Images not loading Webpack/Webpack-dev-serve

all my images seem to be 404, I think I have the right path as I just stuck them in the root directory
I am using file loader and trying to load svg files
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const CleanWebpackPlugin = require("clean-webpack-plugin");
const webpack = require('webpack');
module.exports = {
entry: ["babel-polyfill", "./src/index.js"],
output: {
// filename and path are required
filename: "main.js",
path: path.resolve(__dirname, "dist")
},
module: {
rules: [
{
// JSX and JS are all .js
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
}
},
{
test: /\.(eot|svg|ttf|woff|woff2)$/,
use: [
{
loader: 'file-loader',
options: {}
}
]
}
]
},
plugins: [
new CleanWebpackPlugin(["dist"]),
new HtmlWebpackPlugin({
template: "./src/index.html"
}),
new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/),
]
};
here is an example I setup: https://github.com/chobo2/webpack-serve-example

You have to import:
import image from './Freesample.svg'
And use it like;
<img src={image}/>
But you also need an appropriate loader for it, another rule:
module.exports = {
entry: ["babel-polyfill", "./src/index.js"],
output: {
// filename and path are required
filename: "main.js",
path: path.resolve(__dirname, "dist")
},
module: {
rules: [
{
// JSX and JS are all .js
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
}
},
{
test: /\.(eot|svg|ttf|woff|woff2)$/,
use: [
{
loader: 'file-loader',
options: {}
}
]
},
{
test: /\.(png|jpg|jpeg|gif)$/,
loader: 'file-loader'
}
]
},
plugins: [
new CleanWebpackPlugin(["dist"]),
new HtmlWebpackPlugin({
template: "./src/index.html"
}),
new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/),
]
};

You need to use import.
import image from './Freesample.svg'
And use it like;
<img src={image}/>

webpack file-loader ouputting corrupted images

Am using the latest file-loader. It's outputting the files to images/css-urls like specified but they're corrupted images.
The config is searching through the sass files and replacing urls with new files that file-loader outputs. That part works, but the files are corrupted.
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const extractSass = new ExtractTextPlugin("./bundle.css");
var mainConfig = {
entry: {
"app": [
"./app/main.ts",
"./static/scss/main.scss",
],
"vendor": "./app/vendor.ts",
"polyfills": "./app/polyfills.ts",
},
output: {
path: path.resolve(__dirname, "static"),
filename: "[name].js"
},
resolve: {
extensions: [".ts", ".js"],
},
devtool: "source-map",
module: {
rules: [{
test: /.*\.(gif|png|jpe?g|svg)$/i,
use: [
{
loader: 'file-loader',
options: {
name: '[name].[hash].[ext]',
outputPath: 'images/css-urls/',
}
},
]
}, {
test: /\.(scss|css)$/,
use: extractSass.extract({
use: [{
loader: "css-loader",
}, {
loader: "sass-loader",
}],
// use style-loader in development
fallback: "style-loader"
})
}, {
test: /\.(png|jpg|gif|svg|eot|ttf|woff|woff2)$/,
loader: "url-loader",
}, {
test: /\.ts$/,
loaders: [
{
loader: "awesome-typescript-loader",
options: { configFileName: root("./", "tsconfig.json") }
} , "angular2-template-loader"
]
}, {
test: /\.html$/,
loader: "html-loader"
}]
},
plugins: [
extractSass,
new webpack.ContextReplacementPlugin(
// The (\\|\/) piece accounts for path separators in *nix and Windows
/angular(\\|\/)core(\\|\/)#angular/,
root("./app"), // location of your src
{} // a map of your routes
),
new webpack.optimize.CommonsChunkPlugin({
name: ["app", "vendor", "polyfills"]
}),
]
}

I got it to work by removing the file-loader rule and replacing the url-loader rule with this
{
test: /\.(png|jpg|gif|svg|eot|ttf|woff|woff2)$/,
loader: "url-loader",
options: {
limit: 8192,
fallback: "file-loader",
// fallback options
name: '[name].[hash].[ext]',
outputPath: 'images/css-urls/',
},
}

