### Using xrpl.js from a CDN

- jsdelivr `<script src="https://cdn.jsdelivr.net/npm/xrpl@2.3.0/build/xrpl-latest-min.js"></script>`

Ensure that the full path is provided so the browser can find the sourcemaps.

### Using xrpl.js with React Native

If you want to use `xrpl.js` with React Native you will need to install polyfills for core NodeJS modules.

1. Install dependencies (you can use `yarn` as well):

   ```shell
   npm install xrpl \
       fast-text-encoding \
       react-native-get-random-values
   ```

2. After that, run the following commands:

   ```shell
   # compile `react-native-get-random-values` pods see https://www.npmjs.com/package/react-native-get-random-values#installation
   npx pod-install
   ```
   
3. Create `polyfills.js` and add

```javascript
// Required for TextEncoder/TextDecoder
import 'fast-text-encoding'
// Required for `crypto.getRandomValues`
import 'react-native-get-random-values'
```

4. Import `polyfills` in index file your project (it must be the first line):

```javascript
import './polyfills'
...
```

> [!NOTE]
> The following is currently broken due to https://github.com/denoland/deno/issues/20516.
> Once that is fixed there could be other issues as well.

```javascript
import xrpl from 'https://dev.jspm.io/npm:xrpl';

(async () => {
  const api = new (xrpl as any).Client('wss://s.altnet.rippletest.net:51233');
  const address = 'rH8NxV12EuV...khfJ5uw9kT';

  api.connect().then(() => {
    api.getBalances(address).then((balances: any) => {
      console.log(JSON.stringify(balances, null, 2));
    });
  });
})();
```
