@push.rocks/smartlog-destination-local

a smartlog destination targeting the local console

Install

To use @push.rocks/smartlog-destination-local in your project, you need to install it via npm. You can do this by running:

npm install @push.rocks/smartlog-destination-local --save

This command adds @push.rocks/smartlog-destination-local to your project's dependencies and enables you to start implementing its features in your application.

Usage

The @push.rocks/smartlog-destination-local package provides a way to easily log messages to the local console with support for color coding and structured message formats. It is especially useful when combined with the @push.rocks/smartlog package to create a powerful logging solution that is both visually informative and structured for better logging practices.

Importing and Setting Up

First, make sure to import the package where you intend to use it:

import { DestinationLocal } from '@push.rocks/smartlog-destination-local';

Next, create an instance of DestinationLocal:

const localLogDestination = new DestinationLocal();

Logging Messages

The primary feature of @push.rocks/smartlog-destination-local is to log messages to the console. This can be done by preparing a log package and using the handleLog method.

Example Log Message

import type { ILogPackage } from '@push.rocks/smartlog-interfaces';

const logPackage: ILogPackage = {
  timestamp: Date.now(),
  type: 'log', // or 'error', 'warn', etc. depending on the nature of the message
  level: 'info', // determines the visibility and importance of the log
  context: {
    company: 'Your Company',
    companyunit: 'Your Unit',
    containerName: 'Your Container',
    environment: 'development',
    runtime: 'node',
    zone: 'Your Zone'
  },
  message: 'This is a test log message.', // the actual message
  correlation: {
    id: 'uniqueId', // useful for tracing logs
    type: 'requestId'
  },
};

// Using the instance to log the message
localLogDestination.handleLog(logPackage);

This will output a structured, color-coded log message to your console, making it easier to differentiate between various log levels and to understand the context of the log messages at a glance.

Log Reduction

For scenarios where repeated log messages may clutter your log output, @push.rocks/smartlog-destination-local offers a logReduced method. This method will throttle the output of identical consecutive messages according to the settings you provide.

Reducing Log Output

// Log a message repeatedly, e.g., in a loop
for (let i = 0; i < 100; i++) {
  localLogDestination.logReduced('Repeated message', 5); // only logs every 5th identical message
}

Adding New Lines

You may want to improve the readability of your logs by inserting blank lines. This can be easily achieved:

localLogDestination.newLine(2); // Inserts two empty lines in the log output

Advanced Use Cases

The @push.rocks/smartlog-destination-local package is flexible and integrates seamlessly with other logging and monitoring solutions. It can be extended or customized to fit more complex logging requirements, such as filtering logs based on environment, enhancing log messages with additional metadata, or integrating with remote logging services for centralized log management.

Conclusion

@push.rocks/smartlog-destination-local serves as a robust, easy-to-use solution for enhancing your application's logging capabilities. By following the examples and using the provided methods, you can quickly implement effective logging practices that improve debugging, monitoring, and analysis of your application's behavior in development and production environments.
