General

This package is a wrapper around @sentry/browser, with added functionality related to React. All methods available in @sentry/browser can be imported from @sentry/react.
To use this SDK, call Sentry.init(options) before you mount your React component.

import React from 'react';
import ReactDOM from 'react-dom';
import * as Sentry from '@sentry/react';

Sentry.init({
  dsn: '__DSN__',
  // ...
});

// ...

ReactDOM.render(<App />, rootNode);

// Can also use with React Concurrent Mode
// ReactDOM.createRoot(rootNode).render(<App />);

ErrorBoundary

@sentry/react exports an ErrorBoundary component that will automatically send Javascript errors from inside a component tree to Sentry, and set a fallback UI.

app.js

import React from 'react';
import * as Sentry from '@sentry/react';

function FallbackComponent() {
  return <div>An error has occured</div>;
}

class App extends React.Component {
  render() {
    return (
      <Sentry.ErrorBoundary fallback={FallbackComponent} showDialog>
        <OtherComponents />
      </Sentry.ErrorBoundary>
    );
  }
}

export default App;

Profiler

@sentry/react exports a Profiler component that leverages the tracing features to add React-related spans to transactions. If tracing is not enabled, the Profiler component will not work. The Profiler tracks component mount, render duration and updates.

app.js

import React from 'react';
import * as Sentry from '@sentry/react';

class App extends React.Component {
  render() {
    return (
      <FancyComponent>
        <InsideComponent someProp={2} />
        <AnotherComponent />
      </FancyComponent>
    );
  }
}

export default Sentry.withProfiler(App);
