@push.rocks/smartlog-receiver

a receiver for smartlog-destination-receiver

Install

To install @push.rocks/smartlog-receiver, use the following command with npm:

npm install @push.rocks/smartlog-receiver --save

or with yarn:

yarn add @push.rocks/smartlog-receiver

Ensure that you have TypeScript and Node.js installed in your development environment as this module leverages TypeScript for type definitions.

Usage

The @push.rocks/smartlog-receiver module is designed to receive log messages sent from applications using the smartlog logging system. It allows for centralized logging by receiving, validating, and processing log messages in a secure and controlled manner. Below, we'll go through how to set up and use smartlog-receiver in your project.

Setting up SmartlogReceiver

First, make sure to import SmartlogReceiver from the package, along with the types it depends on if necessary.

import { SmartlogReceiver, ISmartlogReceiverOptions } from '@push.rocks/smartlog-receiver';
import { Smartlog } from '@pushrocks/smartlog';

SmartlogReceiver requires an instance of Smartlog for logging internal messages and potentially logging the received log messages. Ensure you initialize Smartlog first:

const smartlogInstance = new Smartlog({
  logContext: {
    company: 'YourCompany',
    companyunit: 'YourUnit',
    environment: 'production',
    runtime: 'node',
    version: '1.0.0'
  },
  minimumLogLevel: 'info',
});
smartlogInstance.enableConsole(); // Enabling console output for demonstration purposes

Now, instantiate the SmartlogReceiver with the necessary options. You need to provide a passphrase for authentication and a validator function that decides whether to accept or reject incoming messages based on your criteria.

const smartlogReceiver = new SmartlogReceiver({
  smartlogInstance: smartlogInstance,
  passphrase: 'yourSecretPassphrase',
  validatorFunction: async (logPackage) => {
    // Example validation: accept only if message contains 'accepted'
    return logPackage.message.includes('accepted');
  },
});

Handling Log Messages

To handle authenticated log messages, you'd typically have an endpoint in your application that receives log packages. Here, we'll simulate receiving a log package.

import { ILogPackageAuthenticated } from '@pushrocks/smartlog-interfaces';
import * as smarthash from '@pushrocks/smarthash';

// Simulated received log message
const receivedLogPackage: ILogPackageAuthenticated = {
  auth: smarthash.sha256FromStringSync('yourSecretPassphrase'), // Generate hash of your passphrase for authentication
  logPackage: {
    timestamp: Date.now(),
    context: {
      company: 'YourCompany',
      companyunit: 'YourUnit',
      environment: 'production',
      runtime: 'node',
      version: '1.0.0'
    },
    level: 'info',
    type: 'log',
    message: 'This is an accepted log message',
    correlation: {
      id: 'unique-correlation-id',
      type: 'transaction'
    }
  }
};

// Handler function to process received log packages
async function handleReceivedLog(logPackage: ILogPackageAuthenticated) {
  const result = await smartlogReceiver.handleAuthenticatedLog(logPackage);
  console.log(result); // Should output { status: 'ok' } for successfully processed messages
}

handleReceivedLog(receivedLogPackage);

Ensure your validation and handling logic fits the security and architectural needs of your application.

Advanced Usage

  • Batch Processing: SmartlogReceiver also supports processing batches of logs efficiently through the method handleManyAuthenticatedLogs, facilitating bulk log management.

  • Customizing Smartlog: Since SmartlogReceiver uses Smartlog for its operations, you can harness the full power of Smartlog for detailed customization, such as setting up different log destinations, filtering log levels, and more.

By setting up @push.rocks/smartlog-receiver, you're enabling a robust and flexible system to manage your application's logging infrastructure, making it easier to monitor and debug with centralized logs.
