Angular return value from one ts to another -

in angular project, have 2 ts files below:

data.ts

import { injectable } '@angular/core'; import { mystorage } '../storage';  @injectable() export class itemfromstorage { constructor(public storage: storage) {    }      getitemdatafromstorage(current){                 this.storage.get(current).then((val) => {           return val;  //????             });     };      } 

main.ts

import { itemfromstorage } '../data'  export class item_thumb {     constructor(public itemstorage: itemfromstorage) {       };       fetchthumbdata(){      var data = this.itemstorage.getitemdatafromstorage(this.datanumber);      console.log(data);//????    } } 

from data.ts, how return data value main.ts?

your data.ts method should return request itself, without subscribing it:

    getitemdatafromstorage(current){                 return this.storage.get(current);    };  

and in main.ts method subscribe , receive data:

   fetchthumbdata(){      var data = this.itemstorage.getitemdatafromstorage(this.datanumber).then((data) => {           console.log(data);//????          });      }
