React Native Size Matters

Abstract

1. Introduction

When developing with react-native, you need to manually adjust your app to look great on a variety of different screen sizes. That's a tedious job. react-native-size-matters provides some simple tooling to make your scaling a whole lot easier. The idea is to develop once on a standard ~5" screen mobile device and then simply apply the provided utils.  You can read more about what led to this library on my blog post, which can be found in this repo or at Medium.

A lightweight, zero-dependencies, React-Native utility belt for scaling the size of your apps UI across different sized devices.

2. Objective

A lightweight, zero-dependencies, React-Native utility belt for scaling the size of your apps UI across different sized devices.
