# Get Started Using TypeScript Library

Connects to the XRP Ledger, gets account information, builds and validates a typed transaction, and subscribes to ledger events using TypeScript and `xrpl.js`.

To download the source code, see the [Get Started Using TypeScript tutorial](https://xrpl.org/docs/tutorials/get-started/get-started-typescript) on xrpl.org.

## Setup

Install the runtime and development dependencies (`xrpl`, `typescript`, and `@types/node`):

```sh
npm install
```

## Run the Code

**Node.js**

Compile the TypeScript to JavaScript, then run it:

```sh
npx tsc
node ./dist/get-acct-info.js
```

You should see output similar to the following:

```sh

}

Listening for ledger close events...
Ledger #9949269 validated with 0 transactions!
Ledger #9949270 validated with 0 transactions!

Disconnected
```

**Web**

Compile the TypeScript, then open `index.html` in a web browser and wait for the results to appear on the page:

```sh
npx tsc
```

The page loads `xrpl.js` through an import map and runs the compiled `dist/browser.js`. You should see output similar to the following:

```text
