Store array of string into the mongoDB collection - mongodb

Question

I am very new to MongoDB and mongoose I have a model name called agent
agent.model.js
const mongoose = require('mongoose')
const agentSchema = new mongoose.Schema({
agent: {
type: String,
required: true
}
})
const Agent = mongoose.model('Agent', agentSchema)
module.exports = Agent;
Now I have a array of string:
const agentName = ['john', 'alex', 'david'];
Now I want to store this array into the mongoDB as an individual agent.
like this:
[
{
"_id": "6000977d9b94f52960955066",
"agent": "john",
"__v": 0
},
{
"_id": "6000977d9b94f52960955067",
"agent": "alex",
"__v": 0
},
{
"_id": "6000977d9b94f52960955068",
"agent": "david",
"__v": 0
}
]
Note: Right now First I am converting my array of string into the array of object using loop like this:
agentName = agentName.map((e) => {return {agent: e}})
//output of above line of code
[ { agent: 'Alex Watson' },
{ agent: 'John Snow' },
{ agent: 'Rita Ora' } ]
Then I am saving the agentName.
But I am looking for some better approach, Like in which there is no need of converting the array of string into the array of object.

Answer 1

you must to use insertMany() function is used to insert multiple documents into a collection. It accepts an array of documents to insert into the collection. like following code, so have to create a array of abjects, that you created
note: in your question define const agentName next step assign result of map to the constant variable, so this is wrong
const agentName = ['john', 'alex', 'david'];
let arr = agentName.map((e) => {return {agent: e}})
Agent.insertMany(arr).then(function(){
console.log("Data inserted") // Success
}).catch(function(error){
console.log(error) // Failure
});
