Deku vs Riot: What are the differences?
Developers describe Deku as "Functional view library for building UI components as an alternative to React". A library for creating UI components using virtual DOM as an alternative to React. Deku has a smaller footprint (~10kb), a functional API, and doesn't support legacy browsers. On the other hand, Riot is detailed as "A React-like user interface micro-library". Riot brings custom tags to all browsers. Think React + Polymer but with enjoyable syntax and a small learning curve.
Deku and Riot are both open source tools. It seems that Riot with 13.7K GitHub stars and 1.02K forks on GitHub has more adoption than Deku with 3.41K GitHub stars and 167 GitHub forks.
