Purescript Purview

Overview

Purview offers an innovative proof-of-concept UI library that leverages the principles of incremental lambda calculus to streamline DOM updates without relying on a virtual DOM. By focusing on a rendering function that’s computable and responds dynamically to model changes, Purview aims to simplify the way developers handle UI updates, resulting in more efficient applications. This approach not only enhances performance but also offers a fresh perspective on how we can structure front-end development.

The library provides a flexible framework that encourages developers to craft various APIs tailored to their specific needs. With an example API for guidance, users can quickly adapt and explore the potential of Purview, whether they’re working on personal projects or larger applications.

Features

• Incremental Rendering: Utilizes incremental lambda calculus to propagate model changes to the DOM without a diff algorithm, enhancing rendering efficiency.
• Static DOM Structure: Allows certain parts of the DOM to be defined as static through types, reducing unnecessary re-renders and improving performance.
• Unopinionated Toolkit: Offers a flexible foundation that developers can use to create and tailor their own APIs, promoting creativity and innovation in UI design.
• Example API: Comes with a reference example that provides practical application of the concepts, helping users to get started quickly.
• Focus on Computability: Ensures the rendering functions are not just executable, but also provide insight into how views change with model alterations, fostering better control over UI logic.
• Reduced Complexity: Strives to simplify front-end development by eliminating the complications introduced by a virtual DOM approach, making it easier to manage application state.
• Active Community: Being part of the PureScript ecosystem, users can tap into an engaging community that shares insights and improvements related to the library.
