# lws minimal secure streams server
|
|
|
|
The application sets up a tls + ws server on https://localhost:7681
|
|
|
|
It does it using Secure Streams... information about how the server should
|
|
operate is held in JSON policy in main.c
|
|
|
|
Visiting the server in a modern browser will fetch some html + JS, the JS will
|
|
create a ws link back to the server and the server will spam an incrementing
|
|
number that is displayed in the browser every 100ms.
|
|
|
|
The app also has a SS client that works, but it's disabled by default since
|
|
we're interested in server.
|
|
|
|
## build
|
|
|
|
```
|
|
$ cmake . && make
|
|
```
