Wt: an introduction

Wt (pronounced as witty) is a C++ library for developing

web applications.

The API is widget-centric

and uses well-tested patterns of

desktop GUI development tailored to the web. To the developer, it

offers abstraction of web-specific implementation details, including

client-server protocols, event handling, graphics support, graceful

degradation (or progressive enhancement), and URL handling.

Unlike many page-based frameworks, Wt was designed for creating

stateful applications that are at the same time highly interactive

(leveraging techinques such as WebSockets and Ajax to their fullest)

and accessible (supporting plain HTML browsers), using automatic

graceful degradation or progressive enhancement

. Things that

are natural and simple with Wt would require an impractical amount of

effort otherwise: switching widgets using animations, while being

perfectly indexed by search robots with clean URLs, or having a

persistent chat widget open throughout, that even works in legacy

browsers like Microsoft Internet Explorer 6.

The library comes with an application server that acts as a

stand-alone Http(s)/WebSocket server or integrates through FastCGI

with other web servers.
