How can i use promise returned data in another function later on

Question

async function getOrderdata(orderId) {
  //await the response of the fetch call
  let response = await fetch('http://localhost:3245/api/Orders/' + orderId);

  //proceed once the first promise is resolved.
  let data = await response.json();

  //proceed only when the second promise is resolved
  return data;
}

I have the shown code and i want to use getOrderdata function in another js file?

Answer 1

Put the function in a module.exports object and use an async-await function in the importing file.

// file exporting the function - exp.js
     module.exports = {
             getOrderdata : async function(orderId){
             //await the response of the fetch call
             let response = await fetch('http://localhost:3245/api/Orders/' + orderId);

             //proceed once the first promise is resolved.
             let data = await response.json();

             //proceed only when the second promise is resolved
             return data;
             }



// file importing the async function - imp.js
const { getOrderdata } = require("./exp.js")
;(async () =>{
    let msg = await getOrderdata()
    console.log(msg)
})();
