loggly-jslogger is a JavaScript logging library designed to send logs to Loggly, a cloud-based log management service. This package allows developers to easily integrate logging into their applications, ensuring that important events and errors are captured and sent to a centralized logging service for analysis and monitoring. While loggly-jslogger is a great choice for applications that specifically want to utilize Loggly, there are several other logging libraries available that offer different features and capabilities. Here are a few alternatives:

  • bunyan is a simple and fast JSON logging library for Node.js applications. It provides a structured logging format, making it easy to filter and query logs. Bunyan supports log levels, streams, and serializers, allowing developers to customize their logging output. It is particularly useful for server-side applications that require detailed and structured logs for debugging and monitoring.
  • debug is a lightweight logging utility that allows developers to enable or disable logging based on namespaces. It is commonly used in Node.js and browser applications for debugging purposes. With debug, you can control the verbosity of logs without modifying the code, making it a flexible choice for development and production environments.
  • log4js is a logging library inspired by the popular log4j framework. It provides a variety of appenders (e.g., console, file, and SMTP) and supports log levels, categories, and layouts. Log4js is suitable for both client-side and server-side applications, offering a comprehensive solution for managing logs in different environments.
  • loglevel is a minimalistic logging library that provides a simple API for logging messages at different levels (trace, debug, info, warn, error). It is lightweight and easy to use, making it a good choice for projects that require basic logging functionality without the overhead of more complex libraries.
  • morgan is an HTTP request logger middleware for Node.js applications. It is commonly used with Express.js to log incoming requests and their details. Morgan provides predefined formats for logging and can be easily customized to suit the needs of your application.
  • pino is a fast and low-overhead JSON logger for Node.js applications. It is designed for performance and provides a simple API for logging messages. Pino supports log levels, serializers, and transports, making it a versatile choice for applications that require efficient logging.
  • winston is a popular logging library for Node.js that supports multiple transports (e.g., console, file, HTTP) and log levels. It allows developers to create custom log formats and manage logs in a structured way. Winston is highly configurable and suitable for both small and large applications.

README for loggly-jslogger

loggly-jslogger

Client-side (browser) logger to send Javascript logs from any website to Loggly. Check out Loggly’s Javascript logging documentation to learn more.

Installation

Insert the following code into your webpage, replacing your-customer-token with the key defined in the Source Setup -> Customer Tokens page:

<script type="text/javascript" src="https://cloudfront.loggly.com/js/loggly.tracker-2.2.4.min.js" async></script>
<script>
  var _LTracker = _LTracker || [];
  _LTracker.push({
    'logglyKey': 'your-customer-token',
    'sendConsoleErrors': true,
    'tag': 'javascript-logs'
  });
</script>

To get early access to the most recent updates to the tracker, use the script https://cloudfront.loggly.com/js/loggly.tracker-latest.min.js. This is not recommended in a production environment as it may include breaking changes.

Usage

Logging text:

_LTracker.push('my tracking string');

Logging JSON:

_LTracker.push({
  'text': 'my tracking string',
  'aList': [9, 2, 5],
  'anObject': {
    'id': 1,
    'value': 'foobar'
  }
});

Customization

Separate logging instance:

var myBetterLogger = new LogglyTracker();
myBetterLogger.push({'logglyKey': 'your-customer-token' });  // push a loggly key to initialize

Send Console Errors to Loggly

Keep the sendConsoleErrors value to true to send all unhandled errors to Loggly with detailed information, including error message, URL, line number and column number.

Send Tags to Loggly

Send your custom tags to Loggly by setting the tag property.

_LTracker.push({
  'logglyKey': 'your-customer-token',
  'sendConsoleErrors' : true,
  'tag' : 'tag1,tag2'
});

Special Characters Support

Set the useUtfEncoding value to true to prevent special characters from showing as odd or unusual characters in Loggly Search. Special characters will be easier to read and understand in your log events.

See the usage below:

_LTracker.push({
  'logglyKey': 'your-customer-token',
  'sendConsoleErrors' : true,
  'tag' : 'javascript-logs',
  'useUtfEncoding': true
});

Setup Proxy for Ad blockers

If the script or its requests are blocked by ad blockers, you can proxy requests from your own domain. To do this, perform following steps

Set useProxyDomain property to true

_LTracker.push({
  'logglyKey': 'your-customer-token',
  'sendConsoleErrors' : true,
  'tag' : 'javascript-logs',
  'useDomainProxy' : true
});

Use the following configuration on your server to forward the requests to Loggly

#Proxy to Loggly
location /loggly/ {
    rewrite ^/loggly/(.*)$ /$1 break;  # remove the '/loggly' part from the path, leaving /inputs/xxxxxxxx-xxxx-.../tag/xxx
    proxy_set_header Host logs-01.loggly.com;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $remote_addr;
    proxy_pass http://logs-01.loggly.com;
}
