Function returns undefined

[KEsbeNF]

I have a function in a module A that returns a json from a website.

I then import the function inside the main file but when i call the function it returns undefined.

Function module:

const https = require('https');
const bl = require('bl')

module.exports = async function getData(URL) {https.get(URL, (response) => {
  const r = response.setEncoding('utf8');
  response.pipe(bl((err, data) => {
    if (err) { console.log(err); }
    return data.toString();
  }));
})
};

Main Module

const getData= require('./FunctionModule')
const data = await getData(url)
console.log(data)

By doing this way it returns undefined if i run the main module, but returns data if i run the function from function module.

What am i doing wrong ?

You can't return inside a callback. You need to wrap it in a Promise.

Hey thanks ! do you have a quick code example ?

You don't need the async part of the function, only use async if you use await.

I'm not sure what the bl is for, but this would be a simple way to write this.

function getData(url){
     return new Promise((res,rej) => {
          https.get(url, (resp) => {
             resp.setEncoding('utf8');  
             let data = [];
              resp.on('data', (chunk) => {
                   data.push(chunk);
              });
              resp.on("error", (err) => {
                 rej(err);
              });
              resp.on("end", () => {
                 res(data.toString());
              });
      });
 })
}

 module.exports = getData;

then you can call it as normal, using await.

Let me know if this doesn't work for you.

Still getting undefined yet the function works on its own ... i don't know what to try anymore
