I have just started learning about MongoDB and I am trying to host my node js application locally via MongoDB Server 6.0 (without using mongoose or atlas)
I copied the async javascript code given in the MongoDB docs. I made sure to run mongod before executing the below code MongoDB server started
const { MongoClient } = require("mongodb");
// Connection URI
const uri =
"**mongodb://localhost:27017**";
// Create a new MongoClient
const client = new MongoClient(uri);
async function run() {
try {
// Connect the client to the server (optional starting in v4.7)
await client.connect();
// Establish and verify connection
await client.db("admin").command({ ping: 1 });
console.log("Connected successfully to server");
} finally {
// Ensures that the client will close when you finish/error
await client.close();
}
}
run().catch(console.dir);
It's throwing an error: image of the error it's throwing
CodePudding user response:
Problem is, the localhost
alias resolves to IPv6 address ::1
instead of 127.0.0.1
However, net.ipv6
defaults to false
.
The best option would be to start the MongoDB with this configuration:
net:
ipv6: true
bindIpAll: true
or
net:
ipv6: true
bindIp: localhost
Then all variants should work:
C:\>mongosh "mongodb://localhost:27017?authSource=admin" --quiet --eval "db.getMongo()"
mongodb://localhost:27017/?authSource=admin&directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh 1.6.0
C:\>mongosh "mongodb://127.0.0.1:27017?authSource=admin" --quiet --eval "db.getMongo()"
mongodb://127.0.0.1:27017/?authSource=admin&directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh 1.6.0
C:\>mongosh "mongodb://[::1]:27017?authSource=admin" --quiet --eval "db.getMongo()"
mongodb://[::1]:27017/?authSource=admin&directConnection=true&appName=mongosh 1.6.0
