How to run multiple scripts in NodeJS?

Question

Node.js

Hello. It is necessary to launch the NodeJS server, which will simultaneously process API requests from the client, and in parallel, it is necessary to run a script that will run 1 time per second and make entries in the database. Is it possible to implement something like this?

pm2, different ports and all

Answer 2

Well, try to organize everything in the form of modules

• module1.js - server
  
• module2.js - database entries
  
• index.js - executable file
  

//module2.js
function module2() {
  console.log('module2 started);
  setTimeout(function () {
    setInterval(function () {
      console.log(('module2 timer:' + new Date().getTime()));
    }, 2000);
  }, 1000);
}

module.exports = module2;

//index.js
const module1 = require('./module1'),
          module2 = require('./module2');

module1();
module2();
