random-access-memory

Exposes the same interface as random-access-file but instead of writing/reading data to a file it maintains it in memory. This is useful when running tests where you don't want to write files to disk.

npm install random-access-memory

Usage

var ram = require('random-access-memory')
var file = ram()

file.write(0, Buffer.from('hello'), function () {
  file.write(5, Buffer.from(' world'), function () {
    file.read(0, 11, console.log) // returns Buffer(hello world)
  })
})

You can also initialize a ram instance with a Buffer:

var file = ram(Buffer.from('hello world'))
