Having trouble sending messages on the server?

Question

Having trouble sending messages on the server?

Programmer Seeking Help with Adding Data on the Server using JavaScript Stack I am encountering an issue with my javascript code as I am attempting to use the post method to add data on the server-side, but it seems to not be posting successfully. Can someone guide me on what changes I can make to rectify this problem?


        const express = require('express');
        const cors = require('cors');
        const { MongoClient, ServerApiVersion, ObjectId } = require('mongodb');
        require('dotenv').config()
        const app = express();
        
        app.use(cors());
        app.use(express());

        app.post('/items', async (req, res) => {
            const newItem = req.body;
            console.log(newItem);
            const result = await laptopCollection.insertOne(newItem);
            res.send(result);
        })

The potential cause of the issue could be related to missing middleware in my implementation.


        app.use(cors());
        app.use(express());

Answer №1

The recommended middleware to use:

app.use(cors())
app.use(express.json())

Creating a post with async function

async function executePost() {
    try {
        await client.connect();
        const laptopCollection = client.db('database_name').collection('collection_name');

         app.post('/items', async (req, res) => {
            const newItem = req.body;
            console.log(newItem);
            const result = await laptopCollection.insertOne(newItem);
            res.send(result);
        })
    } finally {
        // await client.close();
    }
}
executePost().catch(console.error);

app.use(express()) function is unable to parse incoming JSON requests and store the parsed data in req.body.To. To resolve this issue, adjust the function as follows:

app.use(express.json())

In addition, you have overlooked importing the async function. Make sure to include the following code snippets:

async function run() 
{
  try {
    await client.connect();
    const laptopCollection = client.db('database_name').collection('collection_name');
    app.post('/items', async (req, res) => {
      const newItem = req.body;
      console.log(newItem);
      const result = await laptopCollection.insertOne(newItem);
      res.send(result);
    })
  } 
}
