Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Store files in KV backends with optional chunking.

Readme

kvfile

使用各种KV存储存储文件的JS库

共用逻辑

初始化

kvf = new KVFile({ cloud: "aliyun", kv, chunk: true, csize: 1024, bin: false }) cloud为提供商,kv为底层KV实例,chunk为是否启用分块,csize为分块大小(单位MB),bin为是否启用二进制,禁用时使用base64

分块

将文件分成多块,每块大小为csize,增加{文件名}_meta存储分块信息和大小

读取

kvf.read("文件名")

写入

kvf.write("文件名", 数据)

删除

kvf.delete("文件名")

阿里云

API

获取实例

const edgeKv = new EdgeKV({ namespace: "ns"});

获取值

get(key[, {type: “type”}])

写入/更新值

put(key,value)

删除KV对

delete(key)

示例

const { KVFile } = require("./index");

const edgeKv = new EdgeKV({ namespace: "ns" });
const kvf = new KVFile({
  cloud: "aliyun",
  kv: edgeKv,
  chunk: true,
  csize: 10,
  bin: false,
});

await kvf.write("hello.txt", "hello world");
const content = await kvf.read("hello.txt");
await kvf.delete("hello.txt");
