It's crazy that 12.13.0 is now the latest long term support version of nodejs! At work today we discovered that when we all boot up a new terminal shell and run "node -v" to get the current node version, we would all get a different number! One person was on 12.13, one was on 11.15, one was on 10.something, and one guy was even using v6.4! We had to do something about this madness
Pro Tip: Use Async / Await With Act To Avoid Act Warnings in Jest / Enzyme Tests And Have Components Update Properly!
I was having a hard time recently writing jest + enzyme unit tests for a react.js project, and one of my colleagues saved the day with the await / async addition. In this post I'll go through what I was doing, what I tried that didn't work, and what we ultimately went with that fixed everything!
My team and I are working on a React project that runs in regular browsers, and we recently decided to use Cypress for end to end testing. It has an actually surprisingly nice you can use to write describe-it style test scripts that will load up a browser with any page on your site, click some things, interact with the dom, and then even do assertions that your page renders correctly. You can do "cypress run" to run your tests via the command line or "cypress open" to start this little application from which you can run all tests or just specific tests, and it creates this little sidebar that gives you a history of the commands it's running and details about what happened when things have failed. Anyway, yes Cypress is awesome, but that's not what thing blog post was supposed to be about...
Today at work someone presented on graphQL, and there was an interesting discussion among all the engineers in the room about it. There was been a few times where I have had the chance to learn about graphQL, and I feel like I often leave thinking, "hey, that's a cool" but then never actually start using it in my development. Welp, that has been somewhat of the case again. Lol
