You know that fear. The fear of changing something in your CSS. Deleting a CSS rule is a lesson in getting yourself to calm down, telling yourself that it’s OK, you are absolutely _sure_ that deleting that rule won’t change anything.

And only manual testing can assuage that fear. And yet, even then, you’re still frightened that you haven’t checked _everything_, and that you missed something. Not to mention that it’s amazingly boring.

Never fear again! Testing your CSS code, testing the _visual_ aspects of your code, is now possible, and I will show how. A slew of new Saas tools have come to the forefront which enable us to write tests that check that everything is the same that it was (even if we moved from BEM to CSS-in-JS).

So grab that keyboard, refactor your CSS, because writing tests for it is now possible!

Don’t Believe the Rumors: Writing Tests for CSS is Possible

ES Module support in Node v12 is not just a refinement of the support it has in Node v10, but is rather pointing to a direction in which Node and browser ES Modules converge into one system, a system which will enable ES modules to "just work" within the native npm ecosystem, without the need for transpilers or bundlers. 

This talk will examine this, and show how this will be possible in the upcoming years.

You Gotta Love Frontend

Don’t Believe the Rumors  Writing Tests for CSS is Possible

Testing Frontend code is painful. You can either do small unit tests that don't check a lot, or you have to use automation tools to test your code in a living browser. There is a third alternative, which can be a very natural way to test your code - run your frontend code under Node! The benefits are enormous - simple debugging, no need for transpiling and bundling, and no need to raise a server to run the tests.
