Tuleap front end can be divided in two worlds
- Mostly static pages that are rendered server side using mustache templating (with some vanilla JS for simple interactions).
- Rich, dynamic, pages that are rendered client side using Vuejs.
Front end build system is based on Vite with some historic parts using Webpack.
Tuleap uses its own design system, how to use it and the available components can be seen on design-system.tuleap.net.
Historically you will also find:
- AngularJS 1.X code.
- JQuery code.
- Prototype / Scriptaculous code.
- Good old php3&4/mysql scripts where DB, HTML and JS are mixed.
Those are usages and technologies of the past and must be forgotten. New contributions should not be based on them.
