random-access-idb

random-access-compatible indexedDB storage layer

example

var random = require('random-access-idb')('dbname')
var cool = random('cool.txt')
cool.write(100, new Buffer('GREETINGS'), function (err) {
  if (err) return console.error(err)
  cool.read(104, 3, function (err, buf) {
    if (err) return console.error(err)
    console.log(buf.toString()) // TIN
  })
})

api

var random = require('random-access-idb')

var db = random(dbname, opts)

Open an indexedDB database at dbname.

Any opts provided are forwarded to db(name, opts) as default options.

var file = db(name, opts)

Create a handle file from name and opts:

  • opts.size - internal chunk size to use (default 4096)

You must keep opts.size the same after you've written data. If you change the size, bad things will happen.

file.read(offset, length, cb)

Read length bytes at an offset from file as cb(err, buf).

file.write(offset, buf, cb)

Write buf to file at an offset.

install

npm install random-access-idb
