angular shows error : webpack CLI failed to load

I am trying to create my react application from scratch but my webpack.config.js is giving me errors saying [webpack CLI ] failed to load
Below is the webpack.config.js code
const HtmlWebPackPlugin = require(“html-webpack-plugin”);
const htmlPlugin = new HtmlWebPackPlugin({
template: “./src/index.html”,
filename: “./index.html”
});
module.exports = {
mode: ‘development’,
module: {
rules: [{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: “babel-loader”
}
},
{
test: /\.css$/,
use: [“style-loader”, “css-loader”]
}
]},
plugins: [htmlPlugin]
};
Above is the code giving me errors in the webpack.config.js

Webpack cannot read property 'Blob' of undefined

Entry file will build literally just fine, but the error occurs on client side, which makes the whole bundle file doesn't work with this issue Uncaught TypeError: Cannot read property 'Blob' of undefined
and i have attached the webpack.config.js which i have tried too
const path = require('path')
const webpack = require('webpack')
const HtmlPlugin = require('html-webpack-plugin')
const ExtractTextPlugin = require('extract-text-webpack-plugin')
const config = {
entry: './src/main-entry.js',
output: {
path: path.resolve(__dirname, 'views/dist'),
filename: 'bundle.js'
},
module: {
rules: [
{ test: /\.(png|woff|woff2|eot|ttf|svg|gif)$/, loader: 'url-loader?limit=100000' },
{
test: /\.css$/,
use: ExtractTextPlugin.extract({
use: 'css-loader', fallback: 'style-loader'
})
},
{
test: /\.js$/,
loader: 'babel-loader',
exclude: /node_modules/
}
]
},
plugins: [
new ExtractTextPlugin('bundle.css'),
new webpack.optimize.UglifyJsPlugin({
include: /\.min\.js$/,
minimize: true
})
]
}
module.exports = config
I am using webpack latest version. But i don't know why this is happening? can you help me?

angular2 bundle node_modules only and not application code

Angular v.4 and webpack
i am looking for answer of very simple question.
How can i bundle node_module folder as vendor.js but not your application code. on page load seems like there are more then 300 requests from angular code to load internal files.
if i am able to merge all node_modules libraries i will save lot of browser requests.
I followed this example was able to get it run but it bundles libraries and your application code as well. i was able to successfully generate the vendor.js only but i am not sure after i add vendor.js in index.html how my application code will recognize #angular lib references. currently it is being resolved using systemjs.config.js some thing like this
#angular/code : 'npm:#angular/code/bundle/core.umd.js'
..
..
and exactly thats what happen as i thought application crashed it can't find references to #angular from my application code.
is it possible to just bundle node_module folder into vendor.js and still able to use in my application code without bundling app code ?

Waypoint npm - Error: Can't resolve 'waypoint

I have a vue project and installed waypoints
npm install waypoints
I try to import it
import waypoint from 'waypoints';
but get an error

Waypoints comes bundled in several flavours, even via NPM, but I couldn't work out if there's a default implementation or not. So that's why your typical import Waypoint from 'waypoints' directive doesn't work.
I resolved this for my "vanilla ES6 + Webpack" setup as follows:
import 'waypoints/lib/noframework.waypoints.min.js';
const waypoint = new Waypoint({
element: document.getElementById('myScrollTarget'),
handler: () => {}
});

Basically #markedup is right, waypoints comes with various flavours, after installing waypoints if you look into /waypoints/lib/ folder you will see zepto|jquery|noframework.waypoints.js .
In this case you would require to import it as full path i.e.
import 'waypoints/lib/noframework.waypoints.min.js';
or
window.waypoint = require('waypoints/lib/noframework.waypoints');

No such file or directory error in Webpack + highlight module

I'm working on an Electron app which requires the code highlighting feature. I installed highlight module as a node dependency and use webpack to bundle all the code into the app.bundle.js.
However, when I launch the Electron app, I notice an error from the highlight module complaining
Uncaught Error: ENOENT: no such file or directory, scandir '//vendor/highlight.js/languages/'
Inside app.bundle.js, the highlight module still uses the vendor/highlight.js/languages/ to search for its utilities files which I thought should be included into app.bundle.js with their paths updated.
var Highlight = module.exports
, fs = __webpack_require__(336)
, hljs = __webpack_require__(408).hljs
, langRelPath = "vendor/highlight.js/languages/"
, langPath = __dirname + "/" + langRelPath
, reEndsWithJs = /\.js$/i
, loadedMap = {}
, availableMap = {}
;
It's my first time to use webpack, so it might be caused by some webpack misconfigurations. I paste the webpack.config.js for your convenience.
'use strict'
const path = require('path');
const webpack = require('webpack');
module.exports = {
entry: [
'./app/app.js'
],
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'app.bundle.js'
},
module: {
loaders: [{
test: /\.js$/,
include: [path.resolve(__dirname, 'app')],
exclude: /node_modules/,
loaders: ['babel?presets[]=es2015,presets[]=react']
}, {
test: /\.(scss|css)$/,
loaders: ['style', 'css', 'sass']
}, {
test: /\.json/,
loader: 'json'
}, {
test: /\.(png|jpg)$/,
loader: 'url-loader'
}, {
test: /\.html$/,
loader: 'html'
}, {
test: /\.txt$/,
loader: 'text'
}]
},
target: 'electron'
};
Does anyone have some idea for this?
（Everything works fine when not bundle by webpack.）
Thank you in advance:)
