Sentry's SDKs enable automatic reporting of errors and exceptions.
On this page, we get you up and running with Sentry's SDK.
If you're seeing deprecation warnings in your code, please note that we're currently working on version 8 of the JavaScript SDKs. In v8, some methods and properties will be removed or renamed. Check out the Migration docs and learn how to update your code to be compatible with v8.

If you prefer to follow video instructions, see How to Install the Sentry Node SDK in 60 Seconds.
Sentry captures data by using an SDK within your application’s runtime.
npm install --save @sentry/node
Configuration should happen as early as possible in your application's lifecycle.
Once this is done, Sentry's Node SDK captures all transactions and unhandled exceptions.
import * as Sentry from "@sentry/node";
Sentry.init({
dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
// We recommend adjusting this value in production, or using tracesSampler
// for finer control
tracesSampleRate: 1.0,
});
Depending on how you've set up your project, 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:
npx @sentry/wizard@latest -i sourcemaps
The wizard will guide you through the following steps:
- Logging into Sentry and selecting a project
- 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.
This snippet includes an intentional error, so you can test that everything is working as soon as you set it up.
Sentry.startSpan({
op: "test",
name: "My First Test Transaction",
}, () => {
setTimeout(() => {
try {
foo();
} catch (e) {
Sentry.captureException(e);
}
}, 99);
});
Learn more about manually capturing an error or message in our Usage documentation.
To view and resolve the recorded error, log into sentry.io and open your project. Clicking on the error's title will open a page where you can see detailed information and mark it as resolved.
Our documentation is open source and available on GitHub. Your contributions are welcome, whether fixing a typo (drat!) or suggesting an update ("yeah, this would be better").
