Boilerplate to start an Express server and connect to MongoDB using Mongoose

server.ts

import * as express from "express";
import * as mongoose from "mongoose";

const app = express();

const uri = "mongodb://localhost:27017/test"; // replace with your URI

mongoose
  .connect(uri, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useFindAndModify: false,
    useUnifiedTopology: true
  })
  .then(() => console.log("Connected to MongoDB"))
  .catch((e: Error) => console.error(e));

const port = 5001;

app.listen(port, () => {
  console.log(`Server started on http://localhost:${port}`);
});
