Package Exports

@react-native-module/randombytes
@react-native-module/randombytes/lib/cjs/src/index.js
@react-native-module/randombytes/lib/es/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@react-native-module/randombytes) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-native-module/randombytes

Usage

import { randomBytes } from "@react-native-module/randombytes";

// synchronous API
const rand = randomBytes(4);

// asynchronous API
// uses iOS-side SecRandomCopyBytes
randomBytes(4, (err, bytes) => {
  // bytes is a Buffer object
  console.log(bytes.toString("hex"));
});

Installation

A typical workflow:

npm install --save @react-native-module/randombytes

yarn add @react-native-module/randombytes

Automatic - Android / iOS (recommended)

react-native link

Manual

If Automatic installation failed you, dry your tears and read on.

`iOS`

Drag RNRandomBytes.xcodeproj from node_modules/react-native-randombytes into your XCode project.
Click on the project in XCode, go to Build Phases, then Link Binary With Libraries and add libRNRandomBytes.a

Confused? See an example with screenshots here

`Android`

Update Gradle Settings

// file: android/settings.gradle
...

include ':randombytes', ':app'
project(':randombytes').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-randombytes/android')

Update Gradle Build

// file: android/app/build.gradle
...

dependencies {
    ...
    compile project(':randombytes')
}

...
import com.bitgo.randombytes.RandomBytesPackage // import

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {

    private ReactInstanceManager mReactInstanceManager;
    private ReactRootView mReactRootView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mReactRootView = new ReactRootView(this);
        mReactInstanceManager = ReactInstanceManager.builder()
                .setApplication(getApplication())
                .setBundleAssetName("index.android.bundle")
                .setJSMainModuleName("index.android")
                .addPackage(new MainReactPackage())
                .addPackage(new RandomBytesPackage()) // register package here
                .setUseDeveloperSupport(BuildConfig.DEBUG)
                .setInitialLifecycleState(LifecycleState.RESUMED)
                .build();
        mReactRootView.startReactApplication(mReactInstanceManager, "AwesomeProject", null);
        setContentView(mReactRootView);
    }
...

`Windows`

react-native link react-native-randombytes

Depending on your project versions and the state of RN-Windows this may not always work. If it does not, a manual installation guide can be found here:
