CSS in JS Benchmarks

for React Native

Results

See RESULTS.md for the benchmark results.

Technique

• Big table with random data and dynamic background color opacity
• Multiple implementations for each lib with small variations, e.g. using inline styles or not
• Multiple rerenders are executed per test and the result is their average render time

Libs

• fela-native
• glamorous-native
• react-native
• styled-components

Know any other? Please open an issue or, preferrably, a pull request :)

Inspiration

The idea and some code pieces are heavily inspired by A-gambit/CSS-IN-JS-Benchmarks, which benchmarks were made for React Web.

How to run

• Run git clone [email protected]:brunolemos/react-native-css-in-js-benchmarks.git

Automatically

Detox will run all benchmarks and show the results at the end.
