If you prefer to follow video instructions, see How to Install the Sentry React SDK in 60 Seconds.

Install

Sentry captures data by using an SDK within your application’s runtime.

Copied
npm install --save @sentry/react

Configure

Configuration should happen as early as possible in your application's lifecycle.

Sentry supports multiple versions of React Router. See the React Router Integration docs for information on how to configure Sentry with React Router.

Copied
import { createRoot } from "react-dom/client";
import { createBrowserRouter } from "react-router-dom";
import React from "react";
import * as Sentry from "@sentry/react";
import App from "./App";

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
  integrations: [
    new Sentry.BrowserTracing({
      // See docs for support of different versions of variation of react router
      // https://docs.sentry.io/platforms/javascript/guides/react/configuration/integrations/react-router/
      routingInstrumentation: Sentry.reactRouterV6Instrumentation(
        React.useEffect,
        useLocation,
        useNavigationType,
        createRoutesFromChildren,
        matchRoutes
      ),
    }),
    new Sentry.Replay()
  ],

  // Set tracesSampleRate to 1.0 to capture 100%
  // of transactions for performance monitoring.
  tracesSampleRate: 1.0,

  // Set `tracePropagationTargets` to control for which URLs distributed tracing should be enabled
  tracePropagationTargets: ["localhost", /^https:\/\/yourserver\.io\/api/],

  // Capture Replay for 10% of all sessions,
  // plus for 100% of sessions with an error
  replaysSessionSampleRate: 0.1,
  replaysOnErrorSampleRate: 1.0,
});

const container = document.getElementById(“app”);
const root = createRoot(container);
root.render(<App />);

Once this is done, all unhandled exceptions are automatically captured by Sentry.

Add Error Boundary

If you're using React 16 or above, you can use the Error Boundary component to automatically send Javascript errors from inside a component tree to Sentry, and set a fallback UI.

Set Up React Router

Add Readable Stack Traces to Errors

Depending on how you've set up your JavaScript

projectRepresents your service in Sentry and allows you to scope events to a distinct application.
, the stack traces in your Sentry errors probably don't look like your actual code.

To fix this, upload your source maps to Sentry. The easiest way to do this is to use the Sentry Wizard:

Copied
npx @sentry/wizard@latest -i sourcemaps

The wizard will guide you through the following steps:

  • Logging into Sentry and selecting a
    projectRepresents your service in Sentry and allows you to scope events to a distinct application.
  • Installing the necessary Sentry packages
  • Configuring your build tool to generate and upload source maps
  • Configuring your CI to upload source maps

For more information on source maps or for more options to upload them, head over to our Source Maps documentation.

Verify

This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.

Copied
<button
  type="button"
  onClick={() => {
    throw new Error("Sentry Test Error");
  }}
>
  Break the world
</button>

To view and resolve the recorded error, log into sentry.io and open your

. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
