Step-by-Step Guide to Implement Login with Facebook

Before we dive into the code, we need to create a Facebook App to get the required credentials. Follow the below steps to create a Facebook App:

1. Go to the Facebook Developer Portal and login to your account.
2. Click the ‘Create App’ button and select the ‘For everything else’ option.
3. Enter your app name and email address and click ‘Create App ID’.
4. Select the ‘Facebook Login’ option from the left-hand side menu and click ‘Set Up’.
5. Choose ‘Web’ as the platform and enter your website URL.
6. Click the ‘Add Platform’ option and select the ‘Website’ option.
7. Enter your website domain under the ‘Site URL’ section and click ‘Save Changes’.

Once you have created your Facebook App, you need to integrate the Login with Facebook feature into your application. Follow the below steps to implement Login with Facebook:

Step 1: Add Facebook SDK to your Project

To get started, you need to add the Facebook SDK to your project. You can either download it from the Facebook Developer Portal or add it as a dependency in your project using any package manager.

Example (Dependency for npm)

npm install react-facebook-login

Step 2: Initialize Facebook App ID

After adding the Facebook SDK to your project, you need to initialize Facebook App ID to connect with your Facebook App.

Example

import FacebookLogin from 'react-facebook-login';

<FacebookLogin
  appId="your_app_id"
  autoLoad={false}
  fields="name,email,picture"
/>

Step 3: Handle Facebook Login Response

After initializing Facebook App ID, you need to handle the login response to determine if the login was successful or not. You can use the data received in the response to authenticate the user and redirect them to the desired page.

Example

<FacebookLogin
  appId="your_app_id"
  autoLoad={false}
  fields="name,email,picture"
  callback={responseFacebook}
/>

const responseFacebook = (response) => {
  console.log(response);
  // Use data received in the response to authenticate user and redirect to the page
}

Step 4: Display User Information

Once the user is logged in, you can display their name, profile picture, and email address on your website or application.

Example

const responseFacebook = (response) => {
  console.log(response);
  const { name, email, picture } = response;
  setUser({
    name,
    email,
    picture: picture.data.url
  });
};

return (
  <div>
    {user.name && <p>{user.name}</p>}
    {user.email && <p>{user.email}</p>}
    {user.picture && <img src={user.picture} />}
  </div>
);
