# How to Add Sentry Integration to your NodeJS App

To add Sentry integration to a Node.js Express app written in TypeScript, you will need to install the Sentry SDK for Node.js and the @sentry/node package:

```typescript
npm install @sentry/node @sentry/tracing
```

Next, you will need to configure the Sentry SDK by creating a `sentry.ts` file in your project and adding the following code:

```typescript
import * as Sentry from '@sentry/node';

export function initializeSentry(dsn: string) {
  Sentry.init({
    dsn,
    tracesSampleRate: 1.0,
  });
}
```

This code initializes the Sentry SDK with the provided DSN and enables full tracing.

To use Sentry in your Express app, you will need to import the `initializeSentry` function and call it at the beginning of your app, passing in the DSN for your Sentry project:

```typescript
import express from 'express';
import { initializeSentry } from './sentry';

const app = express();

initializeSentry(process.env.SENTRY_DSN);

// Add routes and middleware to app...

app.listen(3000, () => {
  console.log('App listening on port 3000');
});
```

Once Sentry is initialized, you can use it to capture errors and events in your app by calling the `Sentry.captureException` and `Sentry.captureMessage` functions, respectively. For example:

```typescript
app.get('/', (req, res) => {
  try {
    // Some code that might throw an exception
  } catch (error) {
    Sentry.captureException(error);
  }
});

app.post('/', (req, res) => {
  Sentry.captureMessage('Something happened');
});
```

This will send the errors and events to your Sentry project, where you can view them and use them to troubleshoot issues in your application.

Overall, integrating Sentry into a Node.js Express app written in TypeScript is relatively straightforward. By installing the necessary packages and configuring the Sentry SDK, you can easily capture errors and events in your app and use them to troubleshoot issues and improve the reliability of your application.  
  
I hope this helps you, set up sentry, to your NodeJS app without any issues.
