Answer 1

Late answer, but maybe it will help someone. For me the key to getting unique fb comments to render on a single page application was FB.XFBML.parse();

Each time I want to render unique comments:

1. Change the url, each fb comments thread is assigned to the specific url So I might have www.someurl.com/#123, www.someurl.com/#456, www.someurl.com/#789, each with its own fb comment thread. In AngularJs this can be done with $location.hash('123');

2. Create a new fb-comments div, where 'number' equals '123', '456' or '789'

   <div class="fb-comments" data-href="http://someurl.com/#{{number}}" data-numposts="5" data-width="100%" data-colorscheme="light"> </div>

3. Call a function that executes the fb SDK

   function FBfun(path) { setTimeout(function() { // I'm executing this just slightly after step 2 completes window.fbAsyncInit = function() { FB.init({ appId : '123456789123', xfbml : true, version : 'v2.2' }); }; (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')); FB.XFBML.parse(); // This is key for all this to work! }, 100); }

i added the script to app.js like

   initializeFB: function () {
        if (!isFBInitialized.isInitialized) {

            FB.init({
                appId: 'xxxxxxxxxxxx',
                appSecret: 'xxxxxxxxxxxxxxx',
                // App ID from the app dashboard
                channelUrl: '//mysite//channel.html', // Channel file for x-domain comms
                status: true,                                 // Check Facebook Login status
                cookie: true, // enable cookies to allow the server to access the session
                xfbml: true                                  // Look for social XFBML plugins on the page to be parsed
            });



            (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/all.js";
                fjs.parentNode.insertBefore(js, fjs);
            }(document, 'script', 'facebook-jssdk'));

            // Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
            // for any auth related change, such as login, logout or session refresh. This means that
            // whenever someone who was previously logged out tries to log in again, the correct case below 
            // will be handled. 
            FB.Event.subscribe('auth.authResponseChange', function (response) {
                // Here we specify what we do with the response anytime this event occurs. 
                if (response.status === 'connected') {
                    // The response object is returned with a status field that lets the app know the current
                    // login status of the person. In this case, we're handling the situation where they 
                    // have logged in to the app.
                    testFBAPI();
                } else if (response.status === 'not_authorized') {
                    // In this case, the person is logged into Facebook, but not into the app, so we call
                    // FB.login() to prompt them to do so. 
                    // In real-life usage, you wouldn't want to immediately prompt someone to login 
                    // like this, for two reasons:
                    // (1) JavaScript created popup windows are blocked by most browsers unless they 
                    // result from direct user interaction (such as a mouse click)
                    // (2) it is a bad experience to be continually prompted to login upon page load.
                    FB.login();
                } else {
                    // In this case, the person is not logged into Facebook, so we call the login() 
                    // function to prompt them to do so. Note that at this stage there is no indication
                    // of whether they are logged into the app. If they aren't then they'll see the Login
                    // dialog right after they log in to Facebook. 
                    // The same caveats as above apply to the FB.login() call here.
                    FB.login();
                }
            });

            isFBInitialized.isInitialized = true;
        }
    },

and call it in viewattached as

             app.initializeFB();

then it works well

Step 3 for my React app become (more linter friendly):

componentDidMount() {
    window.fbAsyncInit = () => {
        window.FB.init({
            appId: '572831199822299',
            xfbml: true,
            version: 'v4.0',
        });
    };

    (function (d, s, id) {
        const fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) { return; }
        const js = d.createElement(s);
        js.id = id;
        js.src = '//connect.facebook.net/ru_RU/sdk.js';
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));

    setTimeout(() => {
        window.FB.XFBML.parse();
    }, 100);
}
