node-ramdisk

(This repository is a fork of node-ramdisk). Our CI is on a windows machine, even though the application using this module are not running on windows. In order for us to be able to build it, we are removing the os targets of darwin and linux from the module's package.json.

If you need to use a library. Please refer to the original one at https://github.com/joaquimserafim/node-ramdisk.

create a ram disk with node.js

API

var ramdisk = require('node-ramdisk')

return a ramdisk object

ramdisk(volumeName)

var disk = ramdisk('my_ramdisk')

ramdisk#create(size[, callback(err, mount)])

• size - {integer} the size of the volume in MB
• callback - {function}
  • err - {Error} error message
  • mount - {string} the mounted block, in case of error is undefined

ramdisk#delete(volume[, callback(err, res)])

• mount - {string} the mounted block
• callback {function}
  • err - {Error} error message
  • res - {string} return 'ok' in case of success, in case of error is undefined

Note: delete will eject the volume and remove the mount folder

Usage

var ramdisk = require('node-ramdisk')
 
var disk = ramdisk('my_ramdisk')
 
var volumePoint
 
// create a disk with 100MB of size
disk.create(100, function (err, mount) {
  if (err) {
    console.log(err)
  } else {
    volumePoint = mount
    console.log(mount)
  }
})
 
// when isn't needed then delete the disk
disk.delete(volumePoint, function (err) {
  if (err) {
    console.log(err)
  } else {
    console.log('ok')
  }
})

Debug

DEBUG=node-ramdisk ...

Supported OS

• darwin (bad performance - is taking around 1 sec. to create the disk in my macbook pro mid 2012)
• linux (good performance - 20/30 mls to create the disk in a vagrant vm with few resources)
