Outra maneira de fazer isso na função assíncrona:
const express = require('express')
const path = require('path')
const db = require(path.join(__dirname, '../database/config')).db;
const router = express.Router()
// Create.R.U.D
router.post('/new-order', async function (req, res, next) {
// security check
if (Object.keys(req.body).length === 0) {
res.status(404).send({
msg: "Error",
code: 404
});
return;
}
try {
// operations
let orderNumber = await db.collection('orders').countDocuments()
let number = orderNumber + 1
let order = {
number: number,
customer: req.body.customer,
products: req.body.products,
totalProducts: req.body.totalProducts,
totalCost: req.body.totalCost,
type: req.body.type,
time: req.body.time,
date: req.body.date,
timeStamp: Date.now(),
}
if (req.body.direction) {
order.direction = req.body.direction
}
if (req.body.specialRequests) {
order.specialRequests = req.body.specialRequests
}
// Here newOrder will store some informations in result of this process.
// You can find the inserted id and some informations there too.
let newOrder = await db.collection('orders').insertOne({...order})
if (newOrder) {
// MARK: Server response
res.status(201).send({
msg: `Order N°${number} created : id[${newOrder.insertedId}]`,
code: 201
});
} else {
// MARK: Server response
res.status(404).send({
msg: `Order N°${number} not created`,
code: 404
});
}
} catch (e) {
print(e)
return
}
})
// C.Read.U.D
// C.R.Update.D
// C.R.U.Delete
module.exports = router;
