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 🙏

ZenWeb Cache Module

基于 Redis 的对象缓存工具

功能如下:

  • 对象缓存
  • 大对象自动压缩
  • JSON 序列直接输出
  • 防止缓存击穿
  • 单例执行

安装

yarn add @zenweb/cache
import { create } from 'zenweb';
import modCache from '@zenweb/cache';

const app = create();

app.setup(modCache());

app.start();

使用

import { Context, mapping } from "zenweb";
import { $cache, cached } from "@zenweb/cache";

export class CacheController {
  /**
   * 一般使用
   */
  @mapping()
  async index() {
    const result = await $cache.lockGet('TEST', function() {
      return {
        cacheAt: new Date(),
      };
    });
    return result;
  }

  /**
   * 大对象压缩存储
   */
  @mapping()
  async big() {
    const result = await $cache.lockGet('TEST-GZ', function() {
      return longData;
    });
    return result;
  }

  /**
   * 大对象直接输出 - 1
   */
  @mapping()
  async big_direct_out(ctx: Context) {
    const result = await $cache.lockGet('TEST-GZ', function() {
      return longData;
    }, { parse: false, decompress: false });
    if (result.compressed) {
      ctx.set('Content-Encoding', 'gzip');
    }
    ctx.type = 'json';
    ctx.body = result.data;
  }

  /**
   * 使用缓存中间件
   * - 自动处理是否需要解压缩对象
   */
  @mapping({
    middleware: cached('TEST-middleware'),
  })
  async cached_middleware() {
    return longData;
  }
}
