Web Tools Weekly
What a Tool!

Issue #253  (caniuse.com, Uncats, Testing/Debugging, Build/Deploy)

Most, if not all of you, will be familiar with the website caniuse.com. It's easily the best place to find browser support information for various web technologies.

One nice thing about the site is it's customization features. You can access these using the "Settings" button (next to the cog icon) beside the search field. Some of the things you can do using the settings include:

  • Specify browsers you want listed in the results by selecting or deselecting individual browsers, or by sliding the "Min. browser usage" percentage indicator.
  • Add a "Usage source" by specifying a geographic location (country, continent, etc) or by importing your Google Analytics data (which I haven't tried, but sounds pretty cool)
  • Add multiple custom "browser sets", which you can save for later so you can switch between them as needed. For example, you could do a mobile-only browser set.
  • Specify technology categories to list (CSS, JS, JS APIs, etc.)
Even within each of those features there are more settings and customizations you can make that I haven't mentioned here. There's quite a bit you can do, and some of these settings will even modify the URL so that what you select can be shared with others via deep linking.

I don't recall seeing an extensive article or tutorial covering caniuse.com hacks and tips like this, but that might make for a good post.
