I'm trying to get $ and jQuery to work in the DOM after loading them with webpack.
I will need jQuery for some extra dom manipulations that I will do with alongside video.js.
I've read through the webpack docs and this but although I can get jquery to work inside the bundle file with no problems, I can't seem to get it working outside of it.
My files in their current state:
webpack.config.js
var path = require('path');
var webpack = require('webpack');
module.exports = {
entry: './js/index.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist')
},
plugins : [
new webpack.ProvidePlugin({$: 'jquery',jQuery: 'jquery'})
],
};
index.html
<!DOCTYPE html>
<html>
<head>
<title>Webpack test</title>
</head>
<body>
<div id="playerContainer"> </div>
<script type="text/javascript" src="./dist/bundle.js"></script>
</body>
</html>
index.js
jQuery("body").css("background","red");
$("body").css("background","blue");
package.json
{
"name": "webpack-test",
"version": "1.0.0",
"description": "",
"main": "index.js",
"dependencies": {
"jquery": "^3.2.1"
},
"devDependencies": {
"webpack-dev-server": "^2.4.5",
"webpack": "^2.6.1"
},
"scripts": {
"start": "webpack -w",
"server": "webpack-dev-server"
},
"keywords": [],
"author": "",
"license": "ISC"
}
Is it possible to get jQuery (and maybe other libraries) to work in the browser?

I'm trying to run through the "Getting Started" section in Webpack's documentation here. I'm at the section before loading images - the .html file loads as expected ("Hello webpack" in red text) when I open it on Mozilla Firefox, but I get an Uncaught SyntaxError: Invalid or unexpected token (at bundle.js:2:8083) when I open it with Chrome. I'll include my index.js, dist/index.html, package.json, and webpack.config.js below:
index.js:
import _ from 'lodash';
import './style.css';
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());

},
module: {

};
Please let me know if you can figure out what I'm doing wrong! Thanks
I'm building a simple application using Tailwindcss, JavaScript & Webpack and trying to publish it via Github Pages.
While running the app via local host works fine, I am encountering a problem when trying to publish the app via gh-pages. I'm receiving the error message "404 File not found", why is that? Are there any dependencies missing in the webpack.config.js or package-json file?
Any help is appreciated.

