# Free Preview: Essential Ruby Libraries

## Introduction

01:51

Ruby is more than just a language, it is a whole ecosystem. The power of the language is greatly multiplied by the thousands of gems freely available from the public gem server, but there are also some amazing tools that come already bundled with Ruby.

In this course, you'll learn how to use the standard libraries that come bundled in with every installation of Ruby. Tuts+ instructor José Mota will teach you how to:

• manipulate YAML, CSV and JSON data
• apply delegation for better code reuse
• fetch content from the web using Net::HTTP and the URI library
• manage files

You'll be amazed how much can be accomplished using only the standard Ruby libraries! Each library will be taught with simple examples and exercises that you can adapt for your own programming problems.
