@push.rocks/smartlog-interfaces

interfaces for the smartlog ecosystem

Install

To install @push.rocks/smartlog-interfaces, ensure you have Node.js and npm installed. Then, run the following command in your project directory:

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

This command adds @push.rocks/smartlog-interfaces to your package's dependencies and downloads it into the node_modules folder.

Usage

@push.rocks/smartlog-interfaces provides TypeScript interfaces for structuring log messages within the Smartlog ecosystem. These interfaces standardize how log data is structured and transmitted across different parts of a system, making it easier to collect, query, and analyze logs.

The Smartlog ecosystem is designed to support a versatile range of logging needs, from simple application logs to complex, structured data logging for microservices. To utilize these interfaces in your project, follow the steps below:

Setting Up

First, ensure you're using TypeScript in your project. Install TypeScript if you haven't already:

npm install typescript --save-dev

Then, import the necessary interfaces from the package in your logging module or any place you intend to produce logs:

import {
  ILogPackage,
  ILogDestination,
  TLogLevel,
  TLogType,
  ILogContext,
  TRuntime,
  TEnvironment,
  ILogCorrelation
} from '@push.rocks/smartlog-interfaces';

Creating a Log Message

Here's how to create a log package conforming to the ILogPackage interface:

const myLogContext: ILogContext = {
  environment: 'production' as TEnvironment,
  runtime: 'node' as TRuntime,
  zone: 'eu-central-1'
};

const myLogCorrelation: ILogCorrelation = {
  id: '123456789',
  type: 'service'
};

const myLogPackage: ILogPackage = {
  timestamp: Date.now(),
  type: 'log' as TLogType,
  context: myLogContext,
  level: 'info' as TLogLevel,
  correlation: myLogCorrelation,
  message: 'This is a sample log message.',
};

In this example, myLogPackage encapsulates all the required data for a log message, including contextual data about where and when the log was generated.

Implementing ILogDestination

ILogDestination is an interface that defines how log packages are handled. You can implement your own log destination (e.g., a cloud-based logging service, local log file writer) by conforming to this interface.

class MyLogService implements ILogDestination {
  async handleLog(logPackage: ILogPackage): Promise<void> {
    // Implement log handling logic here.
    // For demonstration, we'll simply log to the console.
    console.log(JSON.stringify(logPackage));
  }
}

// Usage
const myLogService = new MyLogService();
await myLogService.handleLog(myLogPackage);

This basic implementation of ILogDestination offers a foundational structure on which you can build more sophisticated log handling mechanisms, like batch processing, filtering, or routing based on log metadata.

Extending Functionality

The interfaces provided by @push.rocks/smartlog-interfaces serve as a starting point. In a complex application or service, you might need to extend these interfaces with additional properties or create new interfaces that extend these base interfaces to include more specific log data relevant to your application.

Custom Log Data

For example, if your application needs to log request-specific information, you could extend ILogPackage:

interface ILogPackageWithRequestData extends ILogPackage<ILogPackageDataRequest> {
  // You can add more fields or override existing ones
}

// Then, when creating a log package:
const myLogPackageWithRequestData: ILogPackageWithRequestData = {
  // Include all required fields from ILogPackage
  // And add your additional request-specific log data in the 'data' field
};

Conclusion

@push.rocks/smartlog-interfaces provides the foundation for consistent and structured logging across your applications and services. By adhering to the interfaces defined in the package, you can ensure that your logs are standardized, making them easier to query, analyze, and understand. Whether you're developing a small application or a large, distributed system, these interfaces offer the flexibility and structure needed to implement robust logging practices.
