstrap included but can't figure out how to call the JS file via import
This is how I'm approaching it:
import Bootstrap from 'bootstrap'; and that doesn't work so my first problem is not being able to access bootstrap so i can't even begin to figure out how to access the bootstrap.js file.
The second approach was to scrap the idea of accessing Bootstrap from the node-modules folder and just add bootstrap.css and bootstrap.js to the src directory in my React build.
What I then tried was to access bootstrap css like this:
import './css/bootstrap.css'; and that works fine.
But when i attempt to import, bootstrap.js like this import './js/bootstrap.js I get an error when React tries to compile.
The image above shows how I'm trying to import my local JS file.
Any ideas what I'm doing wrong.
I would love either a solution using the bootstrap module (which is cleaner so I don't have to manually include) but would also like to know how to manually include as well.
Thank you.
You need to use the bootstrap WebPack package.
