# Server-Sent Events Stream

Server-Sent Events Stream can send Server-Sent Events using Node.js.

## How to install

$ npm install sse_stream

```

## How to use

Server side

```js

var http = require("http");

var SSEStream = require("sse_stream");

var fs = require("fs");

http.createServer(function(req, res){

  if (req.headers["accept"] === "text/event-stream") {

    var sse_stream = new SSEStream();

    var exec = require('child_process').exec;

    var child = exec("tail -f test.log");

    res.writeHead(200, {

    'Content-type': 'text/event-stream',

    'Cache-Control': 'no-cache',

    'Connection': 'keep-alive'

    });

    child.stdout.pipe(sse_stream).pipe(res);

    sse_stream.on("end", function() {

      res.end();

    });

    readStream.on("end", function() {

      res.removeAllListeners();

    });

    sse_stream.on("error", function(error) {

      console.error("error " + error);

    });

    readStream.on("error", function(error) {

      console.error("error " + error);

    });

  } else {

    fs.createReadStream("index.html").pipe(res);

  }

}).listen(8080);

          $('html, body').animate({
