TypeError: object.function is not a function

Question

I have 2 files QueryExecution.js and app.js; from app.js am calling a function query_result which is in QueryExecution.js. But when I made the call in app.js am getting object.function is not a function.

Kindly apologize for any stupid mistakes :( Thanks in advance for your time and help

I tried to print the object(realtime_chart_new) that I created to call the function. the object is printing the entire function content.

QueryExecution.js

function query_result(connection,sql) {
    .......query statements and processing content .....
        return CountOrders, TotalAmt;
}
module.exports = query_result;

app.js

var connection = {
    .....connection statements .....
};

var realtime_chart_new = require('./QueryExecution.js');
var SalesCountOrders, SalesTotalAmt = realtime_chart_new.query_result(connection,sql);```



#Below is the error statements:

var SalesCountOrders, SalesTotalAmt = realtime_chart_new.query_result(connection,sql);
TypeError: realtime_chart_new.query_result is not a function

Does realtime_chart_new contain query_result, or is it printing the entire function directly? Also, what is exported from the file 'QueryExecution.js' ? — Caramiriel

realtime_chart_new directly prints the entire code that I wrote inside query_result — Santhosh Kumar

That would probably mean realtime_chart_new is default export and you would need to call it directly like realtime_chart_new() — 1565986223

That's great !!!! it worked !!! But I didn't understand how it worked with just object name and without function name. Pls, post this as the answer. I'll mark it as accepted. Thank you so much :) — Santhosh Kumar

To add answer, edit your question to reflect the way you've exported in your QueryExecution.js — 1565986223

You have overridden module exports with query_result, so now require('./QueryExecution.js') returns a function.

This will give you expected result:

module.exports.query_result = query_result;

OR

module.exports = {
    query_result: query_result
};
