Setup
Web Dashboard Access
Once you have completed the setup, access the Errsole Web Dashboard at http://localhost:8001/. If you have initialized Errsole using a different port or specified a custom path, make sure to adjust the URL accordingly. Replace 8001 with your chosen port and append your custom path at the end of the URL.
Proxy Middleware Configuration
Should you encounter issues accessing port 8001, possibly due to firewall constraints, or if you prefer to host the Errsole Web Dashboard on your primary domain/port, configure the Errsole Proxy Middleware in your app. Follow these steps:
- Specify the custom path for the Errsole Web Dashboard during the initialization of Errsole.
- Integrate the Errsole Proxy Middleware into your app.
Example:
const errsole = require('errsole');
const ErrsoleMongoDB = require('errsole-mongodb');
errsole.initialize({
storage: new ErrsoleMongoDB('mongodb://localhost:27017/', 'logs'),
path: '/errsole'
});
const express = require('express');
const app = express();
app.use(errsole.proxyMiddleware());
app.get('/', function (req, res) {
res.send('Hello World');
});
app.listen(3000);
Once you have done that, you will be able to access the Errsole Web Dashboard using the same domain as your app. For example:
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');
