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 🙏

定时任务计划

快速安装

npm install fastcar-timer

使用场景

用于定时任务或者cron表达式的任务计划执行

使用示例

  • 基于时间间隔的调用
import { EnableScheduling, ScheduledInterval } from "fastcar-timer";

//开启调度计划
@EnableScheduling
class TimerTest {
   hello: string;

   constructor() {
    this.hello = "aaa";
   }

   //默认时间单位为ms 可使用其他计量单位也行
   //本注解的意思为 初始化执行延迟 1ms 每隔1s中执行一次
   @ScheduledInterval({ fixedRate: 1000, initialDelay: 1 })
   run() {
    console.log(this.hello);
   }
}

  new TimerTest(); //实例化后触发条件
  • 基于cron的调用
import { EnableScheduling, ScheduledCron } from "fastcar-timer";

//开启调度计划
@EnableScheduling
class TimerTest {
   hello: string;

   constructor() {
    this.hello = "bbb";
   }

   //含义为每隔1s执行一次
   @ScheduledCron({ cron: "*/1 * * * * *" })
   run() {
    console.log(this.hello);
   }
}

new TimerTest();
  • ScheduledCron 与 ScheduledInterval区别, 前者精度最小为1S 后者精度最小为5ms(具体看nodejs限制)

  • cron的实现方式是引用croner加以实现(之前版本cron存在内存泄漏问题)

注解说明

EnableScheduling 作用于类上 用于表示开启定时任务执行计划

ScheduledInterval 作用于具体方法上 任务按照固定间隔执行

ScheduledCron 作用于具体方法上 任务按照cron表达式执行
