Disk Statistics for NodeJS

... or ???

a wrapper adound statvfs

This library just wraps the statvfs system call, and returns all known details to the caller in a nice Promise.

import { statvfs } from '@juit/lib-statvfs'

// get the stats for our "/" (root) file system
const stats = await statvfs('/')

import { statvfs } from '../src/index'
// `stats` will now contain
// {
//   blocks_total: 1023659n,
//   blocks_free: 170084n,
//   blocks_available: 118826n,
//   blocks_used: 853575n,
//   bytes_total: 4192907264n,
//   bytes_free: 696664064n,
//   bytes_available: 486711296n,
//   bytes_used: 3496243200n,
//   files_total: 262144n,
//   files_free: 158621n,
//   files_used: 103523n,
//   percentage_used: 83.38,
//   percentage_free: 16.61
// }
