Build Status codecov

Kaciras 博客的 Node 本地扩展,包含了一些需要在底层实现的功能。

xxHash

xxHash 是一个非加密 Hash 函数系列,拥有很快的运算速度。本项包含 xxHash3_128 算法的 Node 扩展。

安装

npm i @kaciras-blog/nativelib

默认情况将从 GitHub Release 上下载编译好的二进制文件,如果需要自己编译请添加--no-prebuild参数。

用法

xxHash

使用跟 crypto 模块相似的 API:

const { createXXH3_128 } = require("@kaciras-blog/nativelib");

console.log(createXXH3_128().update("xxhash").digest("hex"));
// 9c8b437c78cac00a376072e24bfdf4d2

使用快捷函数:

const { xxHash3_128 } = require("@kaciras-blog/nativelib");

console.log(xxHash3_128("xxhash", "base64url")); // nItDfHjKwAo3YHLiS_300g

xxHash 算法非常快,故没有提供异步的版本。

hashSum

计算一个对象的 Hash,底层使用 xxHash3_128 算法,返回 16 字节的 buffer 对象。该函数可以作为 hash-sum 的替代。

const { hashSum } = require("@kaciras-blog/nativelib");

const hash = hashSum({
	a: 12345,
	b: null,
	c: ["foo", "bar"],
	d: { foo: true },
});

console.log(hash.toString("base64url")); // n2mK3P2WyGed560H01IaTA
