Vue 2.x directive - automatic focus when element gets visible (works well with v-show)
Vue.directive('focus', {
update: function (el) {
if (!el.offsetParent) { // element not visible
el.dataset.focused=false;
} else if (el.dataset.focused!=="true") { // focus hasn't been forced yet
el.dataset.focused=true;
el.focus();
}
}
})

How to use a single Logentries account on Heroku

If you have multiple applications on Heroku and would like to use a single Logentries account for all of them, this is how you do it. Basically, do not use add-ons, and send all drains to your account.

  • In your Logentries account, click on Add Log
  • Select Manual
  • In the form that appears, input the following:
    • Log Name: access.log
    • Select Set: new set named myapp-{environment}, for instance myapp-staging (at least, this is how I like to name my entries)
    • Select the Plain TCP, UDP - logs are sent via syslog option
  • Click on Create Log Token
