I'm working on an extremely simple CRUD backend using Express and MongoDB. It doesn't even have a frontend and I'm just using Postman to verify that each request is working as expected. Here's what my single-page app looks like so far:
server.js
const express = require('express')
const bodyParser = require('body-parser')
const MongoClient = require('mongodb').MongoClient
let ObjectId = require('mongodb').ObjectId;
const app = express()
const uri = 'mongodb+srv://<USER>:<PW>@<REDACTED>.mongodb.net/test?retryWrites=true'
let db
MongoClient.connect(uri, { useNewUrlParser: true }, (err, client) => {
if (err) return console.log(err)
db = client.db(<COLLECTION_NAME>)
app.listen(3000, () => {
console.log('Listening on port 3000')
})
})
app.put('/todo', (req, res) => {
db.collection('todo').updateOne({_id:
ObjectId(req.body.id)}, {
$set: {item: req.body.value}
}, (err, result) => {
if (err) return console.log(err)
res.send('Todo updated')
})
})
I've already populated my cluster's collection in MongoDB Atlas using a POST request (not shown) that works. Here is what I've been trying in Postman after running the server locally:
The id of the existing Todo is well-defined in the Atlas cluster, but when I log the value of req.body.value in the first line of the callback function of the PUT request in server.js, it's showing the existing value that's in the Todo in that cluster, not what's actually being supplied via Postman. Why is the request body from Postman not being recognized for this request?
