i am using this webpack project template from here
to run it i use npm run serve .how can I add auto build/serve when files are changed. is it something to do with webpack or npm? .i am new to this javascript tooling & searching on google gives lots of options which is overloaded with information & configurations each different.
attaching the webpack config:
const path = require('path')
const webpack = require('webpack')
module.exports = env => {
return {
entry: {
main: './src/index.js'
},
output: {
filename: 'bundle.js',
path: path.join(__dirname, 'dist'),
publicPath: "/"
},
mode: env && env.production ? 'production' : 'development',
module: {
rules: [
{
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: 'babel-loader',
options: {
presets: ['env']
}
}
},
{
test: [/\.vert$/, /\.frag$/],
use: 'raw-loader'
}
]
},
devServer
: {
contentBase: './dist'
},
plugins: [
new webpack.DefinePlugin({
'CANVAS_RENDERER': JSON.stringify(true),
'WEBGL_RENDERER': JSON.stringify(true)
})
]
}
}

I have my webpack watch all my files using watch: true in webpack.config.js.
I run webpack using npm run build through this code in package.json:
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"build": "webpack"
},
Now when I use npm run build, it only compiles every time I save package.json. How do I change it so that it compiles every time I save a file in all of my folders?

Use the command in your package.json
webpack --watch --config webpack.config.js
To fix this, add cache: false in the HTMLWebpackPlugin object argument in webpack.config.js:
plugins: [
new webpack.DefinePlugin({
'global': {}
}),
new HtmlWebpackPlugin({
inject: "body",
template: './src/ui.html',
filename: 'ui.html',
chunks: ['ui'],
cache: false // Add this line
}),
new InlineChunkHtmlPlugin(HtmlWebpackPlugin, [/ui/]),
],
So i'm pretty new to Webpack, and I finally got the webpack-dev-server running. It recompiles and refreshes page on save, and it shows changes to my JS code. But it doesn't seem to work well with my SASS or HTML files?
On a fresh start, it will show a change if I make it, but if I undo that change, it doesn't update. Looking around other posts, I tried added the "--hot" flag, and adding "inline" to my devServer in webpack config. This got it working for a style change, but won't show deleted or undone changes.
This is my package.json...

I must have something wrong or out of place?
Any help or tips would be appreciated. Will provide additional info if needed.
Thanks in advance!
I found a solution by adding "watchContentBase" to my devServer.
devServer: {
contentBase: path.resolve(__dirname, 'dist'),
**watchContentBase: true,**
inline: true,
hot: true
}
When I run npm run build only generate build.js on dist directory this are my package.json and my webpack configuration. I dont know if doing something wrong with my configuration of webpack or with my package configuration

I needed to generate all the files to deploy to the server but only generate build.js
I am trying to make an ajax request using fetch to an api. When I run npm build I get this error
ERROR in ./src/js/index.js 14:7
Module parse failed: Invalid regular expression flag (14:7)
You may need an appropriate loader to handle this file type.

What other module do I have to add so that I can make use fetch? I am using fetch to access a local api server in the same directory as my front end webpack files, could this be causing the issue too?
Why does Hot Module Replacement stop working on webpack dev server?

"webpack-dev-server": "^1.14.1"
}
}
I have also set:
devserver = {
historyApiFallback: true,
inline: true,
hot: true
}
But it didn't helped.
webpack.config.js file:
var webpack = require('webpack');
var path = require('path');
var DIST_DIR = path.resolve(__dirname, 'dist');
var SRC_DIR = path.resolve(__dirname, 'src');
var config = {
devServer: {
historyApiFallback: true,
contentBase: './',
inline: true,
hot:true,
port: 3004,
},
entry: SRC_DIR + '/app/index.js',
output: {
path: DIST_DIR + '/app',
filename: 'bundle.js',
publicPath: '/app/'
},
module: {
loaders: [
{
test: /\.js?/,
include: SRC_DIR,
loader: 'babel-loader',
query: {
presets: ['react', 'es2015', 'stage-2']
}
},
{
test: /\.css?/,
loader:'style-loader!css-loader'
},
]
}
};
module.exports = config;
Previously I had CSS loaders issue and after adding loaders in webpack.config.js I got webpack stopped.
how can I make Hot module work?
You need to activate the Hot Module Replacement Plugin, full instructions: https://webpack.js.org/guides/hot-module-replacement/