Extract specific CSS files to a file with Webpack

What I'm trying to achieve is a Webpack configuration where CSS is handled by the final JS export, but, some specific files are exported to an external file (to optimize critical CSS loading).
So, the idea is: if the file name start with _critical-, put it in a file.
So, here is my webpack.config.js for the moment:
const path = require('path');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: './src/entry.js',
output: {
path: path.join(__dirname, 'public'),
filename: 'bundle.js'
},
module: {
rules: [
{
loader: 'babel-loader',
test: /\.js$/,
exclude: /node_modules/
},
{
use: [
'style-loader',
'css-loader',
'sass-loader'
],
test: /\.s?css$/,
},
{
use: ExtractTextPlugin.extract({
fallback: 'style-loader',
use: [
'css-loader',
'sass-loader'
]
}),
test: /\A_critical-.*\.s?css$/,
},
{
test: /\.(png|jp(e*)g|svg)$/,
use: [{
loader: 'url-loader',
options: {
limit: 10000,
name: 'images/[hash]-[name].[ext]'
}
}]
}
]
},
plugins: [
new ExtractTextPlugin("styles.css"),
],
devtool: 'cheap-module-eval-source-map',
devServer: {
contentBase: path.join(__dirname, 'public'),
historyApiFallback: true
}
};
And, at some point, I have import './components/base/_critical-color.scss'; in my code.
When I run Webpack, no error. But no styles.css either.
What am I missing?

webpack does not output css

Situation
I have a webpack setup, where I have a rule that extracts CSS and/or SASS from .ts files using the extract-text-webpack-plugin and sass-loader.
I import my SCSS file in a seperate .ts file
import './scss/style.scss'
Problem
A CSS file is expected to be in the output folder ( dist ).
The compilation completes without an error, yet there is no CSS file in the build folder.
Here is my webpack configuration:
var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var styleString = require('css-to-string-loader');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
const extractSass = new ExtractTextPlugin({
filename: "[name].css",
disable: process.env.NODE_ENV === "development"
});
var helpers = require('./helpers');
var isProd = process.env.NODE_ENV === 'production';
module.exports = {
entry: {
polyfills: './src/polyfills.ts',
vendor: './src/vendor.ts',
app: isProd ? './src/main.aot.ts' : './src/main.ts'
},
resolve: {
extensions: ['.ts', '.js']
},
module: {
rules: [{
test: /\.ts$/,
loaders: [
'babel-loader',
{
loader: 'awesome-typescript-loader',
options: {
configFileName: isProd ?
helpers.root('tsconfig-aot.json') :
helpers.root('tsconfig.json')
}
},
'angular2-template-loader'
],
exclude: [/node_modules/]
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/,
query: {
presets: ['es2015']
}
},
{
test: /\.html$/,
loader: 'html-loader'
},
{
test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
loader: 'file-loader?name=assets/[name].[ext]'
},
{
test: /\.(json)$/,
loader: 'file-loader?name=assets/mocks/[name].[ext]'
},
{
test: /\.(css|scss)$/,
loaders: ['to-string-loader', 'css-loader', 'sass-loader']
}
]
},
plugins: [
// Workaround for angular/angular#11580
new webpack.ContextReplacementPlugin(
// The (\\|\/) piece accounts for path separators in *nix and Windows
/angular(\\|\/)core(\\|\/)#angular/,
helpers.root('./src'), // location of your src
{} // a map of your routes
),
new webpack.optimize.CommonsChunkPlugin({
name: ['app', 'vendor', 'polyfills']
}),
new HtmlWebpackPlugin({
template: 'src/index.html'
})
]
};

Reason
The reason there is not output CSS file is because you are not using the
const extractSass = new ExtractTextPlugin({
filename: "[name].css",
disable: process.env.NODE_ENV === "development"
});
in your CSS|SCSS rule
{
test: /\.(css|scss)$/,
loaders: ['to-string-loader', 'css-loader', 'sass-loader']
}
Solution
You have to make use of the use property like so:
{
test: /\.(css|scss)$/,
use: extractSass.extract({ // <==== Right here, note the "extractSass"
use: [
{ loader: "to-string-loader" },
{ loader: "css-loader" },
{ loader: "sass-loader" }
],
fallback: "style-loader"
})
}
And add to your plugins array the ExtractTextPlugin instance ( extractSass ):
plugins: [
extractSass
]

Sourcemap Sass with Webpack (2)

I am using Webpack 2 for building my Angular (4) app. I have it working, but I am trying to figure out how to generate sourcemaps for my scss. In my components I load my scss with styleUrls Adding the options: { sourceMap: true } is not working. I do not want to extract the styles for components, because then the ViewEncapsulation is not working anymore. The .global.scss I use are needed everywhere, so I do extract these and this part works fine. Can someone tell me how to generate my sourcemaps (is it even possible with Angular)? Below is my webpack.config.js .
const webpack = require('webpack');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const autoprefixer = require('autoprefixer');
const path = require('path');
module.exports = {

},

},

path: path.join(__dirname, '../www/'),
