react-native-native-log

A React Native log function that under the hood calls NSLog() on iOS and Log.i() on Android.

A potential use case for this library is to be able to read logs with an E2E UI testing tool like Appium.

Installation

npm install react-native-native-log

Usage

import NativeLog from "react-native-native-log";

// ...

NativeLog.log('hello world'); // hello world
// or
NativeLog.logWithTag('my-tag', 'hello world'); // [my-tag] hello world

Example app

To get started with the project, run yarn bootstrap in the root directory to install the required dependencies for each package:

yarn bootstrap

Android

To run the example app on Android:
