How to fire an API call faster than the time/speed of cron jobs?

Do you mean that Laravel would not be a good fit for this purpose as the entire framework would boot each time?

As I need to save data to MySQL each time and perform some maths.

I see, so Laravel would not be a good fight for anything related to trading with exchanges then. Never used Node.js, question for you please.

Node.js is like a replacement of the PHP back end by a javascript kind of code. But can it still communicate with Mysql? Also, the demon with the intervals, do you initiate them directly within your code or it is something to setup on the server?

Thanks

nodejs is js. u need create project

# mkdir ololo
# cd ololo
# npm install mysql

and simple index.js in ololo dir

import mysql form 'mysql'

const connection = mysql.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
})

connection.connect()

setInterval(doJob, 500)

const doJob = () => {
	console.log('do job', new Date())
	connection.query('SELECT 1 + 1 AS solution', (error, results, fields) => {
  		if (error) throw error;
  		console.log('The solution is: ', results[0].solution);
	});
}

your script make mysql connection and execute doJob function every 500 ms

But this can be done via websockets and Laravel no? https://k6.io/docs/javascript-api/k6-ws/socket/socket-setinterval-callback-interval

What would be the difference? Any idea please? As you would still be using JS in the front end of Laravel.

Do you need this call to the API to be made even when nobody is looking at your site?

Yes as it is for trading. ie: I check a currency, based on the results, I send another request, and so on.

no, I don't think so

Wow! Perfect. I did not know about this package! Spatie thinks about everything :-)

They do, but developers misuse those packages.
