Initialisation

By default FacebookProvider is loading facebook script immediately after render (you are able to use it with SSR). If you want to download facebook script only when facebook component is rendered you need to add parameter lazy to FacebookProvider. Use only one instance of the FacebookProvider on your page.

Usage

Like button

import { FacebookProvider, Like } from 'react-facebook';

export default function LikeExample() {
  return (
    <FacebookProvider appId="123456789">
      <Like href="http://www.facebook.com" colorScheme="dark" showFaces share />
    </FacebookProvider>
  );
}

useShare

import { FacebookProvider, useShare } from 'react-facebook';

export default function ShareExample() {
  const { share, isLoading, error } = useShare();

  async function handleShare() {
    await share({
      href: 'http://www.facebook.com',
    });
  }

  return (
    <button type="button" disabled={isLoading} onClick={handleShare}>Share</button>
  );
}

Share button

You can use predefined button

import { FacebookProvider, ShareButton } from 'react-facebook';

export default function ShareButtonExample() {
  return (
    <FacebookProvider appId="123456789">
      <ShareButton href="http://www.facebook.com" className="my-classname">
        Share
      </ShareButton>
    </FacebookProvider>
  );
}

Comments

import { FacebookProvider, Comments } from 'react-facebook';

export default function CommentsExample() {
  return (
    <FacebookProvider appId="123456789">
      <Comments href="http://www.facebook.com" />
    </FacebookProvider>
  );
}

If comments do not work and you are seeing this error in the browser console:

Refused to display 'https://www.facebook.com/v3.1/plugins/comments.php?blahblahblah' in a frame because it set 'X-Frame-Options' to 'DENY'.

Possible reasons:

1. If the site visitor is from the EU region, the visitor needs to be both:
   • Logged in to Facebook.
   • Have third-party cookies enabled in FB privacy settings.
2. User is using a browser that is blocking third party cookies by default (for example Safari and Firefox).

It is not a bug in this library, there is no way around it.

Comments count

import { FacebookProvider, CommentsCount } from 'react-facebook';

export default function CommentsCountExample() {
  return (
    <FacebookProvider appId="123456789">
      <CommentsCount href="http://www.facebook.com" />
    </FacebookProvider>
  );
}

useLogin

import { FacebookProvider, useLogin } from 'react-facebook';

export default function LoginExample() {
  const { login, status, isLoading, error} = useLogin();
  
  async function handleLogin() {
    try {
      const response = await login({
        scope: 'email',
      });

      console.log(response.status);
    } catch (error: any) {
      console.log(error.message);
    }
  }

  return (
    <button onClick={handleLogin} disabled={isLoading}>
      Login via Facebook
    </button>
  );
}

    const response = await api.login();

User Profile

This component will not sign user. You need to do that with another component. Default scope: 'id', 'first_name', 'last_name', 'middle_name', 'name', 'name_format', 'picture', 'short_name', 'email'. If profile is undefined login status !== LoginStatus.CONNECTED

import { FacebookProvider, useProfile } from 'react-facebook';

export default function UseProfileExample() {
  const { profile, isLoading, error } = useProfile(['id', 'name']);

  return (
    <div>
      {profile?.name} has id: {profile?.id}
    </div>    
  );
}
