Login State

Share Login State between the Sub Domains for Meteor Apps (Support for static apps too)

Getting Started

This meteor package use for sharing login state information between apps hosted in different sub-domains. All apps are not necessory to be meteor apps. One app must be a meteor app and its login state can be share easialy across multiple sub-domains using this package.

On Meteor App

Inatall

meteor add meteorhacks:login-state

Configuration

Update settings.json as follows. You need to provide appropriate values for domain and cookineName fields.

Note: You must have update the domain field in settings.json, with the domain name which you need to share login state. Eg: When your domain name and landing page is mysite.com and app.mysite.com is your app subdomain and, also supports.mysite.com is the support forum, then you need to update domain field as .mysite.com.

{
  "public": {
    "loginState": {
      "domain": ".your-domain-name.com",
      "cookieName": "app-login-state-cookie-name"
    }
  }
}

On static app

Using custom JavaScript code

Create a JavaScript file as js/login_state.js or given a name as you want. After that update following code there.

LoginState = {};

LoginState.get = function(cookieName) {
  var loginState = getCookie(cookieName);
  if(loginState) {
    return JSON.parse(decodeURIComponent(loginState));
  } else {
    return false;
  }
};

function getCookie(cname) {
  var name = cname + "=";
  var ca = document.cookie.split(';');
  for(var i=0; i<ca.length; i++) {
      var c = ca[i];
      while (c.charAt(0)==' ') c = c.substring(1);
      if (c.indexOf(name) != -1) return c.substring(name.length,c.length);
  }
  return "";
}

Include it into your html document. Then you can call LoginState.get(cookieName) function to get login state by providing the correct cookie name.

Here's the sample code for that;

var loginState = LoginState.get("app-login-state-cookie-name");
if(loginState) {
  // the user has loggedIn to the meteor app
  // see the loginState Object for the addtional data
  // (append your code here!)
  console.log(loginState);
} else {
  // user has not loggedIn yet.
  // (append your code here!) 
}
