hamt-sharding
JavaScript implementation of sharding using hash array mapped tries
About
A Hash Mapped Trie implementation for JavaScript.
This is used by @helia/unixfs for it's HAMT-sharded directory implementation.
Example
import { createHAMT } from 'hamt-sharding'
import crypto from 'crypto-promise'
// decide how to hash buffers made from keys, can return a Promise
const hashFn = async (buf) => {
return crypto
.createHash('sha256')
.update(buf)
.digest()
}
const bucket = createHAMT({
hashFn: hashFn
})
await bucket.put('key', 'value')
const output = await bucket.get('key')
// output === 'value'Install
$ npm i hamt-shardingBrowser <script> tag
