Sprawdź, czy kolekcja istnieje w bazie danych MongoDB Mongoose
const mongoose = require('mongoose');
const mongoURI = 'mongodb://localhost:27017/mydb'
// notice the mongoose.createConnection instead of mongoose.connect
const conn = mongoose.createConnection(mongoURI);
conn.on('open', function () {
conn.db.listCollections().toArray(function (err, collectionNames) {
if (err) {
console.log(err);
return;
}
console.log(collectionNames);
conn.close();
});
});
