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 🙏

mobx-custom

  • mobx的observabe和extendObservable, 都不会对自定义类的实例进行处理
  • 提供deepExtendObservable, 让mobx支持自定义类

mobx-custom例:

yarn add mobx mobx-custom
import {deepExtendObservable} from "mobx-custom"
import {observe} from "mobx"

class Address = {
  city = "上海"
  cityCode = -1
  desc = "xx路"
}

class Person {
  age = 10
  address = new Address()
}

const oriPerson = new Person()
const person = deepExtendObservable(oriPerson, {...oriPerson})
observe(person, () => {
  console.log('person属性有变动')
})
person.address = new Address() // 触发observe
person.address.city = "北京" // 触发observe
person.age = 200 // 触发observe

mobx例:

import {deepExtendObservable} from "mobx-custom"
import {observe, observable, extendObservable} from "mobx"

class Address = {
  city = "上海"
  cityCode = -1
  desc = "xx路"
}

class Person {
  age = 10
  address = new Address()
}

// mobx会将普通对象进行observable
const obj = observable({a: 1})
observe(obj, () => {
  console.log('obj属性有变动')
})
person.a = 2 // 触发observe

// mobx不会对person1做处理
const person1 = observable(new Person())
observe(person1, () => {
  console.log('person1属性有变动')
})
person.age = 2 // 不会触发observe

// mobx不会对person2.address做处理
let oriPerson2 = new Person()
const person2 = extendObservable(oriPerson2, {...oriPerson2})
observe(person2, () => {
  console.log('person2属性有变动')
})
person.age = 2 // 会触发observe
person.address = new Address() // 不会触发observe
