Webpack Dev Server (Uncaught SyntaxError: Unexpected token '<' ) - webpack-dev-server

Question

Building TS/SASS with Webpack works fine, running this through VSCode Live Server plugin renders the index.html perfectly to the app folder.
Running webpack-dev-server with it looking at the same app folder does not. The page opens but there is a Javascript error Uncaught SyntaxError: Unexpected token '<'
And the page does not render the JS/CSS.
webpack.config.js
// Imports
var path = require("path");
// Plugins
const HtmlWebPackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
// Exports
module.exports = {
mode: 'development',
entry: './src/main.ts',
devtool: "inline-source-map",
resolve: {
extensions: [".ts", ".tsx", ".js"]
},
output: {
filename: 'main.min.js',
path: path.resolve(__dirname, 'app')
},
devServer: {
open: 'http://localhost',
port: 80,
publicPath: path.resolve(__dirname, 'app'),
hot: true
},
module: {
rules: [
{
test: /\.ts$/,
use: 'ts-loader',
},
{
test: /\.html$/,
use: [
{
loader: 'html-loader',
options: { minimize: true }
}
]
},
{
test: /\.(png|svg|jpg|gif)$/,
use: [
'file-loader'
]
},
{
test: /\.scss$/,
use: [
"style-loader",
"css-loader",
"sass-loader"
]
},
]
},
plugins: [
new HtmlWebPackPlugin({
template: "./src/index.html",
filename: "./index.html"
}),
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename: "[id].css"
}),
]
}
tsconfig.json
{
"compilerOptions": {
"sourceMap": true
}
}
main.ts
console.log('Main.ts has loaded')
import './styles/main.scss'
Any help with this would be appreciated, I'm losing my mind lol.

My issue was with syntax in the webpack.config.js file.
I was neglecting to insert a comma at the end of the last entry in every object and array, believing it not to be necessary.
Here is a working config:
// Imports
var path = require("path");
// Plugins
const HtmlWebPackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
// Exports
module.exports = {
mode: 'development',
entry: './src/main.ts',
devtool: "inline-source-map",
output: {
filename: 'main.min.js',
path: path.resolve(__dirname, 'app'),
},
devServer: {
open: 'http://localhost',
port: 80,
},
module: {
rules: [
{
test: /\.ts$/,
use: 'ts-loader',
},
{
test: /\.html$/,
use: [
{
loader: 'html-loader',
options: { minimize: true },
}
]
},
{
test: /\.(png|svg|jpg|gif)$/,
use: [
'file-loader',
]
},
{
test: /\.scss$/,
use: [
"style-loader",
"css-loader",
"sass-loader",
]
},
]
},
plugins: [
new HtmlWebPackPlugin({
template: "./src/index.html",
filename: "./index.html",
}),
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename: "[id].css",
}),
]
}
