[](https://nodei.co/npm/eventsource/)
[](https://nodei.co/npm/eventsource/)
This library is a pure JavaScript implementation of the [EventSource](http://www.w3.org/TR/eventsource/) client. The API aims to be W3C compatible.
You can use it with Node.js or as a browser polyfill for
[browsers that don't have native `EventSource` support](http://caniuse.com/#search=eventsource).
## Install
npm install eventsource
## Example
npm install
node ./example/sse-server.js
node ./example/sse-client.js # Node.js client
open http://localhost:8080 # Browser client - both native and polyfill
curl http://localhost:8080/sse # Enjoy the simplicity of SSE)
## Browser Polyfill
Just add `example/eventsource-polyfill.js` file to your web page:
```html
```
Now you will have two global constructors:
```javascript
window.EventSourcePolyfill
window.EventSource // Unchanged if browser has defined it. Otherwise, same as window.EventSourcePolyfill
```
If you're using [webpack](https://webpack.github.io/) or [browserify](http://browserify.org/)
you can of course build your own. (The `example/eventsource-polyfill.js` is built with webpack).
## Extensions to the W3C API
### Setting HTTP request headers
You can define custom HTTP headers for the initial HTTP request. This can be useful for e.g. sending cookies
or to specify an initial `Last-Event-ID` value.
HTTP headers are defined by assigning a `headers` attribute to the optional `eventSourceInitDict` argument:
```javascript
var eventSourceInitDict = {headers: {'Cookie': 'test=test'}};
var es = new EventSource(url, eventSourceInitDict);
```
### Allow unauthorized HTTPS requests
By default, https requests that cannot be authorized will cause connection to fail and an exception
to be emitted. You can override this behaviour:
```javascript
var eventSourceInitDict = {rejectUnauthorized: false};
var es = new EventSource(url, eventSourceInitDict);
```
Note that for Node.js < v0.10.x this option has no effect - unauthorized HTTPS requests are *always* allowed.
### HTTP status code on error events
Unauthorized and redirect error status codes (for example 401, 403, 301, 307) are available in the `status` property in the error event.
```javascript
es.onerror = function (err) {
if (err) {
if (err.status === 401 || err.status === 403) {
console.log('not authorized');
}
}
};
```
### HTTP/HTTPS proxy
You can define a `proxy` option for the HTTP request to be used. This is typically useful if you are behind a corporate firewall.
```javascript
var es = new EventSource(url, { proxy: 'http://your.proxy.com' });
```

// a transform stream is a readable/writable stream where you do
// something with the data. Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored. (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation. For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes. When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up. When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer. When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks. If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk. However,
// a pathological inflate type of transform can cause excessive buffering
// here. For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output. In this case, you could write a very small
// amount of input, and end up with a very large amount of output. In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform. A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