You should add a "predeploy" in your package.json like so:
"predeploy": "npm run build"
and run it locally before you deploy to github pages.
source: https://dev.to/yuribenjamin/how-to-deploy-react-app-in-github-pages-2a1f
so I was following this https://webpack.js.org/guides/author-libraries/ from the web pack documentation, my file is just slightly different. No matter how I try to do this, I get various problems.
in my src/index.js file I have a simple function for example.
const Dinero = require('dinero.js')
export function calculateGrossRev(hudmonthly){
// Calculates the yearly gross rev
const hudonebr = Dinero({amount: hudmonthly, currency: 'USD'})
.multiply(12);
return hudonebr.getAmount();
}
In my package.json file I have.
{
"name": "library",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"build": "webpack",
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC",
"devDependencies": {
"dinero": "^1.0.1",
"lodash": "^4.17.21",
"webpack": "^5.51.1",
"webpack-cli": "^4.8.0"
},
"dependencies": {
"dinero.js": "^1.9.0"
}
}
In my webpack config file I have.
const path = require('path');
module.exports = {
mode: "development",
entry: './src/index.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'dinero-calc.js',
library: {
name: "dineroNumbers",
type: "umd",
},
},
};
when I run "npm run build", I get the big bundled file, all looks well to me.
I then have an index.html file I run with Live Server in VScode.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>TEST</title>
</head>
<h1>TEST</h1>
<script src="./dinero-calc.js"></script>
<script>
console.log(window.dineroNumbers.calculateGrossRev(8200));
</script>
<body>
</body>
</html>
With the simple example from the docs I'm able to get the expected output from their expected function printed to the console, however with my imported function it says
index.html:11 Uncaught TypeError: Cannot read property 'calculateGrossRev' of undefined at index.html:11
I think a problem is in the script source url <script src="./dinero-calc.js"></script>. Please, check paths of index.html and dinero-calc.js.
According to your script tag, they should be in the same directory under dist folder.
[Upd]
First, install dinero.js which used in src/index.js.
npm i dinero.js
Also, dinero should be placed in dependencies, not devDependencies, because dinero.js used in your code.
Second, call function like this
Dinero.default({
amount: hudmonthly,
currency: "USD",
}).multiply(12);
I don't seem to understand how webpack works. I would like to create a plain javascript library with some reusable components that I can use in other applications and in script tags in the html. So I tried to make a very simple library that exposes one variable containing a string. Should be simple I thought, but can't seem to get it to work.
My webpack.config.js:
const path = require('path');
module.exports = {
entry: './src/app.js',
output: {
filename: 'main.js',
path: path.resolve(__dirname, 'dist'),
library: {
name: 'mypack',
type: 'umd',
},
},
devtool: 'source-map',
devServer: {
watchContentBase: true,
contentBase: path.resolve(__dirname, 'dist'),
port: 9000
},
module: {
rules: [
{
test:/\.css$/,
use:['style-loader', 'css-loader']
}
]
},
}
My package.json:
{
"name": "mypack",
"version": "0.0.1",
"main": "./src/app.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "webpack --mode production",
"start": "webpack ./src/app.js -d eval --watch --mode development",
"dev": "npx webpack serve"
},
"author": "me",
"license": "ISC",
"devDependencies": {
"css-loader": "^6.0.0",
"webpack": "^5.44.0",
"webpack-cli": "^4.7.2",
"webpack-dev-server": "^3.11.2"
},
"dependencies": {
"style-loader": "^3.2.1"
}
}
My src/app.js
let myvar = "test";
export {myvar};
My dist/index.html:
<!doctype html>
<html>
<head>
<meta charset="utf-8"><title>test</title>
<meta name="viewport" content="width=device-width,initial-scale=1">
<script src="main.js"></script>
</head>
<body>
Test
<script>
console.log(mypack.myvar);
</script>
</body>
</html>
mypack.myvar gives an 'undefined' in the console. mypack seem to be an empty object {}.
How can I access myvar in my package? What am I doing wrong?
Of course, this is only a dummy, in reality I would like to expose objects from the package.
In the end it seems to be a problem with the webppack-dev-server.
If I comment out the line 'contentBase: path.resolve(_dirname, 'dist'),' from the webpack.config.js, copy the index.html to the root of my package and change the script tag source to "dist/index_bundle.js" then it works.
Not sure what is going on there, the script seems to load just fine in the situation above (in the sourceview in the browser, I can click the link and I see the generated javascript) but doesn't seem to be working at all. But that's another question.
I'm need to use webpack as a script (not the typical config file) and be able to support css imports, however webpack/style-loader does't seem to be able to load a css import when it's outside the root directory.
directoryA/package.json
{
"name": "poc",
"version": "1.0.0",
"description": "",
"main": "poc.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},

"dependencies": {
"style-loader": "^0.28.8",
"style-loader": "^0.19.1",

}
}
directoryA/poc.js
const path = require("path");
const webpack = require("webpack");
let appPath = process.env.PWD;
webpack({
entry: path.join(appPath, 'app.js'),
context: appPath,
output: {
libraryTarget: 'umd',
path: path.join(appPath, 'out'),
filename: 'app.js'
},
module: {
rules: [
{
test: /\.css$/,
use: ["style-loader", "css-loader"]
}
]
}
}).run(() => {
console.log("done");
});
directoryB/app.js
import './foo.css';
directoryB/foo.css
body { background-color: blue; }
directoryB/out/index.html
<html>
<head><script src="app.js"></script></head>
<body></body>
</html>
steps to replicate:
cd directoryB/
node ../directoryA/poc.js
then open directoryB/out/index.html in the browser
result: "Error: Cannot find module "./foo.css"
expected: loading css style and getting a blue page
Note that, if out/index.html , app.js and foo.cs are inside directoryA instead, then running node poc.js actually yields the expected result, however outside, webpack or style-loader can't seem to find the file (note: also tried to use the modules: directive. both cases work if using importing a js file)
