In plain words
CalDOM is a JavaScript UI library designed for developers who want a lightweight, agnostic approach to building reactive interfaces. It emphasizes minimalism and works independently of larger frameworks, making it suitable for projects where developers need flexibility without heavy dependencies. The library focuses on reactive functionality, allowing UIs to automatically update when data changes. Launched in 2021, CalDOM serves as an alternative for those seeking a straightforward, framework-agnostic solution for interactive web development.

From the sources
An agnostic, reactive & minimalist (3kb) JavaScript UI library with direct access to native DOM. View benchmark results against Vanilla JS, Vue JS, React JS, jQuery & more. Instead of pulling you into a library-specific magical world, CalDOM let you fully access the DOM directly while keeping the reactivity . So you could take full advantage of native APIs & mix it with other libraries to gain superior performance & flexibility in the development process. Zero tooling, zero dependencies, zero new syntax, just pure JS. This was a lightweight jQuery alternative I made myself years ago & kept on improving it slowly. Also, I wanted to stay close to the native DOM API & vanilla JavaScript.…from caldom.org

Yes, another reactive UI framework for JavaScript. Bear with me, please... :-) I 'invented' the concept for this back in 2011, and it was used (as a proprietary lib) in various startups. Even though many similar open source libs have been released since, and boy have I tried a lot of them, none have been able to capture the elegance and DX of what we had back then. I might be biased though. :-) So I started creating a cleaned-up, modern, TypeScript, open source implementation for the concept about five years ago. After many iterations, working on the project on and off, I'm finally happy…
