Here is my current setup:
"typescript": "^4.1.3",
"webpack": "^5.11.0",
"webpack-cli": "^4.2.0"
"target": "ESNext",
"module": "ESNext",

rules: [
{
test: /\.tsx?$/,
exclude: /(node_modules|bower_components)/,
use: [
{
loader: "babel-loader",
options: {
presets: ["@babel/env"],
},
},
{
loader: "ts-loader",
},
],
},
],
