Prerequisites

Before we proceed, make sure you have the following prerequisites in place:

1. Node.js installed on your machine.
2. A valid Loggly account.

Setting up Loggly

To get started, you need to create a new Loggly HTTP/S endpoint to receive logs from your Node.js application. Follow these steps to set it up:

1. Log in to your Loggly account.
2. Go to the Source Setup section and click on HTTP/S.
3. Click on Add New Endpoint.
4. Give your endpoint a name and choose the desired log format (e.g., JSON).
5. Click on Save to create your endpoint.
6. Note down the provided Endpoint URL.

Installing Loggly library

Next, we need to install the Loggly library to send logs from our Node.js application to Loggly seamlessly. Open your terminal or command prompt and navigate to your project folder. Then, run the following command:

npm install loggly

This command will install the Loggly library and add it to your package.json file.

Configuring Loggly in your Node.js application

To configure Loggly in your Node.js application, follow these steps:

1. Open your application’s main file (e.g., app.js or index.js).

2. Require the Loggly library:

   const loggly = require('loggly');
   

3. Create a new Loggly client and configure it using your endpoint URL and any additional options:

   const client = loggly.createClient({
     token: 'YOUR_LOGGLY_TOKEN',
     subdomain: 'YOUR_LOGGLY_SUBDOMAIN',
     endpoint: 'YOUR_LOGGLY_ENDPOINT_URL',
     tags: ['production', 'nodejs-app']
   });
   

   Make sure to replace the YOUR_LOGGLY_TOKEN, YOUR_LOGGLY_SUBDOMAIN, and YOUR_LOGGLY_ENDPOINT_URL placeholders with your actual Loggly credentials and endpoint URL.

4. Start logging messages to Loggly using the created client:

   client.log('info', 'This is a test log message', { someData: 'example' });
   

   The first parameter represents the log level (e.g., ‘info’, ‘error’, ‘debug’), the second parameter is the log message, and the third parameter is an optional object containing additional data.

Viewing logs in real-time

With Loggly successfully configured in your Node.js application, you can now view your logs in real-time. Log in to your Loggly account and navigate to the Logs section. You should see your logs streaming in as they are generated by your application.

Conclusion

By integrating Loggly into your Node.js applications, you can easily implement real-time logging and gain valuable insights into your application’s behavior. This allows you to identify and resolve issues quickly, improving the overall stability and performance of your Node.js applications.
