@nativescript/facebook

Installation

npm install @nativescript/facebook

Prerequisites

Android

Before you can run the project, follow the Getting Started Guide for Facebook Android SDK to set up a Facebook app. You can skip the build.gradle changes since that's taken care of by the rnpm link step above, but make sure you follow the rest of the steps such as updating strings.xml and AndroidManifest.xml.

iOS

Follow step 3 in the Getting Started Guide for Facebook SDK for iOS.

Usage

First of all, you should initialize the LoginManager by calling the init method.

import { LoginManager } from '@nativescript/facebook';

LoginManager.init()

Then to log the user in, use the logInWithPermissions method. You can also use the Login Manager with custom UI to perform Login.

import { LoginManager, AccessToken } from '@nativescript/facebook';

try {
	const result = await LoginManager.logInWithPermissions(['public_profile']); // LoginResult
	const accessToken = AccessToken.currentAccessToken();
} catch (e) {}

To log the user out, call the logOut method.

LoginManager.logOut()
