RxEventSource

API Reference

Background

Helper function to create an RxJS observable from EventSource.

Installation

NPM

npm install rx-event-source rxjs@7

or

yarn add rx-event-source rxjs@7

Usage

Basic usage

See available options.

import { eventSource$ } from 'rx-event-source';

const options = {
  // ...
};

eventSource$('/api/v1/sse', { withCredentials: false }, options).subscribe((data) => {
  console.log(data);
});

Handling streaming errors

The streaming error can be emitted as a message with specific data format and then handled manually by throwing an error.

import { eventSource$ } from 'rx-event-source';

const options = {
  // ...
};

function isError(data) {
  // ...
}

eventSource$('/api/v1/sse', { withCredentials: false }, options).pipe(
  map((data) => {
    if (isError(data)) {
      throw new Error(data.error);
    }
    return data;
  })
).subscribe((data) => {
  console.log(data);
});
