## Introduction
[*WebSocket*](https://en.wikipedia.org/wiki/WebSocket) is a computer communications protocol, providing full-duplex and bi-directionnal communication channels over a single TCP connection. *IXWebSocket* is a C++ library for client and server Websocket communication, and for client HTTP communication. The code is derived from [easywsclient](https://github.com/dhbaird/easywsclient) and from the [Satori C SDK](https://github.com/satori-com/satori-rtm-sdk-c). It has been tested on the following platforms.

## Examples
The [*ws*](https://github.com/machinezone/IXWebSocket/tree/master/ws) folder countains many interactive programs for chat, [file transfers](https://github.com/machinezone/IXWebSocket/blob/master/ws/ws_send.cpp), [curl like](https://github.com/machinezone/IXWebSocket/blob/master/ws/ws_http_client.cpp) http clients, demonstrating client and server usage.

## Build
CMakefiles for the library and the examples are available. This library has few dependencies, so it is possible to just add the source files into your project. Otherwise the usual way will suffice.

```
mkdir build # make a build dir so that you can build out of tree.
cd build
cmake ..
make -j
make install # will install to /usr/local on Unix, on macOS it is a good idea to sudo chown -R `whoami`:staff /usr/local
```
Headers and a static library will be installed to the target dir.
A [conan](https://conan.io/) file is available at [conan-IXWebSocket](https://github.com/Zinnion/conan-IXWebSocket).
There is a unittest which can be executed by typing `make test`.
There is a Dockerfile for running some code on Linux. To use docker-compose you must make a docker container first.
```
$ make docker
...
$ docker compose up &
...
$ docker exec -it ixwebsocket_ws_1 bash
app@ca2340eb9106:~$ ws --help
ws is a websocket tool
...
```
Finally you can build and install the `ws command line tool` with Homebrew. The homebrew version might be slightly out of date.
```
brew tap bsergean/IXWebSocket
brew install IXWebSocket
```

## Implementation details
@ -240,31 +134,37 @@ No manual polling to fetch data is required. Data is sent and received instantly
If the remote end (server) breaks the connection, the code will try to perpetually reconnect, by using an exponential backoff strategy, capped at one retry every 10 seconds.
### Large messages
Large frames are broken up into smaller chunks or messages to avoid filling up the os tcp buffers, which is permitted thanks to WebSocket [fragmentation](https://tools.ietf.org/html/rfc6455#section-5.4). Messages up to 1G were sent and received succesfully.
## Limitations
* No utf-8 validation is made when sending TEXT message with sendText()
* There is no text support for sending data, only the binary protocol is supported. Sending json or text over the binary protocol works well.
* Automatic reconnection works at the TCP socket level, and will detect remote end disconnects. However, if the device/computer network become unreachable (by turning off wifi), it is quite hard to reliably and timely detect it at the socket level using `recv` and `send` error codes. [Here](https://stackoverflow.com/questions/14782143/linux-socket-how-to-detect-disconnected-network-in-a-client-program) is a good discussion on the subject. This behavior is consistent with other runtimes such as node.js. One way to detect a disconnected device with low level C code is to do a name resolution with DNS but this can be expensive. Mobile devices have good and reliable API to do that.
* The server code is using select to detect incoming data, and creates one OS thread per connection. This is not as scalable as strategies using epoll or kqueue.

## Examples
1. Bring up a terminal and jump to the examples folder.
2. Compile the example C++ code. `sh build.sh`
3. Install node.js from [here](https://nodejs.org/en/download/).
4. Type `npm install` to install the node.js dependencies. Then `node broadcast-server.js` to run the server.
5. Bring up a second terminal. `./cmd_websocket_chat bob`
6. Bring up a third terminal. `./cmd_websocket_chat bill`
7. Start typing things in any of those terminals. Hopefully you should see your message being received on the other end.
## C++ code organization
Here is a simplistic diagram which explains how the code is structured in term of class/modules.
