RoR如何用于前端？

Question

I was reading an article titled The Secret Behind Twitter's Growth , and I noticed something that made me a little confused:

The third paragraph which gives some background began with this: "The popular Web programming language Ruby on Rails is responsible for the look and feel of Twitter's user interface ..." Now, I know that RoR is for back-end development, so how is it possible to use it in the user interface aka the “front end”?

Answer 1

You can display data from your database in your views.

You can use ERB(embedded ruby) inside of your HTML to display cool ruby coded front end stuff (the current date for example).

You can use all kinds of cool gems like(pagination) which sorts long lists into multiple pages etc.

And also; Ruby On Rails is not just backend, it's a framework where you can use practically any front-end languages/tools(Javascript, Coffeescript, HTML5, CSS, XML, AJAX, Angular.js, React.js, SCSS, LESS, you name the rest) aswell.

In short; The list is endless, you can do a lot to improve the user experience.

If you are really interested in this exact stuff, you can read the book 'The Ruby On Rails Tutorial' by Michael Hartl where you can build a copy of the Twitter website along with him. Then you will see exactly how Ruby on Rails helps improve the user experience. And you will learn a lot aswell :)
