Extract text plugin specify input folder webpack - javascript

config.module.rules.push({
test: /\.css$/,
include: [
path.resolve(__dirname, 'static/styles/vendor'),
],
use: ExtractTextPlugin.extract({
loader: 'css-loader',
}),
});
config.plugins.push(new ExtractTextPlugin('/static/styles/vendor/foundation.css'));
unable to get the exact folder to loop over , if I exclude the include option it creates an output file with all css of the app
Directory structure

ExtractTextPlugin works only for files imported in your javascript. Are you sure your static content is imported in any of your js file?

How to load CSS files with webpack

Im trying to have my CSS file in the src folder copied into the dist folder on build - Im currently using a HTML file in my dist - ie im not using a javascript file so dont want the styles to be created as javascript.I just need the files to be copied into the dist. Heres my current config that isnt working.
const htmlWebpackPlugin = require('html-webpack-plugin')
module.exports = {
devServer:{
port:8000
},
module: {
rules: [
{
test: /\.html$/i,
loader: 'html-loader',
},
{
test: /\.css$/i,
use: [ 'style-loader','css-loader'],
},
{
test: /\.(png|jpe?g|gif|glb|gltf|typeface.json)$/i,
loader: 'file-loader',
options: {
publicPath: './',
name: '[name].[ext]'
},
},
]
},
plugins: [
new htmlWebpackPlugin({
template: './src/index.html',
filename: './index.html'
})
]
}
I then use a link tag to add the css into the index.html file eg
<link rel="stylesheet" href="./style.css">
But this just adds javascript to the HTML file it builds in the dist.
How can i do this?
***EDIT: Im trying to add CSS files without merging them into my Javascript files
You can try using MiniCssExtractPlugin. As written in the documentation:
This plugin extracts CSS into separate files. It creates a CSS file per JS file which contains CSS. It supports On-Demand-Loading of CSS and SourceMaps.
To use it, you can first install it, import it, add a loader and a plugin to your webpack config. Here's an example (don't forget to note the order must be correct):
...
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports = {
...
module: {
rules: [
...
{
test: /\.css$/i,
use: ['style-loader', MiniCssExtractPlugin.loader, 'css-loader'],
},
...
],
},
plugins: [
...
new MiniCssExtractPlugin(),
],
};
It will also add an automatic link tag to your css files in index.html results.

HTML Webpack Plugin not creating correct index.html file

I am using HTMLWEBPACKPLUGIN to create an html file in the dist folder. I am using the template option of the plugin so that i can add a div in the html file for the root div where my react components will be injected.
Strangely, a hashed file is created with the correct code, and another file, index.html file is created with the name of the other file and the script junction to the bundle.js file instead of having one single html file
webpack.config.js File :
var HtmlWebpackPlugin = require('html-webpack-plugin');
module.exports = {
mode: "none",
entry: "./src/index.tsx",
output: {
filename: "bundle.js",
path: __dirname + "/dist"
},
plugins: [new HtmlWebpackPlugin({template: './src/index.html'})],
// Enable sourcemaps for debugging webpack's output.
devtool: "source-map",
resolve: {
// Add '.ts' and '.tsx' as resolvable extensions.
extensions: [".ts", ".tsx", ".js", ".json"]
},
module: {
rules: [
// All files with a '.ts' or '.tsx' extension will be handled by 'awesome-typescript-loader'.
{
test: /\.tsx?$/,
loader: "ts-loader",
options:
{
configFile: 'tsconfig.client.json'
} ,
exclude: /node_modules/
},
// All output '.js' files will have any sourcemaps re-processed by 'source-map-loader'.
{
enforce: "pre",
test: /\.js$/,
loader: "source-map-loader" ,
exclude: /node_modules/
},
{
test: /\.html$/,
loader: "file-loader",
exclude: /node_modules/
},
]
},
};
index.html file :
31b0c63f79c4c085d45b3861fe75d263.html<script type="text/javascript" src="bundle.js"></script>
hashedFile.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Webpack App</title>
</head>
<body>
<div id="root"></div>
<script type="text/javascript" src="bundle.js"></script></body>
</html>
It's happening because you configured webpack to use file loader for html files.
The template plugin renders the file by importing it using a loader. By default, the loader returns the file contents. By using the file-loader, webpack thinks you want to obtain the url for the html file instead of it's content when the html webpack plugin renders index.html.
Maybe you can configure an include directory for the html plugin configuration for the source files, something like
{
test: /\.html$/,
loader: "file-loader",
include: path.resolve(__dirname, 'src')
}
You need to configure a name for your files: https://webpack.js.org/loaders/file-loader/#options
Check out 'name' in the table. It defaults to [hash].[ext]. If you want the name to remain the same as the actual file, set options: { name: '[name].[ext]' } in your file-loader webpack configuration.
Doc for setting name with a string: https://webpack.js.org/loaders/file-loader/#-string-

