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 🙏

redux like dva

Readme

use redux like dva

引入方式

npm i redux-dva --save 或者
yarn add redux-dva -D

自己项目需要支持
react redux react-redux

配置方式 app主入口

import store from 'redux-dva'
import {Provider} from 'react-redux'

import model from '自己的model配置如下'

const storeIns = store.init([model])

export default () => {
  
  return (
    <Provider store={storeIns}>
      route配置
    </Provider>
  )
}

model配置,和dva差不多

export default {
  namespace: 'test',
  state: {
    data: '1234'
  },
  effects: {
    async getData(payload,{select,put}){
      // select获取当前model的state,put调用当前model的effect和reducer
      const curretModelState = select()
      put({
        type: 'update',
        payload: ''
      })
      
      const allState = this.getState() // 获取store所有的state
      const {test} = allState
      console.log(test)
      // this.disaptch可以调用其他model的effect和reducer
      // 所有dispatch方法都会调用effect和reducer,所以最好不要重名,不然先effect,reducer不会调用
      this.dispatch({
        type: 'othernamespace/update',
        payload: {
          data: 'change'
        }
      })
    }
  },
  reducer: {
    update(payload,state){
      // payload传入参数,state是本model的state的值
      return {
        ...state,
        ...payload
      }
    }
  }
}

组件使用

import React,{useEffect} from "react";
import {connect} from 'redux-dva'

const Com = (props) => {
    const {data,dispatch} = props
    useEffect(() => {
        // connect后的dispatch支持如下写法	
       // dispatch.test.getList({data:123}) 和下同效果
        dispatch({
          type: 'test/getList',
          payload: {
            data:'123'
          }
        })
    },[])
    return (
        <div>
            hello world
            {data}
        </div>
    )
}

export default connect(
  state => ({
    ...state.test
  })
)(Com)

// 也支持hooks写法  函数组件中
import {useDispatch,useModel} from 'redux-dva'

export default () => {
  const dispath = useDispatch()
  const data = useModel()  // 获取的是所有model的state
  const {test} = data
  return (
    <div>
      {test.xxx}
      hello world
    </div>
  )
}
