Declarative UIs in a functional language

AUDIENCE

Functional programmers interested in graphical UIs.

OBJECTIVES

- How our UI libraries evolved over time.

- How to write maintainable UI code.

DESCRIPTION

We will explore how apps can be written in a functional language, using three components: a declarative view, an update function, and a model without business logic. Many problems such as background tasks, efficient updates, and composition will be addressed. 

This talk is based on a production library developed based on a decade of learnings. More than 100 internal apps benefit from it.
