useUnifiedTopology: true,
useFindAndModify: false
})
.then(() => console.log('Connected Successfully'))
.catch((err) => console.error('Not Connected'));
}
module.exports = connectDB;
Ejemplo 3: conexión de mangosta
mongoose.connect('mongodb://localhost:27017/test', {
useMongoClient: true,
connectTimeoutMS: 1000
})
Ejemplo 4: nodo de conexión de mangosta
mongoose.connect('mongodb://localhost/myapp', { useNewUrlParser: true, useUnifiedTopology: true });
Ejemplo 5: el nodo js se conecta a mongodb usando mongoose
//connect with mongodb
mongoose.connect('mongodb://localhost:27017/your_db_name', {useNewUrlParser: true});
