Question

Here’s a simplified code example for what I’m doing.

foo.js (in lib directory):

exports.foo = function foo() {
    this.bar = function() {
        console.log("foobar!");
    };
};

main.js:

var foo = require("foo");
exports.main = function(options, callbacks) {
    foo.bar();
}

cmd:

>cfx run
[...]
error: An exception occurred.
[...]
TypeError: foo.bar is not a function

So basically, I can’t seem to do anything with the module I’ve imported. Am I doing something wrong here? I’ve tried formatting the foo() function in a few different ways and none of them seem to be able to do anything.

Thanks!

Answer 1

The result of the require() function is essentially the exports variable of the module – and you didn’t define exports.bar. So either you call foo.foo.bar() in your main.js or you import the module slightly differently:

var {foo} = require("foo");

This is the same as:

var foo = require("foo").foo;

Also, as erikvold notes in his answer, you didn’t really define exports.foo.bar.
