What are @microsoft/applicationinsights-common's main functionalities?

Telemetry Types

This feature provides various telemetry types such as EventTelemetry and ExceptionTelemetry, which are used to log different kinds of telemetry data.

const { EventTelemetry, ExceptionTelemetry } = require('@microsoft/applicationinsights-common');

const eventTelemetry = new EventTelemetry('myEvent');
const exceptionTelemetry = new ExceptionTelemetry(new Error('Something went wrong'));

console.log(eventTelemetry);
console.log(exceptionTelemetry);

Enums

This feature includes enums like SeverityLevel, which can be used to categorize the severity of telemetry data.

const { SeverityLevel } = require('@microsoft/applicationinsights-common');

console.log(SeverityLevel.Critical);
console.log(SeverityLevel.Warning);

Utility Functions

This feature provides utility functions such as Util.isArray and Util.isString, which are helpful for type checking and other common operations.

const { Util } = require('@microsoft/applicationinsights-common');

const isArray = Util.isArray([1, 2, 3]);
const isString = Util.isString('hello');

console.log(isArray); // true
console.log(isString); // true

applicationinsights

The 'applicationinsights' package is the main Application Insights SDK for Node.js. It provides comprehensive functionalities for tracking and monitoring Node.js applications, including telemetry collection, dependency tracking, and performance monitoring. It is more feature-rich compared to @microsoft/applicationinsights-common, which focuses on common types and utilities.

winston

Winston is a popular logging library for Node.js. It provides a flexible and extensible logging system with support for multiple transports, log levels, and formats. While it does not offer the same telemetry-specific features as @microsoft/applicationinsights-common, it is widely used for general logging purposes.

log4js

Log4js is another logging library for Node.js, inspired by the Java log4j library. It offers a variety of appenders for different logging outputs and supports log levels and configuration. Similar to winston, it focuses on general logging rather than telemetry data.
