react-native-random-values-jsi-helper

React Native polyfill for crypto.getRandomValues. Used in libraries like uuid.

Installation

React Native 0.71.0 or higher:

yarn add react-native-random-values-jsi-helper
npx pod-install

React Native < 0.71:

yarn add [email protected]
npx pod-install

Usage

Import react-native-random-values-jsi-helper in your index.js file.

//index.js
import "react-native-random-values-jsi-helper";

You can now use the uuid package in your React Native app.

Performance

This module is written in C++ JSI.

Basically there is no over the bridge traffic overhead and no serialization/deserialization since the random arrays are generated on native side.

react-native-random-values-jsi-helper's Issues

[RN 0.71.0 build error] Expected directory '.../node_modules/react-native/android' to contain exactly one file, however, it contains no files

Hey there, thanks a lot for all the work on this 🙏

I came across the following when I updated a project to 0.71.0 when building android:

* Where:
Build file '.../node_modules/react-native-random-values-jsi-helper/android/build.gradle' line: 172

* What went wrong:
A problem occurred evaluating project ':react-native-random-values-jsi-helper'.
> Expected directory '.../node_modules/react-native/android' to contain exactly one file, however, it contains no files.

seems to be related to react-native-community/discussions-and-proposals#508

also, they added this to react-native/android/README.md

I tried to fix it, but then came across another issue related to CMakeLists.txt,
[CMake Error: The following variables are used in this project, but they are set to NOTFOUND] for REACT_NATIVE_JNI_LIB and JSI_LIB

probably was trying the wrong thing. 😄
