hyperid-wasm

A HyperID implementation written in ZZ compiled to WebAssembly (WASM) format

Installation

Node

$ npm install @little-core-labs/hyperid-wasm

WAPM

$ wapm install jwerle/hyperid-wasm

Usage

const hyperid = require('hyperid-wasm')

hyperid.ready(() => {
  const hid = hyperid({ fixedLength: true, startFrom: 1024 })
  console.log(hid()) // atd1gpRDT1SJZnaOhdLR5Q/0000001024
  console.log(hid()) // atd1gpRDT1SJZnaOhdLR5Q/0000001025
})

API

generator = hyperid([opts])

Create a new hyperid generator where opts is the same arguments given to the original hyperid.

const generator = hyperid({
  fixedLength: false, // use a fixed length counter
  startFrom: 0, // initial counter value
  urlSafe: false, // use URL safe characters
})

id = generator()

Generate a hyperid from hyperid context. (See above)

const id = generator()

Benchmark

This original module is ~4x faster than this one.

hyperid generate - variable length (original) x 11,806,789 ops/sec ±1.59% (83 runs sampled)
hyperid generate - variable length (wasm) x 4,179,909 ops/sec ±0.95% (88 runs sampled)
hyperid generate - fixed length (original) x 9,347,663 ops/sec ±3.26% (88 runs sampled)
hyperid generate - fixed length (wasm) x 3,772,629 ops/sec ±2.14% (92 runs sampled)

Limits

Initial Memory

By default, this module allocates 2 pages of memory for the WebAssembly module. That is 2 * 64 * 1024 bytes.

Maximum Memory

This module allows at most 256 pages of memory. That is 256 * 64 * 1024 bytes.
