react-native-fetch-sse v0.1.0

react-native-fetch-sse

consume text-stream response with standard fetch, works with any custom server and OpenAI API.

• Implemented using native fetch(), so you can pass headers, different Http methods, AbortController, etc.
• minimal implementation, great for web only projects also
• works on React Native / Web
• included all polyfills (only for Native, web doesn't need them)

Installation

npm install react-native-fetch-sse

Usage

import { fetchSSE } from 'react-native-fetch-sse';

// in a onPress() handler

const onPress = async () => {
  fetchSSE(
    '/chat-stream',
    {
      method: 'POST',
      headers: {
        Authorization: 'my-token',
      },
    },
    {
      onStart() {
        console.log('it starts');
      },

      onMessage(data) {
        console.log('receiving event', data);
      },

      onError(error, { status, statusText }) {
        console.log('error', error);
        console.log('http status code', status);
        console.log('http statusText', statusText);
      },

      onEnd() {
        console.log('the stream finished');
      },

      // if you are streaming done JSON,
      // set this to true will receive the object instead of a string
      shouldParseJsonWhenOnMsg: true,
    },
  );
};
