Get the amount of total memory available in bytes

Get the amount of total memory available in bytes (as integer): os.totalmem()

The os module has the totalmem() method to return information on the total memory available in the system. The totalmem() function returns an integer and it represents the bytes. If you need megabytes or kilobytes you have to convert it.

import { totalmem } from 'os'
const mem = totalmem()
console.log(
  'Hi, the total memory is %d gigabytes',
  mem / 1024 / 1024 / 1024
)
