mountable-dwtrie v2.0.0

mountable-dwtrie

A Hypertrie wrapper that supports mounting of sub-Hypertries.

Usage

A MountableHypertrie can be mounted within another MountableHypertrie by using the mount command:

const store = dwebx(ram)
const trie1 = new MountableHypertrie(store)
const trie2 = new MountableHypertrie(store)

trie2.ready(() => {
  trie1.mount('/a', trie2.key, ...)
})

Assuming trie2 has a value 'hello' at /b/c:

trie1.get('/a/b/c', console.log) // Will return Buffer.from('hello')

A mount can be removed by performing a del on the mountpoint :

trie1.del('/a', err => {
  trie1.get('/a/b/c', console.log) // Will print `null`
})

API

mountable-dwtrie re-exposes the dwtrie API, with the addition of the following methods (and a different constructor):

const trie = new MountableHypertrie(dwebx, key, opts)

• dwebx: any object that implements the dwebx interface. For now, it's recommanded to use random-access-dwebx
• key is the dwtrie key
• opts can contain any dwtrie options

trie.mount(path, key, opts, cb)

• path is the mountpoint
• key is the key for the MountableHypertrie to be mounted at path

opts can include:

{
  remotePath: '/remote/path', // An optional base path within the mount.
  version: 1                  // An optional checkout version
}

Note: We're still adding support for many dwtrie methods. Here's what's been implemented so far:

• get
• put
• del
• batch
• iterator
• list
• createReadStream
• createWriteStream
• checkout
• watch
• createHistoryStream
• createDiffStream
