nodemon_app 崩溃 - 在开始之前等待文件更改

Question

1.This is my productController:

const Product = require('../models/product')
//Create new product => /ap1/v1/product/new
exports.newProduct = async(req, res, next) => {
    const product = await Product.create(req.body);

    res.status(201).json({
        success: true,
        product:
    })
}

exports.getProducts = (req, res, next) => {
    res.status(200).json({
        success: true,
        message: 'This route will show all produts in database.'

    })
}

2. This is my package.json file

{
    "name": "shopit",
    "version": "1.0.0",
    "description": "e-commerce using MERN",
    "main": "server.js",
    "scripts": {
        "start": "node backend/server.js",
        "dev": "SET NODE_ENV=DEVELOPMENT& nodemon backend/server",
        "prod": "nodemon ./server.js localhost 8080: "

    },
    "author": "Floyd",
    "license": "ISC",
    "dependencies": {
        "dotenv": "^8.2.0",
        "express": "^4.17.1",
        "mongoose": "^5.11.13"
    },
    "devDependencies": {
        "nodemon": "^2.0.7"
    }
}

3. This is my server.js file

const app = require('./app');
const connectDatabase = require('./config/database')
const dotenv = require('dotenv');
//Setting up config files
dotenv.config({ path: 'backend/config/config.env' })
//Connecting to database
connectDatabase();
app.listen(process.env.PORT, () => {
    console.log(`Server started on PORT: ${process.env.PORT} in ${process.env.NODE_ENV} 
mode.`)
});

4. This is my routes file

const express = require('express');
const router = express.Router();
const { getProducts, newProduct } = require('../controllers/productController');
router.route('/products').get(getProducts);
router.route('/product/new').post(newProduct);
module.exports = router;

This is my error:

D:\PROGRAMMING\2077\SHOPIT\backend\controllers\productController.js:12
    })
    ^

Answer 1

you should remove the colon from the newProduct function like so

exports.newProduct = async (req, res, next) => {
  const product = await Product.create(req.body);
  res.status(201).json({
    success: true,
    product 
  });
};
