The easiest way to test is simple make your AppRegistry point to our example component, like this:

// in your index.ios.js or
import React, { Component } from "react";
import { AppRegistry } from "react-native";
import App from "react-native-ble-manager/example/App"; //<-- simply point to the example js!
Note: The react-native-ble-manager/example directory is only included when cloning the repo, the above import will not work 
if trying to import react-native-ble-manager/example from node_modules
AppRegistry.registerComponent("MyAwesomeApp", () => App);

Or, use the example directly

Library development

  • the library is written in typescript and needs to be built before being used for publication or local development, using the provided npm scripts in package.json.
  • the local example project is configured to work with the locally built version of the library. To be able to run it, you need to build at least once the library so that its outputs listed as entrypoint in package.json (in the dist folder) are properly generated for consumption by the example project:

from the root folder:

npm install
npm run build

if you are modifying the typescript files of the library (in src/) on the fly, you can run npm run watch instead. If you are modifying files from the native counterparts, you'll need to rebuild the whole app for your target environnement (npm run android/ios).
