log-service-sdk v1.0.3

log-service-sdk

An SDK for interacting with your logging service. It integrates seamlessly with Winston for structured logging and allows sending logs to your logging service with minimal setup.

Features

• Easily integrate with your logging service.
• Supports API token-based authentication.
• Built-in support for Winston.
• Configurable applicationId for grouping logs by application.
• Automatically sends logs to your backend endpoint.

Installation

Install the SDK using NPM:

npm install log-service-sdk

Usage

1. Import and Initialize Logger

Initialize the logger with your applicationId, apiToken, and optionally the endpoint URL:

const { initializeLogger } = require("log-service-sdk");

// Initialize the logger
const logger = initializeLogger(
  "my-app-id",
  "<your-api-token>",
  "https://your-logging-service.com/logs"
);

2. Log Messages

Use the logger to log messages at various levels (info, error, warn, etc.):

// Log an informational message
logger.info("User logged in", { userId: "12345" });

// Log an error message
logger.error("An error occurred", { error: "Something went wrong" });

API

initializeLogger(applicationId, apiToken, endpoint)

• applicationId: A unique identifier for your application (string, required).
• apiToken: API token for authenticating with the logging service (string, required).
• endpoint: URL of the logging service endpoint (string, optional, defaults to http://localhost:5000/logs).

Returns:

• A configured Winston logger instance.

Examples

Basic Example

const { initializeLogger } = require("log-service-sdk");

const logger = initializeLogger("my-app", "your-api-token");

// Log various messages
logger.info("This is an info log");
logger.warn("This is a warning");
logger.error("This is an error", { additionalData: "value" });

Override applicationId for Specific Logs

logger.info("Overriding applicationId", { applicationId: "other-app" });

Error Handling

The SDK handles errors gracefully when sending logs:

• Logs the error to the console using console.error.
• Ensures the logging flow is not interrupted even if the backend is unreachable.
