mountable-dwebtrie

A DWebTrie wrapper that supports mounting of sub-DWebTries.

Usage

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

const store = basestore(ram)
const trie1 = new MountableDWebTrie(store)
const trie2 = new MountableDWebTrie(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-dwebtrie re-exposes the dwebtrie API, with the addition of the following methods (and a different constructor):

const trie = new MountableDWebTrie(basestore, key, opts)

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

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

• path is the mountpoint
• key is the key for the MountableDWebTrie 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 dwebtrie methods. Here's what's been implemented so far:

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