CSS images not copied to output folder in Webpack

I am using Webpack to bundle a number of js/css files in a site. I am bundling bootstrap.css and chosen.css as part of my bundles. In order to create the bundles, I have a main.js that I am using as an entry point to import all the other files that I will need. I am using file-loader to process font and image files and move them to the appropriate directories. I am using the ExtractTextPlugin with the css-loader and resolve-url-loader to create a separate css bundle from my js bundle.
My main.js is:
import 'bootstrap/dist/css/bootstrap.css';
import 'chosen-js/chosen.css';
import './datetimehelper.js';
import './deletelink.js';
import './dropdown.js';
My webpack.config.js is:
var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {
entry: './src/js/main.js',
output: {
filename: 'wwwroot/js/bundle.js'
},
module: {
rules: [
{
test: /\.js$/,
exclude: /(node_modules|bower_components)/,
use: {
loader: 'babel-loader',
options: {
presets: ['#babel/preset-env']
}
}
},
{
test: /\.(png|jpg|gif)$/,
use: [
{
loader: 'file-loader',
options: {
name: 'images/[name].[ext]',
outputPath: 'wwwroot/'
}
}
]
},
{
test: /\.(eot|svg|ttf|woff|woff2)$/,
use: [
{
loader: 'file-loader',
options: {
name: 'fonts/[name].[ext]',
outputPath: 'wwwroot/'
}
}
]
},
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
use: ['css-loader?url=false', 'resolve-url-loader'],
publicPath: '../'
})
}
]
},
plugins: [
new ExtractTextPlugin({
filename: 'wwwroot/css/bundle.css'
})
]
};
With the above configuration, the font references in bootstrap.css are picked up, moved to the appropriate directory and the urls are fixed in the css bundle that is emitted. However, the images that are referenced in chosen.css are not being picked up. Can anyone tell me what I need to do to make the images work correctly? I've tried replacing file-loader with url-loader and no change. I've also tried importing the images in my main.js and they were moved, but the urls in the css bundle were not rewritten correctly.
Having path configured in output makes life a lot easier. That would serve as the base output folder and all other loaders/plugins can work relative to that. May be the files were copied but not to your intended directory. Please do take a look at WebpackBootstrap repo. The config copies as well as converts image paths properly.
I finally figured it out. In the rules, I had:
{
test: /\.css$/,
use: ExtractTextPlugin.extract('css-loader', 'resolve-url-loader')
}
Instead, it should be:
{
test: /\.css$/,
loader: ExtratTextPlugin.extract('css-loader', 'resolve-url-loader')
}
Not sure what the difference is between use and loader because I'm fairly new to Webpack, but in this case it makes all the difference.

How to include all CSS files in node_modules to be built by css-loader?

I am trying to extract all the CSS files found in the node_modules directory into a single file. My Webpack config is as follows:
{ // node_modules css in /node_modules/**/*.css
test: /\.css$/,
include: /node_modules/,
// extract to the node modules css file
use: ExtractTextPluginNodeMods.extract({
fallback: 'style-loader',
use: [
{
loader: 'css-loader',
options: {
modules: false,
},
},
],
}),
}
Unfortunately, none of the CSS files in the node_modules directory are being bundled into the file specified with ExtractTextPluginNodeMods. I have another ExtractTextPlugin instance that is successfully extracting CSS from my src directory. Any idea why I cannot get extraction of CSS from node_modules?
For reference, my other ExtractTextPlugin/Webpack config (which is bundling all of my CSS is here:
{
// OUR css in /src/
// the css output from sass loader will be caught here
// fonts are imported by css loader
// after transpiling of sass -> css, css-loader in webpack should take care of this
// https://github.com/webpack-contrib/css-loader
test: /\.css$/,
exclude: /node_modules/,
// extract to our css file
use: ExtractTextPluginSrc.extract({
fallback: 'style-loader',
use: [
{
loader: 'css-loader',
// create modular css with the '[name]__[local]___[hash:base64:5]'
options: {
modules: true,
localIdentName: '[name]__[local]___[hash:base64:5]',
},
},
'postcss-loader',
],
}),
}
Webpack won't include the CSS files unless you explicitly import them from your javascript code. So you'll need:
import 'some_package/css/component.css';
in the part of your app that uses the CSS.
Alternatively you could use something like glob-loader to do
import 'glob-loader?node_modules_pattern_file';
and then have your "node_modules_pattern_file" include a glob like
../node_modules/**/*.css
...but I don't recommend this approach because you'll end up pulling in loads of files you don't need and it will be hard to maintain.

Webpack sass where is the css file

I am using web pack with sass loader like this:
module.exports = {
module: {
loaders: [
{
test: /\.scss$/,
loader: "style!css!sass"
}
]
}
};
But i see the styles apply to the style tag, where is the generate css file?
By default, the style-loader inlines the compiled css into your bundle, which are added to the head of the page with the output file e.g. bundle.js. Using the extract-text-webpack-plugin you can remove the compiled css from the bundle, and export it to a separate file.
First - wrap your loader in the plugin:
loaders: [{
test: /\.scss$/,
loader: ExtractTextPlugin.extract(
"style",
"css!sass")
}]
},
Then tell the plugin what to call the file it generates:
plugins: [
new ExtractTextPlugin("app.css")
]
Include this file in your HTML normally.
If you want a separate CSS file when using Webpack, you need to use the extract-text-webpack-plugin.
The extract-text-webpack-plugin has been deprecated you should use the mini-css-extract-plugin. Assuming you have your styles in css/app.scss, your entry file should import it as usual like:
import 'css/app.scss';
Add the plugin:
plugins: [new MiniCssExtractPlugin()]
And add the plugin to your loader chain:
{
test: /\.s[ac]ss$/i,
use: [MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader']
}
When you run webpack with that configuration you'll end up with an app.css file loaded in your HTML with a tag similar to:
<link href="app.css" rel="stylesheet">
