Do you know which web browser the users of your site are using right now? You should.
There are people who track global market share of different web browsers and provide that data to the public, so you can know that 58% of the world is using Internet Explorer, for example.
Maybe the most well known is Net Market Share.
But I'm talking about just your users. Are you tracking the browsers being used by the people who are visiting and using the application for which you are responsible? It is valuable data that can be used for both planning and debugging purposes.
For amphibian.com, I collect the User-Agent strings from the browsers that visit the site. The User-Agent is a bit of text that all browsers send to the servers with each request. It doesn't identify you personally, but it does tell the server the product name and version (like Chrome 40) and the layout engine name and version.
If you want to see what your browser says it is, just go to http://whatsmyuseragent.com/ and it will tell you.
|What are some of these?|
Have a look at this site if you want to see a rather exhaustive list of possible agents: Zytrax.com Browser IDs.
Usage is simple.
var parser = new UAParser(); var r = parser.setUA("some user-agent string").getResult(); console.log(r.browser.name); // "Chrome", "Firefox", etc. console.log(r.browser.version); // the complete version, like 40.0.2214.115 console.log(r.browser.major); // just the version whole number, like 40 console.log(r.os.name); // "Windows", "Linux", etc. console.log(r.os.version); // 95, ME, 7, 8, etc. console.log(r.engine.name); // "WebKit", "Gecko", etc. console.log(r.engine.version); // something like 537.36
After creating the UAParser object, get an object that represents the result of a parse by calling setUA and passing in a string. The result object contains a nicely organized breakdown of the agent. Easy!
Why don't you take your user agent over to my comic now and see what the frogs are up to today?
