How it actually feels to write JavaScript in 2016

Oct 4, 2016 · 2 min read
Yeah, it’s a piece of cake.

Hey, I need to create a page that displays the latest activity from the users, so I just need to get the data from the REST endpoint and display it in some sort of filterable table, and update it if anything changes in the server. I was thinking maybe using jQuery to fetch and display the data?

-Sure, you could still use jQuery. But if you’re ever planning to do something more complicated on the frontend you should probably try React. It will be a big benefit for you in the future.

-Sounds great. How can i start with React?

-The easiest way is to run npm install create-react-app -g in your terminal and you can start with a project right away.

-Cool, so you’re telling me that I don’t need any additional setup?


-Do I need to install any special IDE like Visual Studio, Android Studio, or Xcode?

-Nope, just create your app with create-react-app my-cool-app and you’re good to go.

-But what about extra dependencies? Do I maybe need to install Java on my machine? Maybe I also need Maven, Gradle, CocoaPods, or maybe I need to download some extra 20gb SDK?

-Nope, just cd into your app and start it with npm start. That’s it.

-But do I have to build my app and wait for a long rebuild every time i change something?

-Nope. If you do a change the page will automatically refresh for you. If you change some CSS it will be live-reloaded for you, without doing a full page refresh.

-Sounds very useful! I think it can speed up my development process a bit. But wait, what do i do if i ever want to deploy a production version of my website? Because no one is *actually* deploying an unminified version of index.html, app.css, and main.js in production anymore, right?

-Yup, you’re right. If you ever want to deploy a production version of your site just run npm run build and everything that you need will be in your /build folder. Minified, optimised, and ready for deployment.

-Thanks dude, that was very helpful.
