Error: Cannot find module "." mongodb with webpack and typescript - node.js

Question

I have a problem when I can use mongoose with webpack. I already installed it as a dependency but when I want to use the mongoose object and execute it it commands me that it can not find the "." Module. And that seems very strange, I've been looking for a good time, I installed the dependencies again, delete the npm cache, reinstall webpack
I would appreciate your support, thank you very much
webpack.config.js
var path = require("path");
var typescriptLoader = {
test: /\.ts$/,
loader: 'ts-loader'
};
module.exports = {
entry: "./src/main.ts",
target: "node",
output: {
path: path.resolve(__dirname, "dist"),
publicPath: "dist/",
filename: "main.js"
},
node: {
__filename: true,
__dirname: true
},
watch: true,

},
module: {

Your mongoose is npm module. TypeScript may not recognized the way you import it. try the nodejs require module loading system.
var mongoose = require('mongoose');
or
const mongoose = require('mongoose');
