I want to run my function as I wrote it, but as we know node.js is asynchronous language, so the code in the run in an async manner here my problem starts in my code I want to execute each line of code in the sequence of as they write.
Now my question is that how to run a function sequentially in Node.js.
Here is my code of index.js file where i calling function
var request = require('request');
var requestHandling = require('../routes/request_handling_functions');
router.get("/example1", function (req, res) {
var result =
requestHandling.requestMethodGet('http://localhost:8083/getUserInfo/865c2c25-d9e7-412d-a064-326bd66c9e9c', res);
console.log("===RESULT=====");
console.log(result);
});
in above code I want to call the requestMethodGet function first, and after that, I want to console the result of that function. but whole things went wrong it executes the console.log lines first then it calls the function.
My output in the console is
===RESULT=====
undefined
Here is my file in which i define that function
var request = require('request'); var log = require('log4js').getLogger("index");
module.exports = {
requestMethodGet: async function (url, res) {
//SET ALL THESE PARATMETER TO MAKE REQUEST
request.get({url: url}, function (e, r, body) {
var errorResult = module.exports.validateResponseeData(e);
console.log("====errorResult===in===Get==method====");
console.log(errorResult);
if (errorResult != "continue") {
console.log("===im in not continue");
res.send(errorResult);
} else {
//LOGING THE RESPONSE BODY
log.info('body:', body);
var responseData = JSON.parse(body);
console.log("======AUTHTOKEN=========DATA=====================");
console.log('error:', e);
console.log('statusCode:', r && r.statusCode);
console.log('body:', body);
console.log("====================================");
console.log(responseData);
res.send(responseData);
}
});
}
if any help is needed regarding this question or wants more information, then please inform me.
