Errsole is an open-source logger for Node.js. It has a built-in web dashboard to view, filter, and search your app logs.

Just include the Errsole package in your code—no need for dedicated servers, software installations, or complicated configurations.

Errsole automatically collects all logs from the Node.js console. Additionally, it provides a custom logger with multiple log levels and allows you to include metadata with your logs for better context. Read More

Store your logs wherever you want—whether in a file or any database of your choice. You can also configure log rotation to specify how long logs should be retained.

View, filter, and search through your logs using the built-in Web Dashboard. Secure authentication and team management features ensure that only you and your team can access the logs.

Get immediate notifications when your app crashes or encounters critical errors. The notification includes the error message, the app name, the environment, the server name, and a direct link to view the error in your logs.

Errsole's AI Copilot analyzes your error logs, pinpoints the exact location in the code where the error occurred, explains the cause of the error, and suggests a fix.

A Node.js app using Errsole Logger can handle 90,000 more requests per minute than when using Elasticsearch and 70,000 more requests per minute than when using Amazon CloudWatch. Read More

After completing the setup, you can access the Errsole Web Dashboard through the following methods:

1. Local Environment: Open your web browser and visit https://localhost:8001/.
2. Remote Server: If you have deployed Errsole on a remote server, use the server's IP address or domain name followed by the port number (e.g., YourServerIP:8001 or YourDomain:8001).

If you initialized Errsole with a different port or specified a custom path, adjust the URL as follows:

1. Replace 8001 with your chosen port number.
2. Append your custom path to the end of the URL.

http(s):https://YourServerIP:CustomPort/YourCustomPath

If you encounter issues accessing port 8001 due to firewall restrictions, or if you prefer to host the Errsole Web Dashboard on your primary domain/port, you can configure the Errsole Proxy Middleware in your app. Here is a step-by-step guide: Proxy Middleware Configuration

The log function is used to log messages or information. It can accept one or more arguments, which can be strings, numbers, JavaScript objects, or Error objects.

errsole.log('Logging a message');
errsole.log('Multiple', 'arguments', 'are supported');
errsole.log('Logging with a variable:', var1);
errsole.log(new Error('An error occurred'));
errsole.log('Logging with an error object:', errorObject);

The alert function logs a message and sends a notification to configured channels, such as Email or Slack. It accepts the same types of arguments as the log function.

errsole.alert('Alert! Something critical happened');

The error function is specifically designed to log errors. It accepts the same types of arguments as the log function.

errsole.error(new Error('An error occurred'));

The warn function is used to log warning messages. It accepts the same types of arguments as the log function.

errsole.warn('This is a warning message');

The debug function logs debug information, typically used for troubleshooting during development. It accepts the same types of arguments as the log function.

errsole.debug('Debugging information');

In Errsole's custom logger, you can include metadata with your logs. This metadata can be any contextual information, such as HTTP requests or database query results. In the Errsole Web Dashboard, you can view this metadata in a clean JSON viewer without cluttering the log messages.

To include metadata in your logs, use the meta function followed by the appropriate logging function (error, log, etc.).

errsole.meta({ reqBody: req.body, queryResults: results }).error(err);
errsole.meta({ email: req.body.email }).log('User logged in');

The meta function must be the first function in the chain, followed by the desired logging function.
