React Native FB Login

React Native FB Login is fully IOS and Android compatible component without using any Facebook Native/Web SDK, allowing for Facebook Login integration in React Native apps and it also supports responses like username which deprecated by Facebook. To use this component developers don't need to install any native sdks also don't need to import or link any sdks in IOS and Android from Facebook. This component is fully compatible and tested with all React Native versions no more errors like other components and it is very easy to use.

We use direct Facebook Graph API to prevent importing/linking Native SDK steps from Facebook.

🚨Update: Fresh v1.0.5 with many new features is ready 📹 https://bit.ly/33HxQ2J, please upgrade now if you haven't via npm or yarn

IOS/Android Preview

Setup Facebook Login App

You will need to create Facebook Login App to use with this component and +add Click to see Link in your redirect-url Facebook Login App Settings in Valid OAuth Redirect URIs input field, this link is required in Facebook Login App as it will get use when redirection will occurs when user will logged-in from your application, also you can control this redirect-url from this component as a prop redirectUrl='YOUR_REDIRECT_URL' for server-side scriptings like PHP, JSP, nodeJS to store user information like token,first_name,last_name when user will logged-in but it's optional. If you have created already Facebook Login App then you can skip all steps except adding redirect-url in your Facebook Login App Settings in Valid OAuth Redirect URIs input field. When everything is done you just need to grab clientId and secretKey from your Facebook Login App, this component will need these props later.

Note: When you create new Facebook Login App by default App mode always set to development and this component works fine with it, but when you are ready to upload your React Native app to the appstores do not forget to submit your Facebook Login App for reviewing to change it's status from development to public mode.
