agent-detection

INFO

Agent detection is an small utility to detect commonly used user agents. It uses several approaches to detect user agents, most common userAgent chunk strings from the current userAgent String.

It also uses custom checks by feature in some situations, like the existence of documentMode property on internetExplorer 6-11 user agents.

This utility is intented to be used to add custom CSS classes to the HTML DOM element in order to style elements in different user agents, by doing for example:

.ua-ie .mycomponent { css only for ua-ie}

Code Example

Require the utility and use the public method to add the classes to element

  var AgentDetection  = require('agent-detection');
  var ag = new AgentDetection();
  ag.addClasses();

Also you can ask in your javascript code for an specific userAgent.

  var AgentDetection  = require('agent-detection');
  var ag = new AgentDetection();

  if( ag.isTouch() ) { ... }
