I thought it may be not having some of the loaders but that's not it.
Besides app.js does not compile in bundle.js too but it doesn't give a mistake. Maybe there is some mistake in entry but I don't know.
You need to include the SCSS file in your app.js (either require or import) and only pass your app.js file as entry for Webpack instead of passing the 2 files as entry.

I'm trying to import a PDF into a .js file in order to have a Click to open pdf into my render.
Importing
import myFile from './assets/files/myfile.pdf';
Rendering
render() {
return (
...
<a href={myFile}>
<span>Click to open PDF</span>
</a>
...
)}
Error

You may need an appropriate loader to handle this file type.

Webpack.config.js
I tried several PDF loader without success, the webpack below uses url-loader.
const path = require('path'),

Note: I'm testing this on localhost if that makes any difference.
SOLUTION
The problem came from the fact that I wasn't restarting the dev server by running npm run startdev after making some changes.
Include it in the file loader, as you do with images:
{ test: /\.(jpg|png|gif|svg|pdf)$/, use: [ { loader: 'file-loader', options: { name: '[name].[ext]', outputPath: './assets/images/' } } ] },
Note that I have added |pdf after the SVG declaration. Webpack should then process the file as it does with images.
config.module.rules.push({
test: /\.pdf$/,
use: {
loader: 'file-loader',
options: {
name: '[path][name].[ext]',
},
},
});
// vue.config.js configureWebpack
config.module
.rule('pdf')
.test(/\.pdf$/)
.use('pdf')
.loader('file-loader')
.end();
config.module
.rule('pdf')
.test(/\.pdf$/)
.use('file-loader?name=[path][name].[ext]')
.loader('file-loader')
.end();
I am experiencing annoying problem, when i run my react app in development environment it all works ok, but when i try to build to production, all the links are wrong.
assume this tree:
main_directory
public/
svg/
some_img.svg
src/
components/
some_component.jsx
App.js
index.js
Now in some_component.jsx i am referencing svg file in this way:
src="/public/svg/some_img.svg"
however after building to production this path is untouched and therefore cannot access file anymore, as there i would need it to be changed to this:
src="svg/some_img.svg"
i was playing in the webpack config file, i thought that maybe by setting:
publicPath: "/"
to:
publicPath: "/public/"
would resolve the problem but the only thing it did was error during application start:
CANNOT GET/
my webpack config:
const HtmlWebPackPlugin = require("html-webpack-plugin");
const htmlPlugin = new HtmlWebPackPlugin({
template: "./public/index.html",
filename: "./index.html"
});
module.exports = {
output: {
filename: "main.[hash:8].js",
publicPath: "/"
},
module: {
rules: [
{
test: /\.jsx$/,
exclude: /node_modules/,
loader: "babel-loader?presets[]=react"
},
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader"
}
},
{
test: /\.(sass|scss)$/,
use: ["style-loader", "css-loader", "sass-loader", "postcss-loader"]
},
{
test: /\.svg$/,
loader: "svg-sprite-loader"
}
]
},
plugins: [htmlPlugin],
devServer: {
historyApiFallback: {
rewrites: [{ from: /^\/$/, to: "/index.html" }]
}
},
resolve: {
extensions: [".js", ".jsx", ".json"]
}
};
How does one resolve this problem, so for both dev and production paths are unified?
How about importing the svg and then referencing the imported variable:
import someImg from "../../public/svg/some_img.svg"
src={someImg}
this is the solve for the question, config required for to specify path:
module: {
...
rules: [
{
test: /\.(png|jpg|gif|svg|ico)$/,
loader: 'file-loader',
query:{
outputPath: './img/',
name: '[name].[ext]?[hash]'
}
}
...
]
}
So right now I am having the issue I set up my webpack config as such
var webpack = require('webpack');
var path = require('path');
var parentDir = path.join(__dirname, '../');
module.exports = {
entry: [
path.join(parentDir, 'index.js')
],
module: {
rules: [{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
loader: 'babel-loader'
}, {
test: /\.less$/,
loaders: ["style-loader", "css-loader", "less-loader"]
}, {
test: /\.(png|woff|woff2|eot|ttf|svg)$/,
loader: 'url-loader?limit=100000'
}]
},
output: {
path: parentDir + '/dist',
filename: 'bundle.js'
},
devServer: {
contentBase: parentDir,
historyApiFallback: true
}
}
The error that I am getting is
Module parse failed: Unexpected character '#' (11:0)

