React monitoring for developers

Getting started is simple

Grab the Sentry React SDK:

Click to Copy
npm install @sentry/react

We recommend putting the Sentry initialization code into its own file and including that file as the first import in your application entry point as shown in the example below:

Click to Copy
import { useEffect } from "react"; import * as Sentry from "@sentry/react"; Sentry.init({ dsn: "https://[email protected]/0", integrations: [ ], // Set `tracePropagationTargets` to control for which URLs trace propagation should be enabled tracePropagationTargets: [/^\//, /^https:\/\/yourserver\.io\/api/], });

Include the Sentry initialization file as the first import statement:

Click to Copy
// Sentry initialization should be imported first! import "./instrument"; import App from "./App"; import { createRoot } from "react-dom/client"; const container = document.getElementById(“app”); const root = createRoot(container); root.render(<App />);

That's it. Check out our documentation to ensure you have the latest instructions.
