# Official Sentry SDK for Browsers [![Sauce Test Status](https://saucelabs.com/buildstatus/sentryio)](https://saucelabs.com/u/sentryio) [![npm version](https://img.shields.io/npm/v/@sentry/browser.svg)](https://www.npmjs.com/package/@sentry/browser) [![npm dm](https://img.shields.io/npm/dm/@sentry/browser.svg)](https://www.npmjs.com/package/@sentry/browser) [![npm dt](https://img.shields.io/npm/dt/@sentry/browser.svg)](https://www.npmjs.com/package/@sentry/browser) ## Links - [Official SDK Docs](https://docs.sentry.io/quickstart/) - [TypeDoc](http://getsentry.github.io/sentry-javascript/) ## Usage To use this SDK, call `Sentry.init(options)` as early as possible after loading the page. This will initialize the SDK and hook into the environment. Note that you can turn off almost all side effects using the respective options. ```javascript import * as Sentry from '@sentry/browser'; Sentry.init({ dsn: '__DSN__', // ... }); ``` To set context information or send manual events, use the exported functions of `@sentry/browser`. Note that these functions will not perform any action before you have called `Sentry.init()`: ```javascript import * as Sentry from '@sentry/browser'; // Set user information, as well as tags and further extras Sentry.setExtra('battery', 0.7); Sentry.setTag('user_mode', 'admin'); Sentry.setUser({ id: '4711' }); // Add a breadcrumb for future events Sentry.addBreadcrumb({ message: 'My Breadcrumb', // ... }); // Capture exceptions, messages or manual events Sentry.captureMessage('Hello, world!'); Sentry.captureException(new Error('Good bye')); Sentry.captureEvent({ message: 'Manual', stacktrace: [ // ... ], }); ```
