Package Exports

hyperid

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (hyperid) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

hyperid

Uber-fast unique id generation, for Node.js and the browser. Here are the benchmarks:

hashids process.hrtime x 27,255 ops/sec ±0.71% (91 runs sampled)
hashids counter x 55,038 ops/sec ±1.32% (88 runs sampled)
shortid x 33,322 ops/sec ±2.77% (75 runs sampled)
nid x 1,027,557 ops/sec ±1.08% (86 runs sampled)
uuid.v4 x 342,969 ops/sec ±1.37% (89 runs sampled)
uuid.v1 x 316,735 ops/sec ±3.56% (83 runs sampled)
hyperid x 9,131,590 ops/sec ±4.83% (73 runs sampled)

Install

npm i hyperid --save

Example

'use strict'

const hyperid = require('hyperid')
const instance = hyperid()

const id = hyperid()

console.log(id)
console.log(hyperid.decode(id))

API

hyperid()

Returns a function to generate unique ids.

instance()

Returns an unique id.

instance.uuid

The uuid used to generate the ids, it will change over time. It is regenerated every Math.pow(2, 31) - 1 to keep the integer a SMI (a V8 optimization).

hyperid.decode(id)

Decode the unique id into its two components, a uuid and a counter. It returns:

{
  uuid: '049b7020-c787-41bf-a1d2-a97612c11418',
  count: 1
}

This is aliased as instance.decode.
