PWorkbook - Typescript reducer (like vuex)

state management pattern + library.

• Download one short typescript file.

https://github.com/shemeshg/PWorkbook/blob/master/src/components/PWorkbook.ts

Project setup

• Create store file and import PWorkbook.ts

https://github.com/shemeshg/PWorkbook/blob/master/src/components/Store.ts

import {PWorkbook} from "./PWorkbook"

function initWbk(){
  const pw = new PWorkbook()
  const shalom  = pw.addRef("shalom")
  // array is all dependent fields
  const textComputed = pw.addComputed( ()=> {return shalom.ref +  "dummy text" } , [shalom])

  return  {pw, shalom, textComputed}
}

export const params = initWbk();

• Import store to component

import {params} from "./Store"

@Component
export default class Component1 extends Vue {
  shalom = params.shalom.ref  
  textComputed = params.textComputed.ref
  symbl = Symbol()

  mounted() {
    params.pw.setRefreshCallback(this.symbl, (ret) => {      
      ret.t(params.shalom, ()=>{{ this.shalom = params.shalom.ref}})
      ret.t(params.textComputed, ()=>{{ this.textComputed = params.textComputed.ref}})
      return;
    })
  }

  destroyed(){
    params.pw.unSetRefreshCallback(this.symbl)
  }

  whenClicked(){
    params.shalom.ref = "text2"
  }

}

Use getter and setter on typescript components

  pShalom = params.shalom.ref  
  get shalom(){ return this.pShalom}
  set shalom(s){params.shalom.ref = s}

  mounted() {
    params.pw.setRefreshCallback(this.symbl, (ret) => {      
      ret.t(params.shalom, ()=>{{ this.pShalom = params.shalom.ref}})
    })
  }  

Or in Vue Composition API with simple helper file (CompositHelper.ts)

See (also for lists and dictionaries): https://github.com/shemeshg/PWorkbook/blob/master/src/components/HellowWorldComposition.vue

  setup () {
    const ch = new CompositHelper(params.pw)
    
    onMounted(()=>{
      ch.onMounted()
    })

    onUnmounted( ()=>{
      ch.onUnmounted()
    })
    
    return {shalom: ch.getRef(params.shalom) };
  },

Compiles and hot-reloads for development

npm run serve
