+# react-native-create-guid
+
+Minimal library to create Guids in React Native. It uses the native implementations to generate one and send it over to JS.
+
+## Why?
+
+When faced with the problem of generating a GUID in React Native, I found that there were no current good solutions. Relying on `Math.random` didn't seem like a good idea, and the other alternatives found like [react-native-uuid](https://www.npmjs.com/package/react-native-uuid) that are just ports of node.js libraries (needed to install other libraries buffer).
+
+Since native platforms already have ways to create GUIDs that are useful, creating a simple native library would be enough to use them in React-Native.
+
+## Getting started
+
+`$ npm install react-native-create-guid --save`
+
+### Mostly automatic installation
+
+**RN < 0.60:**
+
+`$ react-native link react-native-create-guid`
+
+**RN >= 0.60:**
+
+`$ cd ios && pod install`
+
+### Manual installation
+
+#### iOS
+
+1. In XCode, in the project navigator, right click `Libraries` ➜ `Add Files to [your project's name]`
+2. Go to `node_modules` ➜ `react-native-create-guid` and add `CreateGuid.xcodeproj`
+3. In XCode, in the project navigator, select your project. Add `libCreateGuid.a` to your project's `Build Phases` ➜ `Link Binary With Libraries`
+4. Run your project (`Cmd+R`)<
+
+#### Android
+
+1. Open up `android/app/src/main/java/[...]/MainApplication.java`
+
+- Add `import com.reactnative.createguid.CreateGuidPackage;` to the imports at the top of the file
+- Add `new CreateGuidPackage()` to the list returned by the `getPackages()` method
+
+2. Append the following lines to `android/settings.gradle`:
+   ```
+   include ':react-native-create-guid'
+   project(':react-native-create-guid').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-create-guid/android')
+   ```
+3. Insert the following lines inside the dependencies block in `android/app/build.gradle`:
+   ```
+     compile project(':react-native-create-guid')
+   ```
+
+## Usage
+
+Check the example under `example` folder for it's usage.
+
+```javascript
+import { createGuid } from "react-native-create-guid";
+
+// in an async function;
+const guid = await createGuid();
+
+// using promises
+createGuid().then(guid => console.log(guid));
+```

+README
+======
+
+If you want to publish the lib as a maven dependency, follow these steps before publishing a new version to npm:
+
+1. Be sure to have the Android [SDK](https://developer.android.com/studio/index.html) and [NDK](https://developer.android.com/ndk/guides/index.html) installed
+2. Be sure to have a `local.properties` file in this folder that points to the Android SDK and NDK
+```
+ndk.dir=/Users/{username}/Library/Android/sdk/ndk-bundle
+sdk.dir=/Users/{username}/Library/Android/sdk
+```
+3. Delete the `maven` folder
+4. Run `./gradlew installArchives`
+5. Verify that latest set of generated files is in the maven folder with the correct version number
