Facebook App Integration

Implementing Facebook OAuth authentication

Integrating “Login with Facebook” into a notes application involves understanding the interaction between various components and setting up the necessary configuration for OAuth authentication. This lesson will guide us through the process, covering everything from setting up your Facebook app to managing sessions post-authentication.

To integrate Facebook OAuth into the notes application, we’ll perform the following steps:

1. Integrate the oauth2 package: We will incorporate the oauth2 package into the application. We will add the package as a dependency and initialize it with the credentials obtained from Facebook.

2. Table for the oauth2 user info: We will introduce a new model/entity to store information about the user received from the OAuth provider (in our case, Facebook).

3. Handling the callback: We will create a route in the app to receive the callback from Facebook.

4. Authentication mechanism: We will implement an authentication mechanism using OAuth 2.0 provided by Facebook. This will involve redirecting users to Facebook for login and handling the callback to receive an access token.

In the application, we need to install the oauth2 package.
