My first time using React 16.0
September 27th, 2017
Yesterday I started working on a new React project which I am calling
for the time being
React Universal Blog. I set up my basic workflow, directory
structure, and files. I set up for
Jest testing, initially mocking out
stylesheets and images to make sure everything was working properly. Later I’ll
switch over to
mocking CSS Modules, because I use them with
not necessary to do that unless you intend to use
Jest Snapshot Testing, and I
do! I really want to check it out, and it just makes sense when you do
CSS Modules in
But that’s not why I am writing this post. I started this new project yesterday. And guess what big event took place yesterday! React 16.0 was released! And guess what happened in my project. I installed React 16.0.
Before I realized all this, I decided to make sure that my
was working, so today I typed
npm run test in Terminal. This is
what was printed out to the
> email@example.com test /Users/mariacam/Development/react-universal-blog-app > jest PASS src/sum.test.js PASS src/App.test.js ● Console console.error node_modules/fbjs/lib/warning.js:33 Warning: React depends on requestAnimationFrame. Make sure that you load a polyfill in older browsers. http://fb.me/react-polyfills Test Suites: 2 passed, 2 total Tests: 2 passed, 2 total Snapshots: 0 total Time: 1.669s Ran all test suites.
Notice something different?

That’s what reminded me that React 16.0 was released yesterday, and that my project must be using it! I wonder what other new goodies I will encounter!
