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

rein-schedule

Install

npm i @reinjs/rein-schedule

Usage

在项目文件夹或者插件文件夹中会存在一个文件夹 schedule,下面所有的文件都将被认为是一个任务,任务必须存在2个属性或方法:

  • rule object或者string 时间规则 参考 https://www.npmjs.com/package/node-schedule#cron-style-scheduling
  • task function 执行逻辑

比如我们创建一个任务 app/schedule/test/db.js:

const Schedule = require('@reinjs/rein-schedule');

module.exports = class DbSchedule extends Schedule {
  constructor(...args) {
    super(...args);
  }

  /**
   * 此属性可以直接用字符串表示
   * 比如 `return '0 17 ? * 0,4-6'`
   */
  rule() {
    const rule = new Schedule.RecurrenceRule();
    rule.dayOfWeek = [0, new Schedule.Range(4, 6)];
    rule.hour = 17;
    rule.minute = 0;
    return rule;
  }

  async task() {
    // this.app do something.
  }
}
  • 获取方式 app.schedule.test.db,遵守reinjs约定都规范。
  • 取消任务 await app.schedule.test.db.cancel()

注意 此插件只允许使用在agent进程上
