SyntaxError: Unexpected token 'export' while exporting function Js [duplicate]

Question

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'

Answer 1

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.
