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 🙏

node-with-watch

带监控文件变更的 node cli

安装

npm i -g node-with-watch

or

yarn global add node-with-watch

通过命令行 cli 使用说明

node-with-watch some-path.js

等同于执行下面的命令后,当 some-path.js 变更时, 重新执行该命令

node some-path.js

通过 require 使用说明

// 方法一:模拟命令行调用

// 构造参数
process.argv[2] = 'some-path.js'
process.argv[3] = '--some-arg'

// 调用
const watcher = require('node-with-watch/cli')

// 方法二:模拟命令行参数

// 获取基础类
const { NodeWithWatcher } = require('node-with-watch')
const watcher = new NodeWithWatcher

// 调用
/**
 * @define runWithWatch
 * @param {string} path - 运行的文件路径
 * @param {array<string>} [argv] - 命令行参数
 */
watcher.runWithWatch('some-path.js', ['--some-arg'])

// 如果有额外的文件监控需求时,可以使用如下方法

// 添加文件状态监控
watcher.watch(path)

// 移除文件状态监控
watcher.unwatch(path)

// 是否文件在监控中
watcher.isWatched(path)

// 销毁所有监控和调用
watcher.destroy()

其他用法

const { watchFile } = require('node-with-watch')

/**
 * @define watchFile
 * @param {string} path
 * @param {number} [interval = 500]
 * @param {function} listener - ({string} type);  type in [create|change|remove]
 * @return {function} - unwatch
 */
watchFile('some-path.js', (type) => {
  // code
})
