Node.js syntax error "unexpected token" on "exports."

Question

I have been trying to learn node.js. I am trying to create a simple node.js web api and a html-javascript front end to login using Facebook auth and store Facebook id in Mongodb.

I was able to do it by following tutorials available online.

Now I want to segregate the code into multiple files but when I try to create a route "user" and expose functions via exports. I am getting the following error.

module.exports.userLogin = function(req,res){
      ^ SyntaxError: Unexpected token .
    at Module._compile (module.js:437:25)
    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Module.require (module.js:362:17)
    at require (module.js:378:17)
    at Object.<anonymous> (C:\Users\Saumya\Desktop\vhsharedraft\web.js:2:6)
    at Module._compile (module.js:449:26)
    at Object.Module._extensions..js (module.js:467:10)
    at Module.load (module.js:356:32)

EDIT#1

module.exports.userLogin = function(req,res){
    graph.setAccessToken(req.session.fb.access_token);

    graph.get("/me", function(err, data) {
        if(err){
            console.log('Error obtaining data.');
            return;
        }
        console.log(data);
    }

}

EDIT # 2

var mongo = require('mongodb'),
graph = require('fbgraph');



exports.userLogin = function(req,res){
    graph.setAccessToken(req.session.fb.access_token);

    graph.get("/me", function(err, data) {
        if(err){
            console.log('Error obtaining data.');
            return;
        }
        console.log(data);
    }
}

This is all I have in user route. Actually, I was making a real silly mistake, I left a comma in front of graph = require('fbgraph') instead of semi colon. After fixing this syntax error, I am getting this error.

Usually you just need to do exports.funcName = function() { }, so I'd start there. If I could see the rest of the code around where it's failing I could probably be more helpful. – Purdy

If you are referring to "module.exports" instead of "exports". I have tried the latter too with same error. – Vouge

This could be a really silly mistake as I am a newbie. Do we need to "require" something to use "exports"? – Vouge

again, use exports.userLogin = instead of module.exports.userLogin. Secondly is there any other code in the file? 3rd, how are you getting that error, what command are you using? – Purdy

Answer 1

You have a typo here:

graph.get("/me", function(err, data) {
    if(err){
        console.log('Error obtaining data.');
        return;
    }
    console.log(data);
}

It should be:

graph.get("/me", function(err, data) {
    if(err){
        console.log('Error obtaining data.');
        return;
    }
    console.log(data);
}); /* Note the added parenthesis here */

Also use exports.userLogin instead of module.exports.userLogin

Could you explicitly show the different part? Or make it bold? it's very hard to read through linek seeking for the part which is different in two examples – Jillianjillie