| *

| #import url(https://fonts.googleapis.com/css?
family=Lato:400,700,400italic,700italic&subset=latin);/*!
I know I need to add a rule for this import I am just not sure which kind I am new to webpack and can't find anything referencing this type, also this #import exists in the semantic-ui-css package
Adding this bit to modules in the config file seemed to do the trick:
{
test: /\.css$/,
use: [
'to-string-loader',
'css-loader',
'resolve-url-loader'
]
}
I have webpack file that looks like this (note - for now - I need to create both minified and not minified versions of assets - so this is not a mistake):
const path = require('path');
const webpack = require("webpack");
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
const readSass = new ExtractTextPlugin({
filename: "foo/bar/style.min.css"
});
config = {
entry: {
"main": './main.js',
"main.min": './main.js',
"style.min": './style.scss'
},
watch: true,
devtool: "source-map",
output: {
path: path.resolve(__dirname, '/dist'),
filename: '[name].js'
},
module: {
rules: [
{
test: /\.jsx?$/i,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
presets: ['es2015', 'react'],
minified: true
}
},
{
test: /\.scss|css$/,
use: readSass.extract({
use: [{
loader: "css-loader", options: { minimize: true }
}, {
loader: "sass-loader"
}]
})
}
],
},
plugins: [
readSass,
new UglifyJsPlugin({
include: /\.min\.js$/
})
],
}
module.exports = config;
Everything works as expected, but there's one thing that bugs me.
In a few of my .jsx files I have CSS modules being loaded from different third-party components, stuff like:
import 'react-plugin/react-plugin.css';
Of course my compiled js and css files do not contain these styles. They're lost on the way. All the css from style.scss are there, all the js from main.js and jsx included within it are there, but theses styles are not.
What am I doing wrong?
that is simply because you are using extract-text-webpack-plugin module. if you want to keep your sass in your bundle then modify your webpack config into this:
const path = require('path');
const webpack = require("webpack");
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
config = {
entry: {
"main": './main.js',
"main.min": './main.js'
},
watch: true,
devtool: "source-map",
output: {
path: path.resolve(__dirname, '/dist'),
filename: '[name].js'
},
module: {
rules: [
{
test: /\.jsx?$/i,
loader: 'babel-loader',
exclude: /node_modules/,
options: {
presets: ['es2015', 'react'],
minified: true
}
},
{
test: /\.scss|css$/,
use: ['style-loader', 'css-loader', 'sass-loader']
}
],
},
plugins: [
readSass,
new UglifyJsPlugin({
include: /\.min\.js$/
})
],
}
module.exports = config;
and instal sass-loader and style-loader by this command: npm install -D sass-loader style-loader
EDIT: I forgot to tell you, you have to include your css or sass before your js entry point like this
require('path/to/your/main.scss')
ReactDOM.render(<App />, document.getElementById('root'))
so that it is bundled together AND you don't have to include your css in the webpack config entry point anymore.
The sass required not declare yet?it's possible to use ./sass/**/*.css/\ on your test to call any css style translate from sass.
Can you see what happens when you include style-loader too, like so:
$ npm i -D style-loader
//... webpack.config.js
{
test: /\.scss$/,
use: [{
loader: "style-loader"
}, {
loader: "css-loader"
}, {
loader: "sass-loader"
}],
exclude: /node_modules/
},
Edit: remove the exclude: /node_modules/ if you need to load files from there.
Then ensure you are importing it in your js entrypoint: import "../css/main.scss";

After running webpack i've got this error:
ERROR in ./assets/sass/main.scss

# ./index.js 3:0-34
Also i tried to use this loader: https://github.com/webpack-contrib/sass-loader
After webpack build there no errors appeared, but css file also was not created in /app folder.
file main.scss imports in index.js:
import './assets/sass/main.scss'
Can anyone give me an advice how can i build and watch scss files with webpack 3 ?
You have used some of the loader configs that suppose to be for webpack 1.
That section of the config:
loaders: [
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('style-loader',
'css?minimize!postcss!sass')
},
{
test: /\.(eot|woff|woff2|ttf|svg)(\?\S*)?$/,
loader: 'file?name=fonts/[name].[ext]'
},
{
test: /\.(jpg|jpeg|gif|png|svg)$/,
loader: 'file?name=images/[name].[ext]'
}
],
There are breaking changes when you move to Webpack 2 (or 3).
One of them was module.loaders => module.rules.
You will need to convert that section to the new structure.
In addition, ExtractTextPlugin changes it config style as well, please read it README.
