I have the following webpack config:
webpack.common.js:
const path = require('path');
module.exports = {
entry: './src/index.js',
watchOptions: {
ignored: [
path.resolve(__dirname, '.git'),
path.resolve(__dirname, 'node_modules'),
]
},
module: {
rules: [],
},
resolve: {
extensions: ['.js'],
},
output: {
filename: 'bundle.js',
path: path.join(__dirname, 'dist'),
publicPath: "/dist/",
},
};
webpack.dev.js:
const { merge } = require('webpack-merge');
const common = require('./webpack.common.js');
const HtmlWebpackPlugin = require('html-webpack-plugin')
module.exports = merge(common, {
mode: 'development',
devtool: 'inline-source-map',
devServer: {
open: true,
compress: false,
port: 9000,
http2: false,
https: false,
liveReload: true,
watchFiles: ['src/**/*'],
client: {
overlay: false,
},
static: {
directory: __dirname,
}
},
plugins: [
new HtmlWebpackPlugin({
template: './src/index.html',
})
]
});
My folder structure:
webpack.common.js
webpack.dev.js
src/
├─ index.html
├─ index.js
Tools versions:
"html-webpack-plugin": "^5.5.0"
"webpack": "^5.52.0"
"webpack-dev-server": "^4.1.0"
"webpack-merge": "^5.8.0"
QUESTION: When running webpack-dev-server --config webpack.dev.js in the root folder, I'm getting 404 error for index.html when accessing localhost:9000/index.html. Shouldn't index.html be created in memory?
I do get this in the log when starting the server:
asset bundle.js 901 KiB [emitted] (name: main)
asset index.html 5 KiB [emitted]
How not to get 404 error and access index.html that's in memory? Am I missing something?
Maybe this webpack config fix your problem, the index.html may be in a folder "public" and not in "src", and set enable the inject on index.html
Try this config :
const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
module.exports ={
mode: 'development',
entry: './src/index.js',
output: {
path: path.resolve(__dirname, 'dist'),
filename: 'index.js'
},
resolve: {
extensions: ['.js','.jsx']
},
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use:{
loader: 'babel-loader'
}
},
{
test: /\.html$/,
use:{
loader: 'html-loader'
}
},
{
test: /\.(css|scss)$/,
use:[
"style-loader",
"css-loader",
"sass-loader"
]
},
{
test: /\.svg$/,
use:{
loader: "svg-url-loader"
}
},
{
test: /\.png$/,
use: [
"file-loader",
{
loader: "image-webpack-loader"
}
]
}
]
},
plugins: [
new HtmlWebpackPlugin({
template: "./public/index.html",
inject:true,
filename: 'index.html'
}),
new MiniCssExtractPlugin(),
],
devServer:{
static: {
publicPath: path.join(__dirname, 'dist')
},
open:true,
compress: true,
port: 3000
}
}
My problem was with this line in webpack.common.js:
publicPath: "/dist/"
By removing it, it worked.
