I'm getting started with ReactJS, NodeJS, Webpack, and the Facebook SDK for user authentication. All these technologies and their associated software engineering principles/best practices are relatively new to me (even JavaScript is pretty new to me).
I've followed the tutorial here and I've got Facebook authentication working great! But the way this tutorial content is structured, it looks to me like the SDK is designed only to expect the FB status response handlers to be included in the raw page HTML just inside the <body> tag. The following in particular references this:
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
This strategy strikes me as imperfect and hard to integrate with React components. Is there a way to relocate the Facebook login/authentication code and Facebook status update handlers from the HTML, for example, into scripts being bundled with React code via Webpack? Is it possible? Part of the reason for my question is that if I understand correctly, for my Facebook status update handler to be able to update my React components' state, that handler needs to be part of a component to have access to the relevant React component this.setState(...) function.
Am I even thinking about this correctly?

Reset to default 28Yes you are right and can very well integrate facebook login with react component.
A sample login component can be like this -
import React from 'react';
class LoginComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
};
}
loadFbLoginApi() {
window.fbAsyncInit = function() {
FB.init({
appId : FB_APP_ID,
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : 'v2.5' // use version 2.1
});
};
console.log("Loading fb api");
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/sdk.js";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
}
componentDidMount() {
this.loadFbLoginApi();
}
testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Successful login for: ' + response.name);
document.getElementById('status').innerHTML =
'Thanks for logging in, ' + response.name + '!';
});
}
statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);
if (response.status === 'connected') {
this.testAPI();
} else if (response.status === 'not_authorized') {
console.log("Please log into this app.");
} else {
console.log("Please log into this facebook.");
}
}
checkLoginState() {
FB.getLoginStatus(function(response) {
this.statusChangeCallback(response);
}.bind(this));
}
handleFBLogin() {
FB.login(this.checkLoginState());
}
render() {
return (
<div>
<MyButton
classNames = "btn-facebook"
id = "btn-social-login"
whenClicked = {this.handleFBLogin}
>
<span className="fa fa-facebook"></span> Sign in with Facebook
</MyButton>
</div>
);
}
}
export default LoginComponent;
When response status received is connected then it means user is logged in via Facebook and you can set state on your component to reflect that. e.g
response.status === 'connected'
this.setState({userLoggedIn:true});
I am using a custom button component (MyButton) in React which you can very easily create.
What about using the npm react-facebook? It includes a few components like "Initialize" (this is for expose the FB Api in a function children) or a LoginButton that handles the facebook pop up screen for login, or if you wanna make your own button you can use component Login. Just provide the facebook app id to the FacebookProvider component at the root of you project (called only once) and use the components that providea such great node module as react-facebook.

I have found another way to load fb-sdk file in webpack, using npm package: react-load-script
Follow this simple package to achieve the same: https://www.npmjs.com/package/react-load-script
