hyperid-wasm
以 ZZ 编写并编译为 WebAssembly (WASM) 格式的 HyperID 实现
Installation
Node
$ npm install @12core/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])
创建一个新的 hyperid 生成器，其中 opts 是相同的参数 赋予原始 hyperid。
const generator = hyperid({
fixedLength: false, // use a fixed length counter
startFrom: 0, // initial counter value
urlSafe: false, // use URL safe characters
})
id = generator()
从 hyperid 上下文生成一个 hyperid。 （见上文）
const id = generator()
Benchmark
这个原始模块比这个快 4 倍 .
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
默认情况下，该模块为 WebAssembly 模块分配 2 页内存。 即 2 * 64 * 1024 字节。
Maximum Memory
该模块最多允许 256 页内存。 即 256 * 64 * 1024 字节。

hyperid-wasm
A HyperID implementation written in ZZ compiled to WebAssembly (WASM) format
Installation
Node
$ npm install @12core/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.
