Convert NodeJS streams to Server-Sent Events express routes (EventSource)

Install

npm i -S express-stream-sse

Usage

 
import express from 'express';
import streamToSSE from 'express-stream-sse';
 
let app = express();
 
app.get('/events', function(req, res) {
 
    var stream = require('./getSampleStream');
 
    return streamToSSE(res, stream);
 
});
