This is an example library that explains how anyone can build jsi modules from scratch in React Native. This code is written as a support project for my blog.

npm install react-native-simple-jsi

You must have Android NDK and CMake installed on android to build the library.

The following methods are implemented.

The relevant code is present in cpp/example.cpp file.

    helloWorld():string;

    multiplyWithCallback(x:number,y:number,callback:(z:number) => void):void
    
    multiply(x:number,y:number):number

The relevant code on android is in android/cpp-adapter.cpp and ios/SimpleJsi.mm on iOS.

    getDeviceName():string
    
    setItem(key:string,value:string):boolean

    getItem(key:string):string

import simpleJsiModule from "react-native-jsi-template";

simpleJsiModule.helloWorld() // returns helloworld.

Run the example app for more.
