keyed-tus-store

Higher level tus store.

Takes a tus store and returns a new tus store which behaves mostly the except that it transforms upload IDs returned by create(key) so that the transformed upload ID also encodes the key argument.

Other functions are wrapped so that the original upload ID is decoded before being passed.

An additional decodeKey(uploadId) function is exposed which returns the key associated with an upload ID.

The idea behind this store was to make it easier to retrieve a key given an upload ID without requiring additional state.

Install

npm install --save keyed-tus-store

Requires Node v6+

Usage

See ./test directory for usage examples.

keyedStore(storeToWrap, secret)

Where storeToWrap is a tus store and secret is a secret passphrase used to encrypt and decrypt the upload IDs.

Returns a tus store.

decodeKey(uploadId)

Returns the key encoded in uploadId.

import keyedStore from 'keyed-tus-store'
import { memstore } from 'abstract-tus-store'

const store = keyedStore(memstore(), 'some secret')

store.create('some-key').then(({ uploadId }) => {
  const key = store.decodeKey(uploadId)
  key === 'some-key' // => true
})
