Call a function from another file doesn't work on my JS file. I can't call a function from another js file.I think the problem is between connecting two files.
my first JS file
const { response } = require('express');
var express = require('express');
const {render}=require('../app');
const productHelpers = require('../helpers/product-helpers');
var router = express.Router();
var productHelper=require('../helpers/product-helpers')
/* GET users listing. */
router.get('/', function(req, res, next) {
productHelpers.getAllProduct().then((products)=>{
res.render('admin/veiw-products', { admin: true, products })
})
});
router.get('/add-product', function (req, res) {
res.render('admin/add-product')
})
router.post('/add-product', (req, res) => {
console.log(req.body)
console.log(req.files.image)
productHelpers.addProduct(req.body, (id) => {
console.log(id)
let image = req.files.image
image.mv('./public/product-images/' + id + '.jpg', (err, done) => {
if (!err) {
res.render('admin/add-product')
}else{
console.log(err);
}
})
})
})
router.get('/delete-product/:id',(req,res)=>{
let proId=req.params.id
console.log(proId);
productHelpers.deleteProduct(proId).then((response)=>{
res.redirect('/admin/')
})
})
module.exports = router;
my second JS file
var db = require('../config/connection')
var collection = require('../config/collections');
const {Delete} = require('../routes/admin');
module.exports = {
addProduct: (product, callback) => {
console.log(product);
db.get().collection('product').insertOne(product).then((data) => {
callback(data.ops[0]._id)
})
},
getAllProduct:()=>{
return new Promise(async(resolve,reject)=>{
let products=await db.get().collection(collection.PRODUCT_COLLECTION).find().toArray()
resolve(products)
})
},
deleteProduct:(prodId)=>{
return new Promise((resolve,reject)=>{
db.get().collection(collection.PRODUCT_COLLECTION).removeOne({_id:prodId}).then((response)=>{
console.log(response)
resolve(response)
})
})
}
}
my error report
productHelpers.getAllProduct is not a function
