meteor - Race condition when going directly secured page -


i running race condition when unknown user trying access secured page.

iron-router code:

function secured() {     if ( meteor.user() == null ) {         meteor.loginwithlinkedin({         },function (err){             if(err){                 console.log("error when login linkedin."+json.stringify(err));             }         });     } }  router.map(function () {this.route('customer_researchrequest', {     before: secured,     waiton: waitonhuman,     path: '/research/request',     template: 'customer_researchrequest',     layouttemplate: 'customer_requestlayout' });});

on server:

    serviceconfiguration.configurations.remove({         service: 'linkedin'     });      serviceconfiguration.configurations.insert({... settings ...});

if user goes directly /research/request, there race condition.

  1. before condition fires
  2. (on client)serviceconfiguration.configurations has no configuration
  3. client has exception no linkedin service defined.
  4. server publishes serviceconfiguration.configurations client

at point, solution hard code in clientid , other linkedin config information linkedin authentication code ( yech ).

is there better more elegant/correct solution?

update #1: solution tweak meteor-linkedin package expects linkedin clientid option , not depend on serviceconfiguration.configuration. way clientid available.

edited address comment:

maybe different use of reactivity can help. set deferred redirect customer_researchrequest, first diverting user, bringing them up

a) have secured() save original destination path session. redirect page allow without security (or 'loading...' page), avoid #3
b) when login callback happens, save flag session, indicating #4 no longer true c) have deps.autorun redirect desired path when both flags become true.

someone else may know smarter way, (maybe waiton should test config) ...

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
