Want to call an api to get the data from mongodb in json format but getting in raw format, using javascript, node.js, express, mongodb

Question

This is how I'm connecting to the database:

> //Connecting Mongodb using mongoclient
> 
> const MongoClient = require('mongodb').MongoClient
> 
> const url = 'url is used'
> 
> const dbName = 'virtualcso'
> 
> let db
> 
> // Conforming the database is connected
> 
> MongoClient.connect(url, { useNewUrlParser: true }, (err, client) => {
> 
>   if (err) return console.log(err)
> 
>   // Storing a reference to the database so you can use it later
> 
>   db = client.db(dbName)
> 
>   console.log(`Connected MongoDB: ${url}`)
> 
>   console.log(`Database: ${dbName}`) })

and this is the api calling

> // api to fetch the data from the Mongodb
> 
>   app.get('/fetch', function (req, res) {
> 
>     // getting all the data
> 
>     db.collection('sectester_zap')
> 
>       .find()
> 
>       .toArray(function (err, items) {
> 
>         res.json(items);
> 
>       })   })

and this is how I'm getting the result **

[{"_id":"600bc689bee1c602a89713d1","@version":"2.10.0","@generated":"Wed, 13 Jan 2021 20:21:56","site":[{"@name":"http://demo.testfire.net","@host":"demo.testfire.net","@port":"80","@ssl":"false","alerts":[{"pluginid":"10021","alertRef":"10021","alert":"X-Content-Type-Options Header Missing","name":"X-Content-Type-Options Header Missing","riskcode":"1","confidence":"2","riskdesc":"Low (Medium)","desc":"

The Anti-MIME-Sniffing header X-Content-Type-Options was not set to 'nosniff'. This allows older versions of Internet Explorer and Chrome to perform MIME-sniffing on the response body, potentially causing the response body to be interpreted and displayed as a content type other than the declared content type. Current (early 2014) and legacy versions of Firefox will use the declared content type (if one is set), rather than performing MIME-sniffing.

I need to get this data in json format *

Without being well versed with MongoDB, by the looks of it you are getting the result as JSON and then you are putting it in an array.

And from what I can find looking around, .find() will return a cursor to all documents in a JSON format, so consider if you actually need to use.toArray() in your solution.

I looked among others here: https://www.guru99.com/mongodb-query-document-using-find.html They are using in their example.forEach(printjson) to show their results.

Your example adding this to test the output would look like:

// api to fetch the data from the Mongodb

app.get('/fetch', function (req, res) {

 // getting all the data db.collection('sectester_zap').find().forEach(printjson)

})
