Example

This example shows how to use Websockets and Erlang Web server using binary Erlang External Term Format. All messages are exchanged between client/server using a binary (end-to-end) [Javascript implementation of the Erlang External Term format] (https://github.com/saleyn/erlb.js).

Getting

$ git clone https://github.com/saleyn/erws_example.git

Building

Initial build:

$ make deps

Successive build:

$ make

Running

$ make run

Open a Web browser (tested with Chrome and Firefox) and point to your server's address, port 40000. The click on the link "Open a websocket demo" and you should see a popup window that looks like this:

Clicking on the 'Ping' hyperlink will initiate a message sent back and forth between client browser and server 10000 times.

The green and purple time-series represent random values sent from the server in the form {TickerX, Value::integer(), Dummy::binary()} where TickerX is either ticker1 or ticker2, Value is a random value used to plot in the corresponding time-series, and the Dummy is dummy payload of size 1Kb.

The red time-series is the messages per secord rate of ticker1 and ticker2 respectively. Yellow time-series is the total inbound messages per second rate, and orange time-series is the messages per second rate of incoming replies to the ping requests initiated by user.
