You know Rails well. You've been using it for a while, at your job and for your own projects. You're got comfortable using jQuery on the frontend, and come to know its gotchas. Maybe you've dabbled in Backbone or looked at Angular.

Recently, you came across React. Everyone's talking about it. Every other job post on Hacker News mentions it. So you decide to up your frontend game and learn it. 

Maybe you've picked up the basics from some docs, blog posts and Youtube videos. It seems cool. But you're not sure if it's worth using it with Rails just yet.

It's all too confusing and intimidating. You thought React is just a frontend library, and you could just drop it in like jQuery. But then what's all this stuff about Babel, Webpack, ES6, Redux and five different gems for integrating with Rails.

You have more questions than answers now. 

Which gem should I use for integrating React in a Rails app?
Can I still use the asset pipeline?
Do I need to use Browserify or Webpack?
Do I need to make an API to use React?

It's too confusing, so you give up.

"jQuery works fine anyway", you think to yourself.

But you know you need to keep up with the times.

You might be able to get by without React for a few more months, but you know the next client or the next employer will want you to use it.

You won't be able to get that job or expand your freelance business unless you add React to your toolbelt.

You must learn React to make sure you get better work and earn more.

Fortunately, there’s a way to address this: by learning at least enough basics to be able to start using React with Rails. You won't become a pro overnight, you can get started very quickly today.

The Free React on Rails Course

How? With this new video course that teaches you just the right stuff to start using React with Rails. It’s called The Free React on Rails Course. It’ll teach you how you can start incorporating React into your Rails apps, starting from the basic concepts behind React to building a Rails 5 calendar appointments app with it.

It’s not enough to simply learn React. You need to be able to make React work well with a backend system - in your case, a Rails app. This free video course will teach you enough so that you can start upgrading your Rails frontend with the latest hotness in JavaScript land.

Why is learning React important for a Rails developer?

  • Web UIs have matured a lot over the last decade. We're doing more complex things to build better user experiences on the web. jQuery has served well but even a medium-sized project can now quickly turn into the Flying Spaghetti Monster. React offers a simple yet powerful alternative to spaghetti code.

  • Even if React itself is replaced by something else, the concept of reactive UI - UI as functional components is here to stay. So it'll help you a great deal to learn to use it.

  • In many ways React is to the modern frontend, what Rails is to the backend - there are many alternatives, but React has the best combination of simplicity, power and popularity to make it a great choice.

  • There's a huge and growing market demand for React developers. Many companies are moving their frontend away from plain Rails templates and jQuery over to React, so learning React would give you a unique advantage over others vying for the same jobs.

  • Once you learn to use React with Rails, you can also use React Native to build mobile apps for the same API. This way, your investment in learning React gives you the chance to easily build cross-platform apps.
