And instance a database?

[gusttavonl]

your can make this in your initial file from project, this example contain a route and config to use node and express

import express, { json, NextFunction, Request, Response, Router } from "express";
import "module-alias/register";
import "reflect-metadata";

export const cors = (req: Request, res: Response, next: NextFunction): void => {
  res.header("Access-Control-Allow-Origin", "*");
  res.header(
    "Access-Control-Allow-Headers",
    "Origin, X-Requested-With, Content-Type, Accept, Authorization"
  );
  res.header("Access-Control-Allow-Methods", "*");
  next();
};

export const contentType = (
  req: Request,
  res: Response,
  next: NextFunction
): void => {
  res.type("json");
  next();
};

export const initializeDb = (): void => {
  console.log("init your db instance"); // any database 
};

const router = Router()
Promise.all([initializeDb()])
  .then(async () => {
    const app = express();
    app.use(json());
    app.use(cors);
    app.use(contentType);
    app.use('/', router)
    app.listen(3000, () =>
      console.log(`The server is started!`)
    );
  })
  .catch((err) => console.log(err));
