+JavaScript and TypeScript clients for SignalR for ASP.NET Core and Azure SignalR Service
+
+## Installation
+
+```bash
+npm install @microsoft/signalr
+# or
+yarn add @microsoft/signalr
+```
+
+To try previews of the next version, use the `next` tag on NPM:
+
+```bash
+npm install @microsoft/signalr@next
+# or
+yarn add @microsoft/signalr@next
+```
+
+## Usage
+
+See the [SignalR Documentation](https://learn.microsoft.com/aspnet/core/signalr) at learn.microsoft.com for documentation on the latest release. [API Reference Documentation](https://learn.microsoft.com/javascript/api/%40aspnet/signalr/?view=signalr-js-latest) is also available on learn.microsoft.com.
+
+For documentation on using this client with Azure SignalR Service and Azure Functions, see the [SignalR Service serverless developer guide](https://learn.microsoft.com/azure/azure-signalr/signalr-concept-serverless-development-config).
+
+### Browser
+
+To use the client in a browser, copy `*.js` files from the `dist/browser` folder to your script folder include on your page using the `
+```
+
+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 the connection to fail and an exception
+to be emitted. You can override this behaviour, along with other https options:
+
+```javascript
+var eventSourceInitDict = {https: {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.
