StompJs v5+, RxStomp: Polyfills

1 minute read

This guide covers critical dependencies and polyfills for version 5+ of @stomp/stompjs; which is internally used by @stomp/rx-stomp as well.

In NodeJS

There are two alternate libraries websocket and ws which have been reported to work.

Using import syntax

import websocket from 'websocket';

Object.assign(global, { WebSocket: websocket.w3cwebsocket });

Instead of websocket lib ws has also been reported to work. See: stompjs/issues/28.
Add ws npm module:
```
$ npm install ws
```

Require the module and expose it through global

import { WebSocket } from 'ws';

Object.assign(global, { WebSocket });

React Native makes it deceptive. When an application is executed in debug mode, it works, as it is executed on an actual browser where TextEncoder/TextDecoder is available. However, when executed in production mode, it fails as TextEncoder/TextDecoder is not available.
Please install text-encoding
```
$ npm install text-encoding
```

Add the following to your index.js or App.js:

import * as encoding from 'text-encoding';

There are additional issues with React Native in some device/version combinations. Please see: React Native - Additional Notes
