SyntaxError: Unexpected token 'export' while exporting function Js-CodePudding

I'm trying to export a function from a Js file but recieving a Unexpected token error

const youtubeDownload = require("./youtube/youtube-download"); // export function youtubeDownload 
const twitterDonwload = require("./twitter/twitter-download"); // export function twitterDownload

function download(tweet) {
    if(tweet.in_reply_to_status_id_str == null) return youtubeDownload(tweet);
    if(tweet.in_reply_to_status_id_str != null) return twitterDonwload(tweet);
};

export { download };

This code is returning the error:

export { download };
^^^^^^

SyntaxError: Unexpected token 'export'

It's because you are using CommonJS modules by default in NodeJS. CommonJS modules doesn't support export syntax. So you may need to use CommonJS export syntax for this.

const youtubeDownload = require("./youtube/youtube-download"); // export function youtubeDownload 
const twitterDonwload = require("./twitter/twitter-download"); // export function twitterDownload

function download(tweet) {
    if(tweet.in_reply_to_status_id_str == null) return youtubeDownload(tweet);
    if(tweet.in_reply_to_status_id_str != null) return twitterDonwload(tweet);
};

module.exports = { download };

Or if you really wants to use export syntax, you can use ES6 modules as here: https://stackoverflow.com/a/45854500/13568664.

use module.exports={download} to export

use const {download}=require('<yourfilepath>') to import
