Raven Log
A lightweight logging utility for sending logs to a configured endpoint.
Installation
Use the package manager npm to install Raven.
npm install raven-log
Usage
1. Importing and Initializing Raven
To start using Raven, first import it and create an instance with your specific configuration.
import raven, { RavenLog } from 'raven-log';
// Create an instance of Raven with your configuration
const ravenInstance = raven.create({
apiUrl: 'https://your-backend-api-url', // The backend endpoint for sending logs
application: 'Your App Name', // The name of your application
});
2. Creating a Log Entry
Once you have an instance, create individual log entries using the RavenLog class. Each log entry allows for customizable properties.
const ravenLog = new RavenLog({
shortDescription: 'This is a 404 test log', // Required, brief description of the log
detailedDescription: 'This is the longer description of the 404 test log which occurred...', // Optional, detailed description
service: 'Your Service Which Produced The Log', // Optional, name of the service responsible
level: 2, // Optional, severity level of the log (e.g., 1 = Info, 2 = Warning, 3 = Error)
user: 'John Doe', // Optional, user associated with the log
path: '/some-super-test-route', // Optional, route or path related to the log event
statusCode: 404, // Optional, HTTP status code (if applicable)
timestamp: Date.now() / 1000; // Optional default is in Unix seconds -> Date.now() / 1000
});
3. Using Raven Log
With your log entry created, you can use the following methods with your ravenInstance.
// Display the log in the console
ravenInstance.console(ravenLog);
// Send the log to the backend API specified in the instance's configuration
ravenInstance.send(ravenLog);
// Display the current configuration of the instance in the console
ravenInstance.showConfig();
// Show the Raven logo in the console
ravenInstance.showRavenArt();
Example
import raven, { RavenLog } from 'raven-log';
// Initialize an instance
const ravenInstance = raven.create({
apiUrl: 'https://your-backend-api-url',
application: 'Example App',
});
// Create a log entry
const exampleLog = new RavenLog({
shortDescription: 'Example log entry',
detailedDescription: 'Detailed information about this log entry...',
service: 'Example Service',
level: 1,
user: 'Alice Doe',
path: '/example-path',
statusCode: 400,
});
// Log to console and send to API
ravenInstance.console(exampleLog);
ravenInstance.send(exampleLog);
// Display config and show the logo
ravenInstance.showConfig();
ravenInstance.showRavenArt();
