What is wrong in my code that is causing MongoDB topology error
> db.createCollection('P12345');
{ "ok" : 0, "errmsg" : "collection already exists", "code" : 48 }
> db.createCollection('P123456');
{ "ok" : 1 }
> db.createCollection('P123451');
{ "ok" : 1 }
I'm trying to do same create, a collection using mongo native driver & node.js
MongoClient.connect(url,{ useNewUrlParser: true },(err,client)=>{
if(err){
console.log(err);
}
const db = client.db('Customers');
db.createCollection('P987654321').then((result)=>{
console.log(result);
}).catch((err)=>{
console.log(err);
});
client.close();
})
But I see the below error form running this code block.
{ MongoError: topology was destroyed

OK I found removing client.close(); resolves the topology error but the output is something different a 2000+ lines of JSON is there a better way to find if collection is created because the output is same even if collection exists.

You could use listCollections to find out if a collection already exists: mongodb.github.io/node-mongodb-native/2.0/api/…
