How to do GET request synchronously in node.js (http/https)

https-get-promisify.js

const https = require("https")

const httpsGetSync = (url) => {
    return new Promise((resolve, reject) => {
        let req = https.get(url, (res)=>{
            
            var retData = "";
            res.on("data", (chunk)=>{
                // do your work here.
                retData += chunk;
            });
            
            res.on("end", ()=>{
                // resolve(return) data here.
                resolve(retData);
            });
        });
        
        req.on("error", (err)=>{
            // throw err
            reject(err);
        });
        req.end();
    });
};

// example
var exampleFunc = async () => {
    try{
        var res = await httpsGetSync("www.example.com");
        
        // do work with result
        console.log(res);
    } catch(err){
        // catch error while request
        console.error(err);
    }
};

// or
var exampleFunc2 = () => {
    httpsGetSync("www.example.com")
    .then((res)=> {
        // do work with result
        console.log(res);
    })
    .catch((err)=>{
        // catch error while request
        console.err(err);
    });
};
