I am new to webpack. I am trying to access my assets file outside of the src folder during development mode. The only solution I found in the internet is using copy-webpack-plugin. But I think that is for build. But since I am in development mode all things will load into memory. I might be wrong.
This is my file structure right now
File Sturcutre
And I am trying to access those file in index.html

NB: I am using react#17.0.2, webpack#4.43.0
Webpack just loads images that was in the webpack flow... If you want to copy extra assets you will need plugins like copy-webpack-plugin as you say.
loaders:
{
test: /\.(jpg|jpeg|png|woff|woff2|eot|ttf|svg)$/,
loader: 'url-loader?limit=100000'
}
Just would copy the *..(jpg|jpeg|png|woff|woff2|eot|ttf|svg) files that are imported in tree generated by the entry (entry: './src/index.js'). In your case the image was imported in the index.html file, which is not in the file tree generated by the webpack entry. If you import that image on './src/index.js' you will see the image in the output folder dist

I keep getting the same error. I have not touched Webpacker for the past 5 builds, and suddenly getting errors for a small change in some simple code. Really starting to baffle me.
I seem to be getting a space in the word 'loader', on the 'ERROR in Error line (4). I feel that is the cause.
Here is the output error:

Just got the same error, even though everything was locked down with package-lock.json files, and was building successfully 2 days ago.

the above line is not loading my index.css into browser while inside src/components level, i do have css files, whichare properly getting bundeled and delivered in bundle.css file.
Any help would be of great help
The link to the css should be:
<link rel="stylesheet" type="text/css" href="/index.css">
This should be like this due to the publicPath. Since it is not set, it is by default /.
The link to the css should be:
<link rel="stylesheet" type="text/css" href="../src/index.css">
I have created my webpack config file below:
const HtmlWebPackPlugin = require('html-webpack-plugin');
module.exports = {
entry: './src/main.js',
output: {
filename: 'bundle.js'
},
module: {
rules: [
{
test: /\.js$/,
exclude: '/node_modules/',
use: [
{
loader: 'babel-loader'
}
]
},
{
test: /\.html$/,
use: [
{
loader: 'html-loader',
options: {minimize: true}
}
]
}
]
},
plugins: [
new HtmlWebPackPlugin({
template: './src/index.html',
filename: './index.html'
})
]
};
and added all the necessary packages babel with env and react presets. I have my index.html file and TestComponent like below:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>React 16 Webpack Setup</title>
</head>
<body>
<script src="bundle.js" type="text/javascript"></script>
<div id="test">
</div>
</body>
</html>
and component code:
import React, { Component } from 'react';
export default class TestComponent extends Component {
render(){
return (
<div>
<h2>React Setup</h2>
</div>
)
}
}
Here's my main.js file where I'm hosting the component:
import React from "react";
import ReactDOM from "react-dom";
import Test from './TestComponent';
ReactDOM.render(<Test/>, document.getElementById("test"));
The problem is that when I run this script from package.json, I don't get any output/dist folder and also the component doesn't render in the browser. On which url do I have to visit to see the output just like with create-react-app?
Import your <script> at the bottom of the <body> tag in the HTML.
In your case, the browser is reading through the DOM and finding the <script> tag before it is finding the <div id="text"> node. What this means is that the browser will read through your script, and then try and render your <Test/> component into an HTML node with the id="test". The browser can't find the HTML node with the id="test" though because it hasn't read it yet, so it fails.
Make sense? See below...
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>React 16 Webpack Setup</title>
</head>
<body>
<div id="test"></div>
{* import scripts at the bottom of the body *}
<script src="bundle.js" type="text/javascript"></script>
</body>
</html>
Hope this helps, let me know if you're still running into issues.
I just finished learning ReactJS and was trying to go start learning webpack. I was curious if I could turn my existing website (server-side) structure into react type website (SPA). But my only issue is that I am using a lot of vendor js and css files.

The online tutorials kind of confuse me as a beginner in Webpack. So if someone could help me out in this particular use-case, it will help me better understand webpack in general.
I'm getting started with React 15. After going through tutorial and reading a few articles, I've come up with a few questions about the workflow. Here's how my index and webpack files look.

Here is my index.html file.
Does the compilation compile scripts like jquery.js, bootstrap.js and custom scripts for eg. script.js and include it in the compiled bundle.js?
In development, my images are located in src/assets/img/. I can't see the compiler copying assets into the dist folder.
From where do I set the relative paths for the CSS and JS files in index.html and the images within components? For eg. <img src="/assets/img/image.jpg"> OR <img src="/src/assets/img/image.jpg">
Thanks a lot for your time.
No in your case it won't be included in bundle.js because you are not using npm modules for bootstrap and jquery. You can try this way to include in your dev dependencies :
npm i -D bootstrap jquery
You don't need to copy assets to the dist folder. Webpack is a module bundler and everything you reference in your files will be included. You just need to specify a loader for that.For your reference :
How to copy static files to build directory with Webpack?
I don't really get the question but ofcourse you will set the path for css in the index.html for css you just have to import it with relative path. For example :
import App from './App'
