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 />);@sentry/react exports an ErrorBoundary component that will automatically send Javascript errors from inside a
component tree to Sentry, and set a fallback UI. Requires React version >= 16.
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;@sentry/react exports a Profiler component that leverages the @sentry/apm Tracing integration to add React related
spans to transactions. If the Tracing integration is not enabled, the Profiler component will not work. The Profiler
tracks component mount, render duration and updates. Requires React version >= 15.
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);
