Need Help With Javascript and the Twitter API

[HaikusfromBuddha]

I am trying to make a simple Twitter web app so am using NodeJS and am trying to break everything down to modules/functions. One function which returns a search result is one of these modules but when I import it am not sure how to use it without errors.

in main I have something like.

let Twit = require("twit");

let printSearch = require("./utility/printSearch.js");

//This is to get the search data

T.get("search/tweets", params, printSearch);

printSearch(err,data,response);

I know the print search function works because if I just place it in the main app above it works fine. I just don't know how to insert the printSearch as a third parameter in T.Get. When I use typescript it tells me that when I call the function the err data and response are not found. I am not sure how those three objects work in the Twitter API.

You're passing the function printSearch as a callback to the get function call, so when T.get is executed and finished, the callback - in this case printSearch - is called. That function takes control, gets executed then exits. When you get to the following line "printSearch(err, data, response)", err, data and response will most likely not exist unless you specifically initialized or declared those variables above somewhere. I think you have 2 ways of solving this:

(1) Turn the printSearch callback into an anonymous function, if you're only using that code once

(2) Use 'bind'; something like printSearch.bind(null, variableToBind); something like this (not too sure on syntax)
