mongoose connection increase timeout in node js

Increasing Timeout for Mongoose Connection in Node.js

To increase the timeout for a Mongoose connection in Node.js, you can follow these steps:

  1. Import the Mongoose module: Begin by importing the Mongoose module in your Node.js application. This module allows you to interact with MongoDB using an object data modeling (ODM) approach.

  2. Establish the Mongoose connection: Use the mongoose.connect() method to establish a connection to your MongoDB database. This method takes a connection string as a parameter, which specifies the location of your MongoDB server.

  3. Configure the connection options: To increase the timeout for the Mongoose connection, you can pass additional options to the mongoose.connect() method. One of the options you can set is the connectTimeoutMS option, which specifies the maximum time in milliseconds to wait for a connection to be established.

Here's an example of how you can set the connectTimeoutMS option to increase the timeout to 10 seconds (10,000 milliseconds):

javascript mongoose.connect('mongodb://localhost/mydatabase', { connectTimeoutMS: 10000 });

In the example above, the connectTimeoutMS option is set to 10,000 milliseconds (10 seconds).

  1. Handle connection events: It's a good practice to handle connection events to check if the connection was successful or if an error occurred. You can use the mongoose.connection object to listen for events such as open, error, and disconnected.

Here's an example of how you can handle the open and error events:

```javascript mongoose.connection.on('open', () => { console.log('Connected to MongoDB'); });

mongoose.connection.on('error', (err) => { console.error('MongoDB connection error:', err); }); ```

In the example above, the open event is logged to the console when the connection is successfully established, and the error event logs any connection errors to the console.

That's it! By following these steps, you can increase the timeout for a Mongoose connection in Node.js.
