What is different between module.exports = testMethod;
and module.exports = { testMethod };
Because when I am using module.exports = testMethod;
it is throwing error as below. Error: Route.get() requires a callback function but got a [object Undefined] But I am okay with module.exports = { testMethod };
Whole codes are
const testMethod = asyncErrorWrapper(async (req, res, next) => {
const information = req.body;
const question = await Question.create({
title: information.title,
content: information.content,
user: req.user.id,
});
res.status(200).json({
success: true,
data: question,
});
});
module.exports = { testMethod };
From VSCode, change between the ES5 or ES6 version to Js can take you on a bad way. So, be carreful, i have the same problem recently, and after refactoring by use on ES6 module.exports = router
to the end of some Js file (Node project using express) it was done.
Strange for me, on Cloud9 on Aws i have no problems.
Both are worked to export your module to outside function. But when you are using any callback function with
module.exports = somectrl
then it will fail but
module.exports = { somectrl }
because when you create an object, it actually instanciate it but when you pass a ref function/ const function name then it will behave as a existing function which does not work right.
you can do something like this to work,
module.exports = somectrl()
or
module.exports = new somectrl()
