Question

Well i don't know if it's possible but i want something that works like {{#if currentUser}} bla bla bla {{/if}} but with facebook only. It's for a custom facebook comments (i don't like the official one)

Answer 1

When you store a user that logs in with Facebook your users collection obtains a field called services. Here is how I handle images:

serviceImageUser = function () {

    var user= Meteor.user();

    if(!user)
        return;

    if (user.services)
    {
        if (user.services.facebook)
            return user.services.facebook.picture;
        if (user.services.twitter)
            return user.services.twitter.profile_image_url;
        if (user.services.google)
            return user.services.google.picture;
        if (user.services.instagram)
            return user.services.instagram.profile_picture;
    }
    else
    {
        return user.profile.userProfile.picture;
    }
};

You need to add 2 packages to get the Facebook login functionality working.

meteor add accounts-facebook
meteor add service-configuration

The accounts-facebook plugin enables facebook login and service-configuration allows to store the setup for our Facebook app’s ids.

As for templates:

<template name="name">
    {{#if currentUser}}
        {{currentUser.services.facebook.picture}}
    {{/if}}
</template>
