<h1>FTXUI WebAssembly Example </h1>
|

<p>
|
|
<a href="https://github.com/ArthurSonzogni/FTXUI">FTXUI</a> is a single
|
|
C++ library for terminal user interface.

|
|
On this page, you can try all the examples contained in: <a
|
|
href="https://github.com/ArthurSonzogni/FTXUI/tree/master/examples">./example/</a>
|
|
Those are compiled using WebAssembly.
