I am trying to create a nodejs API separated by controllers and routes. I am trying to findandupdate in multiple collections and then put them in multiple promises to return a single response but i get just a null
what am i doing wrong below ?
controller.js
var x = (req, res, next, userID, product) => {
let query = {
uid: userID
}
let update = {
$push: {
product: product,
}
}
let options = {
safe: true,
new: true,
upsert: true
}
Model.findOneAndUpdate(query, update, options).exec()
.then(result => {
return true
})
.catch(err => {
console.log(err);
res.status(500).json({ error: err });
})
};
module.exports = x;
Route.js
const controller = require('./user-product')
router.post('/api', function (req, res, next) {
var p1 = controller(req, res, next, userID, product)
var allDone = Promise.all([p1])
allDone
.then(function (e) {
res.send(e) //this is null
})
.catch(function (e) {
console.log(e);
})
});

You are not returning promise from the controller function. You are just returning the result
and the error
So, Instead you should return the promise inside the controller function
Route.js
const controller = require('./user-product')
router.post('/api', function (req, res, next) {
var p1 = controller(req, res, next, userID, product)
var allDone = Promise.all([p1])
allDone.then(function (e) {
res.send(e)
})
.catch(function (e) {
console.log(e);
})
})
controller.js
var x = (req, res, next, userID, product) => {
let query = { uid: userID }
let update = { $push: { product: product }}
let options = {
safe: true,
new: true,
upsert: true
}
return Model.findOneAndUpdate(query, update, options).exec()
}
module.exports = x;
And probably easier with the async await syntax
Route.js
const controller = require('./user-product')
router.post('/api', async(req, res, next) => {
try {
const p1 = await controller(req, res, next, userID, product)
console.log(p1)
} catch (err) {
console.log(err)
}
})
controller.js
var x = async(req, res, next, userID, product) => {
let query = { uid: userID }
let update = { $push: { product: product }}
let options = {
safe: true,
new: true,
upsert: true
}
return Model.findOneAndUpdate(query, update, options).exec()
}
module.exports = x;
