@json-express/logger-console

The default, zero-dependency console logger for the JSONExpress meta-framework.

📦 Overview

@json-express/logger-console provides the "Batteries Included" logging experience for JSONExpress. It is designed to be lightweight, fast, and completely free of external dependencies.

It implements the ILogger interface using standard console.log, console.warn, and console.error methods, making it perfect for development, local testing, and simple deployments.

🚀 Key Features

• Zero Dependencies: Keeps your node_modules lean.
• Contract Compliant: Implements the standardized JSONExpress ILogger interface.
• Child Logger Support: Allows components to create scoped loggers with context.
• Framework Fallback: Automatically used by the CLI if no other logger is installed.

🛠️ Configuration

While this logger is basic, it respects the following framework-level configurations:

• NODE_ENV: In production, debug logs are suppressed.

💻 Manual Usage

If you are building a custom instance of JSONExpress without the CLI:

import { JsonExpressKernel } from '@json-express/core';
import { ConsoleLogger } from '@json-express/logger-console';

const kernel = new JsonExpressKernel();
const logger = new ConsoleLogger();

kernel.registerLogger(logger);
logger.info('Logger initialized manually');

📜 Standardized Interface

export interface ILogger {
    info(message: string, context?: any): void;
    warn(message: string, context?: any): void;
    error(message: string, context?: any): void;
    debug(message: string, context?: any): void;
    child(context: any): ILogger;
}
