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 🙏

Readme

@sora-soft/redis-component

基于 node-redis 的 Redis 组件,封装了 Redis 客户端连接、JSON 序列化存储和分布式锁等功能,作为 sora 框架的基础设施组件使用。

安装

sora add:component @sora-soft/redis-component

功能说明

  • 封装 node-redis v4 客户端,提供统一的生命周期管理(loadOptionsstartstop
  • 提供 setJSON / getJSON 方法,自动进行 JSON 序列化与反序列化,支持 TTL 过期时间
  • 内置 Redlock 分布式锁支持,通过 createLock 创建锁实例
  • 支持用户名、密码、数据库选择等完整的 Redis 连接配置

使用方法

注册并启动组件

import { RedisComponent } from '@sora-soft/redis-component';
import { Runtime } from '@sora-soft/framework';

const redis = new RedisComponent();
Runtime.registerComponent('redis', redis);
redis.loadOptions({
  url: 'redis://127.0.0.1:6379',
  database: 0,
});
await redis.start();

基础操作

const client = redis.client;
await client.set('key', 'value');
const value = await client.get('key');

JSON 存储

interface User { name: string; age: number; }

await redis.setJSON<User>('user:123', { name: 'Alice', age: 30 }, 60000);
const user = await redis.getJSON<User>('user:123');

分布式锁

const lock = redis.createLock({ retryCount: 3, retryDelay: 200 });

await lock.using(['my-resource'], 5000, async () => {
  // 临界区操作,最多持有 5 秒
});
