How to use

Basic button with styling

import React from 'react';
import ReactDOM from 'react-dom';
import FacebookLogin from 'react-facebook-login';

const responseFacebook = (response) => {
  console.log(response);
}

ReactDOM.render(
  <FacebookLogin
    appId="1088597931155576"
    autoLoad={true}
    fields="name,email,picture"
    onClick={componentClicked}
    callback={responseFacebook} />,
  document.getElementById('demo')
);

Facebook button without styling

If you're providing all your own custom styling, you can use the render prop build. This build doesn't include any CSS or additional code needed to customise the look of the button, and instead leaves that entirely up to you. You can see an example of this in demo/index.js.

To make sure you import the right version, you will need to update your import line:

import FacebookLogin from 'react-facebook-login/dist/facebook-login-render-props'

<FacebookLogin
  appId="1088597931155576"
  autoLoad
  callback={responseFacebook}
  render={renderProps => (
    <button onClick={renderProps.onClick}>This is my custom FB button</button>
  )}
/>

The render function will be passed the following properties for you to use:

• onClick
• isDisabled
• isProcessing
• isSdkLoaded

Custom CSS Class and Icon

By default fontawesome is included, If you don't want to use default fontawesome icons, you can send an element in icon attribute

Fontawesome example:

import React from 'react';
import ReactDOM from 'react-dom';
import FacebookLogin from 'react-facebook-login';

const responseFacebook = (response) => {
  console.log(response);
}

ReactDOM.render(
  <FacebookLogin
    appId="1088597931155576"
    autoLoad={true}
    fields="name,email,picture"
    callback={responseFacebook}
    cssClass="my-facebook-button-class"
    icon="fa-facebook"
  />,
  document.getElementById('demo')
);

Custom element example:

import React from 'react';
import ReactDOM from 'react-dom';
import FacebookLogin from 'react-facebook-login';
import TiSocialFacebookCircular from 'react-icons/lib/ti/social-facebook-circular';

const responseFacebook = (response) => {
  console.log(response);
}

ReactDOM.render(
  <FacebookLogin
    appId="1088597931155576"
    autoLoad={true}
    fields="name,email,picture"
    callback={responseFacebook}
    cssClass="my-facebook-button-class"
    icon={<TiSocialFacebookCircular />}
  />,
  document.getElementById('demo')
);

Custom permission

By default the component, request only 'public_profile' permission, you can change if you send 'scope', that is a string comma separated attribute.

see https://developers.facebook.com/docs/facebook-login/permissions for permissions list

  import React from 'react';
  import FacebookLogin from 'react-facebook-login';

  class MyComponent extends React.Component {
    responseFacebook(response) {
      console.log(response);
    }

    render() {
      return (
        <FacebookLogin
          appId="1088597931155576"
          autoLoad={true}
          fields="name,email,picture"
          scope="public_profile,user_friends,user_actions.books"
          callback={this.responseFacebook}
        />
      )
    }
  }
