Aussom Lang - Aussom-Script

What It Is

Aussom-Script brings the full Aussom interpreter to the browser. Write your frontend code in Aussom instead of JavaScript. Same language, same OOP design, no context switching between frontend and backend.

Key Features

Zero JavaScript Required. Build entire web pages using Aussom-Script. DOM manipulation, event handling, and UI composition are all done in Aussom.
Bootstrap Component Library. The included aussomBs library wraps Bootstrap 5 components as Aussom classes. Build responsive UIs with BsCard, BsNavbar, BsModal, and 80+ more components.
Syntax Highlighting. The built-in Highlighter module tokenizes and renders Aussom source code with customizable themes directly in the browser.
Single Dependency. Include aussom-script.js in your page and start writing Aussom. No build tools, no bundler, no npm.

Who It Is For

Web developers who want a clean, typed, object-oriented alternative to JavaScript for building browser-based applications.
