@sentry/utils

What is @sentry/utils?

The @sentry/utils package provides a collection of utility functions and classes that are used across the Sentry JavaScript SDK. These utilities help with various tasks such as data manipulation, browser and node environment checks, and integration with Sentry's error tracking and performance monitoring features.

What are @sentry/utils's main functionalities?

Data Manipulation

Provides utility functions for checking data types and manipulating data. For example, the `isString` function can be used to check if a variable is a string.

import { isString } from '@sentry/utils';

function logMessage(message) {
  if (isString(message)) {
    console.log(message);
  } else {
    console.log('Not a string');
  }
}

Environment Checks

Includes functions to check the current runtime environment, such as whether the code is running in a browser or Node.js environment. This is useful for writing isomorphic code that runs both on the client and server.

import { isNodeEnv } from '@sentry/utils';

if (isNodeEnv()) {
  console.log('Running in a Node environment');
} else {
  console.log('Not running in a Node environment');
}

Integration Helpers

Provides functions and classes to help integrate with Sentry, including adding global event processors that can modify or filter events before they are sent to Sentry.

import { addGlobalEventProcessor } from '@sentry/utils';

addGlobalEventProcessor(event => {
  // Modify the event object or return null to skip sending the event
  return event;
});

Other packages similar to @sentry/utils

lodash

Lodash is a comprehensive utility library offering a wide array of functions for tasks like data manipulation, array and object operations, and more. While it doesn't provide direct integrations with error tracking systems, its broad utility function set makes it a versatile tool for many of the same data manipulation tasks as @sentry/utils.

debug

The debug package is used for logging debug messages in a development environment. It doesn't offer the same utility functions or Sentry integration as @sentry/utils, but it's useful for debugging applications in development, similar to how one might use Sentry's logging and error tracking in production.
