Small is big. Introducing PrestoUI, a 35KB alternative to React Native
We wanted a UI builder for our SDK, but the usual suspects, React Native and NativeScript, were not suitable. Their HelloWorld apps were ~7MB each. Too big. This is why we started building PrestoUI. Since our main product is an SDK inside other apps, we have size constraints(<150kB) and we also wanted the ability to dynamically update the UI so that we didn’t need SDK updates for every small change.
Another interesting feature that emerged was that Android’s UI language turned out to be the right balance of simplicity and generic nature for cross platform — iOS and Web.
While designing the user interfaces we found that Android’s UI language was surprisingly simple and powerful enough for cross platform views — Android, iOS, Progressive Web. We think this is because Android was designed to support varied device sizes from the start. This also enabled Android developers to start on PrestoUI with ease. Also the resultant web and mobile web UI has small footprint and low page load time.
Support For Types
Sketch Design to Code generation
To enable designers to prototype and to directly generate production UI, we also developed a Sketch plugin with hot reload. This eliminates the designer-to-developer handover process and creates pixel perfect implementation by default — yay, happy designers!
If you are looking for a lightweight yet powerful cross platform library to create apps give PrestoUI a spin. Everything you need to get started is in PrestoUI quick start.
