express-stream-sse

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);

});

app.listen(process.env.PORT || 4000);

Then on the client side you can :

var source = new EventSource('/events');

};
