With the help of WebSocket technology, we can send message from server-to-clients or from client-to-server in a **full-duplex communication channels over a single TCP connection.**
|

|
|
|

We use the **WebSocket client** to populate asynchronously an _"area chart"_ with real time datas from ESP regarding the **total size of heap memory** and size of **max contiguous block of memory**.

Off course, on the ESP MCU we will run also a WebSocket server together to the web server.

I've used this library [arduinoWebSockets](https://github.com/Links2004/arduinoWebSockets), so it is needed to compile, but you can choose which you prefer.

This example will run only if an internet connection is available because [Highcharts](https://www.highcharts.com/) Javascript resources is necessary

(to run offline in AP mode, you can download all the used js files, put it in the flash memory (better if gzipped to speed-up page loading) and edit the [index.htm](https://github.com/cotestatnt/esp-fs-webserver/blob/main/examples/highcharts/data/index.htm))
