Introducing Web Application Development in Rails

[ 8 ]

Why Bootstrap with Rails?

Rails is one the most popular Ruby frameworks which is currently at its peak,

both in terms of demand and technology trend. With more than 3,100 members

contributing to its development, and tens of thousands of applications already built

using it, Rails has created a standard for every other framework in the Web today.

Rails was initially developed by David Heinemeier Hansson in 2003 to ease his

own development process in Ruby. Later, he became generous enough to release

Rails to the open source community. Today, it is popularly known as Ruby on Rails.

Rails shortens the development life cycle by moving the focus from reinventing

the wheel to innovating new features. It is based on the convention of the

congurations principle, which means that if you follow the Rails conventions,

you would end up writing much less code than you would otherwise write.

Bootstrap, on the other hand, is one of the most popular frontend development

frameworks. It was initially developed at Twitter for some of its internal projects.

It makes the life of a novice web developer easier by providing most of the reusable

components that are already built and are ready to use. Bootstrap can be easily

integrated with a Rails development environment through various methods.

We can directly use the

.css les provided by the framework, or can extend it

through its Sass version and let Rails compile it.

Sass is a CSS preprocessor that brings logic and functionality into CSS.

It includes features like variables, functions, mixins, and others. Using

the Sass version of Bootstrap is a recommended method in Rails. It

gives various options to customize Bootstrap's default styles easily.

Bootstrap also provides various JavaScript components that can be used by those

who don't have any real JavaScript knowledge. These components are required in

almost every modern website being built today.

Bootstrap with Rails is a deadly combination. You can build applications faster

and invest more time to think about functionality, rather than rewrite codes.

Setting up a Todo application in Rails

Since this book is targeted for Rails developers, I assume that you already have

basic knowledge of Rails development. You should also have Rails and Ruby

installed in your machine to start with.
