Currently I'm doing this:
filename : userOrder.js
const paymentGateway = require('./paymentGateway');
module.exports = {
save: function() {
// save user order record
return paymentGateway.makePayment();
},
update: function() {
// update user order record
}
}
filename: paymentGateway.js
const payment = require('./payment');
module.exports = {
makePayment: function() {
// make payment
return payment.save();
}
}
filename : payment.js
const userOrder = require('./userOrder');
module.exports = {
save: function() {
// save payment record
return userOrder.update();
}
}
return userOrder.update(); -> this line gives an error "TypeError: userOrder.update is not a function"
This is because you are using circular references between payment.js and userOrder.js. You can fix this by assigning a value to module.exports before you call require, like this:
userOrder.js
const userOrder = function() { };
module.exports = userOrder;
const paymentGateway = require('./paymentGateway');
userOrder.save = function() {
// save user order record
return paymentGateway.makePayment();
}
userOrder.update = function() {
// update user order record
}
payment.js
const payment = function() {};
module.exports = payment;
const userOrder = require('./userOrder');
payment.save = function() {
// save payment record
return userOrder.update();
}
No changes are required to paymentGateway.js, as this isn't part of a circular require.
