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 🙏

这是简化dva操作hook库,方便获取state和loading,dispatch操作

内容

注意: 总共导出两个方法和一个model对象,mergeModel,wrapperModel,model

1. mergeModel(model[])

  • 用于合并两到三个model。
  • 注意model内只能有一个namespace
  • 合并的model里state,reducer,effects,subscriptions等不能有相同的属性key值

2. wrapperModel(model)

  • 这个方法可以导出三个hook,分别是useModelState,useLoading,useCommit
  • 这几个hook分别简化获取state,loading, 和dispatch的操作
  • 对应操作可通过ts提示获取

demo

demo.ts

import { mergeModel,wrapperModel } from 'tin-dva-hook'
import testModel from './testModel

const demoModel = {
  namespace: 'namespace',
  state: {
    list: [],
    data: 1,
  },
  reducers: {
    save(state:any, action:any) {
      return { ...state, ...action.payload };
    }
  },
  effects: {
    *addTodo({ payload }, { call, put, select }) {
      yield put({ type: 'save',payload:{data:payload}});
    },
    *getData({ payload }, { call, put, select }) {
      // 模拟网络请求
      const data = yield call(todoService, payload.id);
      return data; // 返回promise
    },
  },
}
export const {
  model,
  useModelState,
  useLoading,
  useCommit
  } = wrapperModel(mergeModel(demoModel,testModel))
export default model
  调用方式
  import { useModelState, useLoading, useCommit } = from 'demo'

  function Demo(){
    const { list } = useModelState()
    const loading = useLoading('getData') // model异步请求effects的key值
    const commit = useCommit()

    // commit( 'getData',payload:xxx )
  }
