node-statvfs

This module implements statvfs function call

Installation

Install with npm:

npm install statvfs

Usage

The module exposes 3 functions.

• statvfs(path, callback): path should be a string and callback a function that takes an error and a statvfs object.
• statvfsAsync(path): returns a promise to return a statvfs object.
• statvfsSync(path): returns a statvfs object.

Those functions may throw errors containing the standards statvfs error code.

Examples

const {statvfs, statvfsAsync, statvfsSync } = require('node-statvfs');

// Callbacks
statvfs("/", (err, info) => {
    if (err) {
        console.log(err);
    }
    else {
        console.log(info);
    }
});

// Promise
async function getStat(path) {
  try {
    const info = await statvfsAsync(path);
    console.log(`blocks: ${info.f_blocks}`);
    return info
  } catch (err) {
    console.error(err)
    return 0
  }
}

statvfsAsync("/")
  .then(info => console.log(info))
  .catch(err => console.error(err))

// Synchronous
try {
  const info = statvfsSync("/");
  console.log(info);
}
catch (err) {
  console.log(err);
}
