Web Dashboard Access

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

1. Local Environment: Open your web browser and visit http://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).

Note

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)://YourServerIP:CustomPort/YourCustomPath

Proxy Middleware Configuration

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

Custom Logging Functions

log / info

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.

Example

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);

alert

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.

Example

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

error

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

Example

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

warn

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

Example

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

debug

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

Example

errsole.debug('Debugging information');

meta

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.).

Example

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

Note

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