with-open-file

with-open-file

Do stuff with an open file, knowing it will finally be closed

Because the built-in way requires way too much boilerplate.

Install

$ npm install with-open-file

Usage

const fs = require('fs-extra')
const withOpenFile = require('with-open-file')

const buf = Buffer.alloc(5)

withOpenFile('foo.txt', 'r', fd => {
  return fs.read(fd, buf, 0, buf.length, 0)
})
//=> { bytesRead: 5, buffer: ... }

withOpenFile.sync('foo.txt', 'r', fd => {
  return fs.readSync(fd, buf, 0, buf.length, 0)
})
//=> 5
