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

dva-atr

对于dva的model进行了扩展

使用

使用前一定要看

$ npm install dva-atr
$ yarn add dva-atr
import { modelCtr, actionCtrCenter } from 'dva-atr'

创建model


import { modelCtr } from 'dva-atr'
import { Map } from 'immutable'

export default modelCtr(({ actionCtr, actionCtrCenter }) => ({

  namespace: 'example',

  state: {},

  effects: {
     * fetch(__, { call, put, select }) {
        const json = yield call(requestMgr.fetch, ...)
        if (json) {
            /**
             * 请在修改model过程当初,保证state的类型始终是你期望的
             */
            yield put(actionCtr.set({
                path: '/',
                value: Map(json)
            }))
        }
    }
  },

  subscriptions: {
    listen({ dispatch, history }) {
      dispatch(actionCtr.set({
        path: 'type',
        value: 'change'
      }))
    }
  }

}))

listen

  • listen可以接受一个函数或者数组(默认监听当前namesapce为路由的路径)

  • listen还可以接受一个对象,key值为监听的路由

  • 注意:监听路由都不需要在前面加上/

 `if (pathname === `/${namespace}`) `

管理组件中使用

actionCtr/reducers

|名称|说明| |-- |-- | |set|设置path路径下的value为新值| |setMulti|一次性设置多次,只触发一次渲染| |reset|重置path路径下的model为初始化值(modelCtr创建时候,返回的state)| |resetMulti|一次性重置多次,只触发一次渲染| |update|更新path路径下的model,deal字段为函数oldModel => newModel|


import { actionCtrCenter } from 'dva-atr'

const mapDispatchToProps = dispatch => ({
  onBtnClick() {
    dispatch(actionCtrCenter['example'].set({
        path: 'type',
        value: 'change-click'
    }))
    dispatch(actionCtrCenter['example'].update({
        path: 'Index.modal.visible',
        deal: val => !val
    }))
  },
  onLogoutBtnClick() {
    _.forEach(actionCtrCenter, actionCtr => {
        dispatch(actionCtr.reset({
            path: '/'
        }))
    })
  }
})

const mapStateToProps = ({
   example
}) => {
   /**
    * 注意model的类型为immutable,请根据你的需求进行关联
    */  
  return example.toJS()
}
