webpack 2.7 won't load blueprintjs core css - css

Question

I'm trying to use blueprintjs and when i'm importing its css. And i think i made something wrong in my webpack config so I see this error
there is my webpack config
const ExtractTextPlugin = require('extract-text-webpack-plugin');
var webpack = require("webpack");
var path = require("path");
module.exports={
entry: './src/index.js',
output:{
path: __dirname + "/public",
filename:'bundle.js',
publicPath: "/public/"
},
devServer: {
inline: true,
contentBase: './public',
port: 3000
},
module:{
rules: [
{
test: /\.js$/,
exclude: /(node_modules)/,
loader: "babel-loader",
query: {
presets: ['es2015', 'react', 'stage-0'],
}
},
{
test: /\.s(a|c)ss$/,
loader: ExtractTextPlugin.extract({loader: ['css-loader', 'sass-loader', 'style-loader']})
},
{
test: /\.css$/,
use: [
{
loader: 'style-loader',
},
{
loader: 'css-loader',
},
],
},
{
test: /\.(|gif||svg|woff|woff2|eot|ttf)(\?v=[0-9]\.[0-9]\.[0-9])?$/,
loader: 'file-loader', options: {name: '[name].[ext]'}
}, {
test: /\.(png|jpg|)$/,
loader: 'url-loader?limit=200000'
},
]
},
plugins: [
new ExtractTextPlugin("styles.css"),
]
}
i'm using "webpack": "^2.7.0","#blueprintjs/core": "^1.34.1" and a lot of loaders
i tried to import my css like this
require('!css-loader!./index.css');
and just like this
import styles from './index.css'
the result is the same
after extra couple hours of work i got this error
at this point i'm not sure what's wrong with my webpack and how to fix it at all
any suggestions are welcome

Answer 1

You can compare your webpack configuration with the one in the Blueprint monorepo: https://github.com/palantir/blueprint/tree/develop/packages/webpack-build-scripts
Try applying loaders in the same order as in the base config: ['style-loader', 'css-loader', 'sass-loader']

Answer 2

Try using the full path to blueprint.css inside the NPM package. The webpack error in the screenshot clearly shows the css-loader trying to load esm/index.js, a JS file, so of course it fails.
Try: #import "~#blueprintjs/core/lib/css/blueprint.css";
